Randomized Controlled Trial

Back Clinic Randomized Controlled Trial Chiropractic and Functional Medicine Team. A study in which the participants are divided by chance into separate groups that compare different treatments or other interventions. Using the chance to divide people into groups means that the groups will be similar and that the effects of the treatments they receive can be compared more fairly.

At the time of the trial, it is not known which treatment is best. A Randomized Controlled Trial or (RCT) design randomly assigns participants into an experimental group or a control group. As the study is conducted, the only expected difference from the control and experimental groups in a randomized controlled trial (RCT) is the outcome variable being studied.

Advantages

  • Easier to blind/mask than from observational studies
  • Good randomization washes out any population bias
  • Populations of participating individuals are clearly identified
  • Results can be analyzed with well known statistical tools

Disadvantages

  • Does not reveal causation
  • Expensive in time and money
  • Loss to follow-up attributed to treatment
  • Volunteer biases: the population that participates may not be representative of the whole

Work Injury Health Guidelines for Low Back Pain in El Paso, TX

Work Injury Health Guidelines for Low Back Pain in El Paso, TX

Low back pain represents one of the most common complaints in healthcare settings. While various injuries and conditions associated with the musculoskeletal and nervous system can cause low back pain, many healthcare professionals believe that work injury may have a prevalent connection to low back pain. For instance, improper posture and repetitive movements may often cause work-related injuries. In other cases, environmental accidents at work may cause work injuries. In any case, diagnosing the source of a patient’s low back pain to correctly determine which would be the best treatment method to restore the individual’s original health and wellness is generally challenging.

 

First and foremost, getting the right doctors for your specific source of low back pain is essential for finding relief from your symptoms. Many healthcare professionals are qualified and experienced in treating work-related low back pain, including doctors of chiropractic or chiropractors. As a result, several work injury treatment guidelines have been established to manage low back pain in healthcare settings. Chiropractic care focuses on diagnosing, treating, and preventing various injuries and conditions, such as LBP, associated with the musculoskeletal and nervous system. By carefully correcting the misalignment of the spine, chiropractic care can help improve symptoms of low back pain, among other symptoms. The purpose of the following article is to discuss occupational health guidelines for the management of low back pain.

 

Occupational Health Guidelines for the Management of Low Back Pain: an International Comparison

 

Abstract

 

  • Background: The enormous socioeconomic burden of low back pain emphasizes the need to manage this problem, especially in an occupational context effectively. To address this, occupational guidelines have been issued in various countries.
  • Aims: To compare available international guidelines for managing low back pain in an occupational health care setting.
  • Methods: The guidelines were compared regarding generally accepted quality criteria using the AGREE instrument and also summarised regarding the guideline committee, the presentation, the target group, and assessment and management recommendations (that is, advice, return to work strategy, and treatment).
  • Results and Conclusions: The results show that the guidelines variously met the quality criteria. Common flaws concerned the absence of proper external reviewing in the development process, lack of attention to organizational barriers and cost implications, and lack of information on the extent to which editors and developers were independent. There was general agreement on numerous issues fundamental to occupational health management of back pain. The assessment recommendations included diagnostic triage, screening for red flags and neurological problems, and identifying potential psychosocial and workplace barriers to recovery. The guidelines also agreed on advice that low back pain is a self-limiting condition and that remaining at work or an early (gradual) return to work, if necessary with modified duties, should be encouraged and supported.

 

Dr. Alex Jimenez’s Insight

Low back pain is one of the most prevalent health issues treated in chiropractic offices. Although the following article describes low back pain as a self limiting condition, the cause of an individual’s LBP can also trigger debilitating and severe pain and discomfort of left untreated. It’s important for an individual with symptoms of low back pain to seek proper treatment with a chiropractor to properly diagnose and treat their health issues as well as prevent them from returning in the future. Patients who experience low back pain for more than 3 months are less than 3 percent likely to return to work. Chiropractic care is a safe and effective alternative treatment option which can help restore the original function of the spine. Furthermore, a doctor of chiropractic, or chiropractor, can provide lifestyle modifications, such as nutritional and fitness advice, to speed up the patient’s recovery process. Healing through movement is essential for LBP recovery.

 

Low back pain (LBP) is one of the industrial countries’ most common health problems. Despite its benign nature and sound course, LBP is commonly associated with incapacity, productivity loss due to sick leave, and high societal costs.[1]

 

Because of that impact, there is an obvious need for effective management strategies based on scientific evidence derived from studies of sound methodological quality. Usually, these are randomized controlled trials (RCTs) on the effectiveness of therapeutic interventions, diagnostic studies, or prospective observational studies on risk factors or side effects. The scientific evidence, summarised in systematic reviews and meta-analyses, provides a solid basis for guidelines on managing LBP. In a previous paper, Koes et al. compared various existing clinical guidelines for managing LBP targeted at primary healthcare professionals, showing a considerable commonality.[2]

 

The problems in occupational health care are different. Management focuses mainly on counseling the worker with LBP and addressing the issues of assisting them to continue working or return to work (RTW) after sick listing. However, LBP is also an important issue in occupational health care because of the associated incapacity for work, productivity loss, and sick leave. Several guidelines, or sections of guidelines, have now been published dealing with the specific issues of management in an occupational health care setting. Since the evidence is international, it would be expected that the recommendations of different occupational guidelines for LBP would be more or less similar. However, it is not clear whether the guidelines meet currently accepted quality criteria.

 

This paper critically appraises available occupational guidelines on managing LBP and compares their assessment and management recommendations.

 

Main Messages

 

  • In various countries, occupational health guidelines are issued to improve the management of low back pain in an occupational context.
  • Common flaws of these guidelines concern the absence of proper external reviewing in the development process, lack of attention to organizational barriers and cost implications, and lack of information on the independence of editors and developers.
  • In general, the assessment recommendations in the guidelines consisted of diagnostic triage, screening for red flags and neurological problems, and identifying potential psychosocial and workplace barriers to recovery.
  • There is general agreement on advice that low back pain is a self-limiting condition and that remaining at work or an early (gradual) return to work, if necessary with modified duties, should be encouraged and supported.

 

Methods

 

Guidelines on the occupational health management of LBP were retrieved from the authors’ personal files. Retrieval was checked by a Medline search using the keywords low back pain, guidelines, and occupational up to October 2001, and personal communication with experts in the field. Policies had to meet the following inclusion criteria:

 

  • Guidelines aimed at managing workers with LBP (in occupational health care settings or addressing occupational issues) or separate sections of policies that dealt with these topics.
  • Guidelines are available in English or Dutch (or translated into these languages).

 

The exclusion criteria were:

 

  • Guidelines on primary prevention (that is, prevention before the onset of the symptoms) of work-related LBP (for example, lifting instructions for workers).
  • Clinical guidelines for the management of LBP in primary care.[2]

 

The quality of the included guidelines was appraised using the AGREE instrument, a generic tool designed primarily to help guideline developers and users assess the methodological quality of clinical practice guidelines.[3]

 

The AGREE instrument provides a framework for assessing the quality on 24 items (table 1), each rated on a four-point scale. The full operationalization is available on www.agreecollaboration.org.

 

Two reviewers (BS and HH) independently rated the quality of the guidelines and then met to discuss disagreements and to reach a consensus on the ratings. When they could not agree, a third reviewer (MvT) reconciled the remaining differences and decided on the ratings. To facilitate analysis in this review, ratings were transformed into dichotomous variables of whether each quality item was or was not met.

 

The assessment recommendations were summarised and compared to recommendations on advice, treatment, and return to work strategies. The selected guidelines were further characterized and reached regarding the guideline committee, the presentation of the procedure, the target group, and the extent to which the recommendations were based on available scientific evidence. All of this information was extracted directly from the published guidelines.

 

Policy Implications

 

  • The management of low back pain in occupational health care should follow evidence-based guidelines.
  • Future occupational guidelines for managing low back pain and updates of those guidelines should consider the criteria for proper development, implementation, and evaluation of approaches as suggested by the AGREE collaboration.

 

Results

 

Selection of Studies

 

Our search found ten guidelines, but four were excluded because they dealt with the management of LBP in primary care,[15] were aimed at the guidance of sick-listed employees in general (not specifically LBP),[16] were intended for the primary prevention of LBP at work,[17] or were not available in English or Dutch.[18] The final selection, therefore, consisted of the following six guidelines, listed by date of issue:

 

(1) Canada (Quebec). A scientific approach to the assessment and management of activity-related spinal disorders. A monograph for clinicians. Report of the Quebec Task Force on Spinal Disorders. Quebec Canada (1987).[4]

 

(2) Australia (Victoria). Guidelines for the management of employees with compensable low back pain. Victorian WorkCover Authority, Australia (1996).[5] (This is a revised version of guidelines developed by the South Australian WorkCover Corporation in October 1993.)

(6) the UK

 

(a)Occupational health guidelines for managing low back pain at work principal recommendations. Faculty of Occupational Medicine. UK (2000).[11]

 

(b)Occupational health guidelines for managing low back pain at work leaflet for practitioners. Faculty of Occupational Medicine. UK (2000).[12]

(d)The Back Book, The Stationery Office. UK (1996).[14]

Two guidelines (4 and 6) could not be evaluated independently from additional documents to which they refer (4bc, 6bd), so these documents were also included in the review.

 

Appraisal of the Quality of the Guidelines

 

Initially, there was an agreement between the two reviewers regarding 106 (77%) of the 138 item ratings. After two meetings, the consensus was reached for all but four items, which required adjudication by the third reviewer. Table 1 presents the final ratings.

 

All included guidelines presented the different options for managing LBP in occupational health. In five of the six policies, the overall objectives of the procedure were explicitly described,[46, 1014] the target users of the system were clearly defined,[514] easily identifiable key recommendations were included,[4, 614] or critical review criteria were presented for monitoring and audit purposes.[49, 1114]

 

The results of the AGREE appraisal showed that none of the guidelines paid sufficient attention to potential organizational barriers and cost implications in implementing the recommendations. It was also unclear for all included guidelines whether or not they were editorially independent of the funding body and whether or not there were conflicts of interest for the members of the guideline development committees. Furthermore, it was unclear for all guidelines whether experts had externally reviewed the policies before publication. Only the UK guideline clearly described the method used to formulate the recommendations and provided for updating the approach.[11]

 

Table 1 Ratings of the Occupational Health Guidelines

 

Development of the Guidelines

 

Table 2 presents background information on the development process of the guidelines.

 

The target users for the guidelines were physicians and other healthcare providers in the field of occupational healthcare. Several policies were also directed at informing employers, workers [68, 11, 14], or members of organizations interested in occupational health.[4] The Dutch guideline was only targeted at the occupational health physician.[10]

 

The guideline committees responsible for developing the guidelines were generally multidisciplinary, including disciplines like epidemiology, ergonomics, physiotherapy, general practice, occupational medicine, occupational therapy, orthopedics, and representatives of employers’ associations and trade unions. Chiropractic and osteopathic representatives were in the guideline committee of the New Zealand guidelines.[79] The Quebec task force (Canada) also included representatives of rehabilitation medicine, rheumatology, health economics, law, neurosurgery, biomechanical engineering, and library sciences. In contrast, the guideline committee of the Dutch guideline consisted only of occupational physicians.[10]

 

The guidelines were issued as a separate document,[4, 5, 10] as a chapter in a textbook,[6] or as several interrelated documents.[79, 1114]

 

The UK,[13] the USA,[6] and Canadian[4] guidelines provided information on the search strategy applied to the identification of relevant literature and the weighing of the evidence. On the other hand, the Dutch[10] and the Australian[5] guidelines supported their recommendations only by references. The New Zealand guidelines showed no direct links between suggestions and concerns [79]. The reader was referred to other literature for background information.

Patient Population and Diagnostic Recommendations

 

Although all guidelines focused on workers with LBP, it was often unclear whether they dealt with acute or chronic LBP or both. Acute and chronic LBP were often not defined, and cut-off points were given (for example, <3 months). It was usually unclear whether these referred to the onset of symptoms or absence from work. However, the Canadian guideline introduced a classification system (acute/subacute/ chronic) based on the distribution of claims of spinal disorders by time since absence from work.[4]

 

All guidelines distinguished specific and non-specific LBP. Specific LBP concerns the potentially serious red flag conditions like fractures, tumors, or infections, and the Dutch and UK guidelines also distinguish the radicular syndrome or nerve root pain.[1013] All procedures were consistent in their recommendations to take a clinical history and to carry out a physical examination, including neurological screening. In cases of suspected specific pathology (red flags), x-ray examinations were recommended by most guidelines. In addition, New Zealand and the US guideline also recommended an x-ray examination when symptoms did not improve after four weeks.[6, 9] The UK guideline stated that x-ray examinations are not indicated and do not assist occupational health management of the patient with LBP (distinct from any clinical indications).[1113]

 

Most guidelines considered psychosocial factors as yellow flags as obstacles to recovery that healthcare providers should address. The New Zealand[9] and UK guidelines [11, 12] explicitly listed factors and suggested questions to identify those psychosocial yellow flags.

 

All guidelines addressed the importance of the clinical history identifying physical and psychosocial workplace factors relevant to LBP, including physical demands of work (manual handling, lifting, bending, twisting, and exposure to whole-body vibration), accidents or injuries, and perceived difficulties in returning to work or relationships at work. The Dutch and the Canadian guidelines contained recommendations to carry out a workplace investigation[10] or an assessment of occupational skills when necessary.[4]

 

Summary of Recommendations for the Assessment of LBP

 

  • Diagnostic triage (non-specific LBP, radicular syndrome, specific LBP).
  • Exclude red flags and neurological screening.
  • Identify psychosocial factors and potential obstacles to recovery.
  • Identify workplace factors (physical and psychosocial) that may be related to the LBP problem and return to work.
  • X-Ray examinations are restricted to suspected cases of specific pathology.

 

Recommendations Regarding Information and Advice, Treatment, and Return to Work Strategies

 

Most guidelines recommended reassuring the employee and providing information about LBP’s self-limiting nature and good prognosis. Encouragement of return to ordinary activity as generally as possible was frequently advised.

 

In line with the recommendation to return to regular activity, all guidelines also stressed the importance of returning to work as rapidly as possible, even if there is still some LBP and, if necessary, starting with modified duties in more severe cases. Work duties could then be increased gradually (hours and tasks) until total return to work was reached. The US and Dutch guidelines provided detailed time schedules for return to work. The Dutch approach proposed a return to work within two weeks with an adaptation of duties when necessary.[10] The Dutch system also stressed the importance of time-contingent management about a return to work.[10] The US guideline proposed every attempt to maintain the patient at maximal levels of activity, including work activities; targets for disability duration in terms of return to work were given as 02 days with modified duties and 714 days if modified duties are not used/available.[6] In contrast to the others, the Canadian guideline advised return to work only when symptoms and functional restrictions had improved.[4]

 

The most frequently recommended treatment options in all the included guidelines were: medication for pain relief,[5, 7, 8] gradually progressive exercise programs,[6, 10] and multidisciplinary rehabilitation.[1013] The US guideline recommended referral within two weeks to an exercise program consisting of aerobic exercises, conditioning exercises for trunk muscles, and exercise quota.[6] The Dutch guideline recommended that if there is no progress within two weeks of work absence, workers should be referred to a graded activity program (gradually increasing exercises) and, if there is no improvement by four weeks, to a multidisciplinary rehabilitation program.[10] The UK guideline recommended that workers who have difficulty returning to regular occupational duties by 412 weeks should be referred to an active rehabilitation program. This rehabilitation program should include education, reassurance and advice, a progressive vigorous exercise and fitness program, and pain management according to behavioral principles; it should be embedded in an occupational setting and directed firmly toward a return to work.[11-13] Extensive lists of possible treatment options were presented in the guidelines of Canada and Australia [4, 5], although most of these were not based on scientific evidence.

 

Summary of Recommendations Regarding Information, Advice, Return to Work Measures, and Treatment in Workers with LBP

 

  • Reassure the worker and provide adequate information about LBP’s self-limiting nature and good prognosis.
  • Advise the worker to continue ordinary activities or to return to regular exercise and work as soon as possible, even if there is still some pain.
  • Most workers with LBP return to more or less regular duties quite rapidly. Consider temporary adaptations of work duties (hours/tasks) only when necessary.
  • When a worker fails to return to work within 212 weeks (there is considerable variation in the time scale in different guidelines), refer them to a gradually increasing exercise program, or multidisciplinary rehabilitation (exercises, education, reassurance, and pain management following behavioral principles). These rehabilitation programs
    should be embedded in an occupational setting.

 

Discussion

 

The management of LBP in an occupational health setting must address the relation between low back complaints and work and develop strategies aimed at a safe return to work. This review compared available occupational health guidelines from various countries. Policies are rarely indexed in Medline, so when searching for guidelines, we had to rely primarily on personal files and personal communication.

 

Quality Aspects and Development Process of the Guidelines

 

The assessment by the AGREE instrument[3] showed some differences in the quality of the guidelines reviewed, which may partly reflect the variation in the dates of development and publication of the guidelines. The Canadian guideline, for example, was published in 1987 and the Australian guideline in 1996.[4, 5] The other guidelines were more recent and incorporated a more extensive evidence base and more up to date guideline methodology.

 

Several common flaws related to the development process of the guidelines were shown by the assessment by the AGREE instrument. Firstly, it is important to make clear whether a guideline is editorially independent from the funding body, and whether there are conflicts of interest for the members of the guideline committee. None of the included guidelines clearly reported these issues. Further, reported external review of the guideline by clinical and methodological experts prior to publication was also lacking in all guidelines included in this review.

 

Several guidelines provided comprehensive information on the way relevant literature was searched and translated into recommendations.[4, 6, 11, 13] Other guidelines supported their recommendations by references,[5, 7, 9, 10] but this does not permit assessment of the robustness of the guidelines or their recommendations.

 

Guidelines depend on the scientific evidence, which changes over time, and it is striking that only one guideline provided for future update.[11, 12] Possibly there are updates planned for the other guidelines but they are not explicitly stated (and conversely stating there will be future update does not mean it will actually occur). This lack of reporting may also hold true for other AGREE criteria that we rated negatively. The use of the AGREE framework as a guide for both the development and the reporting of guidelines should help to improve the quality of future guidelines.

 

Assessment and Management of LBP

 

The diagnostic procedures recommended in the occupational health guidelines were largely similar to the recommendations of clinical guidelines,[2] and, logically, the main difference was the emphasis on addressing occupational issues. The reported methods for addressing workplace factors in the assessment of LBP of the individual worker concerned the identification of difficult tasks, risk factors, and obstacles for return to work by occupational histories. Obviously, these obstacles for return to work not only concern physical load factors, but also work related psychosocial problems regarding responsibilities, cooperation with co-workers, and the social atmosphere at the workplace.[10] Screening for work related psychosocial yellow flags may help to identify those workers who are at risk for chronic pain and disability.[1113]

 

A potentially important feature of the guidelines is that they were consistent regarding their recommendations to reassure the employee with LBP, and to encourage and support return to work even with some persisting symptoms. There is general consensus that most workers do not have to wait until they are completely free of pain before returning to work. The lists of treatment options provided by the Canadian and Australian guidelines may reflect the lack of evidence at that time,[4, 5] leaving users of the guidelines to choose for themselves. It is, however, questionable whether such lists really contribute to improved care, and in our view guideline recommendations should be based on sound scientific evidence.

 

The US, Dutch, and UK occupational guidelines[6, 1013] recommend that active multidisciplinary treatment is the most promising intervention for return to work, and this is supported by strong evidence from RCTs.[19, 20] However, more research is still needed to identify the optimum content and intensity of those treatment packages.[13, 21]

 

Despite some evidence for a contribution of workplace factors in the aetiology of LBP,[22] systematic approaches for workplace adaptations are lacking, and are not offered as recommendations in the guidelines. Perhaps this represents a lack of confidence in the evidence on the overall impact of workplace factors, a difficulty of translation into practical guidance, or because these issues are confounded with local legislation (which was hinted at in the UK guideline[11]). It may be that the participatory ergonomics intervention, which proposes consultations with the worker, the employer, and an ergonomist, will turn out to be a useful return to work intervention.[23, 24] The potential value of getting all the players onside[25] was stressed in the Dutch and the UK guidelines,[1113] but further evaluation of this approach and its implementation is required.

 

Development of Future Guidelines in Occupational Health Care

 

The purpose of this review was to give both an overview and a critical appraisal of occupational guidelines for the management of LBP. The critical appraisal of the guidelines is meant to help direct future development and planned updates of guide- lines. In the still emerging field of guideline methodology we consider all past initiatives as laudable; we recognise the need for clinical guidance, and appreciate that guidelines developers cannot wait for research to provide all the methodology and evidence required. However, there is room for improvement and future guidelines and updates should consider the criteria for proper development, implementation, and evaluation of guidelines as suggested by the AGREE collaboration.

 

The implementation of the guidelines is beyond the scope of this review, but it was noted that none of the guideline documents specifically described implementation strategies, so it is uncertain to what extent the target groups may have been reached, and what effects that may have had. This may be a fruitful area for further research.

 

The very existence of these occupational health guidelines shows that existing primary care clinical guidelines for LBP2 are considered inappropriate or insufficient for occupational health care. There is a clear perception internationally that the needs of the worker experiencing back pain are intrinsically linked to a variety of occupational issues not covered by usual primary care guidance and, consequently, practice. What emerges is that, despite the methodological flaws, considerable agreement is evident on a range of fundamental occupational health strategies for managing the worker with back pain, some of which are innovative and challenge previously held views. There is agreement on the fundamental message that prolonged work loss is detrimental, and that early work return should be encouraged and facilitated; there is no need to wait for complete symptom resolution. Although the recommended strategies vary somewhat, there is considerable agreement on the value of positive reassurance and advice, availability of (temporary) modified work, addressing workplace factors (getting all the players onside), and rehabilitation for workers having difficulty returning to work.

In conclusion, symptoms of low back pain are one of the most common health issues associated with work injuries. Because of it, several occupational health guidelines have been established for the management of low back pain. Chiropractic care, among other treatment methods, may be utilized in order to help the patient find relief from their LBP. Furthermore, the article above demonstrated the safety and effectiveness of a variety of traditional as well as alternative treatment options in the diagnosis, treatment and prevention of a variety of low back pain cases. However, further research studies are required in order to properly determine the efficiency of each individual treatment method.

According to statistics, approximately 80% of people will experience symptoms of back pain at least once throughout their lifetimes. Back pain is a common complaint which can result due to a variety of injuries and/or conditions. Often times, the natural degeneration of the spine with age can cause back pain. Herniated discs occur when the soft, gel-like center of an intervertebral disc pushes through a tear in its surrounding, outer ring of cartilage, compressing and irritating the nerve roots. Disc herniations most commonly occur along the lower back, or lumbar spine, but they may also occur along the cervical spine, or neck. The impingement of the nerves found in the low back due to injury and/or an aggravated condition can lead to symptoms of sciatica.

Spinal Manipulation vs. Mobilization for Cervicogenic Headache in El Paso, TX

A primary headache is characterized as head pain caused by a headache disorder itself. The three types of primary headache disorders include, migraine, tension-type headaches and cluster headaches. Head pain is a painful and debilitating symptom that can also occur as a result of another underlying cause. A secondary headache is characterized as head pain which occurs due to an injury and/or condition. A spinal misalignment, or subluxation, along the cervical spine, or neck, is commonly associated with a variety of headache symptoms.

 

Cervicogenic headache is a secondary headache caused by an injury and/or condition affecting the surrounding structures of the cervical spine, or neck. Many healthcare professionals will recommend the use of drugs/medications to help improve headache, however, several alternative treatment options can be safely and effectively used to treat secondary headaches. The purpose of the following article is to demonstrate the impact of upper cervical and upper thoracic manipulation versus mobilization and exercise in patients with cervicogenic headache.

 

Upper Cervical and Upper Thoracic Manipulation Versus Mobilization and Exercise in Patients with Cervicogenic Headache: a Multi-Center Randomized Clinical Trial

 

Abstract

 

  • Background: Although commonly utilized interventions, no studies have directly compared the effectiveness of cervical and thoracic manipulation to mobilization and exercise in individuals with cervicogenic headache (CH). The purpose of this study was to compare the effects of manipulation to mobilization and exercise in individuals with CH.
  • Methods: One hundred and ten participants (n?=?110) with CH were randomized to receive both cervical and thoracic manipulation (n?=?58) or mobilization and exercise (n?=?52). The primary outcome was headache intensity as measured by the Numeric Pain Rating Scale (NPRS). Secondary outcomes included headache frequency, headache duration, disability as measured by the Neck Disability Index (NDI), medication intake, and the Global Rating of Change (GRC). The treatment period was 4 weeks with follow-up assessment at 1 week, 4 weeks, and 3 months after initial treatment session. The primary aim was examined with a 2-way mixed-model analysis of variance (ANOVA), with treatment group (manipulation versus mobilization and exercise) as the between subjects variable and time (baseline, 1 week, 4 weeks and 3 months) as the within subjects variable.
  • Results: The 2X4 ANOVA demonstrated that individuals with CH who received both cervical and thoracic manipulation experienced significantly greater reductions in headache intensity (p?<?0.001) and disability (p?<?0.001) than those who received mobilization and exercise at a 3-month follow-up. Individuals in the upper cervical and upper thoracic manipulation group also experienced less frequent headaches and shorter duration of headaches at each follow-up period (p?<?0.001 for all). Additionally, patient perceived improvement was significantly greater at 1 and 4-week follow-up periods in favor of the manipulation group (p?<?0.001).
  • Conclusions: Six to eight sessions of upper cervical and upper thoracic manipulation were shown to be more effective than mobilization and exercise in patients with CH, and the effects were maintained at 3 months.
  • Trial registration: NCT01580280 April 16, 2012.

Dr. Alex Jimenez’s Insight

In comparison to primary headache, such as migraine, cluster headache and tension-type headache, secondary headache is characterized as head pain caused by another illness or physical issue. In the case of cervicogenic headache, the cause of head pain is due to an injury and/or condition along the cervical spine and its surrounding structures, including the vertebrae, intervertebral discs and soft tissues. In addition, many healthcare professionals believe that primary headache can be associated with health issues in the cervical spine, or neck. Cervicogenic headache treatment should target the source of the symptoms and it can vary depending on the patient. Chiropractic care utilizes spinal adjustments and manual manipulations to carefully restore the original structure and function of the spine, helping to reduce stress and pressure in order to improve cervicogenic headache symptoms, among other type of headache. Chiropractic care can also be utilized to help treat primary headaches, such as migraines.

 

Background

 

The International Classification of Headache Disorders defines cervicogenic headache (CH) as, �headache caused by a disorder of the cervical spine and its component bony, disc, and/or soft tissue elements, usually but not invariably accompanied by neck pain.� [1] (p.760) The prevalence of CH has been reported to be between 0.4 and 20 % of the headache population [2, 3], and as high as 53 % in patients with headache after whiplash injury [4]. The dominant features of CH usually include: unilaterality of head pain without side-shift, elicitation of pain with external pressure over the ipsilateral upper neck, limited cervical range of motion, and the triggering of attacks by various awkward or sustained neck movements [4, 5].

 

Individuals with CH are frequently treated with spinal manipulative therapy including both mobilization and manipulation [6]. Spinal mobilization consists of slow, rhythmical, oscillating techniques whereas manipulation consists of high-velocity low-amplitude thrust techniques. [7] In a recent systematic review, Bronfort and colleagues reported that spinal manipulative therapy (both mobilization and manipulation) were effective in the management of adults with CH [8]. However, they did not report if manipulation resulted in superior outcomes compared to mobilization for the management of this population.

 

Several studies have investigated the effect of spinal manipulation in the management of CH [9�13]. Haas et al. [10] investigated the effectiveness of cervical manipulation in subjects with CH. Jull et al. [11] demonstrated treatment efficacy for manipulative therapy and/or exercise in the management of CH. However the manipulative therapy group included manipulation and mobilization therefore it cannot be determined if the beneficial effect was a result of the manipulation, mobilization or the combination.

 

A few studies have examined the benefits of manipulation versus mobilization for the management of mechanical neck pain with or without exercise [14�16]. However, no studies have directly compared the effects of manipulation versus mobilization and exercise in patients with CH. Considering the purported risks of manipulation [17], it is essential to determine if manipulation results in improved outcomes compared to mobilization for the management of patients with CH. Therefore, the purpose of this randomized clinical trial was to compare the effects of manipulation versus mobilization and exercise in patients with CH. We hypothesized that patients receiving manipulation over a 4-week treatment period would experience greater reductions in headache intensity, headache frequency, headache duration, disability, and medication intake at a 3-month follow-up than patients receiving cervical and thoracic mobilization combined with exercise.

 

Methods

 

Participants

 

In this multi-center randomized clinical trial, consecutive patients with CH presenting to 1 of 8 outpatient physical therapy clinics from a variety of geographical locations (Arizona, Georgia, New York, Ohio, Pennsylvania, South Carolina) were recruited over a 29-month period (from April 2012 to August 2014). For patients to be eligible, they had to present with a diagnosis of CH according to the revised diagnostic criteria [5] developed by the Cervicogenic Headache International Study Group (CHISG) [5, 18, 19]. CH was classified according to the �major criteria� (not including confirmatory evidence by diagnostic anesthetic blockades) and �head pain characteristics� of the CHISG. Therefore, in order to be included in the study, patients had to exhibit all of the following criteria: (1) unilaterality of the head pain without sideshift, starting in the upper posterior neck or occipital region, eventually spreading to the oculofrontotemporal area on the symptomatic side, (2) pain triggered by neck movement and/or sustained awkward positions, (3) reduced range of motion in the cervical spine [20] (i.e., less than or equal to 32 � of right or left passive rotation on the Flexion-Rotation Test [21�23], (4) pain elicited by external pressure over at least one of the upper cervical joints (C0-3), and (5) moderate to severe, non-throbbing and non-lancinating pain. In addition, participants had to have a headache frequency of at least 1 per week for a minimum of 3 months, a minimum headache intensity pain score of two points (0�10 on the NPRS scale), a minimum disability score of 20 % or greater (i.e., 10 points or greater on the 0�50 NDI scale), and be between 18 and 65 years of age.

 

Patients were excluded if they exhibited other primary headaches (i.e., migraine, TTH), suffered from bilateral headaches, or exhibited any red flags (i.e., tumor, fracture, metabolic diseases, rheumatoid arthritis, osteoporosis, resting blood pressure greater than 140/90 mmHg, prolonged history of steroid use, etc.), presented with two or more positive neurologic signs consistent with nerve root compression (muscle weakness involving a major muscle group of the upper extremity, diminished upper extremity deep tendon reflex, or diminished or absent sensation to pinprick in any upper extremity dermatome), presented with a diagnosis of cervical spinal stenosis, exhibited bilateral upper extremity symptoms, had evidence of central nervous system involvement (hyperreflexia, sensory disturbances in the hand, intrinsic muscle wasting of the hands, unsteadiness during walking, nystagmus, loss of visual acuity, impaired sensation of the face, altered taste, the presence of pathological reflexes), had a history of whiplash injury within the previous 6 weeks, had prior surgery to the head or neck, had received treatment for head or neck pain from any practitioner within the previous month, had received physical therapy or chiropractic treatment for head or neck pain within the previous 3 months, or had pending legal action regarding their head or neck pain.

 

The most recent literature suggests that pre-manipulative cervical artery testing is unable to identify those individuals at risk of vascular complications from cervical manipulation [24, 25], and any symptoms detected during pre-manipulative testing may be unrelated to changes in blood flow in the vertebral artery [26, 27]. Hence, pre-manipulative cervical artery testing was not performed in this study; however, screening questions for cervical artery disease had to be negative [24, 28, 29]. This study was approved by the Institutional Review Board at Long Island University, Brooklyn, NY. The study was registered at www.clinicaltrials.gov with trial identifier NCT01580280. All patients were informed that they would receive either manipulation or mobilization and exercise and then provided informed consent before their enrollment in the study.

 

Treating Therapists

 

Twelve physical therapists (mean age 36.6 years, SD 5.62) participated in the delivery of treatment for patients in this study. They had an average of 10.3 (SD 5.66, range 3�20 years) years of clinical experience, and all had completed a 60 h post-graduate certification program that included practical training in manual techniques including the use of cervical and thoracic manipulation. To ensure all examination, outcome assessments, and treatment procedures were standardized, all participating physical therapists were required to study a manual of standard operating procedures and participate in a 4 h training session with the principal investigator.

 

Examination Procedures

 

All patients provided demographic information, completed the Neck Pain Medical Screening Questionnaire, and completed a number of self-report measures, followed by a standardized history and physical examination at baseline. Self-report measures included headache intensity as measured by the NPRS (0�10), the NDI (0�50), headache frequency (number of days with headache in the last week), headache duration (total hours of headache in the last week), and medication intake (number of times the patient had taken narcotic or over-the-counter pain medication in the past week).

 

The standardized physical examination was not limited to, but included measurements of C1-2 (atlanto-axial joint) passive right and left rotation ROM using the Flexion-Rotation Test (FRT). The inter-rater reliability for the FRT has been found to be excellent (ICC: 0.93; 95 % CI: 0.87, 0.96) [30].

 

Outcome Measures

 

The primary outcome measure used in this study was the patient�s headache intensity as measured by the NPRS. Patients were asked to indicate the average intensity of headache pain over the past week using an 11-point scale ranging from 0 (�no pain�) to 10 (�worst pain imaginable�) at baseline, 1-week, 1-month, and 3-months following the initial treatment session [31]. The NPRS is a reliable and valid instrument to assess pain intensity [32�34]. Although no data exists in patients with CH, the MCID for the NPRS has been shown to be 1.3 in patients with mechanical neck pain [32] and 1.74 in patients with a variety of chronic pain conditions [34]. Therefore, we chose to only include patients with an NPRS score of 2 points (20 %) or greater.

 

Secondary outcome measures included the NDI, the Global Rating of Change (GRC), headache frequency, headache duration, and medication intake. The NDI is the most widely used instrument for assessing self-rated disability in patients with neck pain [35�37]. The NDI is a self-report questionnaire with 10-items rated from 0 (no disability) to five (complete disability) [38]. The numeric responses for each item are summed for a total score ranging between 0 and 50; however, some evaluators have chosen to multiply the raw score by two, and then report the NDI on a 0�100 % scale [36, 39]. Higher scores represent increased levels of disability. The NDI has been found to possess excellent test-retest reliability, strong construct validity, strong internal consistency and good responsiveness in assessing disability in patients with mechanical neck pain [36], cervical radiculopathy [33, 40], whiplash associated disorder [38, 41, 42], and mixed non-specific neck pain [43, 44]. Although no studies have examined the psychometric properties of the NDI in patients with CH, we chose to only include patients with an NDI score of ten points (20 %) or greater, because this cut-off score captures the MCID for the NDI, which has been reported to approximate four, eight, and nine points (0�50) in patients with mixed non-specific neck pain [44], mechanical neck pain [45], and cervical radiculopathy [33], respectively. Headache frequency was measured as the number of days with headache in the last week, ranging from 0 to 7 days. Headache duration was measured as the total hours of headache in the last week, with six possible ranges: (1) 0�5 h, (2) 6�10 h, (3) 11�15 h, (4) 16�20 h, (5) 21�25 h, or (6) 26 or more hours. Medication intake was measured as the number of times the patient had taken prescription or over-the-counter analgesic or anti-inflammatory medication in the past week for their headaches, with five options: (1) not at all, (2) once a week, (3) once every couple of days, (4) once or twice a day, or (5) three or more times a day.

 

Patients returned for 1-week, 4-weeks, and 3-months follow-ups where the aforementioned outcome measures were again collected. In addition, at the 1-week, 4-weeks and 3-months follow-ups, patients completed a 15-point GRC question based on a scale described by Jaeschke et al. [46] to rate their own perception of improved function. The scale ranges from -7 (a very great deal worse) to zero (about the same) to +7 (a very great deal better). Intermittent descriptors of worsening or improving are assigned values from -1 to -6 and +1 to +6, respectively. The MCID for the GRC has not been specifically reported but scores of +4 and +5 have typically been indicative of moderate changes in patient status [46]. However, it should be noted that recently Schmitt and Abbott reported that the GRC might not correlate with changes in function in a population with hip and ankle injuries [47]. All outcome measures were collected by an assessor blind to group assignment.

 

On the initial visit patients completed all outcome measures then received the first treatment session. Patients completed 6�8 treatment sessions of either manipulation or mobilization combined with exercise over 4 weeks. Additionally, subjects were asked if they had experienced any �major� adverse events [48, 49] (stroke or permanent neurological deficits) at each follow-up period.

 

Randomization

 

Following the baseline examination, patients were randomly assigned to receive either manipulation or mobilization and exercise. Concealed allocation was performed by using a computer-generated randomized table of numbers created by an individual not involved with recruiting patients prior to the beginning of the study. Individual, sequentially numbered index cards with the random assignment were prepared for each of 8 data collection sites. The index cards were folded and placed in sealed opaque envelopes. Blinded to the baseline examination, the treating therapist opened the envelope and proceeded with treatment according to the group assignment. Patients were instructed not to discuss the particular treatment procedure received with the examining therapist. The examining therapist remained blind to the patient�s treatment group assignment at all times; however, based on the nature of the interventions it was not possible to blind patients or treating therapists.

 

Manipulation Group

 

Manipulations targeting the right and left C1-2 articulations and bilateral T1-2 articulations were performed on at least one of the 6�8 treatment sessions (Figs. 1 and ?and2).2). On other treatment sessions, therapists either repeated the C1-2 and/or T1-2 manipulations or targeted other spinal articulations (i.e., C0-1, C2-3, C3-7, T2-9, ribs 1�9) using manipulation. The selection of the spinal segments to target was left to the discretion of the treating therapist and it was based on the combination of patient reports and manual examination. For both the upper cervical and upper thoracic manipulations, if no popping or cracking sound was heard on the first attempt, the therapist repositioned the patient and performed a second manipulation. A maximum of 2 attempts were performed on each patient similar to other studies [14, 50�53]. The clinicians were instructed that the manipulations are likely to be accompanied by multiple audible popping sounds [54�58]. Patients were encouraged to maintain usual activity within the limits of pain; however, mobilization and the prescription of exercises, or any use of other modalities, were not provided to this group.

The manipulation targeting C1-2 was performed with the patient in supine. For this technique, the patient�s left posterior arch of the atlas was contacted with the lateral aspect of the proximal phalanx of the therapist�s left second finger using a �cradle hold�. To localize the forces to the left C1-2 articulation, the patient was positioned using extension, a posterior-anterior (PA) shift, ipsilateral side-bend and contralateral side-shift. While maintaining this position, the therapist performed a single high-velocity, low-amplitude thrust manipulation to the left atlanto-axial joint using right rotation in an arc toward the underside eye and translation toward the table (Fig. 1). This was repeated using the same procedure but directed to the right C1-2 articulation.

 

The manipulation targeting T1-2 was performed with the patient in supine. For this technique, the patient held her/his arms and forearms across the chest with the elbows aligned in a superoinferior direction. The therapist contacted the transverse processes of the lower vertebrae of the target motion segment with the thenar eminence and middle phalanx of the third digit. The upper lever was localized to the target motion segment by adding rotation away and side-bend towards the therapist while the underside hand used pronation and radial deviation to achieve rotation toward and side-bend away moments, respectively. The space inferior to the xiphoid process and costochondral margin of the therapist was used as the contact point against the patient�s elbows to deliver a manipulation in an anterior to posterior direction targeting T1-2 bilaterally (Fig. 2).

 

Mobilization and Exercise Group

 

Mobilizations targeting the right and left C1-2 articulations and bilateral T1-2 articulations were performed on at least one of the 6�8 treatment sessions. On other treatment sessions, therapists either repeated the C1-2 and/or T1-2 mobilizations or targeted other spinal articulations (i.e., C0-1, C2/3, C3-7, T2-9, ribs 1�9) using mobilization. The selection of the spinal segments to target was left to the discretion of the treating therapist and it was based on the combination of patient reports and manual examination. However, in order to avoid a �contact� or �attention effect� when compared with the manipulation group, therapists were instructed to mobilize one cervical segment (i.e., right and left) and one thoracic segment or rib articulation on each treatment session.

 

The mobilization targeting the C1-2 articulation was performed in prone. For this technique, the therapist performed one 30 s bout of left-sided unilateral grade IV PA mobilizations to the C1-2 motion segment as described by Maitland [7]. This same procedure was repeated for one 30 s bout to the right atlanto-axial joint. In addition, and on at least one session, mobilization directed to the upper thoracic (T1-2) spine with the patient prone was performed. For this technique, the therapist performed one 30 s bout of central grade IV PA mobilizations to the T1-2 motion segment as described by Maitland [7]. Therefore, we used 180 (i.e., three 30 s bouts at approximately 2 Hz) end-range oscillations in total on each subject for the mobilization treatment. Notably, there is no high quality evidence to date to suggest that longer durations of mobilization result in greater pain reduction than shorter durations or dosages of mobilization [59, 60].

 

Cranio-cervical flexion exercises [11, 61�63] were performed with the patient in supine, with the knees bent and the position of the head standardized by placing the craniocervical and cervical spines in a mid-position, such that a line between the subject�s forehead and chin was horizontal, and a horizontal line from the tragus of the ear bisected the neck longitudinally. An air-filled pressure biofeedback unit (Chattanooga Group, Inc., Hixson, TN) was placed suboccipitally behind the patient�s neck and preinflated to a baseline of 20 mmHg [63]. For the staged exercises, patients were required to perform the craniocervical flexion action (�a nod of the head, similar to indicating yes�) [63] and attempt to visually target pressures of 22, 24, 26, 28, and 30 mmHg from a resting baseline of 20 mmHg and to hold the position steady for 10 s [61, 62]. The action of nodding was performed in a gentle and slow manner. A 10 s rest was allowed between trials. If the pressure deviated below the target pressure, the pressure was not held steady, substitution with the superficial flexors (sternocleidomastoid or anterior scalene) occurred, or neck retraction was noticed before the completion of the 10 s isometric hold, it was regarded as a failure [63]. The last successful target pressure was used to determine each patient�s exercise level wherein 3 sets of 10 repetitions with a 10 s isometric hold were performed. In addition to mobilizations and cranio-cervical flexion exercises, patients were required to perform 10 min of progressive resistance exercises (i.e., using Therabands� or free weights) to the muscles of the shoulder girdle during each treatment session, within their own tolerance, and specifically focusing on the lower trapezius and serratus anterior [11].

 

Sample Size

 

The sample size and power calculations were performed using online software from the MGH Biostatistics Center (Boston, MA). The calculations were based on detecting a 2-point (or 20 %) difference in the NPRS (headache intensity) at the 3 months follow-up, assuming a standard deviation of three points, a 2-tailed test, and an alpha level equal to 0.05. This generated a sample size of 49 patients per group. Allowing for a conservative dropout rate of 10 %, we planned to recruit at least 108 patients into the study. This sample size yielded greater than 90 % power to detect a statistically significant change in the NPRS scores.

 

Data Analysis

 

Descriptive statistics, including frequency counts for categorical variables and measures of central tendency and dispersion for continuous variables were calculated to summarize the data. The effects of treatment on headache intensity and disability were each examined with a 2-by-4 mixed-model analysis of variance (ANOVA), with treatment group (manipulation versus mobilization and exercise) as the between-subjects variable and time (baseline, 1 week, 4 weeks, and 3 months follow-up) as the within-subjects variable. Separate ANOVAs were performed with the NPRS (headache intensity) and NDI (disability) as the dependent variable. For each ANOVA, the hypothesis of interest was the 2-way interaction (group by time).

 

An independent t-test was used to determine the between group differences for the percentage change from baseline to 3-month follow-up in both headache intensity and disability. Separate Mann�Whitney U tests were performed with the headache frequency, GRC, headache duration and medication intake as the dependent variable. We performed Little�s Missing Completely at Random (MCAR) test [64] to determine if missing data points associated with dropouts were missing at random or missing for systematic reasons. Intention-to-treat analysis was performed by using Expectation-Maximization whereby missing data are computed using regression equations. Planned pairwise comparisons were performed examining the difference between baseline and follow-up periods between-groups using the Bonferroni correction at an alpha level of .05.

 

We dichotomized patients as responders at the 3-month follow-up using a cut score of 2 points improvement for headache intensity as measured by the NPRS. Numbers needed to treat (NNT) and 95 % confidence intervals (CI) were also calculated at the 3 months follow-up period using each of these definitions for a successful outcome. Data analysis was performed using SPSS 21.0.

 

Results

 

Two hundred and fifty-one patients with a primary complaint of headaches were screened for possible eligibility. The reasons for ineligibility can be found in Fig. 3, the flow diagram of patient recruitment and retention. Of the 251 patients screened, 110 patients, with a mean age of 35.16 years (SD 11.48) and a mean duration of symptoms of 4.56 years (SD 6.27), satisfied the eligibility criteria, agreed to participate, and were randomized into manipulation (n?=?58) and mobilization and exercise (n?=?52) groups. Baseline variables for each group can be found in Table 1. Twelve therapists from 8 outpatient physical therapy clinics each treated 25, 23, 20, 14, 13, 7, 6 or 2 patients, respectively; furthermore, each of the 12 therapists treated approximately an equal proportion of patients in each group. There was no significant difference (p?=?0.227) between the mean number of completed treatment sessions for the manipulation group (7.17, SD 0.96) and the mobilization and exercise group (6.90, SD 1.35). In addition, the mean number of treatment sessions that targeted the C1-2 articulation was 6.41 (SD 1.63) for the manipulation group and 6.52 (SD 2.01) for the mobilization and exercise group, and this was not significantly different (p?=?0.762). One hundred seven of the 110 patients completed all outcome measures through 3 months (97 % follow-up). Little�s Missing Completely at Random (MCAR) test was not statistically significant (p?=?0.281); therefore, we used the Expectation-Maximization imputation technique to replace missing values with predicted values for the missing 3-month outcomes.

The overall group by time interaction for the primary outcome of headache intensity was statistically significant for the NPRS (F(3,106)?=?11.196; p?<?0.001; partial eta squared?=?0.24). Between-group differences revealed that the manipulation group experienced statistically significant greater improvement in the NPRS at both the 1-week (2.1, 95 % CI: 1.2, 2.9), 4-week (2.3, 95 % CI: 1.5, 3.1) and 3-month (2.1, 95 % CI: 1.2, 3.0) follow-up periods (Table 2). In addition, an independent samples t-test revealed the between-group difference in percentage change in headache intensity (36.58 %, 95 % CI: 22.52, 50.64) from baseline to 3-month follow-up was statistically significant (t(108)?=?5.156; p?<?0.001) in favor of manipulation. See Table 3 for the percentage of subjects gaining 50, 75, and 100 % reduction in headache intensity at 3 months.

Table 3 Percentage of Subjects Gaining 50, 75, and 100 Percent Reduction | El Paso, TX Chiropractor

 

For secondary outcomes a significant group by time interaction existed for the NDI (F(3,106)?=?8.57; p?<?0.001; partial eta squared?=?0.20). At each follow-up period the manipulation group had superior outcomes in disability reduction as compared to the mobilization and exercise group. An independent samples t- test revealed the between-group mean percentage change in disability (35.56 %, 95 % CI: 24.95, 46.17) from baseline to 3 months follow-up was statistically significant (t(108)?=?6.646, p?<?0.001); indicating the manipulation group experienced a significantly greater percentage in disability reduction (Table 3).

 

Mann�Whitney U tests revealed that patients in the upper cervical and upper thoracic manipulation group experienced less frequent headaches at 1 week (p?<?0.001; median 2.0 versus 3.0), 4 weeks (p?<?0.001; median 1.0 versus 3.0) and 3 months (p?<?0.001; median 1.0 versus 2.5) than patients in the mobilization and exercise group. Headache duration was significantly lower at 1 week (p?=?0.005; median 2.0 versus 3.0, 4 weeks (p?<?0.001; median 1.0 versus 2.0) and 3 months (p?<?0.001; median 1.0 versus 2.0) in the manipulation group. Additionally, patient perceived improvement as measured by the GRC was significantly greater at 1 week (p?<?0.001, 4.0 versus 1.0), 4 weeks (p?<?0.001, 6.0 versus 3.0) and 3 months (p?<?0.001, 6.0 versus 3.0) than patients in the mobilization and exercise group. At 3 months, patients receiving upper cervical and upper thoracic manipulation experienced significantly (p?<?0.001) greater reductions in medication intake as compared to the mobilization and exercise group. Based on the cutoff score of 2 points on the NPRS, the NNT was 4.0 (95 % CI: 2.3, 7.7) in favor of the manipulation group at 3-month follow-up.

 

We did not collect any data on the occurrence of �minor� adverse events [48, 49] (transient neurological symptoms, increased stiffness, radiating pain, fatigue or other); however, no �major� adverse events [48, 49] (stroke or permanent neurological deficits) were reported for either group.

 

Discussion

 

Statement of Principal Findings

 

To our knowledge, this study is the first randomized clinical trial to directly compare the effectiveness of both cervical and thoracic manipulation to mobilization and exercise in patients with CH. The results suggest 6�8 sessions of manipulation over 4 weeks, directed mainly to both the upper cervical (C1-2) and upper thoracic (T1-2) spines, resulted in greater improvements in headache intensity, disability, headache frequency, headache duration, and medication intake than mobilization combined with exercises. The point estimates for between-group changes in headache intensity (2.1 points) and disability (6.0 points or 12.0 %) exceeded the reported MCIDs for both measures. Although the MCID for the NDI in patients with CH has not yet been investigated, it should however be noted that the lower bound estimate of the 95 % CI for disability (3.5 points) was slightly below (or approximated in two cases) the MCID that has been found to be 3.5 [65], 5 [66], and 7.5 [45] points in patients with mechanical neck pain, 8.5 [33] points in patients with cervical radiculopathy, and 3.5 [44] points in patients with mixed, non-specific neck pain. However, it should be recognized that both groups made clinical improvement. In addition, the NNT suggests for every four patients treated with manipulation, rather than mobilization, one additional patient achieves clinically important pain reduction at 3 months follow-up.

 

Strengths and Weaknesses of the Study

 

The inclusion of 12 treating physical therapists from 8 private clinics in 6 different geographical states enhances the overall generalizability of our findings. Although significant differences were recognized up to 3 months, it is not known if these benefits would have been sustained at long-term. In addition, we used high-velocity, low-amplitude manipulation techniques that employed bidirectional thrusts into rotation and translation simultaneously and Maitland based grade IV PA mobilization techniques; thus, we cannot be certain that these results are generalizable to other kinds of manual therapy techniques. Some might argue that the comparison group might have not received adequate intervention. We sought to balance internal and external validity so standardized treatment for both groups and provided a very explicit description of the techniques used which will also allow for replication. Furthermore, we did not measure minor adverse events and only asked about two potential major adverse events. Another limitation is that we included multiple secondary outcomes.

Jull et al. [11] demonstrated treatment efficacy for manipulative therapy and exercise in the management of CH; however, this treatment package included both mobilization and manipulation. The current study may provide evidence that the management of patients with CH should include some form of manipulation despite the fact it is often suggested that cervical manipulation should be avoided because of the risk of serious adverse events [67, 68]. Furthermore, it has been shown that individuals receiving spinal manipulation for neck pain and headaches are no more likely to experience a vertebrobasilar stroke than if they received treatment by their medical physician [69]. Additionally, after reviewing 134 case reports, Puentedura et al. concluded that with appropriate selection of patients by careful screening of red flags and contraindications, the majority of adverse events associated with cervical manipulation could have been prevented [70].

 

Meaning of the Study: Possible Explanations and Implications for Clinicians and Policymakers

 

Based on the results of the current study clinicians should consider incorporating spinal manipulation for individuals with CH. A recent systematic review found both mobilization and manipulation to be effective for the management of patients with CH but was unable to determine which technique was superior [8]. Additionally, clinical guidelines reported that manipulation, mobilization and exercise were all effective for the management of patients with CH; however, the guideline made no suggestions regarding the superiority of either technique. [71] The current results may assist authors of future systematic reviews and clinical guidelines in providing more specific recommendations about the use of spinal manipulation in this population.

 

Unanswered Questions and Future Research

 

The underlying mechanisms as to why manipulation may have resulted in greater improvements remains to be elucidated. It has been suggested that high-velocity displacement of vertebrae with impulse durations of less than 200 ms may alter afferent discharge rates [72] by stimulating mechanoreceptors and proprioceptors, thereby changing alpha motorneuron excitability levels and subsequent muscle activity [72�74]. Manipulation might also stimulate receptors in the deep paraspinal musculature, and mobilization might be more likely to facilitate receptors in the superficial muscles [75]. Biomechanical [76, 77], spinal or segmental [78, 79] and central descending inhibitory pain pathway [80�83] models are plausible explanations for the hypoalgesic effects observed following manipulation. Recently, the biomechanical effects of manipulation have been under scientific scrutiny [84], and it is plausible that the clinical benefits found in our study are associated with a neurophysiological response involving temporal sensory summation at the dorsal horn of the spinal cord [78]; however, this proposed model is currently supported only on findings from transient, experimentally induced pain in healthy subjects [85, 86], not patients with CH. Future studies should examine different manual therapy techniques with varying dosages and include a 1-year follow-up. Furthermore, future studies examining the neurophysiological effects of both manipulation and mobilization will be important for determining why there may or may not be a difference in clinical effects between these two treatments.

 

Conclusion

 

The results of the current study demonstrated that patients with CH who received cervical and thoracic manipulation experienced significantly greater reductions in headache intensity, disability, headache frequency, headache duration, and medication intake as compared to the group that received mobilization and exercise; furthermore, the effects were maintained at 3 months follow-up. Future studies should examine the effectiveness of different types and dosages of manipulation and include a long-term follow-up.

In conclusion,�head pain caused by secondary headache due to a health issue along the surrounding structures of the cervical spine, or neck, can cause painful and debilitating symptoms which can affect the patient’s quality of life. Spinal manipulation and mobilization can be safely and effectively utilized to help improve cervicogenic headache symptoms.

Additional Topics: Back Pain

 

According to statistics, approximately 80% of people will experience symptoms of back pain at least once throughout their lifetimes. Back pain is a common complaint which can result due to a variety of injuries and/or conditions. Often times, the natural degeneration of the spine with age can cause back pain. Herniated discs occur when the soft, gel-like center of an intervertebral disc pushes through a tear in its surrounding, outer ring of cartilage, compressing and irritating the nerve roots. Disc herniations most commonly occur along the lower back, or lumbar spine, but they may also occur along the cervical spine, or neck. The impingement of the nerves found in the low back due to injury and/or an aggravated condition can lead to symptoms of sciatica.

Chiropractic Headache Treatment Guidelines in El Paso, TX

Chiropractic Headache Treatment Guidelines in El Paso, TX

Headache pain is one of the most prevalent reasons for doctor office visits. The majority of people experience them at some point in their life and they can affect anyone, regardless of age, race and gender. The International Headache Society, or IHS, categorizes headaches as primary, when they are not caused by another injury and/or condition, or secondary, when there is an underlying cause behind them. From migraines to cluster headaches and tension headaches, people who suffer from constant head pain may find it difficult to participate in their everyday activities. Many healthcare professionals treat headache pain, however, chiropractic care has become a popular alternative treatment option for a variety of health issues. The purpose of the following article is to demonstrate evidence-based guidelines for the chiropractic treatment of adults with headache.

 

Evidence-Based Guidelines for the Chiropractic Treatment of Adults with Headache

 

Abstract

 

  • Objective: The purpose of this manuscript is to provide evidence-informed practice recommendations for the chiropractic treatment of headache in adults.
  • Methods: Systematic literature searches of controlled clinical trials published through August 2009 relevant to chiropractic practice were conducted using the databases MEDLINE; EMBASE; Allied and Complementary Medicine; the Cumulative Index to Nursing and Allied Health Literature; Manual, Alternative, and Natural Therapy Index System; Alt HealthWatch; Index to Chiropractic Literature; and the Cochrane Library. The number, quality, and consistency of findings were considered to assign an overall strength of evidence (strong, moderate, limited, or conflicting) and to formulate practice recommendations.
  • Results: Twenty-one articles met inclusion criteria and were used to develop recommendations. Evidence did not exceed a moderate level. For migraine, spinal manipulation and multimodal multidisciplinary interventions including massage are recommended for management of patients with episodic or chronic migraine. For tension-type headache, spinal manipulation cannot be recommended for the management of episodic tension-type headache. A recommendation cannot be made for or against the use of spinal manipulation for patients with chronic tension-type headache. Low-load craniocervical mobilization may be beneficial for longer term management of patients with episodic or chronic tension-type headaches. For cervicogenic headache, spinal manipulation is recommended. Joint mobilization or deep neck flexor exercises may improve symptoms. There is no consistently additive benefit of combining joint mobilization and deep neck flexor exercises for patients with cervicogenic headache. Adverse events were not addressed in most clinical trials; and if they were, there were none or they were minor.
  • Conclusions: Evidence suggests that chiropractic care, including spinal manipulation, improves migraine
    and cervicogenic headaches. The type, frequency, dosage, and duration of treatment(s) should be based on guideline recommendations, clinical experience, and findings. Evidence for the use of spinal manipulation as an isolated intervention for patients with tension-type headache remains equivocal. (J Manipulative Physiol Ther 2011;34:274-289)

Dr. Alex Jimenez’s Insight

Headache, or head pain, including migraine and other types of headaches, is one of the most common types of pain reported among the general population. These may occur on one or both sides of the head, can be isolated to a specific location or they may radiate across the head from one point. While headache symptoms can vary depending on the type of head pain as well as due to the source of the health issue, headaches are considered to be a general complaint regardless of their severity and form. Headache, or head pain, may occur as a result of spinal misalignment, or subluxation, along the length of the spine. Through the use of spinal adjustments and manual manipulations, chiropractic care can safely and effectively realign the spine, reducing stress and pressure on the surrounding structures of the spine, to ultimately help improve migraine headache pain symptoms as well as overall health and wellness.

 

Headache is a common experience in adults. Recurring headaches negatively impact family life, social activity, and work capacity.[1,2] Worldwide, according to the World Health Organization, migraine alone is 19th among all causes of years lived with disability. Headache is third among reasons for seeking chiropractic care in North America.[3]

 

Accurate diagnosis is key to management and treatment, and a wide range of headache types are described in the International Classification of Headache Disorders 2 (International Headache Society [IHS]).[4] The categories are intended for clinical as well as research use. The most common headaches, tension-type and migraine, are considered primary headaches that are episodic or chronic in nature. Episodic migraine or tension-type headaches occur fewer than 15 days per month, whereas chronic headaches occur more than 15 days per month for at least 3 (migraine) or 6 months (tension-type headache).[4] Secondary headaches are attributed to underlying clinical problems in the head or neck that may also be episodic or chronic. Cervicogenic headaches are secondary headaches commonly treated by chiropractors and involve pain referred from a source in the neck and perceived in 1 or more regions of the head. The IHS recognizes cervicogenic headache as a distinct disorder,[4] and evidence that headache can be attributed to a neck disorder or lesion based on history and clinical features (history of neck trauma, mechanical exacerbation of pain, reduced cervical range of motion, and focal neck tenderness, excluding myofascial pain alone) is relevant to diagnosis but is not without controversy in the literature.[4,5] When myofascial pain alone is the cause, the patient should be managed as having tension-type headaches.[4]

 

Treatment modalities typically used by chiropractors to care for patients with headaches include spinal manipulation, mobilization, device-assisted spinal manipulation, education about modifiable lifestyle factors, physical therapy modalities, heat/ice, massage, advanced soft tissue therapies such as trigger point therapy, and strengthening and stretching exercises. There is a growing expectation for health professions, including chiropractic, to adopt and use research-based knowledge, taking sufficient account of the quality of available research evidence to inform clinical practice. As a result, the purpose of the Canadian Chiropractic Association (CCA) and the Canadian Federation of Chiropractic Regulatory and Educational Accrediting Boards (Federation) Clinical Practice Guidelines Project is to develop guidelines for practice based on available evidence. The purpose of this manuscript is to provide evidence-informed practice recommendations for the chiropractic treatment of headache in adults.

 

Methods

 

The Guidelines Development Committee (GDC) planned for and adapted systematic processes for literature�searching, screening, review, analysis, and interpretation. Methods are consistent with criteria proposed by the �Appraisal of Guidelines Research and Evaluation� collaboration (www.agreecollaboration.org). This guideline is a supportive tool for practitioners. It is not intended as a standard of care. The guideline links available published evidence to clinical practice and is only 1 component of an evidence-informed approach to patient care.

 

Data Sources and Searches

 

Systematic search and evaluation of the treatment literature were conducted using methods recommended by The Cochrane Collaboration Back Review Group[6] and Oxman and Guyatt.[7] The search strategy was developed in MEDLINE by exploring MeSH terms related to chiropractic and specific interventions and later modified for other databases. The literature search strategy was intentionally broad. Chiropractic treatment was defined as including the most common therapies used by practitioners and was not restricted to treatment modalities delivered only by chiropractors. A wide net was cast to include treatments that may be administered in chiropractic care as well as those that could also be delivered in the context of care by other health care professionals in a specific research study (Appendix A). Spinal manipulation was defined as a high-velocity low-amplitude thrust delivered to the spine. Excluded therapies included invasive analgesic or neurostimulation procedures, pharmacotherapy, injections of botulinum toxin, cognitive or behavioral therapies, and acupuncture.

 

Literature searches were completed from April to May 2006, updated in 2007 (phase 1), and updated again in August 2009 (phase 2). Databases searched included MEDLINE; EMBASE; Allied and Complementary Medicine; the Cumulative Index to Nursing and Allied Health Literature; Manual, Alternative, and Natural Therapy Index System; Alt HealthWatch; Index to Chiropractic Literature; and the Cochrane Library (Appendix A). Searches included articles published in English or with English abstracts. The search strategy was limited to adults (?18 years); although research studies with subject inclusion criteria encompassing a broad range of ages, such as adults and adolescents, were retrieved using the search strategy. Reference lists provided in systematic reviews (SRs) were also reviewed by the GDC to minimize relevant articles from being missed.

 

Evidence Selection Criteria

 

Search results were screened electronically, and multi-stage screening was applied (Appendix B): stage 1A (title), 1B (abstract); stage 2A (full text), 2B (full text-methodology, relevance); and stage 3 (full text-final GDC screening as clinical content experts). Duplicate citations were removed, and relevant articles were retrieved as electronic�and/or hard copies for detailed analysis. Different assessors, using the same criteria, completed the literature screens in 2007 and 2009 due to the time span between searches.

 

Only controlled clinical trials (CCTs); randomized, controlled trials (RCTs); and systematic reviews (SRs) were selected as the evidence base for this guideline consistent with current standards for interpreting clinical findings. The GDC did not rate observational studies, case series, or case reports because of their uncontrolled nature and probable low methodological quality vs CCTs. This approach is consistent with updated methods for SRs published by the Cochrane Back Review Group.[8] If multiple SRs were published by the same authors on a given topic, only the most recent publication was counted and used for evidence synthesis. Systematic reviews of SRs were also excluded to avoid double counting of research results.

 

Literature Assessment and Interpretation

 

Quality ratings of CCTs or RCTs included 11 criteria answered by �yes (score 1)� or �no (score 0)/do not know (score 0)� (Table 1). The GDC documented 2 additional criteria of interest: (1) researchers’ use of IHS diagnostic criteria for subject enrollment and (2) evaluation of side effects (Table 1, columns L and M). Use of IHS criteria[4] was relevant to this Clinical Practice Guideline (CPG) process to confirm diagnostic specificity within and across research studies. Studies were excluded if IHS diagnostic criteria were not applied by the researchers for subject inclusion into a study (Appendix C); and if before 2004, before cervicogenic headache was included in the IHS classification, the diagnostic criteria of the Cervicogenic Headache International Study Group[9] were not used. Side effects were reviewed as a proxy for potential risk(s) with treatment. No weighting factor(s) was applied to individual criteria, and possible quality ratings ranged from 0 to 11. Both blinding of subjects and care providers were rated in the research articles by the GDC, since these items are listed in the quality rating tool.[6] The GDC’s methods did not adapt or alter the rating tool. The rationale for this approach was that certain treatment modalities (eg, transcutaneous electrical nerve stimulation [TENS], ultrasound) and trial designs may achieve patient and/or practitioner blinding.[10] The GDC did not limit the evaluation of these benchmarks of quality if indeed they were reported in clinical studies for the treatment of headache disorders. The GDC also considered it outside their scope of expertise to modify, without validation, a widely used rating tool used to assess the clinical literature.[6] New research tools for the analysis and rating of the manual therapy literature, however, are urgently needed and are noted as an area for future research in the discussion section below.

 

Table 1 Qualitative Ratings of Controlled Trials of Physical Treatments for the Management of Headache Disorders

 

Literature assessors were project contributors separate from the GDC and were unblinded as to study authors, institutions, and source journals. Three members of the GDC (MD, RR, and LS) corroborated quality rating methods by completing quality assessments on a random subset of 10 articles.[11-20] A high level of agreement was confirmed across quality ratings. Complete agreement on all items was achieved for 5 studies: in 10 of 11 items for 4 studies and 8 of 11 items for the 1 remaining study. All discrepancies were easily resolved through discussion and�consensus by the GDC (Table 1). Due to heterogeneity of research methods across trials, no meta-analysis or statistical pooling of trial results was done. Trials scoring more than half of the total possible rating (ie, ?6) were considered high quality. Trials scoring 0 through 5 were considered low quality. Studies with major methodological flaws or investigating specialized treatment techniques were excluded (eg, treatment not considered relevant by the GDC for the chiropractic care of patients with headache; Appendix Table 3).

 

Quality rating of SRs included 9 criteria answered by yes (score 1) or no (score 0)/do not know (score 0) and a qualitative response for item J �no flaws,� �minor flaws,� or �major flaws� (Table 2). Possible ratings ranged from 0 to 9. The determination of overall scientific quality of SRs with major flaws, minor flaws, or no flaws, as listed in column J (Table 2), was based on the literature raters’ answers to the previous 9 items. The following parameters were used to derive the overall scientific quality of a SR: if the no/do not know response was used, an SR was likely to have minor flaws at best. However, if �No� was used on items B, D, F, or H, the review was likely to have major flaws.[21] Systematic reviews scoring more than half of the total possible rating (ie, ?5) with no or minor flaws were rated as high quality. Systematic reviews scoring 4 or less and/or with major flaws were excluded.

 

Table 2 Qualitative Ratings of Systematic Reviews of Physical Treatments for the Management of Headache Disorders

 

Reviews were defined as systematic if they included an explicit and repeatable method for searching and analyzing the literature and if inclusion and exclusion criteria for studies were described. Methods, inclusion criteria, methods for rating study quality, characteristics of included studies, methods for synthesizing data, and results were evaluated. Raters achieved complete agreement for all rating items for 7 SRs[22-28] and for 7 of 9 items for the 2�additional SRs.[29,30] The discrepancies were deemed minor and easily resolved through GDC review and consensus (Table 2).

 

Developing Recommendations for Practice

 

The GDC interpreted the evidence relevant to chiropractic treatment of headache patients. A detailed summary of the relevant articles will be posted to the CCA/Federation Clinical Practice Guidelines Project web site.

 

Randomized, controlled trials and their findings were appraised to inform treatment recommendations. To assign an overall strength of evidence (strong, moderate, limited, conflicting, or no evidence),[6] the GDC considered the number, quality, and consistency of research results (Table 3). Strong evidence was considered only when multiple high-quality RCTs corroborated the findings of other researchers in other settings. Only high-quality SRs were appraised in relation to the body of evidence and to inform treatment recommendations. The GDC considered treatment modalities to have proven benefit(s) when supported by a minimum of moderate level of evidence.

Recommendations for practice were developed in collaborative working group meetings.

Literature

 

From the literature searches, initially 6206 citations were identified. Twenty-one articles met final criteria for inclusion and were considered in developing practice recommendations (16 CCTs/RCTs[11-20,31-36] and 5 SRs[24-27,29]). Quality ratings of the included articles are provided in Tables 1 and 2. Appendix Table 3 lists articles excluded in final screening by the GDC and reason(s) for their exclusion. Absence of subject and practitioner blinding and unsatisfactory descriptions of cointerventions were commonly identified methodological limitations of the controlled trials. Headache types evaluated in these trials included migraine (Table 4), tension-type headache (Table 5), and cervicogenic headache (Table 6). Consequently, only these headache types are represented by the evidence and practice recommendations in this CPG. Evidence summaries of SRs are provided in Table 7.

 

Practice Recommendations: Treatment of Migraine

 

  • Spinal manipulation is recommended for the management of patients with episodic or chronic migraine with or without aura. This recommendation is based on studies that used a treatment frequency 1 to 2 times per week for 8 weeks (evidence level, moderate). One high-quality RCT,[20] 1 low-quality RCT,[17] and 1 high- quality SR[24] support the use of spinal manipulation for patients with episodic or chronic migraine (Tables 4 and 7).
  • Weekly massage therapy is recommended for reducing episodic migraine frequency and for improving affective symptoms potentially linked to headache pain (evidence level, moderate). One high-quality RCT[16] supports this practice recommendation (Table 4). Researchers used a 45-minute massage with focus on neuromuscular and trigger point framework of the back, shoulder, neck, and head.
  • Multimodal multidisciplinary care (exercise, relaxation, stress and nutritional counseling, massage therapy) is recommended for the management of patients with episodic or chronic migraine. Refer as appropriate (evidence level, moderate). One high-quality RCT[32] supports the effectiveness of multi-modal multidisciplinary intervention for migraine (Table 4). The intervention prioritizes a general management approach consisting of exercise, education, lifestyle change, and self-management.
  • There are insufficient clinical data to recommend for or against the use of exercise alone or exercise combined with multimodal physical therapies for the management of patients with episodic or chronic migraine (aerobic exercise, cervical range of motion [cROM], or whole body stretching). Three low-quality CCTs[13,33,34] contribute to this conclusion (Table 4).

 

Practice Recommendations: Tension-Type Headache

 

  • Low-load craniocervical mobilization (eg, Thera-Band, Resistive Exercise Systems; Hygenic Corporation, Akron, OH) is recommended for longer term (eg, 6 months) management of patients with episodic or�chronic tension-type headaches (evidence level, moderate). One high-quality RCT[36] showed that low-load mobilization significantly reduced symptoms of tension-type headaches for patients during the longer term (Table 5).
  • Spinal manipulation cannot be recommended for the management of patients with episodic tension-type headache (evidence level, moderate). There is moderate-level evidence that spinal manipulation after premanipulative soft tissue therapy provides no additional benefit for patients with tension-type headaches. One high-quality RCT[12] (Table 5) and observations reported in 4 SRs[24-27] (Table 7) suggest no benefit of spinal manipulation for patients with episodic tension-type headaches.
  • A recommendation cannot be made for or against the use of spinal manipulation (2 times per week for 6 weeks) for patients with chronic tension-type headache. Authors of 1 RCT[11] rated as high quality by the quality assessment tool[6] (Table 1), and summaries of this study in 2 SRs[24,26] suggest that spinal manipulation may be effective for chronic tension-type headache. However, the GDC considers the RCT[11] difficult to interpret and inconclusive (Table 5). The trial is inadequately controlled with imbalances in the number of subject-clinician encounters between study groups (eg, 12 visits for subjects in the soft tissue therapy plus spinal manipulation group vs 2 visits for subjects in the amitriptyline group). There is no way of knowing whether a comparable level of personal attention for subjects in the amitriptyline group may have impacted the study outcomes. These considerations and interpretations from 2 other SRs[25,27]contribute to this conclusion (Table 7).
  • There is insufficient evidence to recommend for or against the use of manual traction, connective tissue manipulation, Cyriax’s mobilization, or exercise/ physical training for patients with episodic or chronic tension-type headache. Three low-quality inconclusive studies[19,31,35] (Table 5), 1 low-quality negative RCT,[14] and 1 SR[25] contribute to this conclusion (Table 7).

 

Practice Recommendations: Cervicogenic Headache

 

  • Spinal manipulation is recommended for the management of patients with cervicogenic headache. This recommendation is based on 1 study that used a treatment frequency of 2 times per week for 3 weeks (evidence level, moderate). In a high-quality RCT, Nilsson et al[18] (Table 6) showed a significantly positive effect of high-velocity, low-amplitude spinal manipulation for patients with cervicogenic headache. Evidence synthesis from 2 SRs[24,29] (Table 7) supports this practice recommendation.
  • Joint mobilization is recommended for the management of patients with cervicogenic headache (evidence level, moderate). Jull et al[15] examined the effects of Maitland joint mobilization 8 to 12 treatments for 6 weeks in a high-quality RCT (Table 6). Mobilization followed typical clinical practice, in which the choice of low-velocity and high-velocity techniques was based on initial and progressive assessments of patients’ cervical joint dysfunction. Beneficial effects were reported for headache frequency, intensity, as well as neck pain and disability. Evidence synthesis from 2 SRs[24,29] (Table 7) supports this practice recommendation.
  • Deep neck flexor exercises are recommended for the management of patients with cervicogenic headache (evidence level, moderate). This recommendation is based on a study of 2 times daily for 6 weeks. There is no consistently additive benefit of combining deep neck flexor exercises and joint mobilization for cervicogenic headache. One high-quality RCT[15] (Table 6) and observations provided in 2 SRs[24,29] (Table 7) support this practice recommendation.

 

Safety

 

Practitioners select treatment modalities in conjunction with all available clinical information for a given patient. Of the 16 CCTs/RCTS[11-20,31-36] included in the body of evidence for this CPG, only 6 studies[11,12,15,20,32,36] adequately assessed or discussed patient side effects or safety parameters (Table 1, column M). Overall, reported risks were low. Three of the trials reported safety information for spinal manipulation.[11,12,20] Boline et al[11] reported that 4.3% of subjects experienced neck stiffness after initial spinal manipulation that disappeared for all cases after the first 2 weeks of treatment. Soreness or increase in headaches after spinal manipulation (n = 2) were reasons for treatment discontinuation cited by Tuchin et al.[20] No side effects were experienced by any subjects studied by Bove et al[12] using spinal manipulation for the treatment of episodic tension-type headache. Treatment trials to evaluate efficacy outcomes may not enroll adequate numbers of subjects to assess the incidence of rare adverse events. Other research methods are required to�develop a full understanding of the balance between benefits and risks.

 

Discussion

 

Spinal manipulation and other manual therapies commonly used in chiropractic have been studied in several CCTs that are heterogeneous in subject enrollment, design, and overall quality. Patient and headache types systematically represented in the evidence base are migraine, tension-type headaches, and cervicogenic headache. The primary health status outcomes reported are typically headache frequency, intensity, duration, and quality-of-life measures. The evidence is no greater than a moderate level at this time.

 

The evidence supports the use of spinal manipulation for the chiropractic management of patients with migraine or cervicogenic headaches but not tension-type headaches. For migraine, multidisciplinary care using weekly 45-minute massage therapy and multimodal care (exercise, relaxation, and stress and nutritional counseling) may also be effective. Alternatively, joint mobilization or deep neck flexor exercises are recommended for improving symptoms of cervicogenic headache. There appears to be no consistently additive benefit of combining joint mobilization and deep neck flexor exercises for patients with cervicogenic headache. Moderate evidence support the use of low-load craniocervical mobilization for longer term management of tension-type headaches.

 

Limitations

 

Shortcomings for this guideline include the quantity and quality of supporting evidence found during the searches. No recent adequately controlled high-quality research studies with reproducible clinical findings have been published for the chiropractic care of headache patients. Studies are needed to further our understanding of specific manual therapies in isolation or in well-controlled combinations for the treatment of migraine, tension-type headache, cervicogenic headache, or other headache types presenting to clinicians (eg, cluster, posttraumatic head- ache). Another shortcoming of this literature synthesis is the reliance on published research studies with small sample sizes (Tables 4-6), short-term treatment paradigms, and follow-up periods. Well-designed clinical trials with sufficient numbers of subjects, longer term treatments, and follow-up periods need to be funded to advance chiropractic care, and spinal manipulation in particular, for the management of patients with headache disorders. As with any literature review and clinical practice guideline, foundational information and published literature are evolving. Studies that may have informed this work may have been published after the conclusion of this study.[37-39]

 

Considerations for Future Research

 

The GDC consensus is that there is a need for further chiropractic studies with patients with headache disorders.

 

  • More high-quality clinical research is needed. Future research requires study designs using active comparators and nontreatment and/or placebo group(s) to enhance the evidence base for patient care. Patient blinding to physical interventions to manage expectancy results is needed and has been explored by researchers in chiropractic for other pain conditions.[10] The lack of systematically reported studies presents a practical challenge for generating evidence-based treatment recommendations. All future studies should be structured using systematic validated methods (eg, Consolidated Standards of Reporting Trials [CONSORT] and Transparent Reporting of Evaluations with Non-randomized Designs [TREND]).
  • Systematic reporting of safety data is needed in chiropractic research. All clinical trials must collect and report on potential side effects or harms even if none are observed.
  • Develop novel quantitative tools for evaluating manual therapy research. Blinding serves to control expectancy effects and nonspecific effects of subject-provider interactions across study groups. It is typically not possible to blind subjects and providers in efficacy studies of manual therapies. Despite inherent limitations, both blinding of subjects and care providers were rated in the research articles by the GDC, since these items are included in high-quality rating instruments.[6] Advanced research tools for analyzing and subsequent rating of the manual therapy literature are urgently needed.
  • To advance research on functional outcomes in the chiropractic care of headache. This guideline identified that headache studies use a variable range of measures in evaluating the effect of treatment on health outcomes. Headache frequency, intensity, and duration are the most consistently used outcomes (Tables 4-6). Serious efforts are needed to include validated patient-centered outcome measures in chiropractic research that are congruent with improvements in daily living and resumption of meaningful routines.
  • Cost-effectiveness. No research studies were retrieved on cost-effectiveness of spinal manipulation for the treatment of headache disorders. Future clinical trials of spinal manipulation should evaluate cost-effectiveness.

 

Other research methods are required to develop a full understanding of the balance between benefits and risks. This CPG does not provide a review of all chiropractic treatments. Any omissions reflect gaps in the clinical literature. The type, frequency, dosage, and duration of treatment(s) should be based on guideline recommendations, clinical experience, and knowledge of the patient until higher levels of evidence are available.

 

Conclusions

 

There is a baseline of evidence to support chiropractic care, including spinal manipulation, for the management of migraine and cervicogenic headaches. The type, frequency, dosage, and duration of treatment(s) should be based on guideline recommendations, clinical experience, and knowledge of the patient. Evidence for the use of spinal manipulation as an isolated intervention for patients with tension-type headache remains equivocal. More research is needed.
Practice guidelines link the best available evidence to good clinical practice and are only 1 component of an evidence-informed approach to providing good care. This guideline is intended to be a resource for the delivery of chiropractic care for patients with headache. It is a �living document� and subject to revision with the emergence of new data. Furthermore, it is not a substitute for a practitioner’s clinical experience and expertise. This document is not intended to serve as a standard of care. Rather, the guideline attests to the commitment of the profession to advance evidence-based practice through engaging a knowledge exchange and transfer process to support the movement of research knowledge into practice.

 

Practical Applications

 

  • This guideline is a resource for the delivery of chiropractic care for patients with headache.
  • Spinal manipulation is recommended for the management of patients with migraine or cervicogenic headaches.
  • Multimodal multidisciplinary interventions including massage may benefit patients with migraine.
  • Joint mobilization or deep neck flexor exercises may improve symptoms of cervicogenic headache.
  • Low-load craniocervical mobilization may improve tension-type headaches.

In conclusion, headache is one of the most common reasons people seek medical attention. Although many healthcare professionals can treat headaches, chiropractic care is a well-known alternative treatment option frequently used to treat a variety of health issues, including several types of headaches. According to the article above, evidence suggests that chiropractic care, including spinal adjustments and manual manipulations, can improve headache and migraine.

Additional Topics: Back Pain

 

According to statistics, approximately 80% of people will experience symptoms of back pain at least once throughout their lifetimes. Back pain is a common complaint which can result due to a variety of injuries and/or conditions. Often times, the natural degeneration of the spine with age can cause back pain. Herniated discs occur when the soft, gel-like center of an intervertebral disc pushes through a tear in its surrounding, outer ring of cartilage, compressing and irritating the nerve roots. Disc herniations most commonly occur along the lower back, or lumbar spine, but they may also occur along the cervical spine, or neck. The impingement of the nerves found in the low back due to injury and/or an aggravated condition can lead to symptoms of sciatica.

Migraine Headache Pain Chiropractic Therapy in El Paso, TX

Migraine Headache Pain Chiropractic Therapy in El Paso, TX

Migraine headaches have been considered to be one of the most frustrating ailments when compared to other common health issues. Generally triggered by stress, the symptoms of migraines, including the debilitating head pain, sensitivity to light and sound as well as the nausea, can tremendously affect a migraineur’s quality of life. However, research studies have found that chiropractic care can help reduce the frequency and the severity of your migraine pain. Many healthcare professionals have demonstrated that a spinal misalignment, or subluxation, may be the source of migraine headache pain. The purpose of the article below is to demonstrate the outcome measures of chiropractic spinal manipulative therapy for migraine.

 

Chiropractic Spinal Manipulative Therapy for Migraine: a Three?Armed, Single?Blinded, Placebo, Randomized Controlled Trial

 

Abstract

 

  • Background and purpose: To investigate the efficacy of chiropractic spinal manipulative therapy (CSMT) for migraineurs.
  • Methods: This was a prospective three?armed, single?blinded, placebo, randomized controlled trial (RCT) of 17 months duration including 104 migraineurs with at least one migraine attack per month. The RCT was conducted at Akershus University Hospital, Oslo, Norway. Active treatment consisted of CSMT, whereas placebo was a sham push manoeuvre of the lateral edge of the scapula and/or the gluteal region. The control group continued their usual pharmacological management. The RCT consisted of a 1?month run?in, 3 months intervention and outcome measures at the end of the intervention and at 3, 6 and 12 months follow?up. The primary end?point was the number of migraine days per month, whereas secondary end?points were migraine duration, migraine intensity and headache index, and medicine consumption.
  • Results: Migraine days were significantly reduced within all three groups from baseline to post?treatment (P < 0.001). The effect continued in the CSMT and placebo group at all follow?up time points, whereas the control group returned to baseline. The reduction in migraine days was not significantly different between the groups (P > 0.025 for interaction). Migraine duration and headache index were reduced significantly more in the CSMT than the control group towards the end of follow?up (P = 0.02 and P = 0.04 for interaction, respectively). Adverse events were few, mild and transient. Blinding was strongly sustained throughout the RCT.
  • Conclusions: It is possible to conduct a manual?therapy RCT with concealed placebo. The effect of CSMT observed in our study is probably due to a placebo response.
  • Keywords: chiropractic, headache, migraine, randomized controlled trial, spinal manipulative therapy

Dr. Alex Jimenez’s Insight

Neck pain and headaches are the third most common reason people seek chiropractic care. Many research studies have demonstrated that chiropractic spinal manipulative therapy is a safe and effective alternative treatment option for migraines. Chiropractic care can carefully correct any spinal misalignment, or subluxation, found along the length of the spine, which has been shown to be a source for migraine headaches. In addition, spinal adjustments and manual manipulations can help reduce stress and muscle tension by decreasing the amount of pressure being placed against the complex structures of the spine as a result of a spinal misalignment, or subluxation. By realigning the spine as well as reducing stress and muscle tension, chiropractic care can improve migraine symptoms and decrease their frequency.

 

Introduction

 

The socio?economic costs of migraine are enormous due to its high prevalence and disability during attacks [1, 2, 3]. Acute pharmacological treatment is usually the first treatment option for migraine in adults. Migraineurs with frequent attacks, insufficient effect and/or contraindication to acute medication are potential candidates for prophylactic treatment. Migraine prophylactic treatment is often pharmacological, but manual therapy is not unusual, especially if pharmacological treatment fails or if the patient wishes to avoid medicine [4]. Research has suggested that spinal manipulative therapy may stimulate neural inhibitory systems at different spinal cord levels because it might activate various central descending inhibitory pathways [5, 6, 7, 8, 9, 10].

 

Pharmacological randomized controlled trials (RCTs) are usually double?blinded, but this is not possible in manual?therapy RCTs, as the interventional therapist cannot be blinded. At present there is no consensus on a sham procedure in manual?therapy RCTs that mimics placebo in pharmacological RCTs [11]. Lack of a proper sham procedure is a major limitation in all previous manual?therapy RCTs [12, 13]. Recently, we developed a sham chiropractic spinal manipulative therapy (CSMT) procedure, where participants with migraine were unable to distinguish between real and sham CSMT evaluated after each of 12 individual interventions over a 3?month period [14].

 

The first objective of this study was to conduct a manual?therapy three?armed, single?blinded, placebo RCT for migraineurs with a methodological standard similar to that of pharmacological RCTs.

 

The second objective was to assess the efficacy of CSMT versus sham manipulation (placebo) and CSMT versus controls, i.e. participants who continued their usual pharmacological management.

 

Methods

 

Study Design

 

The study was a three?armed, single?blinded, placebo RCT over 17 months. The RCT consisted of a 1?month baseline, 12 treatment sessions over 3 months with follow?up measures at the end of intervention, 3, 6 and 12 months later.

 

Participants were, before baseline, randomized equally into three groups: CSMT, placebo (sham manipulation) and control (continued their usual pharmacological management).

 

The design of the study conformed to the recommendations of the International Headache Society (IHS) and CONSORT (Appendix S1) [1, 15, 16]. The Norwegian Regional Committee for Medical Research Ethics and the Norwegian Social Science Data Services approved the project. The RCT was registered at ClinicalTrials.gov (ID no: NCT01741714). The full trial protocol has been published previously [17].

 

Participants

 

Participants were recruited from January to September 2013 primarily through the Department of Neurology, Akershus University Hospital. Some participants were also recruited through General Practitioners from Akershus and Oslo Counties or media advertisement. All participants received posted information about the project followed by a telephone interview.

 

Eligible participants were migraineurs of 18�70 years old with at least one migraine attack per month and were allowed to have concomitant tension?type headache but no other primary headaches. All participants were diagnosed by a chiropractor with experience in headache diagnostics during the interview and according to the International Classification of Headache Disorders?II (ICHD?II) 2. A neurologist had diagnosed all migraineurs from Akershus University Hospital.

 

Exclusion criteria were contraindication to spinal manipulative therapy, spinal radiculopathy, pregnancy, depression and CSMT within the previous 12 months. Participants who received manual therapy [18], changed their prophylactic migraine medicine or became pregnant during the RCT were informed that they would be withdrawn from the study at that time and regarded as drop?outs. Participants were allowed to continue and change acute migraine medication throughout the study period.

 

Eligible participants were invited to an interview and physical assessment including meticulous spinal column investigation by a chiropractor (A.C.). Participants randomized to the CSMT or the placebo group had a full spine radiographic examination.

 

Randomization and Masking

 

After written consent was obtained, participants were equally randomized into one of the three study arms by drawing one single lot. Numbered sealed lots with the three study arms were each subdivided into four subgroups by age and gender, i.e. 18�39 or 40�70 years, and men or women.

 

After each treatment session, the participants in the CSMT and the placebo group completed a questionnaire on whether they believed CSMT treatment was received, and how certain they were that active treatment was received on a 0�10 numeric rating scale, where 10 represented absolute certainty [14].

 

Both the block randomization and the blinding questionnaire were exclusively administered by a single external party.

 

Interventions

 

The CSMT group received spinal manipulative therapy using the Gonstead method, a specific contact, high?velocity, low?amplitude, short?lever spinal with no post?adjustment recoil that was directed to spinal biomechanical dysfunction (full spine approach) as diagnosed by standard chiropractic tests at each individual treatment session [19].

 

The placebo group received sham manipulation, a broad non?specific contact, low?velocity, low?amplitude sham push manoeuvre in a non?intentional and non?therapeutic directional line of the lateral edge of the scapula and/or the gluteal region [14]. All of the non?therapeutic contacts were performed outside the spinal column with adequate joint slack and without soft tissue pre?tension so that no joint cavitations occurred. The sham manipulation alternatives were pre?set and equally interchanged among the placebo participants according to protocol during the 12?week treatment period to strengthen the study validity. The placebo procedure is described in detail in the available trial protocol [17].

 

Each intervention session lasted for 15 min and both groups underwent the same structural and motion assessments prior to and after each intervention. No other intervention or advice was given to participants during the trial period. Both groups received interventions at Akershus University Hospital by a single experienced chiropractor (A.C.).

 

The control group continued their usual pharmacological management without receiving manual intervention by the clinical investigator.

 

Outcomes

 

The participants filled in a validated diagnostic headache diary throughout the study and returned them on a monthly basis [20]. In the case of unreturned diaries or missing data, the participants were contacted by phone to secure compliance.

 

The primary end?point was number of migraine days per month (30 days/month). At least 25% reduction of migraine days from baseline to end of intervention, with the same level maintained at 3, 6 and 12 months follow?up was expected in the CSMT group.

 

Secondary end?points were migraine duration, migraine intensity and headache index (HI), and medicine consumption. At least 25% reduction in duration, intensity and HI, and at least 50% reduction in medicine consumption were expected from baseline to end of intervention, with the same level maintained at 3, 6 and 12 months follow?up in the CSMT group.

 

No change was expected for primary and secondary end?point in the placebo and the control group.

 

A migraine day was defined as a day on which migraine with aura, migraine without aura or probable migraine occurred. Migraine attacks lasting for >24 h were calculated as one attack unless pain?free intervals of ?48 h had occurred [21]. If a patient fell asleep during a migraine attack and woke up without a migraine, in accordance with the ICHD?III ?, the duration of the attack was recorded as persisting until the time of awakening [22]. The minimum duration of a migraine attack was 4 h unless a triptan or drug containing ergotamine was used, in which case we specified no minimum duration. HI was calculated as mean migraine days per month (30 days) � mean migraine duration (h/day) � mean intensity (0�10 numeric rating scale).

 

The primary and secondary end?points were chosen based on the Task Force of the IHS Clinical Trial Subcommittee’s clinical trial guidelines [1, 15]. Based on previous reviews on migraine, a 25% reduction was considered to be a conservative estimate [12, 13].

 

The outcome analyses were calculated during the 30 days after the last intervention session and 30 days after the follow?up time points, i.e. 3, 6 and 12 months, respectively.

 

All adverse events (AEs) were recorded after each intervention in accordance with the recommendations of CONSORT and the IHS Task Force on AEs in migraine trials [16, 23].

 

Statistical Analysis

 

We based the power calculation on a recent study of topiramate in migraineurs [24]. We hypothesized the average difference in reduction of number of migraine days per month between the active and the placebo, and between the active and the control groups of 2.5 days, with SD of 2.5 for reduction in each group. As primary analysis includes two group comparisons, the significance level was set at 0.025. For the power of 80%, a sample size of 20 patients was required in each group to detect a significant difference in reduction of 2.5 days.

 

Patient characteristics at baseline were presented as means and SD or frequencies and percentages in each group and compared by independent samples t?test and ? 2 test.

 

Time profiles of all end?points were compared between the groups. Due to repeated measurements for each patient, linear mixed models accounting for the intra?individual variations were estimated for all end?points. Fixed effects for (non?linear) time, group allocation and interaction between the two were included. Random effects for patients and slopes were entered into the model. As the residuals were skewed, the bootstrap inference based on 1000 cluster samples was used. Pairwise comparisons were performed by deriving individual time point contrasts within each group at each time point with the corresponding P?values and 95% confidence intervals. Medicine consumption within groups was reported by mean doses with SD, and groups were compared by an independent samples median test. A dose was defined as a single administration of a triptan or ergotamine; paracetamol 1000 mg � codeine; non?steroidal anti?inflammatory drugs (tolfenamic acid, 200 mg; diclofenac, 50 mg; aspirin, 1000 mg; ibuprofen, 600 mg; naproxen, 500 mg); and morphinomimetics (tramadol, 50 mg). None of the patients changed study arm and none of the drop?outs filled in headache diaries after withdrawal from the study. Hence, only per protocol analysis was relevant.

 

The analyses were blinded to treatment allocation and conducted in SPSS v22 (IBM Corporation, Armonk, NY, USA) and STATA v14 (JSB) (StataCorp LP, College Station, TX, USA). A significance level of 0.025 was applied for the primary end?point, whereas elsewhere a level of 0.05 was used.

 

Ethics

 

Good clinical practice guidelines were followed [25]. Oral and written information about the project was provided in advance of inclusion and group allocation. Written consent was obtained from all participants. Participants in the placebo and control group were promised CSMT treatment after the RCT, if the active intervention was found to be effective. Insurance was provided through the Norwegian System of Compensation to Patients (Patient Injury Compensation), an independent national body that compensates patients injured by treatments provided by the Norwegian health service. A stopping rule was defined for withdrawing participants from this study in accordance with the recommendations in the CONSORT extension for Better Reporting of Harms [26]. All AEs were monitored during the intervention period and acted on as they occurred according to the recommendations of CONSORT and the IHS Task Force on AEs in migraine trials [16, 23]. In case of severe AE, the participant would be withdrawn from the study and referred to the General Practitioner or hospital emergency department depending on the event. The investigator (A.C.) was available by mobile phone at any time throughout the study treatment period.

Primary end?point. Migraine days were significantly reduced within all groups from baseline to post?treatment (P < 0.001). The effect continued in the CSMT and the placebo groups at 3, 6 and 12 months follow?up, whereas migraine days reverted to baseline level in the control group (Fig. ?2a). The linear mixed model showed no overall significant differences in change in migraine days between the CSMT and the placebo groups (P = 0.04) or between the CSMT and the control group (P = 0.06; Table 2). However, the pairwise comparisons at individual time points showed significant differences between the CSMT and the control group at all time points starting at post?treatment (Table 3).

 

Secondary end?points. There was a significant reduction from baseline to post?treatment in migraine duration, intensity and HI in the CSMT (P = 0.003, P = 0.002 and P < 0.001, respectively) and the placebo (P < 0.001, P = 0.001 and P < 0.001, respectively) groups, and the effect continued at 3, 6 and 12 months follow?up.

 

The only significant differences between the CSMT and control groups were change in migraine duration (P = 0.02) and in HI (P = 0.04; Table 2).

 

At 12 months follow?up, change in consumption of paracetamol was significantly lower in the CSMT group as compared with the placebo (P = 0.04) and control (P = 0.03) groups (Table 4).

 

Blinding. After each of the 12 intervention sessions, >80% of the participants believed they had received CSMT regardless of group allocation. The odds ratio for believing that CSMT treatment was received was >10 at all treatment sessions in both groups (all P < 0.001).

 

Adverse effects. A total of 703 of the potential 770 intervention sessions were assessed for AEs (355 in the CSMT group and 348 in the placebo group). Reasons for missed AE assessment were drop?out or missed intervention sessions. AEs were significantly more frequent in the CSMT than the placebo intervention sessions (83/355 vs. 32/348; P < 0.001). Local tenderness was the most common AE reported by 11.3% (95% CI, 8.4�15.0) in the CSMT group and 6.9% (95% CI, 4.7�10.1) in the placebo group, whereas tiredness on the intervention day and neck pain were reported by 8.5% and 2.0% (95% CI, 6.0�11.8 and 1.0�4.0), and 1.4% and 0.3% (95% CI, 0.6�3.3 and 0.1�1.9), respectively. All other AEs (lower back pain, face numbness, nausea, provoked migraine attack and fatigue in arms) were rare (<1%). No severe or serious AEs were reported.

 

Discussion

 

To our knowledge, this is the first manual?therapy RCT with a documented successful blinding. Our three?armed, single?blinded, placebo RCT evaluated the efficacy of CSMT in the treatment of migraine versus placebo (sham chiropractic) and control (usual pharmacological treatment). The results showed that migraine days were significantly reduced within all three groups from baseline to post?treatment. The effect continued in the CSMT and placebo groups at all follow?up time points, whereas the control group returned to baseline. AEs were mild and transient, which is in accordance with previous studies.

 

The study design adhered to the recommendations for pharmacological RCTs as given by the IHS and CONSORT [1, 15, 16]. Manual?therapy RCTs have three major obstacles as compared with pharmacological RCTs. Firstly, it is impossible to blind the investigator in relation to the applied treatment. Secondly, consensus on an inert placebo treatment is lacking [11]. Thirdly, previous attempts to include a placebo group have omitted validating the blinding, thus, it remains unknown whether active and placebo treatment were concealed [27]. Due to these challenges we decided to conduct a three?armed, single?blinded RCT, which also included a control group that continued usual pharmacological treatment in order to obtain an indication of the magnitude of the placebo response.

 

It has been suggested that, in pharmacological double?blind placebo RCTs, only 50% will believe that they receive active treatment in each group, if the blinding is perfect. However, this may not be true in manual?therapy RCTs, because the active and placebo physical stimulus might be more convincing than a tablet [28]. A single investigator reduces inter?investigator variability by providing similar information to all participants and it is generally recommended that the placebo intervention should resemble the active treatment in terms of procedure, treatment frequency and time spent with the investigator to allow for similar expectations in both groups [28]. The importance of our successful blinding is emphasized by the fact that all previous manual?therapy RCTs on headache lack placebo. Thus, we believe that our results discussed below are valid at the same level as a pharmacological RCT [14].

 

Prospective data are more reliable than retrospective data in terms of recall bias; however, non?compliance can be a challenge, especially at the end of the study. We believe the frequent contact between participants and the investigator, including monthly contact in the follow?up period, probably maintained high compliance throughout our study.

 

Although our study sample ended with 104 participants in the three groups, the power calculation assumption and the high completion rate support the data achieved being valid for the investigated population. The Gonstead method is used by 59% of chiropractors [19] and, thus, the results are generalizable for the profession. Diagnostic certainty is one of our major strengths as nearly all of the participants had been diagnosed by a neurologist according to the ICHD?II [2]. In contrast to previous chiropractic migraine RCTs that recruited participants through media such as newspapers and radio advertisement [12], the majority of our participants were recruited from the Department of Neurology, Akershus University Hospital, indicating that the migraineurs may have more frequent/severe attacks that are difficult to treat than the general population, as they were referred by their General Practitioner and/or practicing neurologist. Thus, our study is representative of primarily the tertiary clinic population, and the outcome might have been different if participants had been recruited from the general population. The percentage of neck pain has been found to be high in patients with migraine [29] and, thus, the high percentage of non?radicular spinal pain in our study might be a confounder for which effect was seen on migraine days.

 

Three pragmatic chiropractic manual?therapy RCTs using the diversified technique have previously been conducted for migraineurs [12, 30, 31, 32]. An Australian RCT showed within?group reduction in migraine frequency, duration and intensity of 40%, 43% and 36%, respectively, at 2 months follow?up [30]. An American study found migraine frequency and intensity to reduce within?group by 33% and 42%, respectively, at 1 month follow?up [31]. Another Australian study, which was the only RCT to include a control group, i.e. detuned ultrasound, found a within?group reduction of migraine frequency and duration of 35% and 40%, respectively, at 2 months follow?up in the CSMT group, as compared with a within?group reduction of 17% and 20% in the control group, respectively [32]. The reduction in migraine days was similar to ours (40%) in the CSMT group from baseline to 3 months follow?up, whereas migraine duration and intensity were less reduced at 3 months follow?up, i.e. 21% and 14%, respectively. Long?term follow?up comparisons are impossible as neither of the previous studies included a sufficient follow?up period. Our study design including strong internal validity allows us to interpret the effect seen as a placebo response.

 

Our RCT had fewer AEs as compared with previous manual?therapy studies, but of similar transient and mild character [33, 34, 35, 36, 37, 38, 39]. However, it was not sufficiently powered to detect uncommon serious AEs. In comparison, AEs in pharmacological migraine prophylactic placebo RCTs are common including non?mild and non?transient AEs [40, 41].

 

Conclusion

 

The blinding was strongly sustained throughout the RCT, AEs were few and mild, and the effect in the CSMT and placebo group was probably a placebo response. Because some migraineurs do not tolerate medication because of AEs or co?morbid disorders, CSMT might be considered in situations where other therapeutic options are ineffective or poorly tolerated.

According to statistics, approximately 80% of people will experience symptoms of back pain at least once throughout their lifetimes. Back pain is a common complaint which can result due to a variety of injuries and/or conditions. Often times, the natural degeneration of the spine with age can cause back pain. Herniated discs occur when the soft, gel-like center of an intervertebral disc pushes through a tear in its surrounding, outer ring of cartilage, compressing and irritating the nerve roots. Disc herniations most commonly occur along the lower back, or lumbar spine, but they may also occur along the cervical spine, or neck. The impingement of the nerves found in the low back due to injury and/or an aggravated condition can lead to symptoms of sciatica.

Psychology, Headache, Back Pain, Chronic Pain and Chiropractic in El Paso, TX

Everyone experiences pain from time to time. Pain is a physical feeling of discomfort caused by injury or illness. When you pull a muscle or cut your finger, for instance, a signal is sent through the nerve roots to the brain, signaling you that something is wrong in the body. Pain may be different for everyone and there are several ways of feeling and describing pain. After an injury or illness heals, the pain will subside, however, what happens if the pain continues even after you’ve healed?

 

Chronic pain is often defined as any pain which lasts more than 12 weeks. Chronic pain can range from mild to severe and it can be the result of previous injury or surgery, migraine and headache, arthritis, nerve damage, infection and fibromyalgia. Chronic pain can affect an individual’s emotional and mental disposition, making it more difficult to relieve the symptoms. Research studies have demonstrated that psychological interventions can assist the chronic pain recovery process. Several healthcare professionals, like a doctor of chiropractic, can provide chiropractic care together with psychological interventions to help restore the overall health and wellness of their patients. The purpose of the following article is to demonstrate the role of psychological interventions in the management of patients with chronic pain, including headache and back pain.

 

 

The Role of Psychological Interventions in the Management of Patients with Chronic Pain

 

Abstract

 

Chronic pain can be best understood from a biopsychosocial perspective through which pain is viewed as a complex, multifaceted experience emerging from the dynamic interplay of a patient�s physiological state, thoughts, emotions, behaviors, and sociocultural influences. A biopsychosocial perspective focuses on viewing chronic pain as an illness rather than disease, thus recognizing that it is a subjective experience and that treatment approaches are aimed at the management, rather than the cure, of chronic pain. Current psychological approaches to the management of chronic pain include interventions that aim to achieve increased self-management, behavioral change, and cognitive change rather than directly eliminate the locus of pain. Benefits of including psychological treatments in multidisciplinary approaches to the management of chronic pain include, but are not limited to, increased self-management of pain, improved pain-coping resources, reduced pain-related disability, and reduced emotional distress � improvements that are effected via a variety of effective self-regulatory, behavioral, and cognitive techniques. Through implementation of these changes, psychologists can effectively help patients feel more in command of their pain control and enable them to live as normal a life as possible despite pain. Moreover, the skills learned through psychological interventions empower and enable patients to become active participants in the management of their illness and instill valuable skills that patients can employ throughout their lives.

Dr. Alex Jimenez’s Insight

Chronic pain has previously been determined to affect the psychological health of those with persistent symptoms, ultimately altering their overall mental and emotional disposition. In addition, patients with overlapping conditions, including stress, anxiety and depression, can make treatment a challenge. The role of chiropractic care is to restore as well as maintain and improve the original alignment of the spine through the use of spinal adjustments and manual manipulations. Chiropractic care allows the body to naturally heal itself without the need for drugs/medications and surgical interventions, although these can be referred to by a chiropractor if needed. However, chiropractic care focuses on the body as a whole, rather than on a single injury and/or condition and its symptoms. Spinal adjustments and manual manipulations, among other treatment methods and techniques commonly used by a chiropractor, require awareness of the patient’s mental and emotional disposition in order to effectively provide them with overall health and wellness. Patients who visit my clinic with emotional distress from their chronic pain are often more susceptible to experience psychological issues as a result. Therefore, chiropractic care can be a fundamental psychological intervention for chronic pain management, along with those demonstrated below.

 

Introduction

 

Pain is a ubiquitous human experience. It is estimated that approximately 20%�35% of adults experience chronic pain.[1,2] The National Institute of Nursing Research reports that pain affects more Americans than diabetes, heart disease, and cancer combined.[3] Pain has been cited as the primary reason to seek medical care in the United States.[4] Furthermore, pain relievers are the second most commonly prescribed medications in physicians� offices and emergency rooms.[5] Further solidifying the importance of adequate assessment of pain, the Joint Commission on the Accreditation of Healthcare Organizations issued a mandate requiring that pain be evaluated as the fifth vital sign during medical visits.[6]

 

The International Association for the Study of Pain (IASP) defines pain as �an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage�.[7] The IASP�s definition highlights the multidimensional and subjective nature of pain, a complex experience that is unique to each individual. Chronic pain is typically differentiated from acute pain based on its chronicity or persistence, its physiological maintenance mechanisms, and/or its detrimental impact on an individual�s life. Generally, it is accepted that pain that persists beyond the expected period of time for tissue healing following an injury or surgery is considered chronic pain. However, the specific timeframe constituting an expected healing period is variable and often difficult to ascertain. For ease of classification, certain guidelines suggest that pain persisting beyond a 3�6 month time window is considered chronic pain.[7] Nevertheless, classification of pain based solely on duration is a strictly practical and, in some instances, arbitrary criterion. More commonly, additional factors such as etiology, pain intensity, and impact are considered alongside duration when classifying chronic pain. An alternative way to characterize chronic pain has been based on its physiological maintenance mechanism; that is, pain that is thought to emerge as a result of peripheral and central reorganization. Common chronic pain conditions include musculoskeletal disorders, neuropathic pain conditions, headache pain, cancer pain, and visceral pain. More broadly, pain conditions may be primarily nociceptive (producing mechanical or chemical pain), neuropathic (resulting from nerve damage), or central (resulting from dysfunction in the neurons of the central nervous system).[8]

 

Unfortunately, the experience of pain is frequently characterized by undue physical, psychological, social, and financial suffering. Chronic pain has been recognized as the leading cause of long-term disability in the working- age American population.[9] Because chronic pain affects the individual at multiple domains of his/her existence it also constitutes an enormous financial burden to our society. The combined direct and indirect costs of pain have been estimated to range from $125 billion to $215 billion, annually.[10,11] The widespread implications of chronic pain include increased reports of emotional distress (eg, depression, anxiety, and frustration), increased rates of pain-related disability, pain-related alterations in cognition, and reduced quality of life. Thus, chronic pain can be best understood from a biopsychosocial perspective through which pain is viewed as a complex, multifaceted experience emerging from the dynamic interplay of a patient�s physiological state, thoughts, emotions, behaviors, and sociocultural influences.

 

Pain Management

 

Given the widespread prevalence of pain and its multi-dimensional nature, an ideal pain management regimen will be comprehensive, integrative, and interdisciplinary. Current approaches to the management of chronic pain have increasingly transcended the reductionist and strictly surgical, physical, or pharmacological approach to treatment. Current approaches recognize the value of a multidisciplinary treatment framework that targets not only nociceptive aspects of pain but also cognitive-evaluative, and motivational-affective aspects alongside equally unpleasant and impacting sequelae. The interdisciplinary management of chronic pain typically includes multimodal treatments such as combinations of analgesics, physical therapy, behavioral therapy, and psychological therapy. The multimodal approach more adequately and comprehensively addresses pain management at the molecular, behavioral, cognitive-affective, and functional levels. These approaches have been shown to lead to superior and long-lasting subjective and objective outcomes including pain reports, mood, restoration of daily functioning, work status, and medication or health care use; multimodal approaches have also been shown to be more cost-effective than unimodal approaches.[12,13] The focus of this review will be specifically on elucidating the benefits of psychology in the management of chronic pain.

Patients will typically initially present to a physician�s office in the pursuit of a cure or treatment for their ailment/acute pain. For many patients, depending on the etiology and pathology of their pain alongside biopsychosocial influences on the pain experience, acute pain will resolve with the passage of time, or following treatments aimed at targeting the presumed cause of pain or its transmission. Nonetheless, some patients will not achieve resolution of their pain despite numerous medical and complementary interventions and will transition from an acute pain state to a state of chronic, intractable pain. For instance, research has demonstrated that approximately 30% of patients presenting to their primary-care physician for complaints related to acute back pain will continue to experience pain and, for many others, severe activity limitations and suffering 12 months later.[14] As pain and its consequences continue to develop and manifest in diverse aspects of life, chronic pain may become primarily a biopsychosocial problem, whereby numerous biopsychosocial aspects may serve to perpetuate and maintain pain, thus continuing to negatively impact the affected individual�s life. It is at this point that the original treatment regimen may diversify to include other therapeutic components, including psychological approaches to pain management.

 

Psychological approaches for the management of chronic pain initially gained popularity in the late 1960s with the emergence of Melzack and Wall�s �gate-control theory of pain�[15] and the subsequent �neuromatrix theory of pain�.[16] Briefly, these theories posit that psychosocial and physiological processes interact to affect perception, transmission, and evaluation of pain, and recognize the influence of these processes as maintenance factors involved in the states of chronic or prolonged pain. Namely, these theories served as integral catalysts for instituting change in the dominant and unimodal approach to the treatment of pain, one heavily dominated by strictly biological perspectives. Clinicians and patients alike gained an increasing recognition and appreciation for the complexity of pain processing and maintenance; consequently, the acceptance of and preference for multidimensional conceptualizations of pain were established. Currently, the biopsychosocial model of pain is, perhaps, the most widely accepted heuristic approach to understanding pain.[17] A biopsychosocial perspective focuses on viewing chronic pain as an illness rather than disease, thus recognizing that it is a subjective experience and that treatment approaches are aimed at the management, rather than the cure, of chronic pain.[17] As the utility of a broader and more comprehensive approach to the management of chronic pain has become evident, psychologically-based interventions have witnessed a remarkable rise in popularity and recognition as adjunct treatments. The types of psychological interventions employed as part of a multidisciplinary pain treatment program vary according to therapist orientation, pain etiology, and patient characteristics. Likewise, research on the effectiveness of psychologically based interventions for chronic pain has shown variable, albeit promising, results on key variables studied. This overview will briefly describe frequently employed psychologically based treatment options and their respective effectiveness on key outcomes.

 

Current psychological approaches to the management of chronic pain include interventions that aim to achieve increased self-management, behavioral change, and cognitive change rather than directly eliminate the locus of pain. As such, they target the frequently overlooked behavioral, emotional, and cognitive components of chronic pain and factors contributing to its maintenance. Informed by the framework offered by Hoffman et al[18] and Kerns et al,[19] the following frequently employed psychologically-based treatment domains are reviewed: psychophysiological techniques, behavioral approaches to treatment, cognitive behavioral therapy, and acceptance-based interventions.

 

Psychophysiological Techniques

 

Biofeedback

 

Biofeedback is a learning technique through which patients learn to interpret feedback (in the form of physiological data) regarding certain physiological functions. For instance, a patient may use biofeedback equipment to learn to recognize areas of tension in their body and subsequently learn to relax those areas to reduce muscular tension. Feedback is provided by a variety of measurement instruments that can yield information about brain electrical activity, blood pressure, blood flow, muscle tone, electrodermal activity, heart rate, and skin temperature, among other physiological functions in a rapid manner. The goal of biofeedback approaches is for the patient to learn how to initiate physiological self-regulatory processes by achieving voluntary control over certain physiological responses to ultimately increase physiological flexibility through greater awareness and specific training. Thus a patient will use specific self-regulatory skills in an attempt to reduce an undesired event (eg, pain) or maladaptive physiological reactions to an undesired event (eg, stress response). Many psychologists are trained in biofeedback techniques and provide these services as part of therapy. Biofeedback has been designated as an efficacious treatment for pain associated with headache and temporomandibular disorders (TMD).[20] A meta-analysis of 55 studies revealed that biofeedback interventions (including various biofeedback modalities) yielded significant improvements with regard to frequency of migraine attacks and perceptions of headache management self-efficacy when compared to control conditions.[21] Studies have provided empirical support for biofeedback for TMD, albeit more robust improvements with regard to pain and pain-related disability have been found for protocols that combine biofeedback with cognitive behavioral skills training, under the assumption that a combined treatment approach more comprehensively addresses the gamut of biopsychosocial problems that may be encountered as a result of TMD.[22]

 

Behavioral Approaches

 

Relaxation Training

 

It is generally accepted that stress is a key factor involved in the exacerbation and maintenance of chronic pain.[16,23] Stress can be predominantly of an environmental, physical, or psychological/emotional basis, though typically these mechanisms are intricately intertwined. The focus of relaxation training is to reduce tension levels (physical and mental) through activation of the parasympathetic nervous system and through attainment of greater awareness of physiological and psychological states, thereby achieving reductions in pain and increasing control over pain. Patients can be taught several relaxation techniques and practice them individually or in conjunction with one another, as well as adjuvant components to other behavioral and cognitive pain management techniques. The following are brief descriptions of relaxation techniques commonly taught by psychologists specializing in the management of chronic pain.

 

Diaphragmatic breathing. Diaphragmatic breathing is a basic relaxation technique whereby patients are instructed to use the muscles of their diaphragm as opposed to the muscles of their chest to engage in deep breathing exercises. Breathing by contracting the diaphragm allows the lungs to expand down (marked by expansion of abdomen during inhalation) and thus increase oxygen intake.[24]

 

Progressive muscle relaxation (PMR). PMR is characterized by engaging in a combination of muscle tension and relaxation exercises of specific muscles or muscle groups throughout the body.[25] The patient is typically instructed to engage in the tension/relaxation exercises in a sequential manner until all areas of the body have been addressed.

 

Autogenic training (AT). AT is a self-regulatory relaxation technique in which a patient repeats a phrase in conjunction with visualization to induce a state of relaxation.[26,27] This method combines passive concentration, visualization, and deep breathing techniques.

 

Visualization/Guided imagery. This technique encourages patients to use all of their senses in imagining a vivid, serene, and safe environment to achieve a sense of relaxation and distraction from their pain and pain-related thoughts and sensations.[27]

 

Collectively, relaxation techniques have generally been found to be beneficial in the management of a variety of types of acute and chronic pain conditions as well as in the management of important pain sequelae (eg, health-related quality of life).[28�31] Relaxation techniques are usually practiced in conjunction with other pain management modalities, and there is considerable overlap in the presumed mechanisms of relaxation and biofeedback, for instance.

 

Operant Behavior Therapy

 

Operant behavior therapy for chronic pain is guided by the original operant conditioning principles proposed by Skinner[32] and refined by Fordyce[33] to be applicable to pain management. The main tenets of the operant conditioning model as it relates to pain hold that pain behavior can eventually evolve into and be maintained as chronic pain manifestations as a result of positive or negative reinforcement of a given pain behavior as well as punishment of more adaptive, non-pain behavior. If reinforcement and the ensuing consequences occur with sufficient frequency, they can serve to condition the behavior, thus increasing the likelihood of repeating the behavior in the future. Therefore, conditioned behaviors occur as a product of learning of the consequences (actual or anticipated) of engaging in the given behavior. An example of a conditioned behavior is continued use of medication � a behavior that results from learning through repeated associations that taking medication is followed by removal of an aversive sensation (pain). Likewise, pain behaviors (eg, verbal expressions of pain, low activity levels) can be become conditioned behaviors that serve to perpetuate chronic pain and its sequelae. Treatments that are guided by operant behavior principles aim to extinguish maladaptive pain behaviors through the same learning principles that these may have been established by. In general, treatment components of operant behavior therapy include graded activation, time contingent medication schedules, and use of reinforcement principles to increase well behaviors and decrease maladaptive pain behaviors.

 

Graded activation. Psychologists can implement graded activity programs for chronic pain patients who have vastly reduced their activity levels (increasing likelihood of physical deconditioning) and subsequently experience high levels of pain upon engaging in activity. Patients are instructed to safely break the cycle of inactivity and deconditioning by engaging in activity in a controlled and time-limited fashion. In this manner, patients can gradually increase the length of time and intensity of activity to improve functioning. Psychologists can oversee progress and provide appropriate reinforcement for compliance, correction of misperceptions or misinterpretations of pain resulting from activity, where appropriate, and problem-solve barriers to adherence. This approach is frequently embedded within cognitive-behavioral pain management treatments.

 

Time-contingent medication schedules. A psychologist can be an important adjunct healthcare provider in overseeing the management of pain medications. In some cases, psychologists have the opportunity for more frequent and in-depth contact with patients than physicians and thus can serve as valuable collaborators of an integrated multidisciplinary treatment approach. Psychologists can institute time-contingent medication schedules to reduce the likelihood of dependence on pain medications for attaining adequate control over pain. Furthermore, psychologists are well equipped to engage patients in important conversations regarding the importance of proper adherence to medications and medical recommendations and problem-solve perceived barriers to safe adherence.

 

Fear-avoidance. The fear-avoidance model of chronic pain is a heuristic most frequently applied in the context of chronic low back pain (LBP).[34] This model draws largely from the operant behavior principles described previously. In essence, the fear-avoidance model posits that when acute pain states are repeatedly misinterpreted as danger signals or signs of serious injury, patients may be at risk of engaging in fear-driven avoidance behaviors and cognitions that further reinforce the belief that pain is a danger signal and perpetuate physical deconditioning. As the cycle continues, avoidance may generalize to broader types of activity and result in hypervigilance of physical sensations characterized by misinformed catastrophic interpretations of physical sensations. Research has shown that a high degree of pain catastrophizing is associated with maintenance of the cycle.[35] Treatments aimed at breaking the fear-avoidance cycle employ systematic graded exposure to feared activities to disconfirm the feared, often catastrophic, consequences of engaging in activities. Graded exposure is typically supplemented with psychoeducation about pain and cognitive restructuring elements that target maladaptive cognitions and expectations about activity and pain. Psychologists are in an excellent position to execute these types of interventions that closely mimic exposure treatments traditionally used in the treatment of some anxiety disorders.

 

Though specific graded exposure treatments have been shown to be effective in the treatment of complex regional pain syndrome type I (CRPS-1)[36] and LBP[37] in single-case designs, a larger-scale randomized controlled trial comparing systematic graded exposure treatment combined with multidisciplinary pain program treatment with multidisciplinary pain program treatment alone and with a wait-list control group found that the two active treatments resulted in significant improvements on outcome measures of pain intensity, fear of movement/injury, pain self-efficacy, depression, and activity level.[38] Results from this trial suggest that both interventions were associated with significant treatment effectiveness such that the graded exposure treatment did not appear to result in additional treatment gains.[38] A cautionary note in the interpretation of these results highlights that the randomized controlled trial (RCT) included a variety of chronic pain conditions that extended beyond LBP and CRPS-1 and did not exclusively include patients with high levels of pain-related fear; the interventions were also delivered in group formats rather than individual formats. Although in-vivo exposure treatments are superior at reducing pain catastrophizing and perceptions of harmfulness of activities, exposure treatments seem to be as effective as graded activity interventions in improving functional disability and chief complaints.[39] Another clinical trial compared the effectiveness of treatment-based classification (TBC) physical therapy alone to TBC augmented with graded activity or graded exposure for patients with acute and sub-acute LBP.[40] Outcomes revealed that there were no differences in 4-week and 6-month outcomes for reduction of disability, pain intensity, pain catastrophizing, and physical impairment among treatment groups, although graded exposure and TBC yielded larger reductions in fear-avoidance beliefs at 6 months.[40] Findings from this clinical trial suggest that enhancing TBC with graded activity or graded exposure does not lead to improved outcomes with regard to measures associated with the development of chronic LBP beyond improvements achieved with TBC alone.[40]

 

Cognitive-Behavioral Approaches

 

Cognitive-behavioral therapy (CBT) interventions for chronic pain utilize psychological principles to effect adaptive changes in the patient�s behaviors, cognitions or evaluations, and emotions. These interventions are generally comprised of basic psychoeducation about pain and the patient�s particular pain syndrome, several behavioral components, coping skills training, problem-solving approaches, and a cognitive restructuring component, though the exact treatment components vary according to the clinician. Behavioral components may include a variety of relaxation skills (as reviewed in the behavioral approaches section), activity pacing instructions/graded activation, behavioral activation strategies, and promotion of resumption of physical activity if there is a significant history of activity avoidance and subsequent deconditioning. The primary aim in coping skills training is to identify current maladaptive coping strategies (eg, catastrophizing, avoidance) that the patient is engaging in alongside their use of adaptive coping strategies (eg, use of positive self-statements, social support). As a cautionary note, the degree to which a strategy is adaptive or maladaptive and the perceived effectiveness of particular coping strategies varies from individual to individual.[41] Throughout treatment, problem-solving techniques are honed to aid patients in their adherence efforts and to help them increase their self-efficacy. Cognitive restructuring entails recognition of current maladaptive cognitions the patient is engaging in, challenging of the identified negative cognitions, and reformulation of thoughts to generate balanced, adaptive alternative thoughts. Through cognitive restructuring exercises, patients become increasingly adept at recognizing how their emotions, cognitions, and interpretations modulate their pain in positive and negative directions. As a result, it is presumed that the patients will attain a greater perception of control over their pain, be better able to manage their behavior and thoughts as they relate to pain, and be able to more adaptively evaluate the meaning they ascribe to their pain. Additional components sometimes included in a CBT intervention include social skills training, communication training, and broader approaches to stress management. Via a pain-oriented CBT intervention, many patients profit from improvements with regard to their emotional and functional well-being, and ultimately their global perceived health-related quality of life.

CBT interventions are delivered within a supportive and empathetic environment that strives to understand the patient�s pain from a biopsychosocial perspective and in an integrated manner. Therapists see their role as �teachers� or �coaches� and the message communicated to patients is that of learning to better manage their pain and improve their daily function and quality of life as opposed to aiming to cure or eradicate the pain. The overarching goal is to increase the patients� understanding of their pain and their efforts to manage pain and its sequelae in a safe and adaptive manner; therefore, teaching patients to self-monitor their behavior, thoughts, and emotions is an integral component of therapy and a useful strategy to enhance self-efficacy. Additionally, the therapist endeavors to foster an optimistic, realistic, and encouraging environment in which the patient can become increasingly skilled at recognizing and learning from their successes and learning from and improving upon unsuccessful attempts. In this manner, therapists and patients work together to identify patient successes, barriers to adherence, and to develop maintenance and relapse-prevention plans in a constructive, collaborative, and trustworthy atmosphere. An appealing feature of the cognitive behavioral approach is its endorsement of the patient as an active participant of his/her pain rehabilitation or management program.

 

Research has found CBT to be an effective treatment for chronic pain and its sequelae as marked by significant changes in various domains (ie, measures of pain experience, mood/affect, cognitive coping and appraisal, pain behavior and activity level, and social role function) when compared with wait-list control conditions.[42] When compared with other active treatments or control conditions, CBT has resulted in notable improvements, albeit smaller effects (effect size ~ 0.50), with regard to pain experience, cognitive coping and appraisal, and social role function.[42] A more recent meta-analysis of 52 published studies compared behavior therapy (BT) and CBT against treatment as usual control conditions and active control conditions at various time-points.[43] This meta-analysis concluded that their data did not lend support for BT beyond improvements in pain immediately following treatment when compared with treatment as usual control conditions.[43] With regard to CBT, they concluded that CBT has limited positive effects for pain disability, and mood; nonetheless, there are insufficient data available to investigate the specific influence of treatment content on selected outcomes.[43] Overall, it appears that CBT and BT are effective treatment approaches to improve mood; outcomes that remain robust at follow-up data points. However, as highlighted by several reviews and meta-analyses, a critical factor to consider in evaluating the effectiveness of CBT for the management of chronic pain is centered on issues of effective delivery, lack of uniform treatment components, differences in delivery across clinicians and treatment populations, and variability in outcome variables of interest across research trials.[13] Further complicating the interpretation of effectiveness findings are patient characteristics and additional variables that may independently affect treatment outcome.

 

Acceptance-Based Approaches

 

Acceptance-based approaches are frequently identified as third-wave cognitive-behavioral therapies. Acceptance and commitment therapy (ACT) is the most common of the acceptance-based psychotherapies. ACT emphasizes the importance of facilitating the client�s progress toward attaining a more valued and fulfilling life by increasing psychological flexibility rather than strictly focusing on restructuring cognitions.[44] In the context of chronic pain, ACT targets ineffective control strategies and experiential avoidance by fostering techniques that establish psychological flexibility. The six core processes of ACT include: acceptance, cognitive defusion, being present, self as context, values, and committed action.[45] Briefly, acceptance encourages chronic pain patients to actively embrace pain and its sequelae rather than attempt to change it, in doing so encouraging the patient to cease a futile fight directed at the eradication of their pain. Cognitive defusion (deliteralization) techniques are employed to modify the function of thoughts rather than to reduce their frequency or restructure their content. In this manner, cognitive defusion may simply alter the undesirable meaning or function of negative thoughts and thus decrease the attachment and subsequent emotional and behavioral response to such thoughts. The core process of being present emphasizes a non-judgmental interaction between the self and private thoughts and events. Values are utilized as guides for electing behaviors and interpretations that are characterized by those values an individual strives to instantiate in everyday life. Finally, through committed action, patients can realize behavior changes aligned with individual values. Thus, ACT utilizes the six core principles in conjunction with one another to take a holistic approach toward increasing psychological flexibility and decreasing suffering. Patients are encouraged to view pain as inevitable and accept it in a nonjudgmental manner so that they can continue to derive meaning from life despite the presence of pain. The interrelated core processes exemplify mindfulness and acceptance processes and commitment and behavior change processes.[45]

 

Results of research on the effectiveness of ACT-based approaches for the management of chronic pain are promising, albeit still warranting further evaluation. A RCT comparing ACT with a waitlist control condition reported significant improvements in pain catastrophizing, pain-related disability, life satisfaction, fear of movements, and psychological distress that were maintained at the 7 month follow-up.[46] A larger trial reported significant improvements for pain, depression, pain-related anxiety, disability, medical visits, work status, and physical performance.[47] A recent meta-analysis evaluating acceptance-based interventions (ACT and mindfulness-based stress reduction) in patients with chronic pain found that, in general, acceptance-based therapies lead to favorable outcomes for patients with chronic pain.[48] Specifically, the meta-analysis revealed small to medium effect sizes for pain intensity, depression, anxiety, physical wellbeing, and quality of life, with smaller effects found when controlled clinical trials were excluded and only RCTs were included in the analyses.[48] Other acceptance-based interventions include contextual cognitive-behavioral therapy and mindfulness-based cognitive therapy, though empirical research on the effectiveness of these therapies for the management of chronic pain is still in its infancy.

 

Expectations

 

An important and vastly overlooked common underlying element of all treatment approaches is consideration of the patient�s expectation for treatment success. Despite the numerous advances in the formulation and delivery of effective multidisciplinary treatments for chronic pain, relatively little emphasis has been placed on recognizing the importance of expectations for success and on focusing efforts on enhancement of patients� expectations. The recognition that placebo for pain is characterized by active properties leading to reliable, observable, and quantifiable changes with neurobiological underpinnings is currently at the vanguard of pain research. Numerous studies have confirmed that, when induced in a manner that optimizes expectations (via manipulation of explicit expectations and/or conditioning), analgesic placebos can result in observable and measurable changes in pain perception at a conscious self-reported level as well as a neurological pain-processing level.[49,50] Analgesic placebos have been broadly defined as simulated treatments or procedures that occur within a psychosocial context and exert effects on an individual�s experience and/or physiology.[51] The current conceptualization of placebo emphasizes the importance of the psychosocial context within which placebos are embedded. Underlying the psychosocial context and ritual of treatment are patients� expectations. Therefore, it is not surprising that the placebo effect is intricately embedded in virtually every treatment; as such, clinicians and patients alike will likely benefit from recognition that therein lies an additional avenue by which current treatment approaches to pain can be enhanced.

 

It has been proposed that outcome expectancies are core influences driving the positive changes attained through the various modes of relaxation training, hypnosis, exposure treatments, and many cognitive-oriented therapeutic approaches. Thus, a sensible approach to the management of chronic pain capitalizes on the power of patients� expectations for success. Regrettably, too often, health care providers neglect to directly address and emphasize the importance of patients� expectations as integral factors contributing to successful management of chronic pain. The zeitgeist in our society is that of mounting medicalization of ailments fueling the general expectation that pain (even chronic pain) ought to be eradicated through medical advancements. These all too commonly held expectations leave many patients disillusioned with current treatment outcomes and contribute to an incessant search for the �cure�. Finding the �cure� is the exception rather than the rule with respect to chronic pain conditions. In our current climate, where chronic pain afflicts millions of Americans annually, it is in our best interest to instill and continue to advocate a conceptual shift that instead focuses on effective management of chronic pain. A viable and promising route to achieving this is to make the most of patients� positive (realistic) expectations and educate pain patients as well as the lay public (20% of whom will at some future point become pain patients) on what constitutes realistic expectations regarding the management of pain. Perhaps, this can occur initially through current, evidence-based education regarding placebo and nonspecific treatment effects such that patients can correct misinformed beliefs they may have previously held. Subsequently clinicians can aim to enhance patients� expectations within treatment contexts (in a realistic fashion) and minimize pessimistic expectations that deter from treatment success, therefore, learning to enhance their current multidisciplinary treatments through efforts guided at capitalizing on the improvements placebo can yield, even within an �active treatment�. Psychologists can readily address these issues with their patients and help them become advocates of their own treatment success.

 

Emotional Concomitants of Pain

 

An often challenging aspect of the management of chronic pain is the unequivocally high prevalence of comorbid emotional distress. Research has demonstrated that depression and anxiety disorders are upward to three times more prevalent among chronic pain patients than among the general population.[52,53] Frequently, pain patients with psychiatric comorbidities are labeled �difficult patients� by healthcare providers, possibly diminishing the quality of care they will receive. Patients with depression have poorer outcomes for both depression and pain treatments, compared with patients with single diagnoses of pain or depression.[54,55] Psychologists are remarkably suited to address most of the psychiatric comorbidities typically encountered in chronic pain populations and thus improve pain treatment outcomes and decrease the emotional suffering of patients. Psychologists can address key symptoms (eg, anhedonia, low motivation, problem-solving barriers) of depression that readily interfere with treatment participation and emotional distress. Moreover, irrespective of a psychiatric comorbidity, psychologists can help chronic pain patients process important role transitions they may undergo (eg, loss of job, disability), interpersonal difficulties they may be encountering (eg, sense of isolation brought about by pain), and emotional suffering (eg, anxiety, anger, sadness, disappointment) implicated in their experience. Thus, psychologists can positively impact the treatment course by reducing the influence of emotional concomitants that are addressed as part of therapy.

 

Conclusion

 

Benefits of including psychological treatments in multidisciplinary approaches to the management of chronic pain are abundant. These include, but are not limited to, increased self-management of pain, improved pain-coping resources, reduced pain-related disability, and reduced emotional distress-improvements that are effected via a variety of effective self-regulatory, behavioral, and cognitive techniques. Through implementation of these changes, a psychologist can effectively help patients feel more in command of their pain control and enable them to live as normal a life as possible despite pain. Moreover, the skills learned through psychological interventions empower and enable patients to become active participants in the management of their illness and instill valuable skills that patients can employ throughout their lives. Additional benefits of an integrated and holistic approach to the management of chronic pain may include increased rates of return to work, reductions in health care costs, and increased health-related quality of life for millions of patients throughout the world.

Additional Topics: Back Pain

 

According to statistics, approximately 80% of people will experience symptoms of back pain at least once throughout their lifetimes. Back pain is a common complaint which can result due to a variety of injuries and/or conditions. Often times, the natural degeneration of the spine with age can cause back pain. Herniated discs occur when the soft, gel-like center of an intervertebral disc pushes through a tear in its surrounding, outer ring of cartilage, compressing and irritating the nerve roots. Disc herniations most commonly occur along the lower back, or lumbar spine, but they may also occur along the cervical spine, or neck. The impingement of the nerves found in the low back due to injury and/or an aggravated condition can lead to symptoms of sciatica.

Mindfulness Interventions for Chronic Headache in El Paso, TX

Mindfulness Interventions for Chronic Headache in El Paso, TX

If you’ve experienced a headache, you’re not alone. Approximately 9 out of 10 individuals in the United States suffer from headaches. While some are intermittent, some frequent, some are dull and throbbing, and some cause debilitating pain and nausea, getting rid of the head pain is an immediate response for many. But, how can you most effectively relieve a headache?

 

Research studies have demonstrated that chiropractic care is an effective alternative treatment option for many types of headaches. A 2014 report in the Journal of Manipulative and Physiological Therapeutics (JMPT) discovered that spinal adjustments and manual manipulations used in chiropractic care improved outcome measures for the treatment of chronic and acute neck pain as well as improved the benefits of a variety of treatment approaches for neck pain. Furthermore, a 2011 JMPT study found that chiropractic care can improve and reduce the frequency of migraine and cervicogenic headaches.

 

How Does Chiropractic Care Treat Headaches?

 

Chiropractic care focuses on the treatment of a variety of injuries and/or conditions of the musculoskeletal and nervous system, including headache. A chiropractor utilizes spinal adjustments and manual manipulations to carefully correct the alignment of the spine. A subluxation, or a spinal misalignment, has been demonstrated to cause symptoms, such as neck and back pain, and headache and migraine. A balanced spine can improve spine function as well as alleviate structural stress. In addition, a doctor of chiropractic can help treat headaches and other painful symptoms by supplying nutritional advice, offering posture and ergonomics advice and recommending stress management and exercise advice. Chiropractic care can ultimately ease muscle tension along the surrounding structures of the spine, restoring the spine’s original function.

Furthermore, chiropractic care can safely and effectively treat other spinal health issues, including symptoms of neck and lower back pain due to cervical and lumbar herniated discs, among other injuries and/or conditions. A chiropractor understands how a spinal misalignment, or subluxation, can affect different areas of the body and they will treat the body as a whole rather than focusing on the symptom alone. Chiropractic treatment can help the human body naturally restore its original health and wellness.

It is well-known that chiropractic care is effective for a variety of injuries and/or conditions, however, over the last few years, research studies have found that chiropractic can enhance our well-being by managing our stress. A number of these recent research studies demonstrated that chiropractic care can alter immune function, affect heart rate, and also reduce blood pressure. A 2011 research from Japan indicated that chiropractic may have a much bigger influence on your body than you believe.

 

Stress is an essential indicator of health, and chronic pain symptoms can tremendously affect wellness. Researchers in Japan sought to check whether chiropractic could alter stress levels in 12 men and women with neck pain and headache. But scientists at Japan wanted to find a more objective picture of how chiropractic spinal adjustments and manual manipulations affect the nervous system, so they used PET scans to monitor brain activity and salvia trials to monitor hormone changes.

 

After chiropractic care, patients had altered brain activity in the areas of the brain responsible for pain processing and stress reactions. They also had significantly reduced cortisol levels, indicating decreased stress. Participants also reported lower pain scores and a greater quality of life after treatment. Mindfulness interventions, such as chiropractic care, are fundamental stress management methods and techniques. Chronic stress can lead to a variety of health issues, including neck and back pain as well as headache and migraine. Other mindfulness interventions can also safely and effectively help improve symptoms. The purpose of the following article is to demonstrate the effectiveness of another mindfulness intervention, known as mindfulness-based stress reduction, on perceived pain intensity and quality of life in patients previously diagnosed with chronic headache.

 

The Effectiveness of Mindfulness-Based Stress Reduction on Perceived Pain Intensity and Quality of Life in Patients With Chronic Headache

 

Abstract

 

The aim of this study was to determine the effectiveness of Mindfulness-Based Stress reduction (MBSR) on perceived pain intensity and quality of life in patients with chronic headache. Thus, forty patients based on the diagnosis of a neurologist and diagnostic criteria of the International Headache Society (IHS) for migraine and chronic tension-type headache were selected and randomly assigned to the intervention group and control group, respectively. The participants completed the Pain and quality of life (SF-36) questionnaire. The intervention group enrolled in an eight-week MBSR program that incorporated meditation and daily home practice, per week, session of 90-minutes. Results of covariance analysis with the elimination of the pre-test showed significantly improvement of pain and quality of life in the intervention group compared with the control group. The findings from this study revealed that MBSR can be used non-pharmacological intervention for improvement the quality of life and development of strategies to cope with pain in patients with chronic headache. And can be used in combination with other therapies such as pharmacotherapy.

Dr. Alex Jimenez’s Insight

Chronic headache is a debilitating symptoms which affects many people. There are many different types of headaches, however, a majority of them often share a common trigger. Chronic stress can cause a variety of health issues of not properly managed, including muscle tension, which may lead to spinal misalignment, or subluxation, as well as other symptoms, such as neck and back pain, headaches and migraines. Stress management methods and techniques can ultimately help improve and manage stress associated symptoms. Mindfulness interventions like chiropractic care and mindfulness-based stress reduction have been determined to effectively help reduce stress and alleviate chronic headache symptoms.

 

Introduction

 

Headache is one of the most common complaints investigated in adult and pediatric neurological clinics. The vast majority of these headaches are migraine and tension-type headaches (Kurt & Kaplan, 2008). Headaches are classified into two categories of main or primary and secondary headaches. Ninety percent of headaches are primary headaches, among which migraine and tension headaches are the most common types (International Headache Society [IHS], 2013). According to the definition, migraine headache is usually unilateral and pulsating in nature and lasts from 4 to 72 hours. The associated symptoms include nausea, vomiting, increased sensitivity to light, sound and pain, and it generally increases with increasing physical activity. Also, tension headache is characterized by bilateral, non-pulsating pain, pressure or tightness, blunt pain, like a bandage or a hat, and a continuum of mild to moderate pain, preventing daily life activities (IHS, 2013).

 

Stovner et al. (2007) using the IHS diagnostic criteria, estimated the percentages of the adult population with an active headache disorder about 46% for headache in general, 42% for tension-type headache. This suggests that the incidence and the prevalence of tension-type headache are much higher than it was predicted. It is estimated that about 12 to 18 percent of the people have migraines (Stovner & Andree, 2010). Women are more likely to experience migraines compared to men, migraine prevalence is about 6% for men and 18% for women (Tozer et al., 2006).

 

Migraine and tension-type headaches are common and well-documented responses to psychological and physiological stressors (Menken, Munsat, & Toole, 2000). Migraine is a periodic and debilitating chronic pain and has a negative impact on quality of life, relationships and productivity. The World Health Organization (WHO) has announced the severe migraine as one of the most debilitating diseases with the nineteenth rank (IHS, 2013; Menken et al., 2000).

 

Despite the development of many medications for treatment and prevention of migraine attacks, a number of patients find them ineffective and some other find them inappropriate because of their side effects and side-effects often times lead to early discontinuation of treatment. As a result, a great interest in the development of non-pharmacologic treatments can be observed (Mulleners, Haan, Dekker, & Ferrari, 2010).

 

Biological factors alone cannot explain vulnerability to the experience of the headache, the onset of the attack and its course, intensified attacks of headache, headache-related disability and also the quality of life in patients with chronic headache. Negative life events are (as psychosocial factor) often known as a key factor in the development and exacerbation of headache (Nash & Thebarge, 2006).

 

The program of Mindfulness-Based Stress reduction (MBSR) is among the treatments, which have been studied in the past two decades on a variety of chronic pain. MBSR developed by Kabat-Zinn and used in a wide range of population with stress-related disorders and chronic pain (Kabat-Zinn, 1990). Especially in recent years, many studies have been conducted to examine the therapeutic effects of MBSR. Most studies have shown the significant effects of MBSR on different psychological conditions including the reduction of psychological symptoms of distress, anxiety, rumination, anxiety and depression (Bohlmeijer, Prenger, Taal, & Cuijpers, 2010; Carlson, Speca, Patel, & Goodey, 2003; Grossman, Niemann, Schmidt, & Walach, 2004; Jain et al., 2007; Kabat-Zinn, 1982; Kabat-Zinn, Lipworth, & Burney, 1985; Kabat-Zinn et al., 1992; Teasdale et al., 2002), pain (Flugel et al., 2010; Kabat-Zinn, 1982; Kabat-Zinn et al., 1985; La Cour & Petersen, 2015; Rosenzweig et al., 2010; Zeidan, Gordon, Merchant, & Goolkasian, 2010) and quality of life (Brown & Ryan, 2003; Carlson et al., 2003; Flugel et al., 2010; Kabat-Zinn, 1982; La Cour & Petersen, 2015; Morgan, Ransford, Morgan, Driban, & Wang, 2013; Rosenzweig et al., 2010).

 

Bohlmeijer et al. (2010) conducted a meta-analysis of eight randomized controlled studies on the effects of MBSR program, concluded that MBSR has small effects on depression, anxiety and psychological distress in people with chronic medical diseases. Also Grossman et al. (2004) in a meta-analysis of 20 controlled and uncontrolled studies on the effects of the MBSR program on physical and mental health of medical and non-medical samples, found an effect size of moderate for controlled studies on mental health. No effect sizes for specific symptoms such as depression and anxiety were reported. The most recent review includes 16 studies controlled and uncontrolled, This review reports that MBSR intervention decrease pain intensity, and most controlled trial studies (6 of 8) show higher reductions in pain intensity for intervention group compared with control group (Reiner, Tibi, & Lipsitz, 2013).

 

In another study, researchers found significant effect sizes for some subscales of quality of life for example vitality scale and bodily pain, nonsignificant effect sizes for pain and significant medium to large size effects for lower general anxiety and depression (La Cour & Petersen, 2015). Also in a study by Rosenzweig et al. (2010) on patients with chronic pain including those suffering from migraine, there were significant differences in pain intensity, pain-related functional limitations between patients. However, those suffering from migraine experienced the lowest improvement in pain and different aspects of quality of life. In general, different groups of chronic pain showed significant improvements in pain intensity and pain-related functional limitations in this study. Two other studies were conducted by Kabat-Zinn and using MBSR methods for treating patients with chronic pain, including a number of patients with chronic headaches. Statistical analysis showed a significant reduction in pain, pain interference with daily activities, medical and psychiatric signs and symptoms, anxiety and depression, negative body image, pain interference with daily activities, use of the drug and also increase in confidence (Kabat-Zinn, 1982; Kabat-Zinn et al., 1985).

 

Due to pain and loss of function and reduced work productivity and increased use of health care, chronic headache impose costs on individual and society, it seems that the chronic headache is a major health problem and finding ways to control and treat this problem could be of great importance. The main objective of this study was to evaluate the effectiveness of MBSR in addition to conventional pharmacotherapy in a clinical population sample of patients with chronic headache to show the effectiveness of this technique as a method of pain management and enhancement of the quality of life in patients with chronic headaches.

 

Methods

 

Participants and Procedure

 

This is a randomized controlled trial two- group �pretest-posttest� study design. Also an approval was obtained from the Ethics Committee of Zahedan University of Medical Sciences. The participants selected through convenience sampling method from patients with chronic migraine and tension-type headache, diagnosed by a neurologist and a psychiatrist using IHS diagnostic criteria-referred to university hospitals of Zahedan University of Medical Sciences, Zahedan-Iran.

 

After evaluating each patient for meeting the inclusion and exclusion criteria and taking an initial interview, 40 out of eighty-seven primary patients with chronic headache were selected and randomly assigned into two equal groups of intervention and control. Both the control and intervention groups received common pharmacotherapy under the supervision of the neurologist. During therapy sessions three subjects, due to the lack of a regular presence or exclusion criteria, opted out or were excluded from the study.

 

Inclusion Criteria

 

  • (1) Informed consent to participate in the sessions.
  • (2) Minimum age of 18 years.
  • (3) Minimum educational qualification of middle-school degree.
  • (4) The diagnosis of chronic headache (primary chronic migraine and tension-type headache) by the neurologist and according to IHS diagnostic criteria.
  • (5) 15 or more days per month for more than 3 months and least six months history of migraines and tension-type headache

 

Exclusion Criteria

 

  • (1) Subjects who were not willing to continue the participation in the study or leave the study for any reason.
  • (2) Other chronic pain problems.
  • (3) Psychosis, delirium and cognitive disorders.
  • (4) Cases of interpersonal difficulties interfering with teamwork.
  • (5) Drug and substance abuse.
  • (6) Mood disorder

 

Intervention Groups

 

Therapy sessions (MBSR) were held for 1.5 to 2 hours a week for the members of the intervention group (drug plus MBSR); While no MBSR was performed for the control group (only common drugs used) until the end of the research. The MBSR was carried out for 8 weeks. In this study, the 8-session MBSR program (Chaskalon, 2011) has been used. To do the meditation homework while training participants in sessions, the necessary measures have been provided in a CD and a booklet. If any one of subjects did not participate in a session or sessions, at the beginning of the next session the therapist would provide written notes of the sessions to the subjects, in addition to repeat the previous session summaries. MBSR program and discussions were presented to the patients in the eight sessions including: understanding pain and its aetiology, discuss about relationship stress, anger and emotion with pain, Understanding negative automatic thoughts, identyfying thoughts and feelings, introducing the concept of Acceptance, breathing space, three-minute breathing space, breath focus exercise, pleasant and unpleasant events daily, behavioral activation, mindfulness of routine activity, body scan practice, Seeing and hearing exercise, sitting meditation, mindful walking, reading poems related to mindfulness and also discuss how to keep up what has been developed over the whole course, discuss plans and positive reasons for maintaining the practice. Patients also received information about learning how to detect any future relapses as well as strategies and plans on which to base early detection of symptom pain attacks and for being self-directed towards new situations.

 

Control Group

 

Patients who were randomized in the control group were continuing usual pharmacotherapy(including specific and nonspecific drugs) by their neurologist until the end of the research.

 

Instruments

 

Two main tools were used in the pre-test and post-test to collect data, in addition to demographic data form. Headache log was used to determine the perceived intensity of pain using three parts: (1) 10-point likert-scale ratings, (2) the number of hours of pain per day and (3) pain frequency during the month. Each part is scored from 0 to 100, the highest level being 100. Since each patient rates their perceived pain intensity in the questionnaire, validity and reliability are not considered. And the other was a short-form 36 questionnaire (SF-36). The questionnaire is applicable in the various age groups and different diseases. The reliability and validity of the questionnaire was approved by Ware et al (Ware, Osinski, Dewey, & Gandek, 2000). The SF-36 assesses the perception of the quality of life in 8 subscales include: physical functioning (PF), role limitations due to physical health (RP), bodily pain (PB), general health (GH), energy and vitality (VT), social functioning (SF), role limitations due to emotional problems (RE) and affect health (AH). The tool has also two summary scales for Physical Component Summary (PCS) and Mental Component Summary (MCS) scores. Each scale is scored from 0 to 100, the highest functional status level being 100. The validity and reliability of the SF-36 were examined in an Iranian population. Internal consistency coefficients were between 0.70 and 0.85 for the 8 subscales and test-retest coefficients were between 0.49 and 0.79 with an interval of one week (Montazeri, Goshtasebi, Vahdaninia, & Gandek, 2005).

 

Data Analysis

 

For analyzing the data, in addition to the use of descriptive indicators, to compare the results of the intervention and control groups, the analysis of covariance was used to determine the effectiveness and the removal of the pre-test results at 95% confidence level.

 

Drop-Out

 

During therapy sessions three subjects, due to the lack of a regular presence or exclusion criteria, opted out or were excluded from the study. Thirty-seven out of 40 patients completed current study and the gathered data were then analyzed.

 

Results

 

Analysis for comparison of demographic distribution between the two groups was performed using chi-square and independent t-test. Demographic data of both groups are shown in Table 1. Distribution of age, educational years, gender and marital status were the same in each group.

Table 1: Demographic characteristics of participants.

 

Table 2 shows the results of analysis of covariance (ANCOVA). Levene�s test was non-significant, F (1, 35) = 2.78, P = 0.105, indicating that the assumption of homogeneity of variance had been approved. This finding shows that the variances across groups are equal and no difference was observed between two groups.

 

Table 2 The Results of Covarice Analysis

Table 2: The results of covariance analysis for the effectiveness of MBSR on pain intensity.

 

The main effect of MBSR intervention was significant, F (1, 34) = 30.68, P = 0.001, partial ?2 = 0.47, indicating that the pain intensity was lower after MBSR intervention (Mean = 53.89, SD.E = 2.40) than control group (Mean = 71.94, SD.E = 2.20). The covariate (pre-test of pain) was also significant, F (1, 34) = 73.41, P = 0.001, partial ?2 = 0.68, indicating that level of pain intensity before MBSR intervention had a significant effect on level of pain intensity. In other words, there was a positive relationship in the pain scores between pre-test and post-test. Therefore, the first research hypothesis is confirmed and MBSR treatment on perceived intensity was effective in patients with chronic headache and could reduce the intensity of perceived pain in these patients. All significant values are reported at p<0.05.

 

The second hypothesis of this study is the effectiveness of MBSR technique on quality of life in patients with chronic headache. To evaluate the effectiveness of MBSR technique on quality of life in patients with chronic headaches and eliminating the confounding variables and the effect of pre-test, for the analysis of data, multivariate covariance analysis (MANCOVA) of the dimensions of quality of life is used that Table 3 shows the results of analysis in the intervention group.

Table 3: The results of covariance analysis for the effectiveness of MBSR on quality of life.

 

The Table 3 shows the results of analysis of covariance (MANCOVA). The following information is needed to understand the results presented in Table 3.

 

The box�s test was non- significant, F = 1.08, P = 0.320, indicating that the variance�covariance matrices are the same in two groups and therefore the assumption of homogeneity is met. Also F (10, 16) = 3.153, P = 0.020, Wilks� Lambda = 0.33, partial ?2 = 0.66, indicating was a significant difference between the pre-test of the groups in the dependent variables.

 

Levene�s test was non-significant in some of dependent variables including [PF: F (1, 35) = 3.19, P = 0.083; RF: F (1, 35) = 1.92, P = 0.174; BP: F (1, 35) = 0.784, P = 0.382; GH: F (1, 35) = 0.659, P = 0.422; PCS: F (1, 35) = 2.371, P = 0.133; VT: F (1, 35) = 4.52, P = 0.141; AH: F (1, 35) = 1.03, P = 0.318], indicating that the assumption of homogeneity of variance had been approved in subscales of quality of life and Levene�s test was significant in some of dependent variables including [RE: F (1, 35) = 4.27, P = 0.046; SF: F (1, 35) = 4.82, P = 0.035; MCS: F (1, 35) = 11.69, P = 0.002], showing that the assumption of homogeneity of variance had been broken in subscales of quality of life.

 

The main effect of MBSR intervention was significant for some of dependent variables including [RP: F (1, 25) = 5.67, P = 0.025, partial ?2 = 0.18; BP: F (1, 25) = 12.62, P = 0.002, partial ?2 = 0.34; GH: F (1, 25) = 9.44, P = 0.005, partial ?2 = 0.28; PCS: F (1, 25) = 9.80, P = 0.004, partial ?2 = 0.28; VT: F (1, 25) = 12.60, P = 0.002, partial ?2 = 0.34; AH: F (1, 25) = 39.85, P = 0.001, partial ?2 = 0.61; MCS: F (1, 25) = 12.49, P = 0.002, partial ?2 = 0.33], these results indicating that subscales of RP, BP, GH, PCS, VT, AH, and MCS were higher after MBSR intervention [RP: Mean = 61.62, SD.E = 6.18; BP: Mean = 48.97, SD.E = 2.98; GH: Mean = 48.77, SD.E = 2.85; PCS: Mean = 58.52, SD.E = 2.72; VT: Mean = 44.99, SD.E = 2.81; AH: Mean = 52.60, SD.E = 1.97; MCS: Mean = 44.82, SD.E = 2.43] than control group [RP: Mean = 40.24, SD.E = 5.62; BP: Mean = 33.58, SD.E = 2.71; GH: Mean = 36.05, SD.E = 2.59; PCS: Mean = 46.13, SD.E = 2.48; VT: Mean = 30.50, SD.E = 2.56; AH: Mean = 34.49, SD.E = 1.80; MCS: Mean = 32.32, SD.E = 2.21].

 

Nonetheless, the main effect of MBSR intervention was non-significant for some of dependent variables including [PF: F (1, 25) = 1.05, P = 0.314, partial ?2 = 0.04; RE: F (1, 25) = 1.74, P = 0.199, partial ?2 = 0.06; SF: F (1, 25) = 2.35, P = 0.138, partial ?2 = 0.09]. These results indicating, although the means in these subscales of quality of life were higher [PF: Mean = 75.43, SD.E = 1.54; RE: Mean = 29.65, SD.E = 6.02; SF: Mean = 51.96, SD.E = 2.63] than the control group [PF: Mean = 73.43, SD.E = 1.40; RE: Mean = 18.08, SD.E = 5.48; SF: Mean = 46.09, SD.E = 2.40], But Mean difference was non-significant.

 

In summary, Covariance analysis (MANCOVA) results in Table 3 indicate a statistically significant difference in the scores of subscales of role limitation due to physical health (RP), bodily pain (BP), general health (GH), energy and vitality (VT), Affect health (AH) and sum of physical health dimensions (PCS) and mental health (MCS). And also indicates that there was not a statistically significant difference in subscale scores of physical functioning (PF), role limitations due to emotional problems (RE) and social functioning (SF) in the intervention group. All significant values are reported at p<0.05.

 

Discussion

 

This study aimed to evaluate the effectiveness of MBSR on perceived pain intensity and quality of life in patients with chronic headache. The results showed that MBSR treatment was significantly effective on reduction of pain intensity perception. The results of current study are consistent with the results of other researchers who had used the same method for chronic pain (e.g. Flugel et al., 2010; Kabat-Zinn, 1982; Kabat-Zinn et al., 1985; La Cour & Petersen, 2015; Reibel, Greeson, Brainard, & Rosenzweig, 2001; Reiner et al., 2013; Rosenzweig et al., 2010; zeidan et al., 2010). For example, in two studies conducted by Kabat-Zinn, where the MBSR program was used for treating patients with chronic pain by physicians, a number of patients with chronic headache were also included. The first study of the two studies, showed a significant reduction in pain, pain interference with daily activities, medical signs and psychiatric disorders, including anxiety and depression (Kabat-Zinn, 1982). The results of second study showed significant reduction in pain, negative body image, anxiety, depression, pain interference with daily activities, medical symptoms, medication use, and also showed an increase in self-confidence (Kabat-Zinn et al., 1985).

 

Also, the findings of the current study are consistent with the results of Rosenzweig et al. (2010), their results suggest that MBSR program is effective for reduction, physical pain, quality of life and psychological well-being of patients with various chronic pains and mindfulness is effective on emotional and sensory components of pain perception by self-regulation of attention through meditation activities. Although the results of Rosenzweig et al. (2010) showed that among patients with chronic pain the minimal impact on the reduction in bodily pain and improvement in quality of life was related to patients with fibromyalgia, chronic headache. In another study conducted by Flugel et al. (2010), although positive changes were observed in the frequency and the intensity of pain, the pain reduction was not statistically significant.

 

In another study, pain severity significantly reduced after the intervention in patients with tension headache. In addition, the MBSR group showed higher scores in mindful awareness in comparison with the control group (Omidi & Zargar, 2014). In a pilot study by Wells et al. (2014), their results showed that MBSR with pharmacological treatment was possible for patients with migraines. Although the small sample size of this pilot study did not provide power to detect a significant difference in the pain severity and migraine frequency, results demonstrated this intervention had a beneficial effect on headache duration, disability, self-efficacy.

 

In explaining the results of the effectiveness of mindfulness based therapies for pain it can be said, psychological models of chronic pain such as fear-avoidance model showed that the ways by which people interpret their feelings of pain and respond to them are important determinants in the experience of pain (Schutze, Rees, Preece, & Schutze, 2010). Pain catastrophizing is significantly associated with fear and anxiety caused by pain, the cognitive paths through which the fear of pain can be caused and also the pain-related disability is associated and also because the negative cognitive assessment of pain explains 7 to 31% of the variance of the pain intensity. Therefore, any mechanism that can reduce pain catastrophizing or make changes in its process can reduce the perception of pain intensity and the disability caused by that. Schutz et al. (2010) argue that the little mindfulness is the primer of pain catastrophizing. In fact, it seems that the tendency of the individual to engage in the automatic processing processes rather than knowledge-based processes with attention of insufficient flexibility, and lack of awareness of the present moment (Kabat-Zinn, 1990), will cause people to think more about the pain and thus overestimate the resulting risk of it. Thus, little mindfulness allows for the development of negative cognitive evaluation of the pain (Kabat-Zinn, 1990).

 

Another possible reason may be that the pain acceptance and readiness for change increase positive emotions, leading to a reduction in pain intensity through effects on the endocrine system and the production of endogenous opioids and reduction in pain-related disability or preparing individuals for the use of effective strategies to deal with pain (Kratz, Davis, & Zautra, 2007). Another possible reason to explain the results of the present study in its effectiveness on pain reduction can be the fact that chronic pain is developed due to an overactive stress response system (Chrousos & Gold, 1992). The result is the disturbing of the physical and mental processes. Mindfulness can allow for the access to the frontal cortex and improve it, brain areas that integrate physical and mental functions (Shapiro et al., 1995). The result is the creation of a little stimulation that reduces the intensity and the experience of physical and mental pain. Thus, pain impulses are experienced as feeling of the real pain rather than a negative recognition. The result is the closing of the pain channels that can reduce pain (Astin, 2004).

 

Mindfulness meditation Reduces Pain Through several Brain Mechanisms and various pathways such as changing of attention in meditation practices might impress both sensory and affective components of pain perception. On the other hand, mindfulness reduces the reactivity to distressing thoughts and feelings that accompany pain perception and strengthen the pain. Also, mindfulness reduces psychological symptoms such as comorbid anxiety and depression and increases parasympathetic activity, which can promote deep muscle relaxation that may reduce pain. Finally, mindfulness may decrease stress and mood dysfunction-related psychophysiologic activation by strengthening reframing negative situation and self-regulation skills. Higher level of mindfulness predicted lower levels of anxiety, depression, catastrophic thinking and disability. Other research has showed that mindfulness has an important role in cognitive and emotional control, and may be useful in reframing negative situations (Zeidan et al., 2011; Zeidan, Grant, Brown, McHaffie, & Coghill, 2012).

 

The second aim of this study was to determine the effectiveness of the MBSR program on quality of life in patients with chronic headache. This study showed that this treatment was significantly effective on quality of life dimensions, including role limitations due to health status, bodily pain, general health, energy and vitality, emotional health and overall physical and mental health scales. However, the MBSR program could not significantly increase the quality of life in physical functioning, role limitations due to emotional problems and social functioning. It seems apparent from previous and current studies and as well as from the present study that MBSR no effect on physical and social functions. This is likely because that the effects on pain levels in patients with headache are small, and that change is slow. On the other hand, patients with chronic pain have often learned to ignore pain in order to function normally (La Cour & Petersen, 2015). Although, the changes have been in the desired direction and increased the mean scores of the intervention group compared with the control group. These findings are consistent with previous findings (Brown & Ryan, 2003; Carlson et al., 2003; Flugel et al., 2010; Kabat-Zinn, 1982; La Cour & Petersen, 2015; Morgan et al., 2013; Reibel et al., 2001; Rosenzweig et al., 2010).

 

With regard to the content of the MBSR sessions, this program emphasizes the application of techniques to reduce stress, deal with pain and the awareness of the situation. Giving up the fight and accepting the present situation, without judgment, is the main concept of the program (Flugel et al., 2010). In fact, changes in acceptance without judgment are associated with improvement in quality of life (Rosenzweig et al., 2010). MBSR is aimed to increase awareness of the present moment. The treatment plan is a new and personal way to deal with stress to the individual. External stressors are part of life and cannot be changed, but coping skills and how to respond to the stress can be changed (Flugel et al., 2010). McCracken and velleman (2010) showed that cognitive flexibility and higher mindfulness is associated with less suffering and disability in patients. Patients with chronic pain with higher levels of mindfulness reported less depression, stress, anxiety and pain and also improvement in the self-efficacy and quality of life. Morgan et al. (2013) studying arthritis patients achieved similar results, so that patients with higher levels of mindfulness reported lower stress, depression and higher self-efficacy and quality of life. As noted above it was expected that pain reduction in patients leads to reduced fear and anxiety associated with pain and thereby reduces the resulting functioning limitations. Also, the results of the several studies (Cho, Heiby, McCracken, Lee, & Moon, 2010; McCracken, Gauntlett-Gilbert, & Vowles, 2007; Rosenzweig et al., 2010; Schutz et al., 2010) confirm this finding.

 

Several studies have been done to evaluate the effectiveness of different types of mindfulness-based treatments on chronic pain, including patients with headache. Unlike other research that examined heterogeneous sets of patients with chronic pain, the advantage of this study is that, it has been only performed on patients with chronic headache.

 

In the end, it should be acknowledged that there are some limitations in this study such as small sample size, lack of a long-term follow-up program, participants� medication use and arbitrary treatments; and despite the efforts of researchers, the lack of fully similar pharmacotherapy for all participants can confound the test results and make it difficult to generalize the results. Since the present study is the first of its type in patients with chronic headache in Iran, it is suggested that similar studies should be carry out in this field, with larger sample sizes as possible. And further studies investigate the stability of the treatment results in long-term follow-up periods of time.

 

Conclusion

 

According to the findings of this study it can be concluded that MBSR methods generally are effective on perceived pain intensity and quality of life of patients with chronic headache. Although there was no statistically significant difference in some aspects of quality of life, such as physical functioning, role limitations due to emotional problems and social functioning, but overall changes in mean were desired to the study. Thus the integrating of MBSR treatment with conventional medical therapy in the treatment protocol for patients with chronic headache can be advised. The researcher also believes that despite the shortcomings and deficiencies of current research, this study could be a new approach to the treatment of chronic headache and could provide a new horizon in this field of treatment.

In conclusion,�chiropractic care is a safe and effective alternative treatment option utilized to help improve as well as manage chronic headache symptoms by carefully and gently realigning the spine as well as providing stress management methods and techniques. Because stress has been associated with a variety of health issues, including subluxation, or misalignment of the spine, and chronic headache, mindfulness interventions like chiropractic care and mindfulness-based stress reduction (MBSR) are fundamental towards chronic headache. Finally, the article above demonstrated that MBSR can be effectively used as a mindfulness intervention for chronic headache and to improve overall health and wellness.

Additional Topics: Back Pain

 

According to statistics, approximately 80% of people will experience symptoms of back pain at least once throughout their lifetimes. Back pain is a common complaint which can result due to a variety of injuries and/or conditions. Often times, the natural degeneration of the spine with age can cause back pain. Herniated discs occur when the soft, gel-like center of an intervertebral disc pushes through a tear in its surrounding, outer ring of cartilage, compressing and irritating the nerve roots. Disc herniations most commonly occur along the lower back, or lumbar spine, but they may also occur along the cervical spine, or neck. The impingement of the nerves found in the low back due to injury and/or an aggravated condition can lead to symptoms of sciatica.

Mindfulness for Headache and Cervical Disc Herniation in El Paso, TX

Mindfulness for Headache and Cervical Disc Herniation in El Paso, TX

Stress is a result of the human body’s “fight or flight” response, a prehistoric defense mechanism triggered by the sympathetic nervous system (SNS). Stress is an essential component of survival. When stressors activate the fight or flight response, a mixture of chemicals and hormones are secreted into the blood flow, which prepare the body for perceived danger. Although short-term stress is helpful, however, long-term stress can lead to a variety of health issues. Furthermore, stressors in modern society have changed and it’s become more difficult for people to manage their stress and maintain mindfulness.

 

How Does Stress Affect the Body?

 

Stress can be experienced through three different channels: emotion; body and environment. Emotional stress involves adverse situations which affect our mind and decision making. Bodily stress includes improper nutrition and a lack of sleep. And finally, environmental stress occurs based on external experiences. When you experience any of these types of stressors, the sympathetic nervous system will trigger the “fight or flight” response, releasing adrenaline and cortisol to increase heart rate and heighten our senses to make us more alert in order to face the situation ahead of us.

 

However, if perceived stressors are always present, the SNS’s fight or flight response can remain active. Chronic stress can then lead to a variety of health issues, such as anxiety, depression, muscle tension, neck and back pain, digestive problems, weight gain and sleep problems as well as impaired memory and concentration. In addition, muscle tension along the spine due to stress can cause a spinal misalignment, or subluxation, which may in turn lead to disc herniation.

 

Headache and Disc Herniation from Stress

 

A herniated disc occurs when the soft, gel-like center of an intervertebral disc pushes through a tear in its outer, cartilage ring, irritating and compressing the spinal cord and/or the nerve roots. Disc herniation commonly occurs in the cervical spine, or neck, and in the lumbar spine, or low back. Symptoms of herniated discs depend on the location of the compression along the spine. Neck pain and back pain accompanied by numbness, tingling sensations and weakness along the upper and lower extremities are some of the most common symptoms associated with disc herniation. Headache and migraine are also common symptoms associated with stress and herniated discs along the cervical spine, as a result of muscle tension and spinal misalignment.

 

Mindfulness Interventions for Stress Management

 

Stress management is essential towards improving as well as maintaining overall health and wellness. According to research studies, mindfulness interventions, such as chiropractic care and mindfulness-based stress reduction (MBSR), among others, can safely and effectively help reduce stress. Chiropractic care utilizes spinal adjustments and manual manipulations to carefully restore the original alignment of the spine, relieving pain and discomfort as well as easing muscle tension. Additionally, a chiropractor may include lifestyle modifications to help further improve symptoms of stress.�A balanced spine can help the nervous system respond to stress more effectively. MBSR can also help reduce stress, anxiety and depression.

Effects of Mindfulness-Based Stress Reduction on Perceived Stress and Psychological Health in Patients with Tension Headache

 

Abstract

 

Background: Programs for improving health status of patients with illness related to pain, such as headache, are often still in their infancy. Mindfulness-based stress reduction (MBSR) is a new psychotherapy that appears to be effective in treating chronic pain and stress. This study evaluated efficacy of MBSR in treatment of perceived stress and mental health of client who has tension headache.

 

Materials and Methods: This study is a randomized clinical trial. Sixty patients with tension type headache according to the International Headache Classification Subcommittee were randomly assigned to the Treatment As Usual (TAU) group or experimental group (MBSR). The MBSR group received eight weekly classmates with 12-min sessions. The sessions were based on MBSR protocol. The Brief Symptom Inventory (BSI) and Perceived Stress Scale (PSS) were administered in the pre- and posttreatment period and at 3 months follow-up for both the groups.

 

Results: The mean of total score of the BSI (global severity index; GSI) in MBSR group was 1.63 � 0.56 before the intervention that was significantly reduced to 0.73 � 0.46 and 0.93 � 0.34 after the intervention and at the follow-up sessions, respectively (P < 0.001). In addition, the MBSR group showed lower scores in perceived stress in comparison with the control group at posttest evaluation. The mean of perceived stress before the intervention was 16.96 � 2.53 and was changed to 12.7 � 2.69 and 13.5 � 2.33 after the intervention and at the follow-up sessions, respectively (P < 0.001). On the other hand, the mean of GSI in the TAU group was 1.77 � 0.50 at pretest that was significantly reduced to 1.59 � 0.52 and 1.78 � 0.47 at posttest and follow-up, respectively (P < 0.001). Also, the mean of perceived stress in the TAU group at pretest was 15.9 � 2.86 and that was changed to 16.13 � 2.44 and 15.76 � 2.22 at posttest and follow-up, respectively (P < 0.001).

 

Conclusion: MBSR could reduce stress and improve general mental health in patients with tension headache.

Dr. Alex Jimenez’s Insight

Chiropractic care is an effective stress management treatment because it focuses on the spine, which is the base of the nervous system. Chiropractic utilizes spinal adjustments and manual manipulations to carefully restore the alignment of the spine in order to allow the body to naturally heal itself. A spinal misalignment, or subluxation, can create muscle tension along the spine and lead to a variety of health issues, including headache and migraine, as well as disc herniation and sciatica. Chiropractic care can also include lifestyle modifications, such as nutritional advice and exercise recommendations, to further enhance its effects. Mindfulness-based stress reduction can also effectively help with stress management and symptoms.

 

Introduction

 

Tension headache constitutes 90% of total headaches. About 3% of the population are suffering from chronic tension headache.[1] Tension headaches are often associated with lower quality of life and high levels of psychological discomforts.[2] In recent years, several meta-analyses evaluating the established pain treatments used today have shown that medical treatments, which may be effective in acute pain, are not effective with chronic pain and may, in fact, be causing further problems. Most of the pain treatments are designed for and useful for acute pain but if used in the long run may create more problems such as substance abuse and avoidance of important activities.[3] A common element in most of the pain treatments is that they emphasize on either avoiding pain or fighting to reduce pain. The pain in tension headache can be intolerable. Painkillers and pain management strategies can increase intolerance and sensitivity to pain. Therefore, the treatments that increase acceptance and tolerance to pain, especially chronic pain, are effective. Mindfulness-based stress reduction (MBSR) is a new psychotherapy that appears to be effective in improving physical performance and psychological well-being in patients with chronic pain.[4,5,6,7,8] In the past two decades, Kabat-Zinn et al. in the US successfully used mindfulness for the relief of pain and illness related to pain.[9] Recent studies on acceptance-based methods, such as mindfulness, show improved performance in patients with chronic pain. Mindfulness modulates the pain using nonelaborative awareness of thoughts, feelings and sensations, and an emotionally distanced relationship with internal and external experience.[10] Studies found that MBSR program can significantly alleviate medical illness related to chronic pains such as fibromyalgia, rheumatoid arthritis, chronic musculoskeletal pain, chronic low back pain, and multiple sclerosis.[7,11,12,13] MBSR has significant changes in pain intensity, anxiety, depression, somatic complaints, well-being, adaptation, quality of sleep, fatigue, and physical functioning.[6,14,15,16,17] But the programs for improving health status of patients with illness related to pain, such as tension headache, are often still in their infancy. Therefore, the study was conducted to assess the effects of MBSR on perceived stress and general mental health in patients with tension headache.

 

Materials and Methods

 

This randomized controlled clinical trial was performed in 2012 in Shahid Beheshti Hospital in Kashan City. The Research Ethics Committee of the Kashan University of Medical Sciences approved this study (IRCT No: 2014061618106N1). The participants of the study included adults with tension headache who were referred by the psychiatrists and neurologists in Kashan. The inclusion criteria were as follows: Having tension headache according to the International Headache Classification Subcommittee, willing to participate in the study, not having a medical diagnosis of organic brain disorder or psychotic disorder, and not having a history of psychological treatment during the preceding 6 months. The patients who did not complete the intervention and missed more than two sessions were excluded from the study. The participants, who signed an informed consent form, completed the measures as a pretest. For estimating the sample size, we referred to another study in which changes in mean of scores of fatigue was 62 � 9.5 in the pretreatment period and 54.5 � 11.5 in the posttreatment period.[18] Then, by utilizing the sample size calculation, 33 participants (with attrition risk) in each group with ? = 0.95 and 1 � ? = 0.9 were segregated. After sample size calculation, 66 patients with tension headache were selected via convenient sampling according to the inclusion criteria. Then, the patients were called and invited to participate in the study. If a patient agreed to participate, then he/she was invited to attend the study-briefing session and if not another patient was selected similarly. Then using a random number table, they were assigned either to the experimental group (MBSR) or to the control group that treated as usual. Finally, 3 patients were excluded from each group and 60 patients were included (30 patients in each group). The TAU group was treated only by antidepressant medication and clinical management. The MBSR group received MBSR training in addition to TAU. The patients in MBSR group were trained for 8 weeks by a clinical psychologist with PhD degree. The Brief Symptom Inventory (BSI) and Perceived Stress Scale (PSS) were administered before the first treatment session in the MBSR group, after the eighth session (posttest), and 3 months after the test (follow-up) in both groups. The TAU group was invited to Shahid Beheshti Hospital to fill out the questionnaires. Figure 1 shows a Consolidated Standards of Reporting Trials (CONSORT) diagram depicting the flow of study participants.

Intervention

 

The intervention group (MBSR) was trained in Shahid Beheshti Hospital. The eight weekly sessions (120 min) were held according to the standard MBSR protocol as developed by Kabat-Zinn.[11] Additional sessions were held for the participants who had missed one or two sessions. At the end of the training and 3 months later (follow-up), both MBSR and TAU groups were invited to Shahid Beheshti Hospital (the place of MBSR trial) and were instructed to complete the questionnaires. During the MBSR sessions, the participants were trained to be aware of their thoughts, feelings, and physical sensations nonjudgmentally. Mindfulness exercises are taught as two forms of meditation practices � formal and informal. Formal type exercises include trained sitting meditation, body scan, and mindful yoga. In informal meditation, attention and awareness are focused not only on daily activities, but also on thoughts, feelings, and physical sensation even they are problematic and painful. The overall content of the sessions were mentioned in Table 1.

Measurement Tools

 

International Headache Classification Subcommittee Diary Scale for Headache

 

Headache was measured by diary scale for headache.[19] The patients were asked to record the pain severity diary on a 0-10 rating scale. Absence of pain and the most intense disabling headache were characterized by 0 and 10, respectively. The mean of headache severity in a week was calculated by dividing the sum of the severity scores by 7. Moreover, the mean of headache severity in a month was calculated by dividing the sum of the severity scores by 30. The minimum and maximum scores of headache severity were 0 and 10, respectively. Headache diary was given to five patients and a neurologist and a psychiatrist confirmed the content validity of the instrument.[20] The reliability coefficient of Persian version of this scale was calculated as 0.88.[20]

 

Brief symptom Inventory (BSI)

 

Psychological symptoms were assessed with the BSI.[21] The inventory consist 53 items and 9 subscales that assess psychological symptoms. Each item scores between 0 and 4 (for example: I have nausea or upset in my stomach). BSI has a global severity index (GSI) achieved a total score of 53 items. The reliability of the test has reported a score of 0.89.[22] In our study, GSI test�retest estimate was .90 based on a sample of 60 patients with tension headache who completed the BSI.

 

Perceived Stress Scale (PSS)

 

Perceived stress was assessed using the PSS,[21,23] a 10-item scale that assesses the degree of uncontrollable and unpredictable situations of life during the past month (for example: Felt that you were unable to control the important things in your life?). Respondents report the prevalence of an item within the last month on a 5-point scale, ranging from 0 (never) to 4 (very often). Scoring is completed by reverse scoring of four positively worded items[4,5,7,8] and summing all item scores. The scale scores range from 0-40. Higher scores indicate higher levels of stress. It assumes that people depending on their coping resources evaluate level of threatening or challenging events. A higher score indicates a greater degree of perceived stress. Adequate test�retest reliability and convergent and discriminate validity have also been reported.[19] In our study, Cronbach’s alpha coefficients for assessing internal consistency of this scale were calculated to be 0.88.

 

The repeated measures analysis of variance was performed to compare the MBSR and TAU groups on measures of perceived stress and GSI at pretreatment, posttreatment, and 3-month follow-up. Also, Chi-square test was used to compare the demographics in the two groups. P value less than 0.05 was considered significant in all tests.

 

Results

 

Among 66 subjects, 2 participants from the MBSR group were excluded because of missing more than 2 sessions. Also, three participants were excluded because of did not complete the questionnaires in post-test or follow-up who one of them were from MBSR group and three participants from TAU group. Table 2 showed demographic characteristics of the subjects and results of the randomization check. The results of t-test for differences between the MBSR and TAU groups in age variable and Chi-square test in other variables showed that there was no significant difference between demographic variables in two groups and the subjects were randomly assigned to two groups.

Discussion

 

This study compared efficacy of MBSR and Treatment As Usual (TAU) in perceived stress and mental health of patients with tension headache. Although MBSR is recognized as an effective treatment for stress symptoms and pain, there is a need to examine its efficacy for the treatment of mental health problems in patients with tension headache, which is one of the common complaints in the population.

 

The findings of our study demonstrate enhanced general mental health in the GSI index of BSI. In some study, significant improvements by MBSR intervention were reported on all indexes of the 36-item Short Form Health Survey (SF-36).[20,24] Studies showed significant reduction in psychological problems in the Symptom Checklist-90-Revised (SCL-90-R) subscale such as anxiety and depression by MBSR after intervention and 1-year follow-up.[5] Reibel et al. showed MBSR in patients with chronic pain reported a decrease in medical symptoms such as anxiety, depression, and pain.[5] It has been shown that tension headache and anxiety are accompanied with deficits in controlled cognitive processing such as sustained attention and working memory.[25] Negative emotions may amplify suffering associated with pain perception.

 

MBSR implements the following mechanisms to improve the patient’s mental status: First, mindfulness leads to increased awareness for what is happening in each moment, with an accepting attitude, without getting caught up in habitual thoughts, emotions, and behavior patterns. The increased awareness then gives rise to new ways to respond and cope in relation to oneself and the world around.[3] Mindfulness establishes a sense of self that is greater than one’s thoughts, feelings, and bodily sensation such as pain. Mindfulness exercises, learned clients develop an �observer�self�. With this ability, they can observe their thoughts and feelings in a nonreactive and nonjudgmental way that previously avoided, that previously avoided thoughts and feelings be observed in a nonreactive and nonjudgmental way. The clients learn to notice thoughts without necessarily acting on them, being controlled by them, or believing them.[3]

 

Second, mindfulness helps the client develop persistence in taking steps in valued directions that are important to them. Most clients with chronic pain want to become pain free rather than living the vital lives of their choice. But the MBSR program trained them to engage in valued action despite the the pain. Studies have shown attention and emotional reaction to pain has an important role in becoming persistent the pain.[26] Emotional and cognitive components can modulate attention to pain and worry about it that could intensify pain and disrupt the patients activities.[27,28]

 

Third, findings from some studies indicate that MBSR can alter the function of the brain that is responsible for affect regulation and the areas that govern how we react to stressful impulses, and this in turn may normalize body functions such as breathing, heart rate, and immune function.[29,30] Mindfulness practice reduces reactivity to distressing thoughts and feelings that comorbid and strengthen pain perception.[31] Also mindfulness may lessen psychophysiological activation related to stress and mood dysfunction by strengthening positive reappraisal and emotion regulation skills.[32]

 

The strength of this study is the use of a new effective psychotherapy in reducing the stress on a complaint that is less studied, but it is a common medical problem. The implications of our study are using a simple psychotherapy that does not make too much cognitive demand and is readily usable as a coping skill for the patient with tension headache. Therefore, the health-care professionals related to this complaint and the patient will be able to use this treatment. Also, MBSR will change the patient’s lifestyle who would be exacerbated by his/her problem. The main limitation of this study was the lack of comparison between MBSR and the gold standard psychotherapies such as cognitive behavior therapy (CBT). It is suggested that future studies need to compare the efficacy of MBSR and other traditional and newer cognitive behavioral therapies in patients with tension headache.

 

Conclusion

 

Our study supports the hypothesis that patients suffering from tension headache can enhance their general mental health by participating in the MBSR program. In summary, the results of the present study suggest that MBSR can reduce pain-related anxiety and interference in daily activities in the short term. The unique features of mindfulness exercises are easy training and no need to complex cognitive abilities.

In conclusion,�while short-term stress is helpful, long-term stress can eventually lead to a variety of health issues, including anxiety and depression as well as neck and back pain, headache and disc herniation. Fortunately, mindfulness interventions, such as chiropractic care and mindfulness-based stress reduction (MBSR) are safe and effective stress management alternative treatment options. Finally, the article above demonstrated evidence-based results that MBSR could reduce stress and improve general mental health in patients with tension headache.

Additional Topics: Back Pain

 

According to statistics, approximately 80% of people will experience symptoms of back pain at least once throughout their lifetimes. Back pain is a common complaint which can result due to a variety of injuries and/or conditions. Often times, the natural degeneration of the spine with age can cause back pain. Herniated discs occur when the soft, gel-like center of an intervertebral disc pushes through a tear in its surrounding, outer ring of cartilage, compressing and irritating the nerve roots. Disc herniations most commonly occur along the lower back, or lumbar spine, but they may also occur along the cervical spine, or neck. The impingement of the nerves found in the low back due to injury and/or an aggravated condition can lead to symptoms of sciatica.
