Back Clinic Neuropathy Treatment Team. Peripheral neuropathy is a result of damage to peripheral nerves. This often causes weakness, numbness, and pain, usually in the hands and feet. It can also affect other areas of your body. The peripheral nervous system sends information from the brain and spinal cord (central nervous system) to the body. It can result from traumatic injuries, infections, metabolic problems, inherited causes, and exposure to toxins. One of the most common causes is diabetes mellitus.
People generally describe the pain as stabbing, burning, or tingling. Symptoms can improve, especially if caused by a treatable condition. Medications can reduce the pain of peripheral neuropathy. It can affect one nerve (mononeuropathy), two or more nerves in different areas (multiple mononeuropathies), or many nerves (polyneuropathy). Carpal tunnel syndrome is an example of mononeuropathy. Most people with peripheral neuropathy have polyneuropathy. Seek medical attention right away if there is unusual tingling, weakness, or pain in your hands or feet. Early diagnosis and treatment offer the best chance for controlling your symptoms and preventing further damage to the peripheral nerves. Testimonies http://bit.ly/elpasoneuropathy

When the sensory system is affected by injury or disease, the nerves within that system can’t work properly to transmit sensations and feelings into the brain. This frequently contributes to a feeling of numbness, or lack of sensation. However, in certain cases, when this system is damaged, people may experience pain in the affected area.
Neuropathic pain does not start abruptly or resolve quickly; it’s a chronic pain condition which leads to persistent pain symptoms. For most individuals, the intensity of their symptoms may wax and wane throughout the day. Although neuropathic pain is supposed to be related to peripheral nerve health issues, like neuropathy caused by diabetes or spinal stenosis, injuries to the brain or spinal cord may also lead to chronic neuropathic pain. Neuropathic pain is also referred to as nerve pain.
Neuropathic pain may be contrasted to nociceptive pain. Neuropathic pain does not develop to any specific circumstance or outside stimulus, but rather, the symptoms occur simply because the nervous system may not be working accordingly. As a matter of fact, individuals can also experience neuropathic pain even when the aching or injured body part is not actually there. This condition is called phantom limb pain, which may occur in people after they’ve had an amputation.
Nociceptive pain is generally acute and develops in response to a specific circumstance, such as when someone experiences a sudden injury, like hammering a finger with a hammer or stubbing a toe when walking barefoot. Moreover, nociceptive pain tends to go away once the affected site heals. The body contains specialized nerve cells, known as nociceptors, which detect noxious stimuli that could damage the body, such as extreme heat or cold, pressure, pinching, and exposure to chemicals. These warning signals are then passed along the nervous system to the brain, resulting in nociceptive pain.
What are the Risk Factors for Neuropathic Pain?
Anything that contributes to a lack of function within the sensory nervous system can lead to neuropathic pain. As such, nerve health issues from carpal tunnel syndrome, or similar conditions, can ultimately trigger neuropathic pain. Trauma, resulting in nerve injury, may lead to neuropathic pain. Other conditions which could predispose individuals to developing neuropathic pain include: diabetes, vitamin deficiencies, cancer, HIV, stroke, multiple sclerosis, shingles, and even some cancer treatments.
What are the Causes of Neuropathic Pain?
There are many causes from which individuals may develop neuropathic pain. But on a cellular level, one explanation is an increased release of certain receptors that indicate pain, together with a diminished ability of the nerves to modulate these signals, leads to the sensation of pain originating from the affected region. Additionally, in the spinal cord, the region which exerts painful signs is rearranged with corresponding changes in hormones and loss of normally-functioning mobile bodies. Those alterations result in the perception of pain in the absence of external stimulation. In the brain, the ability to block pain can be affected following an injury, such as stroke or trauma from an injury. As time passes, additional cell damage happens and the feeling of pain continues. Neuropathic pain is also related to diabetes, chronic alcohol intake, certain cancers, vitamin B deficiency, diseases, other nerve-related diseases, toxins, and specific drugs.
What are the Symptoms of Neuropathic Pain?
Contrary to other neurological conditions, identification of neuropathic pain can be challenging. However, several, if any, objective signals may be present. Healthcare professionals have to decipher and translate an assortment of words which patients use to describe their pain. Patients may describe their symptoms as sharp, dull, hot, cold, sensitive, itchy, deep, stinging, burning, among a variety of other descriptive terms. Additionally, some patients may experience pain through light touch or pressure.
In an effort to help identify how much pain patients could be undergoing, different scales are often used. Patients are asked to rate their pain according to a visual scale or numerical graph. Many examples of pain scales exist, such as the one demonstrated below. Often, pictures of faces depicting a variety of levels of pain may be helpful when individuals have a difficult time describing the quantity of pain they are experiencing.
Chronic Pain and Mental Health
For many, the impact of chronic pain may not be limited to the pain ; it may also negatively influence their mental state. New research studies conducted by scientists at the Northwestern University in Chicago can explain why individuals who have chronic pain also suffer with seemingly unrelated health issues, such as depression, stress, lack of sleep and difficulty concentrating.
The evaluation demonstrated that people with chronic pain show different regions of the brain which are always active, most specifically, the area associated with mood and attention. This continuous action rewires nerve connections from the brain and leaves chronic pain sufferers at greater risk for psychological problems. Researchers suggested that getting pain signals constantly could result in mental rewiring that adversely affects the mind. The rewiring compels their brains to devote mental resources differently to deal with everyday tasks, from mathematics, to recalling a shopping list, to feeling happy.
The pain-brain connection has been well recorded, at least anecdotally, and lots of healthcare professionals say they’ve seen first-hand the way the patient’s mental state can go downhill when they endure chronic pain. Misconceptions about the pain-brain connection may have emerged from a lack of evidence that pain has a measurable, lasting influence on the brain. Researchers expect that with additional research into the mechanisms of how chronic pain makes people more susceptible to mood disorders, people are going to have the ability to better manage their overall well-being.
Culture and Chronic Pain
Many things contribute to the way we experience and express pain, however, it has also been recently suggested by researchers that culture relates directly into the expression of pain. Our upbringing and societal values affect how we express pain and also its own nature, intensity and length. However, these variables aren’t as obvious as socio-psychological values, such as age and sex.
Research states that chronic pain is a multifaceted process and the concurrent interplay between pathophysiology, cognitive, affective, behavioral and sociocultural factors summate to what is referred to as the chronic pain experience. It’s emerged that chronic pain is experienced differently among patients of varied cultures and ethnicities.
Some cultures encourage the expression of pain, particularly in the southern Mediterranean and Middle East. Other individuals suppress it, as in the many lessons to our kids about behaving bravely and not crying. Pain is recognized as part of the human experience. We are apt to assume that communication about pain will seamlessly cross cultural boundaries. But people in pain are subject to the manners their civilizations have trained them to experience and express pain.
Both individuals in pain and healthcare professionals experience difficulties communicating pain across ethnic borders. In a matter like pain, where effective communication can have far-reaching implications for medical care, quality of life and potentially survival, the role of culture in pain communicating remains under-evaluated. Persistent pain is a multidimensional, a composite encounter formed by interweaving and co-influencing biological and psychosocial factors. Knowing the culmination of these factors is critical to understanding the differences of its manifestation and management.
How is Neuropathic Pain Diagnosed?
The diagnosis of neuropathic pain relies upon additional evaluation of an individual’s history. If underlying nerve damage is suspected, then analysis of the nerves together with testing may be justified. The most common means to assess whether or not a nerve is injured is using electrodiagnostic medicine. This medical subspecialty utilizes techniques of nerve conduction studies with electromyelography (NCS/EMG). Clinical evaluation may show evidence of loss of work, and can include evaluation of light touch, the capacity to differentiate sharp out of dull pain and the ability to discern temperature, as well as the evaluation of vibration.
After a thorough clinical examination is completed, the electrodiagnostic analysis could be planned. These studies are conducted by specially trained neurologist and physiatrists. If neuropathy is suspected, a hunt for reversible causes ought to be accomplished. This can include blood function for vitamin deficiencies or thyroid problems, and imaging studies to exclude a structural lesion affecting the spinal cord. Depending on the results of this testing, there might be a means to decrease the intensity of the neuropathy and possibly reduce the pain that a patient is undergoing.
Regrettably, in many conditions, even good control of the underlying cause of the neuropathy can’t reverse the neuropathic pain. This is commonly seen in patients with diabetic neuropathy. In rare instances, there may be signs of changes in the skin and hair growth pattern in an affected region. These alterations may be associated with changes in perspiration. If present, these changes can help identify the likely presence of neuropathic pain related to a condition known as complex regional pain syndrome.
Dr. Alex Jimenez’s Insight
Neuropathic pain is a chronic pain condition which is generally associated with direct damage or injury to the nervous system or nerves. This type of pain is different from nociceptive pain, or the typical sensation of pain. Nociceptive pain is an acute or sudden sensation of pain which causes the nervous system to send signals of pain immediately after the trauma occurred. With neuropathic pain, however, patients may experience shooting, burning pain without any direct damage or injury. Understanding the possible causes of the patient’s neuropathic pain versus any other type of pain, can help healthcare professionals find better ways to treat chronic pain conditions.
What is the Treatment for Neuropathic Pain?
Various medicines are used in an attempt to treat neuropathic pain. The majority of these drugs are utilized off-label, which means that the medicine was approved by the FDA to treat different conditions and was then recognized as being advantageous to treat neuropathic pain. Tricyclic antidepressants, such as amitriptyline, nortriptyline and desipramine, have been prescribed for management of neuropathic pain for several years.
Some individuals find that these may be very effective in giving them relief. Other kinds of antidepressants have been shown to offer some relief. Selective serotonin reuptake inhibitors, or SSRIs, such as paroxetine and citalopram, and other antidepressants , such as venlafaxine and bupropion, have been utilized in certain patients. Another frequent treatment of neuropathic pain incorporates antiseizure medications, including carbamazepine, phenytoin, gabapentin, lamotrigine, and others.
In acute cases of painful neuropathy which don’t respond to first-line brokers, drugs typically utilized to treat heart arrhythmias may be of some benefit; however, these can lead to significant side effects and often have to be monitored closely. Medications applied directly to the skin can offer modest to perceptible benefit for some patients. The forms commonly used include lidocaine (in patch or gel type) or capsaicin.
Treating neuropathic pain is dependent on the underlying cause. If the cause is reversible, then the peripheral nerves can regenerate and the pain will abate; nonetheless, this reduction in pain may take several months to years. Several other alternative treatment options, including chiropractic care and physical therapy, may also be utilized in order to help relieve tension and stress along the nerves, ultimately helping to improve painful symptoms.
What is the Prognosis for Neuropathic Pain?
Many individuals with neuropathic pain are able to get some measure of aid, even when their pain persists. Although neuropathic pain isn’t dangerous to a patient, the presence of chronic pain can negatively affect quality of life. Patients with chronic nerve pain might suffer from sleep deprivation or mood disorders, including depression, anxiety and stress, as previously mentioned above. Because of the inherent alopecia and lack of sensory feedback, patients are at risk of developing injury or infection or unknowingly causing an escalation of a present injury. Therefore, it’s essential to seek immediate medical attention and follow specific guidelines directed by a healthcare professional for safety and caution.
Can Neuropathic Pain be Prevented?
The best way to prevent neuropathic pain is to avoid the development or progression of neuropathy. Monitoring and changing lifestyle options, including restricting the use of alcohol and tobacco; keeping a healthy weight to lower the chance of diabetes, degenerative joint disease, or stroke; and having great ergonomic form at work or when practicing hobbies to lower the risk of repetitive stress injury are strategies to decrease the probability of developing neuropathy and potential neuropathic pain. Make sure to seek immediate medical attention in the case of any symptoms associated with neuropathic pain in order to proceed with the most appropriate treatment approach.�The scope of our information is limited to chiropractic as well as to spinal injuries and conditions.

Additional Topics: Back Pain
Back pain is one of the most prevalent causes for disability and missed days at work worldwide. As a matter of fact, back pain has been attributed as the second most common reason for doctor office visits, outnumbered only by upper-respiratory infections. Approximately 80 percent of the population will experience some type of back pain at least once throughout their life. The spine is a complex structure made up of bones, joints, ligaments and muscles, among other soft tissues. Because of this, injuries and/or aggravated conditions, such as herniated discs, can eventually lead to symptoms of back pain. Sports injuries or automobile accident injuries are often the most frequent cause of back pain, however, sometimes the simplest of movements can have painful results. Fortunately, alternative treatment options, such as chiropractic care, can help ease back pain through the use of spinal adjustments and manual manipulations, ultimately improving pain relief.
Neuropathy Presentation II:�El Paso, TX. Chiropractor, Dr. Alexander Jimenez�continues the overview with neuropathy part II. Continued are the most common neuropathies to be seen in practice. Because the human body is composed of many different kinds of nerves which perform different functions, nerve damage is classified into several types. Neuropathy can also be classified according to the location of the nerves being affected and according to the disease causing it. For instance, neuropathy caused by diabetes is called diabetic neuropathy. Furthermore, depending on which nerves are affected will depend on the symptoms that will manifest. The complications which follow neuropathy depends on the type of nerves that are damaged. According to Dr. Jimenez, different neuropathies can cause numbness and/or tingling sensations, increased pain or the loss of ability to feel pain, muscle weakness along with twitching and cramps, even dizziness and/or loss of bladder control function.

Classification Of Nerve Injuries Resulting In Neuropathy
Neurapraxia – This is a transient episode of motor paralysis with little or no sensory or autonomic dysfunction; no disruption of the nerve or its sheath occurs; with removal of the compressing force, recovery should be complete
Axonotmesis – This is a more severe nerve injury, in which the axon is disrupted but the Schwann sheath is maintained; motor, sensory, and autonomic paralysis results; recovery can occur if the compressing force is removed in a timely fashion and if the axon regenerates
Neurotmesis – This is the most serious injury, in which both the nerve and its sheath are disrupted; although recovery may occur, it is always incomplete, secondary to loss of nerve continuity

Neuropathy is a medical term used to describe a collection of general diseases or malfunctions which affect the nerves. The causes of neuropathy, or nerve damage, can vary greatly among each individual and these may be caused by a number of different diseases, injuries, infections and even vitamin deficiency states. However, neuropathy can most commonly affect the nerves that control the motor and sensory nerves. Because the human body is composed of many different kinds of nerves which perform different functions, nerve damage is classified into several types. Neuropathy can also be classified according to the location of the nerves being affected and according to the disease causing it. For instance, neuropathy caused by diabetes is called diabetic neuropathy. Furthermore, depending on which nerves are affected will depend on the symptoms that will manifest as a result. Below we will discuss several specific types of neuropathies clinically treated by chiropractors, physical therapists and physical medicine doctors alike, as well as briefly describing their causes and their symptoms.
Brachial Plexopathies
Brachial plexopathy is a type of peripheral neuropathy, which affects the nerves that transmit messages from the brain and the spinal cord to the rest of the body. This kind of nerve damage occurs when harm affects the brachial plexus, a region found on each side of the neck where nerve roots from the spinal cord branch out into each arm’s nerves. Damage, injury or a condition that impacts these nerve roots can result in pain, decreased mobility and reduced sensation in the arm and shoulder. In some cases, no cause can be identified.
Erb’s Palsy
Erb’s Palsy, also known as�Erb�Duchenne palsy or Waiter’s tip palsy, is identified as a paralysis of the arm caused by damage or injury to the nerves in the neck which form part of the brachial plexus. The most common mechanism of injury in adults with Erb’s Palsy is a patient who fell forward while holding onto something behind them. Erb�Duchenne palsy can also happen to an infant during childbirth, most commonly, but not exclusively, from shoulder dystocia during a difficult birth. To be more precise, this type of brachial plexopathy results from damage to the C5-C6 nerve roots along the brachial plexus in the neck. Symptoms of Erb’s Palsy include dermatomal distribution of sensory disruption followed by weakness or paralysis in the deltoid, biceps, and brachialis muscles, leading to the �waiter�s tip� position associated with this type of neuropathy. While many infants can recover on their own from this type of brachial plexopathy, some may require rehabilitation.
Klumpke’s Palsy
Klumpke’s Palsy, also known as Klumpke’s paralysis or�Dejerine�Klumpke palsy, is a partial palsy in the nerve roots of the brachial plexus located along the cervical spine, or neck. It is named after�Augusta D�jerine-Klumpke, an American-born French medical doctor acknowledged for her work in neuroanatomy. Klumpke’s Palsy is characterized as a form of paralysis involving the muscles of the forearm and hand, which occurs to�infants during childbirth if their arm is pulled overhead.�Dejerine�Klumpke palsy can also occur to adults with overhead traction injuries caused by harm to the C8-T1 nerve roots in the brachial plexus and upper thoracic region of the spine. Symptoms of Klumpke’s paralysis include dermatomal distribution of sensory disruption, weakness or paralysis, in the wrist flexors and pronators as well as in the muscles of the hand. This type of brachial plexopathy may often lead to Horner�s syndrome, a collection of symptoms which manifest when a set of nerves, known as the sympathetic trunk, are damaged or injured due to T1 involvement. This form of neuropathy is identified by resulting�in a �claw hand� appearance, where the forearm is supinated with the wrist hyperextended, together with finger flexion.
Entrapment Neuropathies
Entrapment neuropathy, also known as nerve compression syndrome or compression neuropathy, is best-known as nerve damage or a type of neuropathy caused by direct pressure on a nerve. Common symptoms include pain and discomfort, tingling or burning sensations, numbness and muscle weakness which affects only a particular part of the human body, depending on which nerve is affected. A nerve can become compressed as a result of a constant external force or due to a lesion, such as a tumor. Additionally, some conditions can make the nerves more susceptible to compression, including diabetes, where the nerves are rendered more sensitive to minor degrees of compression due to their already compromised supply of blood. Nerve damage caused by a single episode of harm can be considered an entrapment neuropathy, however, it is generally not classified under this group of compression neuropathy or nerve compression syndrome.
Thoracic Outlet Syndromes
Thoracic outlet syndromes are a group of disorders which develop when the nerves or blood vessels between the collarbone and the thoracic outlet, located in the region of the first rib, are compressed. As a result, this can cause pain and discomfort in the neck and shoulders as well as numbness in the fingers. There are a number of types of thoracic outlet syndromes, including neurogenic, or neurological, thoracic outlet syndrome, specifically caused by the compression of the brachial plexus, vascular thoracic outlet syndrome, which is caused specifically by the compression of the veins, known as venous thoracic outlet syndrome, or arteries, known as arterial thoracic outlet syndrome, and nonspecific-type thoracic outlet syndrome, which is considered to be idiopathic and has been described to worsen with activity. Several healthcare professionals believe that nonspecific-type thoracic outlet syndrome doesn’t exist, while others claim it to be a common disorders. However, the majority of thoracic outlet syndromes are often classified as neurogenic.
Thoracic outlet syndromes are caused by the compression of the cervical rib, an extra “rib” in the seventh cervical vertebra, subclavius muscle tension, improper posture or�excessive thoracic kyphosis, physical trauma, repetitive activity, obesity and pregnancy. Thoracic outlet syndromes can vary depending on which structures are compressed. Thoracic outlet syndromes can be diagnosed using tests, such as the Adsons test, the Allen maneuver, the Costoclavicular maneuver, the Halstead maneuver, the�Reverse bakody maneuver, the Roos test, the Shoulder compression test and the Wright test. Thoracic outlet syndromes can cause permanent neurological damage if not diagnosed and treated early.
Median Nerve Entrapment
Median nerve entrapment or median nerve entrapment syndrome, is a mononeuropathy, a condition that impacts only a single nerve or nerve group outside the brain and spinal cord, which affects the movement of or sensation in the hand. Median nerve entrapment is caused by the compression of the median nerve found in the elbow or distally in the forearm or wrist. Symptoms include sensory disruption in the lateral portion of the palmar aspect of the hand and dorsal finger tips of the same fingers. In addition, motor fibers may also be affected in the forearm, if applicable, including the muscles of the thenar eminence, such as the abductor pollicis brevis, the opponens pollicis, and the flexor pollicis brevis. Other forms of median nerve entrapment syndromes include: pronator teres syndrome and carpal tunnel syndrome.
Pronator teres syndrome is characterized as the compression of the median nerve at the elbow. It is considered rare compared to carpal tunnel syndrome. Pronator teres syndrome is caused by repetitive movement, pronator teres muscle inflammation and thickened bicipital aponeurosis. Clinical findings for this type of neuropathy include, tenderness with palpation of the pronator teres muscle, pain with resisted pronation of the arm, flexor pollicus longus and flexor digitorum profundus involvement, otherwise, symptoms manifestations for pronator teres syndrome may appear similar to carpal tunnel syndrome but without positive wrist orthopedics.
Carpal tunnel syndrome is characterized as the compression of the median nerve at the wrist. Carpal tunnel syndrome is identified by symptoms of pain and discomfort, tingling sensations in the thumb, index finger, middle finger and the thumb side of the ring fingers, and numbness. These can generally start gradually and may extend up the arm. Advanced instances of carpal tunnel syndrome may cause weakened grip strength where the muscles at the base of the thumb may waste away if left untreated for an extended period of time. In many cases, carpal tunnel syndrome may affect both hands or arms. Carpal tunnel syndrome is caused by repetitive movements, hypothyroidism, obesity, rheumatoid arthritis, diabetes and pregnancy. Orthopedic tests utilized to diagnose carpal tunnel syndrome include the use of the Tinel�s Sign, positive if tapping over the median nerve reproduces/exacerbates symptoms, the�Phalen�s Maneuver/Prayer Sign, performed by bringing the hands together, with wrists flexed, and is repeated in reverse with the wrists extended, for at least 60 seconds, and is considered positive if tests reproduce/exacerbate symptoms, and the�Wringing Test, if wringing a towel produces paresthesia.
Ulnar Nerve Entrapment
Ulnar nerve entrapment is a condition where the ulnar nerve itself becomes physically trapped or pinched, resulting in symptoms of pain, numbness and weakness which extends throughout the little finger, the ulnar half of the ring finger and throughout the intrinsic muscles of the hand. Symptoms or ulnar nerve entrapment ultimately involve sensory disruption in the medial two digits of the palmar and dorsal aspects of the hand. Symptoms of ulnar nerve entrapment may vary depending on the specific location of the ulnar nerve compression or impingement. These may also be classified as motor, sensory or both, depending on the location of the injury. If motor fibers are affected in the hand, all fingers, besides the thumb, may become weakened, described as general hand weakness. The most common location of ulnar nerve entrapment is within the cubital tunnel. Other forms of ulnar nerve entrapment include: cubital tunnel syndrome and tunnel of Guyon syndrome.
Cubital tunnel syndrome is identified by the compression or impingement of the ulnar nerve in the cubital tunnel at the elbow. It is considered to be the second most common entrapment neuropathy which affects the upper extremities, following carpal tunnel syndrome. Symptoms of cubital tunnel syndrome are characterized by pain and discomfort along the region of the ulnar nerve entrapment, along with sensory impairment, paresis and paresthesia.�Causes of cubital tunnel syndrome include, repetitive movements, hypothyroidism, obesity, diabetes, physical trauma or injury to the cubital tunnel, and prolonged sitting with pressure on bent elbow.
Tunnel of Guyon syndrome, or Guyon’s canal syndrome, is identified by the compression or impingement of the ulnar nerve at the wrist, particularly along an anatomical space in the wrist known as Guyon’s canal. Guyon’s canal syndrome may also be referred to as ulnar tunnel syndrome. Symptoms of tunnel of Guyon syndrome are similar to those of cubital tunnel syndrome with slight variations depending on the region of ulnar nerve entrapment.�Causes of tunnel of Guyon syndrome include, repetitive movements, long term crutch use, fracture of the hamate, a carpal bone, due to a ganglion cyst, hypothyroidism, obesity, rheumatoid arthritis and diabetes.�Orthopedic tests utilized to diagnose Guyon’s canal syndrome include the use of the�Tinel�s Sign, positive if test over the ulnar nerve at the wrist elicits symptoms, the Wartenberg Sign, positive if the 5th digit abducts when patient performs hard grip strength test or attempts to squeeze fingers together and reduced two-point discrimination in the hand.
Radial Nerve Entrapment
Radial nerve entrapment, also known as radial tunnel syndrome, is a condition caused by the compression of the radial nerve, which travels from the brachial plexus, to the hand and wrist. Healthcare professionals believe that radial tunnel syndrome occurs because the radial nerve becomes irritated or inflamed due to the friction caused by the impingement of the muscles in the forearm. Radial nerve entrapment manifests symptoms of sensory disruption in the lateral three and a half digits of the dorsal aspect of the hand. Motor�fibers may also be affected along the�posterior arm and extensor compartment of the forearm, and wrist drop may be seen. Other forms of radial tunnel syndrome include: spiral groove entrapment, where all radial nerve innervated muscles below entrapment are affected,�Saturday night palsy caused due to sleeping on your own arm and the brachioradialis & triceps reflexes are both diminished, supinator syndrome, caused by the compression at the arcade of Frohse with no change in reflexes. Posterior interosseous syndrome, or radial tunnel syndrome, also elicits no change in reflexes.
Sciatic Nerve Entrapment
Sciatic nerve entrapment is a condition caused by the compression of the sciatic nerve, the longest and largest nerve in the human body, which travels from the low back, down through the buttocks, thighs, legs and into the foot. The collection of symptoms which manifest as a result of sciatic nerve entrapment, including pain and discomfort, tingling and burning sensations, and numbness as well as weakness in the lower extremitites, is commonly known as sciatica. Sciatic nerve entrapment, or sciatica, can be caused by a variety of injuries and/or aggravated conditions which can lead to the compression of the sciatic nerve, including, but not limited to, disc herniation and spinal stenosis. However, symptoms of sciatic nerve entrapment may vary depending on the location of the compression of the sciatic nerve. Other conditions caused by the compression of the sciatic nerve include: piriformis syndrome, peroneal nerve entrapment and tarsal tunnel syndrome.
Piriformis syndrome is a condition which occurs due to the compression of the sciatic nerve as a result of the irritation or inflammation of the piriformis muscle. Symptoms of piriformis syndrome may include pain and discomfort, followed by numbness in the buttocks and down the leg. Symptoms may worsen with regular activities, such as sitting and running. Piriformis syndrome is caused by anatomic variation or due to piriformis overuse/tension. Piriformis syndrome diagnosis exams include, a positive Lase?gue test, where the healthcare professional�extends the patient�s leg passively, while the patient is lying supine,�test is positive if the maneuver is limited by pain, and through the use of tenderness and palpable tension in piriformis muscle which elicits symptoms.
Peroneal nerve entrapment is a condition which occurs when the peroneal or the fibular branch of the sciatic nerve are compressed at the fibular head. Tinel�s sign may be present at the fibular region of the head and/or neck. Peroneal nerve entrapment generally affects the common peroneal nerve, therefore, motor and sensory symptoms may manifest, including, weakness of the ankle dorsiflexion and eversion, or the tibialis anterior. Other symptoms of peroneal nerve entrapment may include sensory disruption on the dorsum of the foot and lateral aspect of the calf. Common peroneal nerve entrapement at the fibular head is the most common nerve entrapment syndrome in the lower extremities.
Tarsal tunnel syndrome, also known as posterior tibial neuralgia, is a condition caused by the compression of the tibial nerve as it travels through the tarsal tunnel, found along the region of the inner leg, posterior to the medial malleolus, or the bump on the inside of the ankle. Tarsal tunnel syndrome can manifest symptoms of pain and discomfort, burning or tingling sensations, and numbness along the big toe and the first three toes. However, symptoms may vary slightly depending on the area of compression, where the entire foot may manifest the symptoms previously described. Other symptoms associated with posterior tibial neuralgia include sensory changes in the sole of the foot. Tinel�s sign may be present with percussion posterior to the medial malleolus. The exact cause of tarsal tunnel syndrome may be difficult to determine and it is essential to receive a proper diagnosis to determine the source of the symptoms.
Radiculopathy
Radiculopathy is a mononeuropathy,�a condition that impacts only a single nerve or nerve group outside the brain and spinal cord, which affects the movement of or sensation in one specific area. It is often associated with neuropathy involving spinal nerve roots and presents as changes in sensory and/or motor function affecting a single or a few nerve root level(s). The most common types of radiculopathies include: sciatica and cervical radiculopathy. The most prevalent causes of radiculopathy include, disc herniation, osteophytes, spinal stenosis, trauma, diabetes, epidural abscess or metastasis, nerve sheath tumors, such as schwannomas and neurofibromas, Guillain-Barre? syndrome, Herpes Zoster, or shingles, Lyme disease, cytomegalovirus, myxedema and/or thyroid disorder, and idiopathic neuritis.
Narrowing down some of the most common causes of radiculopathy, symptoms can manifest due to disc herniation which most commonly affects the nerve roots along the C6, C7, L5 & S1 vertebrae of the spine, spinal stenosis and lumbar stenosis which may produce neurogenic claudication, and pain and weakness with ambulation. Cervical stenosis may present with mixed radiculopathy and myelopathy due to long tract involvement. Symptoms may also manifest due to trauma, because it may lead to compression, trauma or avulsion of the nerve roots, diabetes, which is most�likely to cause a polyneuropathy, but mononeuropathy is possible, and Herpes Zoster, or shingles, most often on the trunk, accompanied by vesicular lesions in a single dermatome. If pain persists past vesicular regression, radiculopathy may instead be considered post-herpetic neuralgia.
Patients with a history of radiculopathy will often complain of burning pain or tingling sensations which radiates or shoots down an affected area in a “dermatomal” pattern. Occasionally, patients will complain of motor weakness, however if onset is recent, there is often no motor involvement. The diagnosis of radiculopathy can depend on a variety of exams.�Most often, hypoesthesia may be present in the affected dermatome level. It’s recommended to�evaluate for pain, as light touch can be difficult for these patient�s to distinguish. Fasciculations and/or atrophy may be seen if radiculopathy is chronic, due to the lower motor neuron being compressed or impinged. Motor weakness may be seen in muscles innervated by the same root level. Orthopedic tests for the diagnosis of radiculopathy may include: the straight-leg raise test (SLR), where pain between 10 to 60 degrees likely indicates nerve root compression, the�Well-leg raise/Crossed straight-leg raise test (WLR), where if positive, 90 percent specificity for L/S nerve root compression may be present, the Valsalva Maneuver, where its considered positive if there is an increase in radicular symptoms, and spinal percussion, where pain may indicate metastatic disease, abscess or osteomyelitis.
Specific radiculopathy patterns may also develop as a result of different regions being affected. Radiculopathy along the T1 can cause Horner�s syndrome, a combination of symptoms caused by the disruption of a nerve pathway from the brain to the face and eye on one side of the body. This is due to its effect on cervical sympathetic ganglia, includind ptosis, miosis, anhidrosis. Radiculopathy below the L1, can cause Cauda Equina syndrome, a condition caused by damage or injury to the bundle of nerves found below the end of the spinal cord, known as the cauda equina. This type of radiculopathy may manifest symptoms of saddle anesthesia, sensory loss in the S2-S5 distribution, urinary retention or overflow incontinence, constipation, decreased rectal tone or fecal incontinence, and loss of erectile function. Individuals with these signs and symptoms must be referred for emergency care immediately to prevent permanent dysfunction.
Other patterns of neuropathy can include the cape/shawl distribution of symptoms, identified by an intramedullary lesion, such as syringomyeli, intramedullary tumor and central cord damage. Stocking and glove distribution of symptoms may manifest as a result of diabetes mellitus,�B12 deficiency, alcoholism and/or hepatitis,�HIV, and thyroid dysfunction and/or myxedema.
The cape/shawl pattern of neuropathy is characterized by symptoms occurring due to an intramedullary lesion, such as a tumor, syringomyelia or a hyperextension injury in patient with C/S spondylosis. It can also be characterized by loss of pain and temperature sensation in C/T dermatomes because of the arrangement of the lateral spinothalamic tract. The stocking and glove pattern may progress gradually depending on its specific stage. It can also be characterized as a symmetrical polyneuropathy, where the feet and legs are generally affected first, followed by the hands and arms. A vibration-like sensation in the smallest toes are also typically the first to go and the neuropathy symptoms may progress across the foot to the big toe and then upward through the ankle and leg, then hands, arms and finally to the trunk if the condition becomes severe. The most likely cause of this pattern may be attributed to diabetes mellitus, but other possible causes include, B12 deficiency, alcoholism, HIV, chemotherapy treatment, thyroid dysfunction and multiple other causes.
Diabetic Neuropathy
Diabetic neuropathy is medically defined as a collection of nerve damaging disorders associated with diabetes. These conditions are believed to occur as a result of a diabetic microvascular injury involving the small blood vessels, known as the vasa nervorum, which supply the nerves. Additionally, macrovascular conditions have also been considered to accumulate and cause diabetic neuropathy.�Diabetic neuropathy often presents as a polyneuropathy, or the simultaneous damage or disease of many peripheral nerves throughout the body, but it can also present as a mononeuropathy, usually with acute onset. Diabetic neuropathy most commonly affects the CN III, femoral and sciatic nerves. Diabetic neuropathy can affect all peripheral nerves, including the sensory neurons, motor neurons and, although rarely, the autonomic nervous system. As a result, diabetic neuropathy can affect all organs and systems, as these are all innervated. Diabetic neuropathy can manifest into a wide array of symptoms, including, but not limited to, pain, burning or tingling sensations, numbness, dizziness and trouble with balance.
Demyelinating Neuropathies
Demyelinating neuropathies can be individually defined by its two types: Acute inflammatory demyelinating polyneuropathy, best known as�Guillain-Barre? syndrome, or Chronic inflammatory demyelinating polyneuropathy.�Guillain-Barre? syndrome, abbreviated as AIDP, is identified as a rapid-onset muscle weakness caused when the immune system damages, harms or destroys the peripheral nervous system. Onset has been reported by around one to two weeks following viral infection with progressive weakness, loss of DTRs/areflexia, paresthesia in the hands and feet, more motor involvement than sensory, potential autonomic fiber involvement, elevated CSF protein, and EMG/NCV studies indicating demyelination.�Guillain-Barre? syndrome may require treatment with plasmapheresis or IV Ig therapy.�Chronic inflammatory demyelinating polyneuropathy, abbreviated as CIDP,�is identified as an acquired immune-mediated inflammatory disorder of the peripheral nervous system which appears similar to AIDP but does not follow infection. Symptoms must be present for at least 8 weeks for this diagnosis to be considered positive.�Anti-inflammatory treatments may help treat CIDP.

Additional Topics: Sciatica
Sciatica is medically referred to as a collection of symptoms, rather than a single injury and/or condition. Symptoms of sciatic nerve pain, or sciatica, can vary in frequency and intensity, however, it is most commonly described as a sudden, sharp (knife-like) or electrical pain that radiates from the low back down the buttocks, hips, thighs and legs into the foot. Other symptoms of sciatica may include, tingling or burning sensations, numbness and weakness along the length of the sciatic nerve. Sciatica most frequently affects individuals between the ages of 30 and 50 years. It may often develop as a result of the degeneration of the spine due to age, however, the compression and irritation of the sciatic nerve caused by a bulging or herniated disc, among other spinal health issues, may also cause sciatic nerve pain.
The vast array of symptoms caused by neuropathy, also known as peripheral neuropathy, reflect the fact that it may be caused by an equally broad range of ailments involving disease and damage to peripheral nerves.
Signs and Symptoms of Neuropathy
Depending on the reason and unique to each patient, signs and symptoms of neuropathy can include:�pain; tingling, burning or prickling sensations; increased sensitivity to touch; muscle weakness or wasting;�temporary or permanent numbness; paralysis; dysfunction in glands or organs; or impairment in urination and sexual functioning.
Such signs and symptoms are dependent on whether autonomic, sensory, or motor nerves, as well as a combination of them, are ultimately affected. Autonomic nerve damage can influence physiological functions like blood pressure or create gastrointestinal problems and issues. Damage or dysfunction in the sensory nerves may impact sensations and sense of equilibrium or balance, while harm to motor nerves may affect movement and reflexes. When both sensory and motor nerves are involved, the condition is known as sensorimotor polyneuropathy.
Diabetic Neuropathy Symptoms
Diabetic peripheral neuropathy, which affects between 12 and 50 percent of individuals with diabetes, is one of the most common types of neuropathy. Many times, symptoms include a gradual change in sensation, as well as pain and weakness in the feet and, although less commonly, the hands. As the neuropathy develops further, it can lead to a loss of sensation in the affected regions.
This lack of feeling raises the odds of harm to the affected areas, explains Matthew Villani, doctor of podiatric medicine at Central Florida Regional Hospital at Lake Mary. Without the pain to signal when there’s an issue, individuals with diabetic neuropathy may allow modest abrasions or blisters on their feet, for instance, to fester as sores or ulcers. “The ulcers can become infected since they are open wounds, which can also progress to bone infection. Unfortunately, it frequently requires amputations if it does progress to that point”, states Dr. Matthew Villani.
Chemotherapy-Associated Neuropathy Symptoms
Cancer patients may suffer with neuropathy induced by chemotherapy as well as by other drugs and/or medications used to treat the disease. Symptoms can include intense pain, impaired movement, changes in heart rate and blood pressure, issues with balance, difficulty breathing, paralysis, and even organ failure. After chemotherapy is done, the symptoms frequently abate swiftly, but occasionally they last more, or these may not go away at all.
HIV- and AIDS-Associated Neuropathy Symptoms
Individuals being treated for HIV or AIDS can develop neuropathy from effects of the virus and the drugs and/or medications used to treat it as well. Common symptoms include stiffness, burning, prickling, tingling, and loss of feeling in the toes and soles of their feet. Sometimes the nerves in the fingers, hands, and wrists are also affected. The drugs Videx (didanosine), Hivid (zalcitabine), and Zerit (stavudine) have been most commonly associated with neuropathic symptoms.
Inflammation-Associated Neuropathy Symptoms
Inflammation caused by infections, like herpes zoster (also known as shingles), Lyme disease, or hepatitis B and hepatitis C, may lead to neuropathy, as may inflammation caused by autoimmune disorders, such as vasculitis, sarcoidosis, or autoimmune disease. In such situations, the signs and symptoms generally include burning and tingling sensations or numbness.
Other Causes of Neuropathy Symptoms
Additional causes of neuropathy and associated signs and symptoms include metabolic disorders, such as hypoglycemia or kidney failure; autoimmune disorders, such as rheumatoid arthritis, lupus, Sjogren’s syndrome, and Guillain-Barr� syndrome; toxicity; hereditary disorders, such as Charcot-Marie-Tooth disorder; hormonal disorders; alcoholism; vitamin deficiencies; physical trauma or injury; compression; and repetitive stress. In addition, many individuals may experience idiopathic neuropathy signs and symptoms, meaning that healthcare professionals may not know the reason for their neuropathy.
Dr. Alex Jimenez’s Insight
Neuropathy can be caused by a variety of injuries and/or aggravated conditions, often manifesting into a plethora of associated signs and symptoms. While every type of neuropathy, such as diabetic neuropathy or autoimmune disease-associated neuropathy, develops its own unique group of signs and symptoms, many patients will often report common complaints. Individuals with neuropathy generally describe their pain as stabbing, burning or tingling in character. If you experience unusual or abnormal tingling or burning sensations, weakness and/or pain in your hands and feet, it’s essential to seek immediate medical attention in order to receive a proper diagnosis of the cause of your specific signs and symptoms. Early diagnosis may help prevent further nerve injury.
What are the Common Signs and Symptoms of Neuropathy?
“Although there’s a wide array of signs and symptoms associated with neuropathy, the type of pain that people encounter may be common in many aspects of the disorder”, notes Vernon Williams, MD, a sports neurologist and director of the Center for Sports Neurology and Pain Medicine at Cedars-Sini Kerlan-Jobe Institute in Los Angeles. “The character and quality of neuropathic pain will often be pain that is burning or electric in character.” Furthermore, he describes that the pain will frequently be associated with different symptoms, like paresthesia, or a lack of normal sensation associated with pain; allodynia, or a painful reaction to a stimulus that wouldn’t normally trigger pain signals; and hyperalgesia, or a striking or severe pain in response to a stimulus that normally causes moderate pain.
How is Neuropathy Diagnosed?
If you think you’re having any of the above neuropathy signs and symptoms, consult a healthcare professional. A number of tests can be done to diagnose neuropathy. “There are certain patterns of complaints that indicate neuropathy,” stated Dr. Williams, “so taking down a patient’s history which includes a description of these complaints is an important first step.”
“After that, your healthcare professional can perform a physical evaluation, including checking motor and sensory function, assessing deep tendon reflexes, as well as looking for signs and symptoms like allodynia and hyperalgesia,” Williams says. “Then we can even perform electrodiagnostic testing; the most common being electromyography and nerve conduction testing, where we can stimulate nerves and document responses, calculate the rate at which signals are being transmitted and see whether there are some areas where nerves are not transmitting signals normally,” Williams continues.
With needle tests, Williams states, “We can put modest needles into human muscles, and, according to what we see and listen together with all the needle in the muscle, we get details about the way the nerves supplying those muscle tissues are functioning. There are a number of unique tests that could be handy to identifying neuropathy, in addition to localizing where the abnormality is the most likely to be coming from”, concluded Dr.�Vernon Williams.
Often, blood tests may test for elevated blood glucose to see whether your neuropathy signs and symptoms could possibly be associated to type 2 diabetes, nutritional deficiencies, toxic elements, hereditary disorders, and evidence of an abnormal immune response. Your healthcare professional may also do a nerve biopsy, which normally involves removing a small segment of a sensory nerve to search for abnormalities, or even a skin biopsy to see if there’s a reduction in nerve endings.
To give yourself the best chance of an accurate diagnosis as well as relief from your neuropathy signs and symptoms, be prepared to describe everything you are experiencing in detail, even when you experience them, how long an episode persists, and the amount of pain, discomfort or loss of sensation or movement you experience. The more specific you are on the signs and symptoms you’re experiencing, the easier it’ll be for your doctor to understand what’s happening.

It may often develop as a result of the degeneration of the spine due to age, however, the compression and irritation of the sciatic nerve caused by a bulging or herniated disc, among other spinal health issues, may also cause sciatic nerve pain.
Neuropathy affects about 8 percent of individuals over the age of 55. Your nervous system is composed of 2 parts: the central nervous system and the peripheral nervous system. The nerves of your peripheral nervous system transmit messages between your central nervous system, that is your brain and spinal cord, along with the rest of the body.
These nerves regulate a massive range of functions throughout the body, such as voluntary muscle movement, involving the motor nerves, involuntary organ action, through the autonomic nerves, and also the perception of stimuli, involving the sensory nerves. Peripheral neuropathy, which is often simply referred to as “neuropathy,” is a state that happens when your nerves become damaged or injured, often times simply disrupted. It’s estimated that neuropathy affects roughly 2.4 percent of the general populace and approximately 8 percent of people older than age 55. However, this quote doesn’t include people affected by neuropathy caused by physical trauma to the nerves.
Types of Neuropathy
Neuropathy can affect any of the three types of peripheral nerves:
Sensory nerves, which transmit messages from the sensory organs, such as the eyes, nose, etc., to your brain;
Motor nerves, which track the conscious movement of your muscles; and
Autonomic nerves, which regulate the involuntary functions of your own body.
Sometimes, neuropathy will only impact one nerve. This is medically referred to as mononeuropathy and instances of it include:
Ulnar neuropathy, which affects the elbow;
Radial neuropathy, which affects the arms;
Peroneal neuropathy, which affects the knees;
Femoral neuropathy, which affects the thighs; and
Cervical neuropathy, which affects the neck.
Sometimes, two or more isolated nerves in separate regions of the body can become damaged, injured or disrupted, resulting in mononeuritis multiplex neuropathy. Most often, however, multiple peripheral nerves malfunction at the same time, a condition called polyneuropathy. According to the National Institute for Neurological Disorders and Stroke, or the NINDS, there are over 100 kinds of peripheral neuropathies.
Dr. Alex Jimenez’s Insight
Neuropathy is medically defined as a disease or dysfunction of one or more peripheral nerves, accompanied by common symptoms of pain, weakness and numbness. The peripheral nerves are in charge of transmitting messages from the central nervous system, the brain and the spinal cord, to the rest of the body. Neuropathy can affect a wide array of nerves. It is also associated with numerous underlying medical conditions and it has been reported to affect approximately 20 million individuals in the United States alone. While physical trauma, infection or exposure to toxins can cause neuropathy, diabetes has been considered to be the most common cause for neuropathy.
Causes of Neuropathy
Neuropathies are often inherited from birth or they develop later in life. The most frequent inherited neuropathy is the neurological disease Charcot-Marie-Tooth disease, which affects 1 in 2,500 people in the USA. Although�healthcare professionals are sometimes not able to pinpoint the exact reason for an acquired neuropathy, medically referred to as idiopathic neuropathy, there are many known causes for them, including: systemic diseases, physical trauma, infectious diseases and autoimmune disorders.
A systemic disease is one which affects the whole body. The most frequent systemic cause behind peripheral neuropathy is diabetes, which can lead to chronically high blood glucose levels that harm nerves.
A number of other systemic issues can cause neuropathy, including:
Kidney disorders, which permit high levels of nerve-damaging toxic chemicals to flow in the blood;
Toxins from exposure to heavy metals, including arsenic, lead, mercury, and thallium;
Certain drugs and/or medications, including anti-cancer medications, anticonvulsants, antivirals, and antibiotics;
Chemical imbalances because of liver ailments;
Hormonal diseases, including hyperthyroidism, which disturbs metabolic processes, potentially inducing cells and body parts to exert pressure on the nerves;
Deficiencies in vitamins, such as E, B1 (thiamine), B6 (pyridoxine), B12, and niacin, that can be vital for healthy nerves;
Alcohol abuse, which induces vitamin deficiencies and might also directly harm nerves;
Cancers and tumors that exert damaging pressure on nerve fibers and pathways;
Chronic inflammation, which can damage protective tissues around nerves, which makes them more vulnerable to compression or vulnerable to getting inflamed and swollen; and
Blood diseases and blood vessel damage, which may damage or injure nerve tissue by decreasing the available oxygen supply.
Additionally, if a nerve suffers from isolated bodily injury, it can become damaged, resulting in neuropathy. Nerves may suffer a direct blow that severs, crushes, compresses, or stretching them, even to the point of detaching them from the spinal cord. Common causes for these injuries are automobile accidents, falls, and sports injuries.
Nerve damage can also arise from powerful pressure on a nerve, like from broken bones and poorly fitted casts. Prolonged pressure on a nerve can also cause neuropathy, as in carpal tunnel syndrome, which occurs when the median nerve at the wrist becomes pinched. Also, persistent physical stress could inflame muscles, tendons, and ligaments, placing substantial pressure on the nerves.
Numerous infections from bacteria and viruses can lead to neuropathy by attacking nerve tissues directly or indirectly, for instance:
HIV
Shingles
Epstein-Barr virus
Lyme disease
Diphtheria
Leprosy
In addition, various autoimmune disorders, in which the body’s immune system attacks and destroys body tissue that is healthy, may result in nerve damage, including:
Peripheral neuropathy may result in several complications, as a result of disease or its symptoms. Numbness from the ailment can allow you to be less vulnerable to temperatures and pain, making you more likely to suffer from burns and serious wounds. The lack of sensations in the feet, for instance, can make you more prone to developing infections from minor traumatic accidents, particularly for diabetics, who heal more slowly than other people, including foot ulcers and gangrene.
Furthermore, muscle atrophy may cause you to develop particular physical disfigurements, such as pes cavus, a condition marked by an abnormally high foot arch, and claw-like deformities in the feet and palms.

Abstract Objective: The purpose of this case report is to describe a patient with chronic, multisite muscle fasciculations who presented to a chiropractic teaching clinic and was treated with dietary modifications.
Clinical features: A 28-year-old man had muscle fasciculations of 2 years. The fasciculations began in his eye and progressed to the lips and lower extremities. In addition, he had gastrointestinal distress and fatigue. The patient was previously diagnosed as having wheat allergy at the age of 24 but was not compliant with a gluten-free diet at that time. Food sensitivity testing revealed immunoglobulin G�based sensitivity to multiple foods, including many different grains and dairy products. The working diagnosis was gluten neuropathy.
Intervention and outcome: Within 6 months of complying with dietary restrictions based on the sensitivity testing, the patient�s muscle fasciculations completely resolved. The other complaints of brain fog, fatigue, and gastrointestinal distress also improved.
Conclusions: This report describes improvement in chronic, widespread muscle fasciculations and various other systemic symptoms with dietary changes. There is strong suspicion that this case represents one of gluten neuropathy, although testing for celiac disease specifically was not performed.
Introduction:�Muscle Fasciculations
There are 3 known types of negative reactions to wheat proteins, collectively known as wheat protein reactivity: wheat allergy (WA), gluten sensitivity (GS),�and celiac disease (CD). Of the 3, only CD is known to involve autoimmune reactivity, generation of antibodies, and intestinal mucosal damage. Wheat allergy involves the release of histamine by way of immunoglobulin (Ig) E cross-linking with gluten peptides and presents within hours after ingestion of wheat proteins. Gluten sensitivity is considered to be a diagnosis of exclusion; sufferers improve symptomatically with a gluten-free diet (GFD) but do not express antibodies or IgE reactivity.1
The reported prevalence of WA is variable. Prevalence ranges from 0.4% to 9% of the population.2,3 The prevalence of GS is somewhat difficult to determine, as it does not have a standard definition and is a diagnosis of exclusion. Gluten sensitivity prevalence of 0.55% is based on National Health and Nutrition Examination Survey data from 2009 to 2010.4 In a 2011 study, a GS prevalence of 10% was reported in the US population.5 In contrast to the above 2 examples, CD is well defined. A 2012 study examining serum samples from 7798 patients in the National Health and Nutrition Examination Survey database from 2009 to 2010 found an overall prevalence of 0.71% in the United States.6
Neurologic manifestations associated with negative reactions to wheat proteins have been well documented. As early as 1908, �peripheral neuritis� was thought to be associated with CD.7 A review of all published studies on this topic from 1964 to 2000 indicated that the most common neurologic manifestations associated with GS were ataxia (35%), peripheral neuropathy (35%), and myopathy (16%). 8 Headaches, paresthesia, hyporeflexia, weakness, and vibratory sense reduction were reported to be more prevalent in CD patients vs controls.9 These same symptoms were more prevalent in CD patients who did not strictly follow a GFD vs those who were compliant with GFD.
At present, there are no case reports describing the chiropractic management of patient with gluten neuropathy. Therefore, the purpose of this case study is to describe a patient presentation of suspected gluten neuropathy and a treatment protocol using dietary modifications.
Case Report
A 28-year-old man presented to a chiropractic teaching clinic with complaints of constant muscle fasciculations of 2 years� duration. The muscle fasciculations originally started in the left eye and remained there for about 6 months. The patient then noticed that the fasciculations began to move to other areas of his body. They first moved into the right eye, followed by the lips,�and then to the calves, quadriceps, and gluteus muscles. The twitching would sometimes occur in a single muscle or may involve all of the above muscles simultaneously. Along with the twitches, he reports a constant �buzzing� or �crawling� feeling in his legs. There was no point during the day or night when the twitches ceased.
The patient originally attributed the muscle twitching to caffeine intake (20 oz of coffee a day) and stress from school. The patient denies the use of illicit drugs, tobacco, or any prescription medication but does drink alcohol (mainly beer) in moderation. The patient ate a diet high in meats, fruits, vegetables, and pasta. Eight months after the initial fasciculations began, the patient began to experience gastrointestinal (GI) distress. Symptoms included constipation and bloating after meals. He also began to experience what he describes as �brain fog,� a lack of concentration, and a general feeling of fatigue. The patient noticed that when the muscle fasciculations were at their worst, his GI symptoms correspondingly worsened. At this point, the patient put himself on a strict GFD; and within 2 months, the symptoms began to alleviate but never completely ceased. The GI symptoms improved, but he still experienced bloating. The patient�s diet consisted mostly of meats, fruit, vegetables, gluten-free grains, eggs, and dairy.
At the age of 24, the patient was diagnosed with WA after seeing his physician for allergies. Serum testing revealed elevated IgE antibodies against wheat, and the patient was advised to adhere to a strict GFD. The patient admits to not following a GFD until his fasciculations peaked in December 2011. In July of 2012, blood work was evaluated for levels of creatine kinase, creatine kinase�MB, and lactate dehydrogenase to investigate possible muscle breakdown. All values were within normal limits. In September of 2012, the patient under- went food allergy testing once again (US Biotek, Seattle, WA). Severely elevated IgG antibody levels were found against cow�s milk, whey, chicken egg white, duck egg white, chicken egg yolk, duck egg yolk, barley, wheat gliadin, wheat gluten, rye, spelt, and whole wheat (Table 1). Given the results of the food allergy panel, the patient was recommended to remove this list of foods from his diet. Within 6 months of complying with the dietary changes, the patient�s muscle fasciculations completely resolved. The patient also experienced much less GI distress, fatigue, and lack of concentration.
Discussion
The authors could not find any published case studies related to a presentation such as the one�described here. We believe this is a unique presentation of wheat protein reactivity and thereby represents a contribution to the body of knowledge in this field.
This case illustrates an unusual presentation of a widespread sensorimotor neuropathy that seemed to respond to dietary changes. Although this presentation is consistent with gluten neuropathy, a diagnosis of CD was not investigated. Given the patient had both GI and neurologic symptoms, the likelihood of gluten neuropathy is very high.
There are 3 forms of wheat protein reactivity. Because there was confirmation of WA and GS, it was decided that testing for CD was unnecessary. The treatment for all 3 forms is identical: GFD.
The pathophysiology of gluten neuropathy is a topic that needs further investigation. Most authors agree it involves an immunologic mechanism, possibly a direct or indirect neurotoxic effect of antigliadin anti- bodies. 9,10 Briani et al 11 found antibodies against ganglionic and/or muscle acetylcholine receptors in 6 of 70 CD patients. Alaedini et al12 found anti-ganglioside antibody positivity in 6 of 27 CD patients and proposed that the presence of these antibodies may be linked to gluten neuropathy.
It should also be noted that both dairy and eggs showed high responses on the food sensitivity panel. After reviewing the literature, no studies could be located linking either food with neuromuscular symp- toms consistent with the ones presented here. There- fore, it is unlikely that a food other than gluten was responsible for the muscle fasciculations described in this case. The other symptoms described (fatigue, brain fog, GI distress) certainly may be associated with any number of food allergies/sensitivities.
Limitations
One limitation in this case is the failure to confirm CD. All symptoms and responses to dietary change point to this as a likely possibility, but we cannot confirm this diagnosis. It is also possible that the�symptomatic response was not due directly to dietary change but some other unknown variable. Sensitivity to foods other than gluten was documented, including reactions to dairy and eggs. These food sensitivities may have contributed to some of the symptoms present in this case. As is the nature of case reports, these results cannot necessarily be generalized to other patients with similar symptoms.
Conclusion:�Muscle Fasciculations
This report describes improvement in chronic, widespread muscle fasciculations and various other systemic symptoms with dietary change. There is strong suspicion that this case represents one of gluten neuropathy, although testing for CD specifically was not performed.

Etiology
There are 3 known types of negative reactions to wheat proteins, collectively known as wheat protein reactivity: wheat allergy (WA), gluten sensitivity (GS),�and celiac disease (CD). Of the 3, only CD is known to involve autoimmune reactivity, generation of antibodies, and intestinal mucosal damage. Wheat allergy involves the release of histamine by way of immunoglobulin (Ig) E cross-linking with gluten peptides and presents within hours after ingestion of wheat proteins. Gluten sensitivity is considered to be a diagnosis of exclusion; sufferers improve symptomatically with a gluten-free diet (GFD) but do not express antibodies or IgE reactivity.1
A 28-year-old man presented to a chiropractic teaching clinic with complaints of constant muscle fasciculations of 2 years� duration. The muscle fasciculations originally started in the left eye and remained there for about 6 months. The patient then noticed that the fasciculations began to move to other areas of his body. They first moved into the right eye, followed by the lips,�and then to the calves, quadriceps, and gluteus muscles. The twitching would sometimes occur in a single muscle or may involve all of the above muscles simultaneously. Along with the twitches, he reports a constant �buzzing� or �crawling� feeling in his legs. There was no point during the day or night when the twitches ceased.
Discussion
The authors could not find any published case studies related to a presentation such as the one�described here. We believe this is a unique presentation of wheat protein reactivity and thereby represents a contribution to the body of knowledge in this field.
This report describes improvement in chronic, widespread muscle fasciculations and various other systemic symptoms with dietary change. There is strong suspicion that this case represents one of
