Mobility & Flexibility

Back Clinic Mobility & Flexibility: The human body retains a natural level to ensure all its structures are functioning properly. The bones, muscles, ligaments, tendons, and other tissues work together to allow a range of movement and maintaining proper fitness and balanced nutrition can help keep the body functioning properly. Great mobility means executing functional movements with no restrictions in the range of motion (ROM).

Remember that flexibility is a mobility component, but extreme flexibility really is not required to perform functional movements. A flexible person can have core strength, balance, or coordination but cannot perform the same functional movements as a person with great mobility. According to Dr. Alex Jimenez’s compilation of articles on mobility and flexibility, individuals who don’t stretch their body often can experience shortened or stiffened muscles, decreasing their ability to move effectively.


Knee Complaints: Diagnostic Imaging Approach & Neoplasms

Knee Complaints: Diagnostic Imaging Approach & Neoplasms

Bone Neoplasms Tumor-Like Conditions

  • Bone neoplasms and tumor-like conditions affecting the knee can be benign or malignant. Age at Dx is crucial for DDx
  • In patients <40: Benign bone neoplasms: Osteochondroma, Enchondroma are relatively frequent
  • Fibrous cortical defect (FCD) & Non-ossifying fibroma (NOF) are particularly frequent in children
  • Giant cell tumor (GCT) is the m/c benign neoplasm of the knee in patients between 20-40 years of age
  • Malignant bone neoplasms in <40: m/c Osteosarcoma and 2nd m/c Ewing sarcoma
  • In patients >40: malignant neoplasms: m/c are secondaries d/t bone metastasis. Primary bone malignancy:�the m/c
  • Multiple Myeloma (MM). Less frequently:�a 2nd�peak of Osteosarcoma (post-radiation or Paget�s), Fibrosarcoma or Malignant�Fibrous�Histiocytoma�(MFH) of bone.
  • Clinically: knee pain, pathological fracture
  • Some tumor-like conditions like FCD/Non-ossifying fibroma are asymptomatic and may regress spontaneously. Occasionally NOF may present with pathologic fracture. N.B. any knee/bone pain in a child/adolescents should be�treated with clinical suspicion and adequately investigated.
  • Imaging: 1st step: radiography
  • MRI with T1+C is crucial for lesion characterization/regional extent, staging and pre-operative planning. CT may�help with pathologic Fxs detection. If malignant bone neoplasms considered, CXR/CT, PET-CT to investigate�metastatic spread and staging are important

Imaging Approach Bone Neoplasms

  • Approach to imaging Dx of bone neoplasms includes age, bone location (epiphysis vs. metaphysis vs. diaphysis), zone of transition surrounding the lesion, periosteal response, type of matrix, permeating or moth-eaten destruction vs. sclerotic, ground-glass, osteoid, cartilaginous matrix, soft tissue invasion, etc.
  • Key x-radiography features to DDx benign vs. malignant bone neoplasm:
  • Zone of transition: lesion is geographic with a narrow zone of transition vs. ill-defined wide zone of transition suggesting aggressive bone resorption
  • What type of bone destruction occurred: soap-bubbly appearance vs. osteolytic vs. osteosclerotic changes
  • Is there a round-glass matrix? Is there a well-defined rim of the sclerotic border with septations potentially suggesting slow growth and encapsulation like most benign processes.
  • Periosteal proliferation: solid vs. aggressive spiculated/sunburst/hair-on-end with local soft tissue invasion and Codman triangle (study next slide)

FCD & NOF

knee pain chiropractic treatment el paso tx.
  • FCD & NOF or more appropriately Fibroxanthoma of the bone are benign bone processes that m/c seen in children. DDx based on the size with FCD presenting as <3-cm and NOF >3cm lesion composed of a fibrous heterogeneous matrix. FCD are asymptomatic and may regress in many cases. Some may progress to NOF. Location: identified in the knee region as an eccentric cortical based lesion.
  • FCD must be DDx from an avulsive irregularity d/t repeated stress along Linea aspera by extensors muscles
  • Dx: radiography
  • Management: leave-me-alone lesion. Occasionally NOF may progress and lead to pathologic fracture requiring orthopedic consult

Osteochondroma

knee pain chiropractic treatment el paso tx.
  • Osteochondroma: m/c benign bone neoplasm. Knee is the m/c location. Contains all bone elements with a cartilaginous cap. Presented as pedunculated or sessile bone exostosis pointing away from the joint.
  • 1% malignant degeneration to chondrosarcoma if solitary lesion and 10-15% in cases of HME
  • Other complications: fracture (top left image) pseudoaneurysm of the Popliteal artery, adventitious bursa formation
  • Hereditary Multiple Exostosis (HME)– autosomal dominant process. Presents with multiple osteochondromas (sessile-type dominates). May lead to limb deformities (Madelung deformity, coxa valga) reactive ST pressure, malignant degeneration
  • Dx: radiography, MRI helps to Dx malignant degeneration to chondrosarcoma by changes in size and activity of cartilaginous cap (>2-cm in adults may manifest malignant degeneration). MRI will also help with Dx of regional complications

HME & Knee Pain

37-y.o male with HME and knee pain. Axial T1, T2 and STIR MRI slices at the popliteal region. Large cartilaginous cap and possible compression of the popliteal artery by osteochondroma. MRA was performed to evaluate popliteal A. pseudoaneurysm (large arrow). Pathology specimen obtained from the cartilaginous cap showed increased cellularity suggestive of malignant degeneration. Operative care was planned

Giant Cell Tumor (GCT) aka Osteoclastoma

knee pain chiropractic treatment el paso tx.
  • GCT- is a relatively common primary benign bone neoplasm. Age 25-40. M>F slightly.
  • M/C location: Distal femur>proximal tibia>distal radius>sacrum
  • GCT is the M/C benign sacral tumor. In 50% of cases, GCT occurs about the knee.
  • GCT is histologically benign, but lung Mets may develop esp. if in distal radius and hands, often termed Malignant GCT
  • <1% unresponsive/recurring GCTs may undergo malignant transformation to high-grade bone sarcoma
  • Pathology: histologically composed of osteoclasts-multinucleated giant cells with stromal cells derived from precursors monocyte-macrophage type. Produces cytokines and osteolytic enzymes. GCT may contain blood and associated with secondary Aneurysmal Bone Cyst (ABC)
  • Clinically: knee pain unresponsive to conservative care. Pathologic Fx may occur
  • Imaging: always begins with radiography followed by MRI and surgical biopsy that are crucial to Dx.
  • Rx: operative with curettage and cementing, a surgical appliance may be used if pathological fx present and cortical breach. In more severe cases other options available

Radiologic-Pathologic Dx

knee pain chiropractic treatment el paso tx.
  • Radiologic-pathologic Dx: osteolytic and soap-bubbly lesion typically involving metaphysis and into epiphysis (classic key feature) with subarticular extension. Zone of transition is generally narrow but occasionally in aggressive lesions wide zone of transition may be seen.
  • MRI: low T1, highT2/STIR, characteristic fluid-fluid levels noted that are present in GCT and ABC. Histology is crucial to Dx.
  • DDx: ABC, Brown cell tumor of HPT (osteoclastoma), Telangiectatic Osteosarcoma
  • Radiological rule: if the physeal growth plate is present Dx of GCT is taken off the list in favor of chondroblastoma and vice versa.

Primarily Soap-Bubbly Appearance of GCT

  • Osteoid forming a sclerotic mass with aggressive hair-on-end/speculated/sun-burst periosteal reaction, Codman’s triangle and soft tissue invasion. Order MRI for staging and extent. Chest CT is crucial for Lung Mets dx.

MRI is Crucial for Dx/Staging

knee pain chiropractic treatment el paso tx.
  • Note sagittal T1 (left) and STIR (right) MR slices: large mass extending from distal femoral metaphysis to remaining shaft. A low signal on T1 and high on STIR d/t marrow invasion with edema, hemorrhaging and tumor invasion. Local ST invasion seen (white arrows). Periosteal lifting and Codman�s triangle (green arrow) are additional signs of aggressive neoplasm.
  • Note an interesting feature that the epiphysis is spared d/t physeal plate serving temporarily as an additional barrier to the tumor spread.

Ewing Sarcoma

knee pain chiropractic treatment el paso tx.

Ewing sarcoma: age: 2-20, uncommon in black patients. 2nd m/c highly malignant bone neoplasm in children that typically arises from medullary cavity (Round cell tumors). Key symptom: bone pain that may mimic infection (ESR/CRP/WBC) Considered PNET Key Rad Dx: aggressive moth-eaten/permeative lucent lesions in the shaft of long bones with sizeable soft tissue invasion/typical onion skin periostitis. May produce saucerisation May affect flat bones. May appear as sclerotic in 33%. Early lung Mets (25-30%) bone-to-bone Mets Poor prognosis if delayed Dx.

M/C Malignant Knee Neoplasms in Adults

knee pain chiropractic treatment el paso tx.
  • 66-y.o. male with knee pain
  • Note aggressive expansile osteolytic lesion in the distal femur metaphysis into epiphysis. No periosteal reaction present. Following further work up with abdominal and chest CT scanning, Dx of Renal cell carcinoma was established
  • Distal Mets into lower extremity are more common with lung, renal cell, thyroid and breast CA.
  • Renal cell and Thyroid will typically present with aggressive osteolytic expansile mass aka �blowout Mets.�
  • In general, imaging approach should consist of Radiographic knee series, followed by MRI if x-rays are unrewarding
  • Tc99 Bone scintigraphy is the modality of choice to evaluate metastatic bone disease

Soft Tissue Neoplasms About the Knee

knee pain chiropractic treatment el paso tx.

Malignant fibrous histiocytoma (MFH) reclassified as Pleomorphic Undifferentiated Sarcoma (PUS) is the m/c S.T. sarcoma. MFH is aggressive biologically with poor prognosis M>F (1.2:1) 30-80 with a peak in a 6th decade. 25-40% of all adults sarcomas m/c extremities. Retroperitoneum next (worst prognosis d/t late Dx and large growth w/o symptoms) Clinically: painful, hard mass typically about the knee or thigh. Histology: poorly differentiated/undifferentiated malignant fibroblasts, myofibroblasts, and other mesenchymal cells Imaging: MRI is the modality of choice with T1, T2, T1+C. Typically appears as an aggressive heterogeneous mass intermediate to low signal on T1 and high signal on T2 with areas of necrosis and enhancement on T1+C. May appear misleadingly encapsulated w/o true capsule Management: operative with radiation and chemotherapy. Tumor depth is crucial for prognosis. 80% 5-year survival if <5cm deep in ST and 50% if >5-cm deep in ST.

Synovial Sarcoma

knee pain chiropractic treatment el paso tx.

Synovial sarcoma: common malignant ST neoplasm esp. in younger patients or older children/adolescents. M/C found in knee area Clinically: can present slowly as a palpable mass in the extremity often ignored d/t slow growth Imaging is the key: radiography may reveal ST. density/mass. Some synovial sarcomas may show calcification and mistaken for Myositis Ossificanse or heterotopic bone formation MRI with T1, T2 and T1+C are Dx modality of choice. Other modalities: US, CT are non-specific DDx: MFH Management: operative, chemo-radiation Prognosis: variable depending on size, invasion, metastasis

Knee Pain & Acute Trauma Diagnosis Imaging Part II | El Paso, TX

Meniscal Tears

knee pain acute trauma el paso tx.

 

  • Acute or chronic. Imaged with MRI (95% sensitivity & 81% specificity)
  • Menisci are formed by a composition of radial and circumferential collagen fibers (97% type 1) mixed with cartilage, proteoglycans, etc. 65-75% H2O
  • Aging can lead to meniscal attrition
  • Acute tears are d/t rotational and compressive forces, ACL deficient knees show greater chances of meniscal tears
  • Posterior horn of medial meniscus is m/c torn except in acute ACL tears when the lateral meniscus is m/c torn
  • The meniscus is well vascularized in children. In adults, 3-zones exist: inner, middle and outer (above bottom image)
  • Injury of the inner zone has no chance of healing
  • Injury of the outer zone (25% in total) has some healing/repair

Clinical Presentation

  • Pain, locking, swelling
  • Most sensitive physical sign: pain on palpation at the joint line
  • Tests: McMurry, Thessaly, Apply compression in prone
  • Management: conservative vs. operative depends on location, stability, patient’s age, and DJD and the type of tear
  • Partial meniscectomy is performed. 80% proper functions on follow up. Less favorable if >40-y.o and DJD
  • Total meniscectomy is not performed and only viewed historically. 70% OA 3-years after surgery 100% OA after 20 years post surgery.

Axial MR

knee pain acute trauma el paso tx.

 

  • Appearance the medial (blue) and the lateral meniscus (red)

Menisci Play Significant Role

knee pain acute trauma el paso tx.

 

Types Location & Stability

knee pain acute trauma el paso tx.

 

  • Types, location, and stability of tears are v. important during MRI Dx
  • Vertical/longitudinal tears especially occur in acute ACL tears. Some longitudinal tears found at the periphery or “red zone” may heal
  • Bucket handle tear: longitudinal tear in the inner edge that is deep and vertical extending through the long axis and may displace into a notch
  • Oblique/flap/parrot-beak are complex tears
  • Radial tear at 90-degree to plateau

Axial T2

knee pain acute trauma el paso tx.

 

  • Axial T2 WI fat-sat and coronal STIR slices of the posterior horn of the medial meniscus.
  • Note a radial tear of the posterior horn of the medial meniscus near the meniscal root. This is potentially an unstable lesion requiring operative care
  • The meniscus, in this case, is unable to provide a “hoop-stress mechanism.”

MRI Slices Coronal & Sagittal

knee pain acute trauma el paso tx.

 

  • Fat-sat coronal and sagittal proton density MRI slices revealing horizontal (cleavage) tear that is more typical in the aged meniscus
  • In some cases, when this tear does not contain a radial component, it may partially heal obviating the need for operative care

T2 w GRE Sagittal MRI Slice

knee pain acute trauma el paso tx.

 

  • Complex tear with a horizontal oblique and radial component.
  • This type of tear is very unstable and in most cases may need operative care

Bucket Handle Tear

knee pain acute trauma el paso tx.

 

  • Bucket handle tear are m/c in the medial meniscus esp. with acute ACL and MCL tear
  • MRI signs; double PCL sign on sagittal slices
  • Absent “bow-tie” sign and others
  • Most cases require operative care

DDx From Meniscal Degeneration

knee pain acute trauma el paso tx.

 

  • Occasionally meniscal tears need to be DDx from meniscal degeneration which may also appear bright (high signal) on fluid-sensitive MRI
  • The simplest rule is that if there is a true meniscal tear aka Grade 3 lesion, it always reaches/extends to the tibial plateau surface

The Role of MSK Ultrasound (US) in Knee Examination

  • MSK US of the knee permits high resolution and dynamic imaging of primarily superficial anatomy (tendons, bursae, capsular ligaments)
  • MSK US cannot adequately evaluate cruciate ligaments and the menisci in their entirety
  • Thus MR imaging remains modality of choice

Potential Pathologies Successfully Evaluated by MSK US

  • Patellar tendionosis/patellar tendon rupture
  • Quadriceps tendon tear
  • Prepatellar bursitis
  • Infrapatellar bursitis
  • Pes Anserine bursitis
  • Popliteal cyst (Baker cyst)
  • Inflammation/joint effusion with synovial thickening and hyperemia can be imaged with US (e.g., RA) especially with the addition of color power Doppler

Patient Presented With Atraumatic Knee Pain & Swelling

knee pain acute trauma el paso tx.

 

  • Radiography revealed sizeable soft tissue density within the superficial pre-patella region along with mild-to-moderate OA
  • MSK US demonstrated large septated heterogeneous fluid collection with mild positive Doppler activity on the periphery indicating inflammation d/t Dx of Superficial pre-patella bursitis

Long Axis US Images

knee pain acute trauma el paso tx.

 

  • Note normal lateral meniscus and fibers of LCL (above bottom image) compared to
  • Horizontal degenerative cleavage tear along with protrusion of lateral meniscus and LCL bulging (above top image)
  • Major limitation: unable to visualize the entire meniscus and the ACL/PCL
  • MRI referral is suggested

Rupture of Distal Tendon of Quadriceps

knee pain acute trauma el paso tx.

 

  • Note rupture of distal tendon of the Quadriceps muscle presented as fiber separation and fluid (hypo to anechoic) fluid collection within the substance of the tendon
  • Advantages of MSK US over MRI to evaluate superficial structures:
  • Dynamic imaging
  • Availability
  • Cost-effective
  • Patient’s preparation
  • Disadvantages: limited depth of structures, inability to evaluated bone and cartilage, etc.

Osteochondral Knee Injuries (OI)

  • osteochondral knee injuries can occur in children 10-15 y.o presented as Osteochondritis Dissecance (OCD) and in mature skeleton m/c following hyperextension and rotation trauma, particularly in ACL tear.
  • OCD-typically develops from repeated forces in immature bone and affects m/c postero-lateral portion of the medial femoral condyle.
  • OI in mature bone occurs m/c during ACL tears mainly affecting so-called terminal sulcus of the lateral femoral condyle at the junction of the weight-bearing portion opposed to tibial plateau and the part articulating with the patella
  • Osteochondral injuries may potentially damage the articular cartilage causing secondary OA. Thus need to be evaluated surgically
  • Imaging plays an important role and should begin with radiography often followed by MR imaging and orthopedic referral.

OCD Knee

knee pain acute trauma el paso tx.

 

  • 95% associated with some trauma. Other etiology: ischemic bone necrosis especially in adults
  • Other common location for osteochondral injuries: elbow (capitellum), talus
  • 1st step: radiography may detect osteochondral fragment potentially attached or detached
  • Location: a posterior-lateral aspect of the medial femoral condyle. Tunnel (intercondylar notch) view is crucial
  • MRI: modality of choice >90% specificity and sensitivity. Crucial for further management. T1-low signal demarcating line with T2 high signal demarcating line that signifies detachment and unlikely healing. Refer to orthopedic surgeon
  • Management: stable lesion esp. in younger children>off weight-bearing-heals in 50-75%
  • Unstable lesion and older child or impending physeal closure>operative fixation.

Knee Trauma

 

Knee Pain & Acute Trauma Diagnosis Imaging Part I | El Paso, TX

Knee Pain & Acute Trauma Diagnosis Imaging Part I | El Paso, TX

Tibial Plateau Fractures

  • Impaction type fractures predominate
  • Result from valgus or varus stress with or w/o axial loading
  • Associated with periarticular soft tissues injury
  • High-stress injury m/c due to jumps falls and axial loading, often with the splitting of the tibial plateau. Men>women. Patients are in their 30s
  • Low impact or no trauma in patients with osteoporosis d/t insufficiency fractures
  • Impaction injury is more common with depression of tibial plateau. Women>men. Patients are in their 70s

Lateral Tibial Plateau Fractures More Common

  • Functional anatomy plays a significant role
  • 60% of weight bearing is by the medial plateau
  • The medial plateau is more concave
  • Lateral plateau is slightly higher and more convex. Valgus stress impacts lateral plateau.
  • Tibial plateau fractures considered intra-articular and prone to delayed healing, non-union, meniscal injury (m/c lateral) ACL tear, secondary OA. Other complications: compartment syndrome, vascular injury.
  • Management: operative in many cases especially if >3-mm step-off at the plateau
  • If medial plateau or bicondylar Fxs present, ORIF will be required.

Imaging Plays A Crucial Role

knee pain acute trauma el paso tx.

 

  • Begins with x-radiography. X-radiography may not reveal the complexity and extent of this injury.
  • CT scanning w/o contrast will further delineate fracture complexity and pre-operative planning
  • MR imaging may be considered to evaluate for internal derangement: meniscal, ACL injuries.
  • Shatzke classification may help to evaluate the complexity of this injury

Key Diagnostic Sign

knee pain acute trauma el paso tx.

 

  • AP and lateral horizontal beam (cross table) left knee radiograph. Note subtle depression of the lateral plateau manifested by the lateral plateau appearing at the same level or lower as the medial. A critical diagnostic sign is the presence of fat-blood-interphase or FBI sign on cross-table lateral (above arrow) indicating intra-articular knee fracture

Lipohemarthorosis aka FBI Sign

knee pain acute trauma el paso tx.

 

  • Can be detected by radiography, CT or MR imaging
  • FBI sign is a reliable secondary radiographic sign of intra-articular knee fractures, regardless of how small they are
  • Mechanism: fracture results with acute hemarthrosis
  • Hemarthrosis will also occur w/o Fx. However, Fx will result with a fatty marrow being released into the joint cavity. Fat is a less dense medium (lighter) and will appear on the top of the hemorrhage if the patient is held in the supine position for 5-10-minutes before the cross-table radiograph is taken
  • FBI sign confirms the intra-articular Fx.
  • ACL/PCL, meniscal tears will not result in FBI sign

Lateral Tibial Plateau Fx

knee pain acute trauma el paso tx.

 

  • Lateral tibial plateau Fx that was managed operatively
  • Most common complication: premature secondary OA
  • More complex injuries may result in more extensive operative care

Knee Internal Derangement

  • Acute or chronic injuries of meniscal fibrocartilages and ligamentous restraints
  • Tears of the ACL and posterior horn of the medial meniscus are the most common
  • Acute ACL tears, however, often result with a lateral meniscus tear
  • Acute ACL tear may occur as a combined injury of the ACL, MCL, and medial meniscus
  • Functional anatomy: ACL prevents anterior displacement of the tibia and secondary varus stress
  • MCL functions together with ACL in resisting external rotation of the tibia especially when the foot is planted (closed chain position)
  • MCL is firmly attached to the medial meniscus, explaining the classic triad of ACL, MCL and medial meniscal tear (O’Donahue terrible triad)
  • Cruciate ligaments (ACL/PCL) are intra-articular but extra-synovial. Less likely to be torn in closed pack position (full extension). When all articular facets of tibia and femur are in full contact, the ACL/PCL are at least tension and stable
  • When the knee is flexed 20-30-degrees or more ACL is taut and remains unstable
  • ACL is a significant mechanoreceptor that feeds the info to CNS about the joint position. Thus the majority of previous ACL tears will lead to some degree of knee instability

Functional Anatomy of ACL

knee pain acute trauma el paso tx.

Diagnosis of ACL Tear

knee pain acute trauma el paso tx.

 

  • Diagnosis of ACL tear requires MR imaging
  • Concerns exist of not only ligamentous injuries but injuries to the articular cartilage and menisci.
  • Most vendors will perform at least: one T1 WI in coronal or sagittal planes. Sagittal and coronal Proton-density slices to evaluate cartilaginous structures. Fast spin-echo sagittal, axial and coronal T2 fat-saturated or sagittal and coronal STIR images are crucial to demonstrate edema within the substance of knee ligaments
  • Note sagittal proton-density MRI slice showing intact ACL (above)
  • ACL is aligned along the Blumensaat line or oblique line corresponding the intercondylar roof of Femoral condyles. Lack of such alignment by the ACL is significant for ACL tear

Imaging Dx of Internal Derangement

knee pain acute trauma el paso tx.

 

  • MRI shows 78-100% sensitivity and 78-100% specificity
  • Primary signs of ACL tear: non-visualization of ACL (above green arrow), loss of its axis along the Blumensaat line (above triangle heads), wavy appearance and substance tear (above white arrow) or edema and cloud-like indistinctness (above yellow arrow)

Reliable Secondary Signs of ACL Tear

knee pain acute trauma el paso tx.

 

  • May be observed on the radiographs and MRI
  • Segond avulsion fracture (80% specificity for ACL tear) (next slide)
  • Deep femoral notch sign indicating osteochondral fracture (above bottom images) and
  • Pivot -shift bone marrow edema in the posterolateral tibial condyle d/t external rotation and often valgus impact by the lateral femoral condyles (above top image)

Segond Fracture (Avulsion by ITB)

knee pain acute trauma el paso tx.

 

  • Segond fracture at Gerdy’s tubercle. A vital sign of the ACL tear seen on both radiographs and MRI

Management of ACL Tears

knee pain acute trauma el paso tx.

 

  • In acute cases, usually operative using cadaveric or autograft (patella ligament or hamstring) ACL reconstruction
  • Complications: graft tear, instability and premature DJD, joint stiffness d/t lack of postoperative rehab or gaft shortening. More rare, infection, a formation of intraosseous synovial cysts, etc.

How Combining Chiropractic & Yoga Can Be Beneficial To Your Spine

How Combining Chiropractic & Yoga Can Be Beneficial To Your Spine

Yoga has long been touted as a healing activity that extends beyond its known fitness benefits. It can help alleviate depression, relieve stress, and decrease anxiety as well as tighten and tone the body.

A 2016 study by Yoga Alliance and Yoga Journal shows that the more than 20 million people who practice yoga spend more than $10 billion on related classes and products. Chiropractors have picked up on the benefits of yoga and are recommending it to their patients. Why, because it helps to improve flexibility as well as spinal health.

Chiropractic and the spine�s role in the body.

Chiropractic is primarily intended to align the spine and balance the body. The spine is the primary support for the body. It houses most of the central nervous system and provides pathways for neural impulses to move throughout the body.

When the spine is out of alignment, it can affect how the central nervous system functions. It can also affect flexibility and even overall mobility as well as cause pain and stiffness.

Chiropractic treatment brings the spine back into alignment. It helps to balance the body and treat injuries as well as help with the changes the aging body experiences.

One of the best-known uses for chiropractic is to treat pain. It is a medication free, non-invasive treatment for chronic pain, sports-related injuries, and even automobile accidents. Many patients had reported finding relief with chiropractic when nothing else worked.

Combining yoga with chiropractic increases the effectiveness of the treatment while strengthening the body and making it better able to respond to it. It is the perfect complement to chiropractic care, and many patients are discovering tremendous health benefits from this winning, healthy combination.

yoga and chiropractic el paso tx.

What is Yoga?

In its purest form, it is an ascetic and spiritual discipline that comes from Hindu culture. It involves simple meditation, conscious breathing or breath control, and performing certain body postures.

While an ancient practice long used for spiritual and emotional healing as well as physical wellness, yoga has been adopted in western culture and widely accepted as a form of fitness as well as a therapeutic practice used for relaxation and overall good health. It focuses on inward healing for outward results.

People who regularly practice find they are more centered, handle stress better, and aren�t as likely to experience depression and anxiety. They also are more flexible, have better mobility, and have stronger leaner bodies.

What happens when you combine yoga and chiropractic care?

Because yoga helps to lower blood pressure, decrease stress, and strengthen the body�s core, it is perfect therapy for the chiropractic patient. While chiropractic care is working to align the spine and balance the body, yoga is helping to strengthen the muscles surrounding the spine, providing better support. The numerous health benefits, particularly regarding blood flow and relaxation help to increase chiropractic�s effectiveness as a pain management tool.

Patients who combine yoga and chiropractic will also often find that they see the effects of both treatments much faster than they would if they were only doing one or the other. Both chiropractic and yoga help with balance, flexibility, and mobility, but they come at it from somewhat different approaches. The benefit of this is that it provides a more balanced, well-rounded treatment in these areas as one supports the other.

Yoga also tones and tightens the body, preparing it for much more profound levels of healing, cleansing and releasing the body of tensions that may have been held�in for years. It also works to stretch muscles that have been restricted for years, or even for the patient�s entire life. It prepares the body to accept the full benefits of chiropractic and respond faster and more thoroughly.

What Chiropractic Patients Want To Know About Pilates

What Chiropractic Patients Want To Know About Pilates

Everyone knows that exercise is great for overall wellness, better health, and a healthy body. Many chiropractors will often recommend regular exercise to their patients who need to lose weight, want better mobility, or are seeking relief from depression. Some chiropractors are turning to Pilates to help their patients get stronger, more flexible, and more mobile.

pilates exercise el paso tx.

What is Pilates?

In the early 20th century Joseph Pilates developed the exercise program to help World War I soldiers improve their physical fitness. It was used to rehabilitate patients who had been injured. By incorporating resistance, stretching, and target strengthening exercise, Pilates uses resistance bands, individual machines, and floor work to reshape and rehabilitate the body. Dancers, gymnasts, athletes, and celebrities use Pilates to stay in shape. However, anyone can do it for a healthier, more supple spine.

Care of the spine is at the core of Pilates. By keeping it in a neutral, or natural, position, this exercise can prevent back pain as well as help ease it. When done correctly, Pilates can:

  • Improve muscle control and movement efficiency through mental focus.
  • Make you more mindful of your body�s position, specifically, remaining aware of the spine�s position and keeping it neutral
  • Improve centering and mental focus through special, breathing techniques

There are four areas where you can incorporate movement into your workplace: policies, places, people, and permission.

Movement Policies

Create written policies that encourage and advocate movement during work hours. Incorporate moving workstations, moving meetings, flexible scheduling, more breaks when meetings run long, and a movement-friendly dress code.

Provide information and training to all employees and leadership underlining the importance of the policies and explaining the importance of movement as well as what they can do to support the initiative.

Places

Stretching With Muscle Or Joint Pain

Stretching With Muscle Or Joint Pain

Dealing with joint or muscle pain can be a daunting experience. It’s important to work on maintaining mobility and flexibility. The more flexible, the less likely to be injured. One of the best ways to improve flexibility is through stretching.

First and foremost is the need to warm up your muscles before stretching. Stretching first can actually cause injury by pushing the joints too far. Spend a few minutes doing some light activity before stretching. This can be a quick walk or some basic calisthenics.

A chiropractor can recommend stretches, or you can use some of these basic techniques. There are two basic forms of stretching, static and dynamic.

Static Stretching & Dynamic Stretching
