Sacroiliac joint hypermobility biomechanics and what it means for healthcare providers and patients.

PM R 2019 Apr 26. Epub 2019 Apr 26.

U.S. Spine & Sport Foundation, 3760 Convoy Street #101, San Diego, CA, 92111.

Sacroiliac joint dysfunction is complex with numerous etiologies. Proper stabilization of the sacroiliac joint allows for effective transfer of loads between the trunk and the lower extremities during static and dynamic activities, while maintaining a freely nutating motion. A loss of integrity of the stabilizing soft-tissue structures inhibits the ability to transmit axial loads and creates uneven stresses on the joint and surrounding tissues. Hypermobility of the sacroiliac joint can be due to ligamentous instability or secondary to adaptive biomechanical changes and increased stresses affecting the joints of the pelvis. This article examines the current evidence related to the loss of stability on sacroiliac joint pain and dysfunction. A review of exercise goals for the hypermobile joint is included. Level of Evidence: IV.

A Randomized Controlled Trial of Chiropractic Compared to Physical Therapy for Low Back Pain in Community Dwelling Geriatric Patients.

Top Integrative HealthCare, 2015:6(1)

Top Integrative HealthCare

Background: Chronic low back pain is the most frequently reported musculoskeletal condition in the elderly, affecting up to 50% of this age cohort. It is a leading falls related comorbidity and robust predictor of morbidity among the elderly. Methods: This analysis of a randomized controlled trial evaluated the use of either chiropractic care (CC) or physical therapy (PT) as a treatment for geriatric patients with balance problems and with or without chronic low back pain. Of the one hundred and eighteen participants enrolled, sixty one participants (51.7%) were randomized into the CC group and fifty seven participants (48.3%) into the PT group. A pain questionnaire was administered at baseline, after 6 weeks of treatment, and again at week 12. University ethics committee approval was obtained and written informed consent was given. Results: There was statistically significant reductions in pain for this intent-to-treat design mixed model analysis of variance (ANOVA) (p < 0.05) and Bonferroni correction (p < 0.025; 95% CI). The CC and PT groups had similar reductions at week 6 for Box 21 current pain scores (52.7%, 50.9%); Box 21 least pain scores (40.4%, 45.4%); Box 21 worst pain scores (42.1%, 37.2%); Box 21 usual pain scores (41.1%, 46.7%); and Box 21 number of days per week in pain scores (24.3%, 18.9%). There were no significant between group effects. Conclusion: There were statistically and clinically significant improvements in pain outcome measures in both the chiropractic care and physical therapy treatment groups at week six and at week twelve.

Neurogenic thoracic outlet syndrome, a clinical brief

Top Integrative HealthCare, 2013; 4: 3

Top Integrative HealthCare

Thoracic outlet syndrome (TOS) is a frequently overlooked and misunderstood syndrome which is most often of neurogenic origin. A thorough clinical examination is essential in properly diagnosing TOS, differentiating neurogenic TOS from vascular (arterial or venous) TOS, and effectively managing patients suffering from this condition.

Pelvic entrapment neuropathies in the disc patient that is refractory to care.

SpineLine 2012, Nov-Dec; 13:6; 32.

SpineLine

Entrapment neuropathies of the sciatic and femoral nerves arising from anatomical variations in the piriformis muscle and iliopsoas muscle complex should be considered in the differential for the disc patient who is refractory to care. The piercing and dividing of the piriformis muscle by the sciatic nerve has a reported prevalence of 16.9% while splitting of the femoral nerve by the iliopsoas complex of muscles has been reported in 7.9% of cadavers studied.1 These variants have the potential to produce neural irritation and simulate lumbar radiculopathy. The clinical significance of a combined peripheral nerve and muscular variant may not be immediately obvious in the patient with suspected disc involvement; however, consideration should be given to the presence of a pelvic entrapment neuropathy. Bilateral latency and amplitude differences in nerve conduction velocity testing will localize the femoral nerve distribution, while electromyographic evaluation of the level of axonal loss combined with enhanced signal intensity of the nerves during T2-weighted neurography suggests that the lumbar disc radiculopathy is actually due to a peripheral nerve entrapment.

Methodology of a Randomized Controlled Trial of Manipulation and Physical Therapy for Chronic Low Back Pain and Balance Problems in the Geriatric Population

Top Integrative HealthCare, 2011; 2(4).

Top Integrative HealthCare

Introduction: Postural control problems are one of the most common conditions affecting the geriatric population. This paper discusses the design of a prospective randomized controlled trial that examines a mixed modal treatment protocol for geriatric patients with non-vestibular related balance problems with or without chronic low back pain. Methods: This three-year study will randomly assign a total of 300 consecutive community dwelling subjects between the ages of 65 and 80 years old into treatment groups receiving 6 weeks of either physical therapy or chiropractic care. Primary outcomes for balance include the NeuroCom balance tests, Berg Balance Scale, and POMA. The primary outcomes for low back pain are the VAS and 21-point box scale. Secondary outcomes are the Timed Up and Go Test for mobility and the Falls Efficacy Scale for confidence in performing everyday activities. Participants will be tested prior to randomization, and after 6 weeks of treatment, and again 6 weeks later. The data analysis for this intent-to-treat design will be mixed-model analysis of variance (ANOVA) with an alpha level of 0.05 for statistical significance for each outcome measure. Conclusion: The methodology and design of a multimodal treatment protocol for balance disorders and low back pain in the geriatric population is described in this paper. By examining geriatric patients in separate cohorts with or without cLBP, we hope to identify effective treatment protocols and further define the relative contribution of cLBP to balance problems.

Balance Problems in the Geriatric Patient, an interdisciplinary grand round.

Top Integrative Health Care, 2011; 2(1).

Top Integrative Health Care

Balance problems and falls are common among the elderly and are a leading cause of institutionalization in this group. Low back pain (LBP) is the most frequently reported musculoskeletal condition in the elderly and is a leading comorbid factor directly linked to the incidence of falls. Balance disorders in the geriatric population are often a multifactorial condition. While there is not a single solution to postural control problems, there is evidence that the most effective treatment strategies for balance disorders consist of a multimodal approach including a re-evaluation of medications, manual therapy, exercise, and behavioral modification programs. This case report describes an interdisciplinary approach to the diagnosis and management of an 85 year old woman with balance problems.

Management of acute patellar dislocations, an international case report.

J Chiropr Med, 2015

J Chiropr Med.

Introduction: The purpose of this case study is to describe the evaluation and management of patellar dislocations. Clinical features: Acute lateral patellar dislocations are a common orthopedic condition that occurs when the confinement of the patella is disrupted from the patella-femoral groove often damaging the medial patellofemoral ligament. This condition has a high incidence of reoccurrence, is most common in adolescent females and athletes and has certain familial tendencies. A case study of an individual who dislocated their left patella while traveling abroad and the subsequent care received in Thailand, China, and the United States is included. Intervention and outcomes: Lateral dislocation of the patella has the potential for damage to the medial patellofemoral ligament and osteochondral fractures. The presence of large amounts of sub-patellar effusion may indicate the need for advanced imaging to rule out fracture. Non-operative treatment protocols including manual closed reduction of the patella, casting or splinting of the leg and rehabilitation exercises are most often employed in cases without osteochondral fracture. Patients without hemarthrosis or displaced osteochondral fragments that receive proper treatment can typically expect a full return to activity within 8-12 weeks from the time of injury. Conclusion: Acute patellar dislocations are a common orthopedic injury. When presenting without fracture, these injuries respond well to conservative treatments.
