Effect of Remote Myofascial Release on Lumbar Elasticity and Pain in Patients With Chronic Nonspecific Low Back Pain: A Randomized Clinical Trial

Objective: The purpose of this study was to evaluate the effects of myofascial release technique of a remote area on lumbar elasticity and low back pain (LBP) in patients with chronic nonspecific LBP. Methods: For this clinical trial, 32 participants with nonspecific LBP were assigned to a myofascial release group (n = 16) or a remote release group (n = 16). Participants in the myofascial release group received 4 sessions of myofascial release to the lumbar region. The remote release group received 4 myofascial release sessions to the crural and hamstring fascia of the lower limbs. Low back pain severity and elastic modulus of the lumbar myofascial tissue were assessed before and after treatment by the Numeric Pain Scale and ultrasonography examinations. Results: The mean pain and elastic coefficient in each group before and after myofascial release interventions were significantly different (P = .0005). The results showed that the changes in mean pain and elastic coefficient of the 2 groups after myofascial release interventions were not significantly different from each other (F ([1-22] )= 1.48, P = .230, 95% confidence interval) (effect size = 0.22). Conclusion: The improvements in the outcome measures for both groups suggest that remote myofascial release was effective in patients with chronic nonspecific LBP. The remote myofascial release of the lower limbs reduced the elastic modulus of the lumbar fascia and LBP. (J Chiropr Med 2023;22;52-59)
