Effect of Myofascial Release Technique on Lumbar Fascia Thickness and Low Back Pain: A Clinical Trial

Introduction: This study aims to evaluate the effect of lumbar myofascial release (MFR) technique on pain and thickness of the lumbar fascia tissue in patients with non-specific low back pain. Materials and Methods: In this clinical trial, 20 subjects with non-specific low back pain were treated by MFR on the lumbar region at 4 sessions. Low back pain severity and thickness of the lumbar fascia tissue were assessed by ultrasonographic imaging before and after the intervention. Results: Subjects showed significant reduction in lumbar fascia thickness (P=0.000) and low back pain severity (P=0.000). Conclusion: The lumbar MFR technique is effective in patients with non-specific low back pain due to reducing the lumbar fascia thickness and low back pain.
