Effectiveness of Pectineus Myofascial Release in Reducing Low Back Pain and Improving Function in Adults Aged 20-50: A Prospective Single-Arm Interventional Study

Background: Low back pain (LBP) affects 80% of adults, with hip flexor dysfunction like pectineus tightness contributing via pelvic misalignment. This study evaluated pectineus myofascial release (MFR) efficacy. Methods: Fifty adults (20-50 years) with nonspecific chronic LBP underwent six sessions of pectineus MFR over three weeks. Primary outcome: VAS pain difference of 3 points. Secondary: 50% Roland-Morris Questionnaire (RMQ) improvement. Assessments at baseline, mid (session 3), and end. Results: VAS reduced from 6.8±1.2 to 3.7±1.0 (Δ=3.1, p<0.001). RMQ improved 50.1% (14.2±3.1 to 7.1±2.2, p<0.001). No adverse events. Conclusion: Pectineus MFR provides clinically meaningful pain relief and functional gains in young adults with LBP.
