Influence of Hamstring Tightness on the Functions of Lumbar and Pelvic Regions among Sewing Machine Operators in a Garment Factory of Colombo District

Introduction: Clinical evidence suggests that hamstring tightness influences lumbar pelvic rhythm and shortened increase the risk of injury to spine. Objectives: To determine association with tilt in standing position, trunk, range motion during forward bending among sewing machine operators Methods: A descriptive cross-sectional study was conducted 169 aged 18-55 years using passive knee extension test, tri-goniometric method, finger floor test modified Schober measure tightness, tilt, trunk flexion flexion, respectively. Results: weak negative correlation between (r=-0.28; p=0.001). significant (r=0.47; Conclusions & Recommendations: Hamstring affects bending.
