Summary

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