Influence of Hamstring Tightness on the Functions of Lumbar and Pelvic Regions among Sewing Machine Operators in a Garment Factory of Colombo District
Abstract
Introduction: Clinical evidence suggests that hamstring tightness influences lumbar pelvic rhythm and shortened hamstring increase the risk of injury to the spine.
Objectives: 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
Methods: 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.
Results: 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).
Conclusions & Recommendations: Hamstring tightness affects the lumbar and trunk range of motion during forward bending.
