Abstract
Background: Hamstring tightness is a common musculoskeletal problem among college students, mainly due to prolonged sitting, poor posture, and reduced physical activity. Reduced hamstring flexibility may impair pelvic alignment, alter lower-limb biomechanics, and increase the risk of low back pain and lower-extremity injuries. Dynamic Soft Tissue Mobilization (DSTM) and Mulligan’s Bent Leg Raise (BLR) technique are used to improve hamstring flexibility; however, evidence directly comparing their effectiveness remains limited.
Objective: To compare the effectiveness of Dynamic Soft Tissue Mobilization and Mulligan’s Bent Leg Raise technique in improving hamstring flexibility among college students with hamstring tightness.
Methods: A comparative study was conducted among 30 college students aged 17–25 years with hamstring tightness. Participants were allocated into two groups of 15 using convenience sampling. Group A received Dynamic Soft Tissue Mobilization, while Group B received Mulligan’s Bent Leg Raise technique. Both groups underwent three sessions per week for four weeks. Hamstring flexibility was assessed before and after treatment using the Active Knee Extension Test (AKET). Statistical analysis used paired and independent t-tests, with significance set at p<0.05.
Results: Both groups demonstrated statistically significant improvements in hamstring flexibility after the intervention (p ≤ 0.05). Between-group comparison showed no statistically significant difference in post-intervention outcomes for the right limb (p = 0.746) or left limb (p = 0.478), indicating comparable effectiveness.
Conclusion: Within the limitations of this study, both Dynamic Soft Tissue Mobilization and Mulligan’s Bent Leg Raise technique significantly improved hamstring flexibility, with no statistically significant difference between interventions.
