ABSTRACT
Background: Hamstring tightness is prevalent among young adults in sedentary occupations, limiting range of motion, contributing to lumbar spine overload, and impairing physical function. While Active Release Technique (ART) and Dynamic Oscillating Stretching Technique (DOS) have individually shown effectiveness in improving hamstring flexibility, no study has directly compared their immediate effects.
Objective: To compare the immediate effect of ART and DOS on hamstring tightness in young adults.
Methodology: A quasi-experimental comparative study was conducted on 68 subjects (aged 20–40 years) with hamstring tightness, divided into two groups of 34. Group A received a single session of ART and Group B received a single session of DOS. Popliteal angle was measured pre- and post-intervention using a universal goniometer. Paired t-test and unpaired t-test were used for intragroup and intergroup analysis, respectively.
Results: Both groups showed statistically significant improvement post-intervention. Group A (ART) showed a mean reduction from 34.44° to 30.21° (t = 20.45, p < 0.0001) and Group B (DOS) from 34.82° to 29.68° (t = 12.24, p < 0.0001). Intergroup comparison revealed no significant difference between the two techniques (t = 0.52, p = 0.60).
Conclusion: Both ART and DOS are equally effective in producing an immediate improvement in hamstring flexibility in young adults, with no significant difference between them.
