Immediate Effect of Active Release Technique versus Mulligan Bent Leg Raise in Subjects with Hamstring Tightness: a Randomized Clinical Trial

Background: To study and compare the effectiveness of active release technique and mulligan bent leg raise in subjects with hamstring tightness. Methods: 40 normal healthy subjects (20 in each group) were recruited in the study under simple randomization method. Group A received single session of Active Release Technique and Group B received single session of Mulligan Bent Leg Raise technique for hamstring tightness. Popliteal angle and Sit and reach flexibility tests were measured pre intervention and post intervention. Data was analyzed using t-test. Results: The group treated with Active release technique showed significant improvement in Popliteal angle (P<0.001) and sit and reach flexibility test (P<0.001) as compared to Mulligan bent leg raise technique. Results showed the significance difference within the groups post intervention. Conclusion: A single session of Active release technique is better as compared to Mulligan bent leg raise technique to improve hamstring flexibility and range of motion.
