Background: Active Release Technique is a soft tissue method that focuses on relieving tissue tension via the removal of fibrosis and adhesions, which can develop in tissue as a result of overload due to its repetitive use. The Mulligan bent leg raise technique is used to improve the range of straight leg raises in subjects with low back pain or referred thigh pain and to improve the flexibility of the hamstring in individuals with hamstring tightness. Objective: To compare the effects of active release technique versus Mulligan bent leg raise in healthy individuals with hamstring tightness. Methods: This study was a quasi-experimental study with a sample size of 40 normal, healthy individuals aged between 18 to 25 years and normal healthy subjects free from any signs and symptoms of regional pathology, vascular insufficiency, low backache or radiculopathy. While exclusion criterion was any history of injury in the lower extremity in the past three months (upper and lower motor neuron lesions), participants must not be involved in gymnastics, sports activities, strength training, or yoga, and participants must not be taking any treatment of a musculoskeletal nature. Group A received a single session of the active release technique, and the other group B received that of the Mulligan bent leg raise. All the subjects were evaluated through the straight leg raise test and the popliteal angle through the active knee extension test as pre- and post-intervention measuring tools for hamstring tightness. Results: There was a significant difference between pre-values and post-values of popliteal angle (p<0.001) and passive straight leg raise test (p<0.001) between the active release technique group and the Mulligan bent leg raise group. The results also showed significant differences in popliteal angle and passive straight leg raise test post-interventional scores (p<0.001) within the groups. Conclusion: Both the active release technique and the Mulligan bent leg raise technique proved to be significant in improving hamstring tightness in healthy asymptomatic subjects in a single session, but active release technique proved to be more significant than the Mulligan bent leg raise in improving hamstring tightness immediately after the application of these comparative interventions.
