Mulligan Techniques for Gait and Pelvic Motion in Short Hamstrings

Various stretching methods have been developed to reduce hamstring tightness and improve flexibility. Static stretching is one of the safest and most common methods used to increase muscle length; however, its effect is temporary and diminishes rapidly. Additionally, such conventional methods can be uncomfortable and require longer periods to yield visible results. Unlike other mobilization procedures, the Mulligan concept is performed while patients execute a resisted muscle contraction or move actively or passively. Distinct from many other manual therapy approaches, this technique is applied within a symptom-free range of motion, which likely enhances its safety. Traction Straight Leg Raise (TSLR) and Bent Leg Raise (BLR) techniques are specific interventions defined by Mulligan. There are limited studies in the literature investigating the effects of these two techniques on hamstring flexibility. However, no study has compared these two techniques in terms of spatiotemporal gait parameters and pelvic oscillations. Therefore, the purpose of this study is to compare the effects of BLR and TSLR techniques applied to individuals with hamstring tightness on hamstring flexibility, spatiotemporal parameters of gait, and pelvic oscillations.
