Effects of Hip Bump Manipulation Versus Sham Treatment on Hip Internal Rotation, External Rotator Strength, and Bipodal Landing in Healthy Adults Aged 18-45: A Single-Blinded Randomized Controlled Trial

Summary

The purpose of this study is to objectively assess the effects of hip bump manipulation (HBM) on a healthy population aged 18-45 years. We hypothesize that the HBM will improve hip internal rotation passive range of motion, improve the strength of the hip external rotators, decrease compensatory motions in hip flexion during active range of motion, and improve bipodal landing mechanics. Human participants will be analyzed to determine whether the manipulation produces the intended clinical outcomes. While clinicians commonly use this technique, its effectiveness has yet to be substantiated through research. This technique is a high velocity low amplitude thrust to the greater trochanter which theorizes the quick stretch of the external rotator muscles and may improve a malpositioned femoral head within the acetabulum. These improvements may positively affect functional movements such as bipodal landing.
