Study of Hip Bump Manipulation Compared to Sham Treatment to Improve Hip Movement and Strength in Healthy Adults Aged 18 to 45

What this Trial Is About

Researchers are studying the effects of hip bump manipulation HBM on healthy adults aged 18 to 45 years. The study aims to determine if HBM can improve hip internal rotation, increase the strength of hip external rotator muscles, reduce compensatory movements during hip flexion, and enhance landing mechanics. Although clinicians often use this high velocity low amplitude thrust technique, its benefits have not yet been proven through research. Participants will be randomly assigned to one of two groups one receiving the hip bump manipulation targeting the greater trochanter, and the other receiving a sham manipulation at the iliac crest. Both procedures are performed in a single session lasting about 20 minutes. This single-blinded trial compares the clinical outcomes between the active and sham groups. During the study visit, participants will undergo assessments before and after the intervention, including measures of hip external rotation strength, hip internal rotation range of motion, muscle activation via EMG, and bipodal landing mechanics. Additional measures include hip deviation with assisted hip flexion and external rotation range of motion. The entire evaluation occurs within one session, and the study concludes after these assessments.
