Hip bump manipulation compared with sham for hip rotation, strength, and landing mechanics in healthy adults
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
This project will try a quick high-velocity hip bump manipulation to see if it improves hip internal rotation, hip external rotator strength, and bipodal landing mechanics in healthy adults aged 18–45.

What this trial studies
Healthy adults aged 18–45 without hip or recent lower-extremity pathology will receive either a high-velocity low-amplitude hip bump manipulation applied to the greater trochanter or a sham/no-treatment condition. Investigators will measure passive hip internal rotation range of motion, hip external rotator strength, EMG activation patterns, and bipodal landing mechanics before and after the intervention. The technique is theorized to produce a rapid stretch of external rotator muscles and potentially alter femoral head position in the acetabulum, which could change movement patterns. While clinicians commonly use this maneuver, its effects on objective biomechanical and neuromuscular outcomes remain not well substantiated.
Who should consider this trial
Good fit: Healthy adults aged 18–45 without hip or pelvic pain, recent lower-extremity injury, low back pain within six months, diagnosed hip joint disease, scoliosis, prior femoroacetabular surgery, or adhesive allergies are the ideal candidates.
Not a fit: People with diagnosed hip osteoarthritis or labral tears, recent low back or lower-extremity injuries, scoliosis, prior hip surgery, or known allergic reactions to EMG adhesives are unlikely to qualify and may not benefit.
Why it matters
Potential benefit: If successful, the maneuver could offer a simple manual approach to increase hip internal rotation and strength and reduce compensatory movements during landing, potentially lowering injury risk or improving function.
How similar studies have performed: Although high-velocity low-amplitude manipulations are commonly used in practice, there is limited published evidence specifically supporting hip bump manipulation for these biomechanical and neuromuscular outcomes, so this application is relatively untested.
