Brief 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.

Outcome Measures
Primary Outcomes (4)
Hip External Rotation Strength
Measured with ActivForce Handheld Dynamometry. 3 trials for an average Mean Voluntary Isometric Contraction
"From pre-intervention to post-intervention within a single session lasting approximately 20 minutes."
Hip Internal Rotation Range of Motion
Hip Internal rotation measured in a seat position 90/90 position. Measured with IPhone Digital Goniometry. 3 trials with a calculated average
"From pre-intervention to post-intervention within a single session lasting approximately 20 minutes."
Hip EMG Muscle Activation
Delsys Trigno Wireless System will be used to monitor changes in muscle activation between the Tensor Fascia Latae, Gluteus Medius, and Gluteus Maximus. During seated isometric external rotation contraction and bipodal landing. EMG will be retrieved on the 2nd attempt out of 3 trials.
"From pre-intervention to post-intervention within a single session lasting approximately 20 minutes."
Bipodal Landing
Kinvent K-Delta Force Plates used to measure changes in bipodal landing mechanics including force distribution, time to stabilization, etc. 3 trials will be conducted to present average values
"From pre-intervention to post-intervention within a single session lasting approximately 20 minutes."
Secondary Outcomes (2)
Hip Deviation with Active Assisted Hip Flexion Range of Motion
"From pre-intervention to post-intervention within a single session lasting approximately 20 minutes."
Hip External Rotation Range of Motion
"From pre-intervention to post-intervention within a single session lasting approximately 20 minutes."

Interventions
This technique is a high velocity low amplitude thrust (HVLAT) directly posterior to the greater trochanter which theorizes the quick stretch of the external rotator muscles and may improve a malpositioned femoral head within the acetabulum.
