Comparing the Effects of Mobilization With Movement (MWM), Self MWM, and Dynamic Stretching on Hip Internal Rotation)

Overview

This study is looking to address the effectiveness of three different intervention on hip range of motion. There will be a therapist performed mobilization group, a self mobilization group, and a dynamic stretching group. Participants will be recruited from the University of South Carolina and randomly assigned between the three groups to have equal distribution and limit any biases. Participants will come in on two different days in order to receive the intervention on the first and have hip range of motion measured on both days. The investigators will be assessing if there is any significant difference between the three groups.

The goal of this study is to compare the efficacy of three clinical interventions intended to treat hip dysfunctions such as hip osteoarthritis. Physical therapists utilize mobilization with movement clinically to increase range of motion that has been limited by hip pathology. This study will compare mobilization with movement administered by a physical therapist, self-administered mobilization with movement, in which patients are instructed in the maneuver and then perform it at home, and dynamic stretching as instructed by a physical therapist. Efficacy will be judged through changes in hip internal rotation range of motion, a motion which is typically limited in patients with hip pathology. The objectives of the study are to quantify the effects of two different modalities of hip mobilization with movement and dynamic stretching in terms of hip internal rotation increases, and to inform current physical therapy practice by filling gaps in the literature surrounding the therapeutic effects of hip mobilization with movement. This study is intended to better equip physical therapists to select the most appropriate evidence-based interventions, thereby increasing the quality of patient care.
