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

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: A parallel design, also called a parallel group study, compares two or more treatments. Participants are randomly assigned to either group, treatments are administered, and then the results are compared.
Masking: Double


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Mildly Impaired Group<br>This group is with participants with mildly impaired hip internal range of motion, from 25-30 degrees. | Other: Hip Mobilization with Movement, Self-Mobilization with Movement, Dynamic Stretch<br>* Participants receive either a therapist performed mobilization with movement, a self-mobilization with movement, or a dynamic stretch.<br>|
| Active Comparator: Moderately Impaired Group<br>This group is with participants with moderately impaired hip internal range of motion, from 20-24 degrees. | Other: Hip Mobilization with Movement, Self-Mobilization with Movement, Dynamic Stretch<br>* Participants receive either a therapist performed mobilization with movement, a self-mobilization with movement, or a dynamic stretch.<br>|
| Active Comparator: Severely Impaired Group<br>This group is with participants with severely impaired hip internal range of motion, less than 20 degrees. | Other: Hip Mobilization with Movement, Self-Mobilization with Movement, Dynamic Stretch<br>* Participants receive either a therapist performed mobilization with movement, a self-mobilization with movement, or a dynamic stretch.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Degrees of change in hip internal range of motion measured using a bubble inclinometer | Degrees of change in hip internal range of motion will be measured before and after the intervention as well as a 24 hour follow up measurement to determine the duration of the increased range of motion before returning to baseline. All measurements will be taken using a bubble inclinometer which measures range of motion of a joint in degrees from 0-360. | Baseline, immediately post-intervention, 24 hours after intervention |
