The purpose of this study is to compare the effects of a mobilization with movement (MWM) technique performed by a physical therapist with those of a dynamic stretch with over pressure on active hip flexion range of motion (ROM) in those with active hip flexion ROM limitations. There is limited evidence available in the literature examining the therapeutic effects of MWM at the hip, the long term effects of MWM, or whether one modality is more effective than another. This study seeks to address these gaps in the literature by directly comparing the results of these two manual therapy interventions on active hip flexion ROM.
This study aims to compare the effects of a therapist-performed mobilization with movement (MWM) technique with those of a dynamic stretch with over pressure on active hip flexion range of motion (ROM) in those with active hip flexion ROM limitations.Those individuals from the University of South Carolina's Department of Physical Therapy (UofSC DPT) community who are interested in becoming study participants will be identified by means of announcements made in the Seminar in Physical Therapy course which is attended by all students, faculty, and staff of UofSC DPT each week. Interested individuals will be provided with Cathy Arnot's email address in order to schedule an evaluation session to determine whether or not they meet the study's inclusion and exclusion criteria. In addition, Sarah Cooper will attend a staff meeting at Vertex PT Specialists to make an announcement and provide the attendees with Cathy Arnot's email for inquiries. Participants will be assigned to either the MWM group or the dynamic stretch with over pressure group via blocked randomization for sex and age, with at least seventeen participants being placed into each group. The MWM group participants will receive a therapist-performed MWM technique and a prescription for a home exercise program (HEP) consisting of a dynamic stretch with over pressure to be performed once a day over the course of the following week. The dynamic stretch with over pressure group participants will receive only the prescription for the HEP consisting of the dynamic stretch with over pressure to be performed once a day over the following week. Measurements will be assessed at four time points: Immediately before the intervention, immediately after the intervention, 24 hours after the intervention, and one week after the intervention.

The participants will receive a therapist performed mobilization with movement and then instructed in a stretching program to be followed for one week or only receive instruction in a stretching program to be followed for one week on the hip with the greatest limitation in motion. The hip with the least amount of limitation will not receive an intervention.

Degrees of change in hip flexion range of motion will be measured using a goniometer at baseline.
Degrees of hip flexion range of motion will be measured before intervention with the participant in supine .All measurements will be taken using a goniometer which measures range of motion in degrees from 0-360.
Time frame: Baseline
Degrees of change in hip flexion range of motion will be measured using a goniometer immediately after intervention.
Degrees of hip flexion range of motion will be measured immediately after intervention with the participant in supine .All measurements will be taken using a goniometer which measures range of motion in degrees from 0-360.
Time frame: Immediately post-intervention.
Degrees of change in hip flexion range of motion will be measured using a goniometer 24 hours after intervention.
Degrees of hip flexion range of motion will be measured 24 hours after intervention with the participant in supine. All measurements will be taken using a goniometer which measures range of motion in degrees from 0-360.
Time frame: 24 hours after intervention.
Degrees of change in hip flexion range of motion will be measured using a goniometer one week after intervention.
Degrees of hip flexion range of motion will be measured one week after intervention with the participant in supine. All measurements will be taken using a goniometer which measures range of motion in degrees from 0-360.
Time frame: 1 week after intervention.
Star Excursion Balance Test (SEBT) at baseline
The participants will perform the posterior, posterolateral, and posteromedial portions of the SEBT. The SEBT is standardized test the participant stands in the center of a mat with "stars" in 8 directions. The particpant stands on one foot and reaches with their opposite foot as far as they can without losing balance. It is method to measure functional hip flexion.
Time frame: Baseline.
Star Excursion Balance Test (SEBT) immediately post-intervention
The participants will perform the posterior, posterolateral, and posteromedial portions of the SEBT. The SEBT is standardized test the participant stands in the center of a mat with "stars" in 8 directions. The particpant stands on one foot and reaches with their opposite foot as far as they can without losing balance. It is method to measure functional hip flexion.
Time frame: Immediately post-intervention.
Star Excursion Balance Test (SEBT) 24 hours after intervention
The participants will perform the posterior, posterolateral, and posteromedial portions of the SEBT. The SEBT is standardized test the participant stands in the center of a mat with "stars" in 8 directions. The particpant stands on one foot and reaches with their opposite foot as far as they can without losing balance. It is method to measure functional hip flexion.
Time frame: 24 hours after intervention.
Star Excursion Balance Test (SEBT) one week after intervention
The participants will perform the posterior, posterolateral, and posteromedial portions of the SEBT. The SEBT is standardized test the participant stands in the center of a mat with "stars" in 8 directions. The particpant stands on one foot and reaches with their opposite foot as far as they can without losing balance. It is method to measure functional hip flexion.
