Official Title: The Effects of Protonics Knee Brace Versus Hamstring Resisted Exercise on Individuals With Patellofemoral Pain Syndrome

Brief Summary: To compare the effect of Protonics knee brace and Hamstring Resisted Exercise (HRE) on anterior pelvic tilt, hip internal rotation and adduction, and knee pain in subjects with Patellofemoral pain symptoms (PFPS) and examine the reliability and validity of self-report patellofemoral disability index (PDI) as a measure of functional performance in subjects with PFPS.

Detailed Summary:

The purpose of this graduate student research study is to compare the effect of Protonics knee brace and Hamstring Resisted Exercise (HRE) on anterior pelvic tilt, hip internal rotation and adduction, and knee pain in subjects with Patellofemoral pain symptoms (PFPS) and examine the reliability and validity of self-report patellofemoral disability index (PDI) as a measure of functional performance in subjects with PFPS.

There will be three visits over 4 weeks for 1 hour per visit, but the first visit will take about 2 hours. In visit one, participants will be asked to sign an informed consent, complete five questionnaires. Then, your hip range of motion (ROM), pelvic tilt angle, and lateral step-up test will be measured. Participants will be randomly assigned to one of two groups: group one receiving the Protonics knee brace exercise, and a home program or group two getting the hamstring-resisted exercise using sport cord and home program. Participant in both groups will walk a specific distance in each phase. Phase I (walk 5 min in straight surface), Phase II (walk 8 min in inclined surface), and Phase III (walk 10 min in different direction).

Current Primary Outcome: Anterior Pelvic Tilt [ Time Frame: Baseline ]

measured while subjects are in a standing position between the anterior superior iliac spine (ASIS) and posterior superior iliac spine (PSIS), to find the oblique angle of the pelvic


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Hip internal, external rotation and adduction active ROM [ Time Frame: Baseline ]
    Subjects will be positioned in supine position to examine the hip ROM
  • Hip internal, external rotation and adduction active ROM [ Time Frame: 15 minutes after intervention ]
    Subjects will be positioned in supine position to examine the hip ROM
  • Hip internal, external rotation and adduction active ROM [ Time Frame: 2 weeks ]
    Subjects will be positioned in supine position to examine the hip ROM
  • Hip internal, external rotation and adduction active ROM [ Time Frame: 4 weeks ]
    Subjects will be positioned in supine position to examine the hip ROM
  • Lateral Step Test [ Time Frame: Baseline ]
    Subjects will be asked to report a verbal pain score during the step-up test at each test session
  • Lateral Step Test [ Time Frame: 15 minutes after intervention ]
    Subjects will be asked to report a verbal pain score during the step-up test at each test session
  • Lateral Step Test [ Time Frame: 2 weeks ]
    Subjects will be asked to report a verbal pain score during the step-up test at each test session
  • Lateral Step Test [ Time Frame: 4 weeks ]
    Subjects will be asked to report a verbal pain score during the step-up test at each test session
  • Anterior Pelvic Tilt [ Time Frame: 15 minutes after intervention ]
