Effects of Hip Abductor and External Rotator Strength Training in Patients With Patellofemoral Pain Syndrome
The first purpose was to compare the difference between leg press exercise(LPE) and additional hip abductor and external rotator muscle strength training to leg press exercise(LPE+HAE) in muscle strength, hip kinematics during step down, pain severity and function for patients diagnosed with patellofemoral pain syndrome. The second one was to discover the relationship between the change in muscle strength performance and the difference of hip joint kinematics post treatment.
Patellofemoral Pain Syndrome
Other: Additional Hip Muscle Strengthening to Leg Press Exercise
Other: Leg Press Exercise
|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Primary Purpose: Treatment
- Muscle Strength by hand-held dynamometry, hip joint kinematics during step down by electromagnetic motion tracking system (FASTRAK, Polhemus ), pain severity by PFPS pain severity scale (PSS), functional performance by Anterior Knee Pain Scale(AKP). [ Time Frame: Pre and Post 8 weeks of exercise ] [ Designated as safety issue: No ]
|Study Start Date:||March 2008|
|Primary Completion Date:||July 2008 (Final data collection date for primary outcome measure)|
Active Comparator: Leg Press
Leg Press exercise for 3 times/week and sustain for 8 weeks.
|Other: Leg Press Exercise|
Experimental: Hip Exercise
Additional hip abductor and hip external rotator strength training to leg press exercise for people in this group. All participants received exercise for 3 times per week for 8 weeks.
|Other: Additional Hip Muscle Strengthening to Leg Press Exercise|
No Intervention: Control
Education was given during 8 weeks of study period. After 8 weeks of study, exercise was given as compensation.
