Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
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).
Pre and Post 8 weeks of exercise
Study Arms (3)
Leg Press
ACTIVE COMPARATORLeg Press exercise for 3 times/week and sustain for 8 weeks.
Hip Exercise
EXPERIMENTALAdditional 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.
Control
NO INTERVENTIONEducation was given during 8 weeks of study period. After 8 weeks of study, exercise was given as compensation.
