Effects of Hip Abductor and External Rotator Strength Training in Patients With Patellofemoral Pain Syndrome

August 14, 2008 updated by: National Taiwan University Hospital
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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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
