Effects of Hip Abductor and External Rotator Strength Training in Patients With Patellofemoral Pain Syndrome - Full Text View

Sponsored by:	National Taiwan University Hospital
Information provided by:	National Taiwan University Hospital
ClinicalTrials.gov Identifier:	NCT00736736

Purpose

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.

Primary Outcome Measures:

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 ]

Enrollment:	85
Study Start Date:	March 2008
Primary Completion Date:	July 2008 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
Leg Press: Active Comparator Leg Press exercise for 3 times/week and sustain for 8 weeks.	Other: Leg Press Exercise
Hip Exercise: Experimental 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
Control: No Intervention Education was given during 8 weeks of study period. After 8 weeks of study, exercise was given as compensation.
