Relationship Between Functional Tests and Knee Muscular Isokinetic Parameters in Patients with Patellofemoral Pain Syndrome

Sh. Goharpey, M.J. Shaterzadeh , A. Emrani and V. Khalesi

Abstract:
To measure quadriceps and hamstring muscle strength with Isokinetic dynamometer in patients with patellofemoral pain syndrome (PFPS) and also to examine the relationship between muscle strength and functional test scores and subjective assessment. In this case-control study a total of 30 subjects (15 healthy and 15 patients with diagnosed PFPS) completed Kujala questionnaire concerning subjective functional knee assessment. Then muscle strength was measured with Isokinetic dynamometer in sitting position during 10 to 90 degree of knee flexion in 60 and 120 degree per sec speeds. Finally two kinds of functional tests (step down and semi-squat) were performed by each subject. There was no relationship between functional test scores and Isokinetic strength assessment. There was a poor relationship between functional test scores and Kujala questionnaire score (r = 0.47 for semi squat test and 0.37 for step down test). The overall mean scores of quadriceps Isokinetic parameter in 60 degree per sec speed, functional test scores and Kujala subjective knee assessment scores was less in patients with PFPS. This study showed that both Isokinetic dynamometry and functional tests must be done individually in patients with PFPS.
