Strength of hip muscle groups in sedentary women with patellofemoral pain syndrome

Abstract

To compare the strength of hip muscle groups in sedentary women with bilateral patellofemoral pain syndrome (PFPS) with a matched control group of sedentary women without PFPS. Twenty four women between 19 and 23 years of age (PFPS group, n=12; control group, n=12) participated in this study. Strength for all 6 hip muscle groups was measured bilaterally in all subjects using a stabilized Hand-held dynamometer. The hip musculature of sedentary women with bilateral PFPS was statistically weaker (range 31%-52%; p< 0.001) than that of the control group for all muscle groups. This study demonstrated a statistically significant weakness of hip muscle groups in sedentary women with PFPS.
