title: Strength of hip muscle groups in sedentary women with patellofemoral pain syndrome.
abstract: OBJECTIVE
  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.
  
  
  METHODS
  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.
  
  
  RESULTS
  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.
  
  
  CONCLUSIONS
  This study demonstrated a statistically significant weakness of hip muscle groups in sedentary women with PFPS.
