Background:Patellofemoral pain (PFP) is a common affliction and complex clinical entity. Deficit in neuromotor control of the core may be a remote contributing factor to the development of PFPS. Comparative evaluation of core and extensor mechanism muscle activation patterns between healthy group and patients involved by patellofemoral pain syndrome(PFPS) in a stair stepping task is the aim of this study.Methods: In this non-randomized interventional study fifteen males with PFPS and fifteen asymptomatic controls participated. Electromyographic(EMG) activity of Vastusmedialisobliquus(VMO),Vastuslateralis(VL), Gluteus medius (GMED),Gluteus Maximus (GMAX),Internal oblique (IO) and Erector spinae (ES) were recorded and EMG onsets were assessed in both stepping up (SU) and down (SD).The time of foot contact determined by a foot switch.Results:During SU:Onset times of all muscles except, VL and ES in the controls were significantly less than PFPS group (P
