Comparative evaluation of core and knee extensor mechanism muscle activation patterns in a stair stepping task in healthy controls and patellofemoral pain patients

ABSTRACT

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
