Background:Altered foot loading during weight bearing is suggested to play a role in the development of patellofemoral pain (PFP). This study aimed to determine foot loading characteristics associated with PFP by assessing center of pressure (COP) during single limb loading in individuals with PFP compared to non-injured controls. Methods:Thirty recreationally active subjects with PFP and 30 non-injured controls had barefoot plantar pressure assessed during single limb squats (SLS) from which, COP parameters (COP velocity and COP index [COPI]) were obtained. Groups were compared using independent t-tests. Results:Individuals with PFP demonstrated greater COPI (P = .042), indicating a more lateral foot loading pattern and exhibited increased overall COP velocity (P = .013) and anterior-posterior COP velocity during SLS compared to controls (P = .033). JAPMA Conclusions:Greater lateral foot loading and increased COP velocity during SLS demonstrated by individuals with PFP may indicate reduced dynamic balance within this patient group, that may be implicated in the development of PFP.
