Abstract

The aim of this study was to determine whether forward or lateral step-down tasks were more sensitive in detecting lower limb misalignment in individuals with patellofemoral pain syndrome (PFPS). The PFPS group (n=26) and the healthy controls group (HC) (n=20) performed the forward step-down (FSD) and the lateral step-down (LSD). Lower extremity kinematic metrics were captured by an 8-camera motion capture system. A two-way ANOVA assessed the effect of group and sex on these metrics. Results revealed that in FSD, there was only a main effect of sex. In LSD, PFPS showed greater peak hip adduction angle (p = 0.04), peak hip internal rotation angle (p = 0.01) and peak pelvic angular velocity. The lateral step-down task emerged as a more sensitive tool for quantitatively evaluating abnormal dynamic lower limb force lines in PFPS.
