Comparison of hip abductors' strength and 2D frontal plane projection angle during two functional tests, in females with and without patellofemoral pain.

Introduction: Hip abductors eccentrically maintain leg alignment during weight-bearing exercises. Hip abductors' weakness may be a significant aspect to take into account in the conservative management of Patellofemoral Pain (PFP). The aim of the study was to compare hip abductors' eccentric strength and hip kinematics during two functional tests, in female subjects with PFP.
