Hip rate of torque development, but not strength, is associated with single-leg squat kinematics in individuals with patellofemoral pain.

Introduction: Isometric hip strength seems to have limited association with frontal plane kinematics in individuals with patellofemoral pain (PFP), but little is known about the association with hip rate of torque development (RTD).

Objective: To explore the association of hip strength and RTD with trunk, pelvis, hip, and knee kinematics during a single-leg squat (SLS) in individuals with PFP.

Methods: Twenty individuals with PFP participated in this study.
