Trunk and Lower Extremity Kinematics During Stair Descent in Women With or Without Patellofemoral Pain.

Context: There is limited evidence indicating the contribution of trunk kinematics to patellofemoral pain (PFP). A better understanding of the interaction between trunk and lower extremity kinematics in this population may provide new avenues for interventions to treat PFP.

Objective: To compare trunk and lower extremity kinematics between participants with PFP and healthy controls during a stair-descent task.
