Correlation of pain sensitization with muscle strength and angular kinematics in women with patellofemoral pain

摘要

Background: Patellofemoral pain has a poor long-term prognosis, which can be explained by a pain sensitization process. The pain sensitization process may be related to the increase of stress in the patellofemoral joint that is already associated with kinematic alterations and weakness in the musculature of the hip and knee.
