The purpose of this study was to understand the influence of patellofemoral pain on lower extremity segment coordination variability throughout a 21-minute treadmill run. Couplings between the pelvis, thigh, and shank were compared at the beginning and end of the run between healthy and injured runners. Average coordination variability in weight acceptance and mid-stance was increased in healthy runners over the course of the run and decreased in those experiencing pain. These results support the hypothesis that injured runners experiencing pain may not be as flexible to internal and external perturbations compared to their healthy counterparts. Thus, in the presence of pain, these runners may place greater stress on specific lower extremity tissues leading to greater risk for injury at these sites.
