Linear correlation between loci of peak activation and accuracy of performance for the knee force-matching task. Linear correlation between loci of peak activation during the knee task in the Y (anterior/posterior) plane and the accuracy of performance of the knee force-matching task. Data are shown for the osteoarthritis (OA) (black marker and solid line) and control (white marker and dashed line) groups. Note the significant positive correlation between variables for both groups
