The gait characteristics between patients with knee osteoarthritis (OA) and a control group, and the efficacy of a 6-month progressive resistance training (PRT) program on dynamic alignment during gait in OA patients, a randomized into experimental and a sham-exercise control group is investigated in this book. Knee adduction moment (KAM) was not greater in the OA group compared to the controls. The OA group walked with increased shank adduction angle. Quality of life, level of habitual physical activity, muscle strength and balance were impaired in the OA group. In the second experiment,...
