The purpose of this study is to investigate that effect of action observa-tion training (AOT) on knee joint function and balance in total knee re-placement (TKR) patients. The subjects consisted of eighteen post-TKR patients. All participants underwent conventional physical therapy. In addition, patients in the AOT group (n=9) were asked to observe video clips showing daily actions and to imitate them afterward. Patients in the control group (n=9) were asked to execute the same actions as pa-tients in the AOT group. Outcome measures Western Ontario and Mc-Master Universities Osteoarthritis Index (WOMAC) included pain, stiff-ness, function and Timed Up and Go (TUG) test. After intervention, pa-tients in the AOT group score better than patients in the control group. After TUG test, patients in the AOT group and control group were no significant difference between two groups. In addition to conventional physical therapy, AOT is effective in the rehabilitation of post-TKR pa-tients. Action observation training is considered conducive to improving knee functions and ameliorating pain and stiffness, of patients who un-derwent TKR.
