The aim of this study was to examine the effects of repeated passive movement (RPM) of different velocities on the improvement of knee joint position sense (JPS) in post-stroke patients with hemiplegia, thereby investigate the possibility of clinical application in the initial stage of rehabilitation for patients with post-stroke hemiplegia. Thirteen hemiplegic patients participated in this study. For the subjects’ knee JPS tests, a passive angle reproduction test and an active angle reproduction test were performed prior to and after the intervention, which involved 30 repetitions of passive full-range-of-motion flexion and extension exercise of the knee joints at randomized degrees of 0°/s, 45°/s, and 90°/s. Paired t-test analysis was done in order to compare changes in the pre- and post-intervention knee JPS. One-way repeated analysis of variance was used in order to compare changes in JPS after intervention at three different movement velocities. The level of significance was set at .05. The result was that the subjects’ post-intervention knee JPS significantly improved after the RPM exercise at a 45°/s and a 90°/s relative to the RPM exercise 0°/s (p<.05). JPS changes with RPM intervention at the rapid velocity of 90°/s were most increased, suggesting the most effective enhancement in knee JPS is with intervention at the velocity (p<.05). Therefore, RPM intervention at a half or higher velocity improved stroke patients’ knee JPS. During the initial stage of rehabilitation for patients with post-stroke hemiplegia, the efficient application of the RPM exercise at a half or higher velocity will be possible.
