The Effects of Repeated Passive Movement of Different Velocities on Knee Joint Position Sense in Patients With Post-Stroke Hemiplegia

Abstract

1)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.

“…이전 연구들은 다양한 변수들을 조합하여 수행지식 피드백과 결과지식 피드백을 제공하는 방식을 적용한 결과를 보여주었으며, 피드백의 긍정적인 학습효과에 대한 영향들을 제시하고 있다 [16,17]. 그럼에도 불구하 고, 각 피드백방법에 대한 검증 사례들은 제시되었지만, 뇌졸중 환자를 대상으로 균형에 대한 수행지식 피드백 과 결과지식 피드백의 효과성을 동시에 입증하고 비교 한 연구는 아직 부족한 상황이다 [18].…”
