Abstract

The subjects of this study were 30 hemiplegia patients whose disease duration was over 6 months, and they were divided at random into a control group (n=15) receiving traditional rehabilitation therapy and an experimental group (n=15) receiving both traditional rehabilitation therapy and training using IT based EMG biofeedback. The program was applied for a total of 4 weeks. In order to examine the subjects' functional recovery, we measured their upper limb function using FMA and MFT, and activities of daily living using FIM before and after the training. Comparison between experimental groups in the study of upper extremity function improved after training in all tests was higher compared to the control group significantly (p<.05), but activities of daily living were not significantly different in. The results of this study were as follows. we concluded that stroke patients receving intensive IT based EMG biofeedback showed upper extremity functional recovery.

본 연구는 IT 기반 근전도 바이오피드백 훈련이 만성 뇌졸중 환자의 상지기능에 미치는 효과를 알아보고자 실시하였다. 연구는 발병 6개월 이상인 뇌졸중 환자 30명을 무작위로 실험군과 대조군으로 각각 15명씩 배정하였다. 전통적 재활 치료를 받은 대조군과 전통적 재활 치료와 더불어 근전도 바이오피드백 훈련을 추가로 실시한 실험군으로 나누어 총 4주간 연구를 실시하였으며, 상지기능을 검사하기 위하여 훈련 전 후 FMA와 MFT를 실험군과 대조군 모두에게 실시하였고, 일상생활 동작에 미치는 영향을 알아보기 위해 FIM을 사용하여 일상생활 동작을 측정하였다. 연구결과 집단 간 비교에서 실험군의 훈련 후 상지기능 향상이 모든 검사에서 대조군에 비하여 통계적으로 유의하게 높았지만(p<.05), 일상생활 동작에서는 유의한 차이가 없었다. 이러한 결과로 IT 기반 근전도 바이오피드백 훈련이 만성 뇌졸중 환자의 상지 기능을 향상시킨다는 것을 알 수 있었다.
