초록

본 연구는 체감형 가상현실 훈련이 뇌졸중 환자의 인지기능과 일상생활활동에 미치는 효과를 알고자 하였다. 급성기 뇌졸중 환자 41명이 본 연구에 참여하였다. 실험 시작 후, 모든 대상자는 실험군 20명과 대조군 21명으로 무작위로 배정되었다. 두 군은 하루 30분, 주 5회, 4주 동안 보편적인 작업치료를 총 20회기 받았다. 실험군은 체감형 가상현실 훈련을 회기 마다 30분 더 받았으며, 대조군은 보편적인 작업치료를 회기마다 30분 더 받았다. 결과측정은 중재 전과 후에 측정하였다. 인지기능을 확인하기 위하여 Loewenstein 인지평가를 측정하였으며, 집중력과 시각기억을 알아보기 위하여 선추적 검사와 시각기억을 측정하였다. 일상생활활동 능력을 알아보기 위하여 수정바델지수를 사용하였다. 연구 결과, 실험군 18명, 대조군 18명은 특정 문제없이 실험을 완료하였다. 인지기능의 변화량에서 실험군은 대조군보다 집중력과 시각적 작업기억에서 유의하게 더 큰 향상이 있었다(p<.05). 일상생활활동의 변화량을 비교에서 실험군은 대조군보다 자조관리에서 유의하게 더 큰 향상이 있었다(p<.05). 본 연구의 결과는 체감형 가상현실 훈련이 보편적인 치료보다 급성기 뇌졸중 환자의 인지기능과 일상생활능력 향상에 긍정적인 효과를 나타낼 수 있음을 시사한다.

The present study was to investigated the effects of motion-based virtual reality training on cognitive function and activities of daily living in patients with stroke. This study was participated in forty one patients with acute stroke. All subjects were randomly assigned into either the experimental group(n=20) or the control group(n=21). The both groups received the conventional occupational therapy during 30 min a day, 5 a week, 4 a weeks. Additionally, experimental group performed motion-based virtual reality training on each session during 30 min/day, and control group conducted conventional occupational therapy on each session during 30 min/day. The outcome measures were the LOTCA(Loewenstein Occupational Therapy Cognitive Assessment), TMT(Trail Making Test), VM(Visual Memory), K-MBI(Korean Modified Barthel Index). In comparison of change score of cognitive function, the experimental group showed a significantly greater improvements in attention and visual working memory than the control group(p<.05). As a result for change score of activities of daily living, the experimental group showed a significant greater improvement in self care than the control group(p<.05). Our findings suggest that motion-based virtual reality training may have a effects of the improvements of cognitive function and activities of daily living than conventional therapy in patients with acute stroke.
