초록

본 연구의 목적은 산학연 공동기술개발사업으로 개발한 가상현실재활시스템이 뇌졸중 환자에게 긍정적인 영향을 주는지 임상 실험으로 알아보고 이를 통해 개발제품의 임상적 사용 가능성을 검증하기 위함이다. 임상실험을 통해 검증하고자 가상현실재활시스템을 재활병원에 입원하고 있는 뇌졸중 24명(뇌출혈 13명, 뇌경색 11명)에게 제공하였다. 실험군(13명)에는 가상현실재활시스템 위주의 훈련을 실시하였고, 대조군(11명)에는 재활치료의 유형인 보편적 기능훈련으로 일상생활활동 훈련, 지필물과 테이블 탑 위주의 인지재활 훈련, 운동조절 훈련을 실시하였다. 실험군과 대조군 모두 주 3회 하루 2회씩 총 8주간 실시하였다. 두 집단 모두 사전사후 기능적 독립 측정(Functional Independent Measure; FIM), 한국형 간이정신상태 검사(Mini-Mental State Examination for Korean; MMSE-K), 자아존중감척도 평가를 실시하였다. 실험결과 가상현실재활시스템을 제공한 집단과 보편적 재활치료를 받은 집단이 일상생활활동, 기초인지, 자아존중감척도에서 유사한 결과를 보였다. 중재 전후를 비교해 본 결과 가상현실재활시스템을 제공한 집단이 중재 전보다 중재 후에 일상생활활동, 기초인지, 자아존중감에서 모두 의미 있는 향상이 있었다(P<.05). 산학공동으로 개발한 가상현실재활시스템이 뇌졸중 환자의 일상생활 기능과 기초 인지능력을 회복시키고, 삶의 만족과 인간행동의 원인이 되는 자아존중감에 긍정적인 영향을 보여 주었기 때문에 가상현실재활시스템의 임상 적용 가능성을 긍정적으로 확인하였다. 추후 연구에서는 가상현실재활시스템을 뇌손상 환자와 치매 환자의 다양한 기능 회복에 대한 임상적 유용성을 검증할 필요가 있다.

The purpose of this study was to verify the clinical usefulness of the virtual reality rehabilitation system which Academic-Industrial cooperation develop through clinical experiment for recovering the functional abilities in stroke. For this purpose, 24 Stroke(hemorrhage13, infarction11)participated in a clinical experiment. They were randomly assigned to the virtual reality rehabilitation system group(n=13) and conventional rehabilitation training(Activities of daily living, cognition training, motor control) group(n=11). All participant were evaluated with three standardized assessment tools(Functional Independent Measure; FIM, Mini-Mental State Examination for Korean; MMSE-K, Self-esteem scale) before and after the planned intervention sessions. All participant were intensively carried out for 8weeks, 3times a week. The results were as follows. The experimental group showed significant improvements for Activities of daily living, basic cognitive abilities and self-esteem related with life satisfaction after the interventions(p<.05). There were no significant differences between two groups for all assessment tool after interventions. Because of this experimental results, the virtual reality rehabilitation system showed the clinical utility for recovering the function in stroke. Further studies are needed to verify the clinical usefulness on the improvement of various functions in brain injury and dementia.
