Abstract

Objective : The purpose of this study was to investigate the effect of occupational therapy intervention using a fully immersive virtual reality device on the upper extremity function of patients with chronic stroke. Methods : This study used a single subject (ABA) design. The study subjects was a chronic stroke patient with left lateral deviation. Four baseline periods, 12 intervention periods, and 4 baseline regression periods were performed for a total of 20 sessions for 10 weeks. OT intervention with a fully immersive virtual reality device was used every 30 minutes. BBT and WMFT evaluations were performed at each session and the results were displayed in a line graph. Results : The patient's upper limb function has improved. During baseline recurrence, efficacy of treatment was confirmed after removal of intervention, but no significant changes were observed. Conclusion : It has been found that OT intervention with a fully immersive virtual reality device for upper limb function in chronic stroke patients is an effective intervention. However, the effectiveness of maintaining treatment is not important, so we need to develop an easy-to-use home intervention program.

목적 : 본 연구는 만성 뇌졸중 환자를 대상으로 완전 몰입형 가상현실 기기를 이용한 작업치료 중재가 환자의 상지기능 향상에 미치는 효과를 알아보고자 하였다. 연구방법 : 본 연구의 연구 대상은 좌측 편마비를 가지고 있는 만성 뇌졸중 환자 1명이며, 개별사례 실험연구 중 ABA 설계를 사용하였다. 기초선 기간 4회, 중재 기간 12회, 기초선 회귀기간 4회로 총 20회의 실험을 휴지기간을 포함하여 총 10주간 진행하였다. 독립변수인 완전 몰입형 가상현실 기기를 이용한 작업치료 중재는 매 회기 30분씩 시행되었으며 종속변수 중 Fugl-Meyer Assessment(FMA) 평가는 각 기간 마다 1회씩 측정하였다. Box and Block Test(BBT) 평가와 Wolf Motor Function Test(WMFT) 평가는 매 회기 마다 시행하여 그 측정 결과를 꺾은선 그래프를 통해 제시하였다. 결과 : 완전 몰입형 가상현실 기기를 이용한 작업치료 중재 후 대상자의 환측 상지기능이 향상되었다. 기초선 회귀 기간에는 중재를 제거한 뒤 치료유지 효과를 확인하였지만 큰 변화는 나타나지 않았다. 결론 : 본 연구의 결과, 완전 몰입형 가상현실 기기를 이용한 작업치료 중재가 만성 뇌졸중 환자의 상지기능에 효과적인 중재라는 것을 알 수 있었다. 다만 치료유지 효과는 크지 않았기 때문에 보다 사용이 간편한 가정용 중재 프로그램 등의 개발이 필요하다.
