본 연구는 몰입형 가상현실콘텐츠를 이용한 인지재활이 경도인지장애 노인의 인지 및 시지각 기능과 지루함에 미치는 영향을 알아보고자 실시하였다. 대구∙경북에 소재한 4곳의 재활병원 및 치매안심센터에 내원하는 대상자 64명을 무작위로 실험군과 대조군 각 32명으로 선별한 후, 실험군에게는 몰입형가상현실을 대조군에게는 전통적인 인지재활을 적용하였다. 중재는 4주간 일주일에 5회 하루 30분간 총 20회가 실시되었다. 중재 전과 후의 인지기능을 비교하기 위해 노인용 작업치료인지기능평가도구(LOTCA-G)를 사용하였고, 시지각 기능을 비교하기 위해 Motor-Free Visual perception Test 3(MVPT 3)를 지루함 정도는 다면적 지루함 상태척도(MSBS)를 사용하였다. 본 연구의 결과 인지기능과 지루함 정도는 실험군에서 통계적으로 의미 있는 향상이 있었고, 시지각은 실험군과 대조군 모두 통계적으로 의미 있는 향상이 있었다. 본 연구의 결과를 통해 경도인지장애 노인에게 몰입형 가상현실콘텐츠를 이용한 인지재활을 적용하였을 때 경도인지장애 노인의 인지기능과 시지각, 지루함 정도에 긍정적인 영향을 미친다는 것을 알 수 있었다. 몰입형 가상현실콘텐츠를 이용한 인지재활은 작업치료에서 경도인지장애 노인의 인지 및 시지각 기능과 지루함 정도의 향상을 위한 유용한 중재 방법으로 적용될 수 있을 것이다.
Abstract
This study was conducted to find out the effect of cognitive rehabilitation using immersive virtual reality contents on cognitive and visual perception functions and boredom of the elderly with mild cognitive impairment. 64 subjects who visited four rehabilitation hospitals and dementia safety centers in Daegu and North Gyeongsang Province were randomly selected as 32 persons each in the subject group and the control group. Traditional cognitive rehabilitation for the control group, the immersive virtual reality applications for group. Treatment is total of 20 times a day for 30 minutes five times a week for four weeks was taken. To compare cognitive function before and after treatment, the LOTCA-G was used, and Motor-Free Visual Perception Test 3 (MVPT 3) was used to compare visual perception functions and MSBS was used to compare boredom level. As a result of this study, cognitive function and boredom level had statistically significant improvements in the subject group, and visual perception had statistically significant improvements in both the experimental group and the control group. The results of this study showed that the cognitive rehabilitation using immersive virtual reality contents to the elderly with mild cognitive impairment had a positive effect on the cognitive function, visual perception, and boredom.
