초록

본 연구는 좌측 편측무시 환자에게 안대로 우측 눈을 가린 후 시각적 피드백 훈련을 하였을 때 균형, 시지각 기능과 편측무시에 미치는 영향을 알아보고자 하였다. 출혈 및 뇌경색으로 뇌졸중이란 진단을 받은 환자로 발병이 6개월 이상 경과하고 연구목적에 동의한 좌측 편마비 환자 25명을 대상으로 하였다. 실험 기간은 2008년 4월 28일부터 2008년 6월 5일까지 6주간 주 5회 30분씩 시행하였다. 실험군(n=13)은 우측에 안대 착용 후 시각적 피드백 훈련을 하였으며, 대조군(n=12)은 우측에 안대 착용 후 체중부하 훈련을 시행하였다. 실험 전후 평가는 균형 검사, 시지각 검사와 선 이등분 검사를 통하여 이루어졌다. 균형 검사의 집단간 비교는 차이를 보이지 않았다. 그러나 전후 비교에서 실험군과 대조군 모두 유의한 향상이 있었다. 시지각 검사인 MVPT-V의 집단간 비교에서 유의한 차이를 보였고, 전후 비교에서 실험군과 대조군 모두 유의한 향상이 있었다. 편측무시 검사인 선 이등분 검사의 비교에서 집단 간에 유의한 차이를 보였고, 전후 비교에서 두 집단 모두 편측무시의 향상이 있었다. 본 연구 결과로 편측무시 환자에게 눈을 가린 후 시각적 피드백 훈련은 균형, 시지각 기능의 회복과 편측무시 감소에 효과적임을 알 수 있었다.

Abstract

This study aims to investigate whether a visual feedback training after the eye patching method on the non-neglected side would lead to less unilateral neglect and visual perception. This study used the pretest-posttest control group design. The subjects were 25 left hemiplegic patients who showed the feature of unilateral neglect. The subjects were randomly assigned into experimental group(n=13) and control group(n=12). The experimental group was asked to participate in visual feedback training & eye patching. The control group was asked to participate in weight bearing training & eye patching. both experimental and control groups participated in exercise classes 30 minutes per day five times a week for 6 weeks. It’s effect was evaluated by the standing balance, MVPT-V, line bisection test. Collected data were statistically analyzed by SPSS Ver. 12.0 using descriptive statistics, paired t-test, ANCOVA. The following results were obtained. In the standing balance, there was not statistical significance between the experimental group and control group. but there was a statistical significance to pre and post test with the experimental group and control group. In the MVPT-V, line bisection test, there was statistical significance between the experimental group and control group. and there was a statistical significance to pre and post test with the experimental group and the control group. As a result, the experimental group was shown effective in reducing unilateral neglect syndrome. Future study considered need to be more the study relative to variable visual feedback training to stroke patients with unilateral neglect.
