초록

본 연구는 증강현실(augmented reality) 기반 트레드밀 보행 훈련이 뇌졸중 환자의 균형과 보행에 미치는 영향을 알아보고 일반적인 트레드밀 보행 훈련과 그 효과의 비교를 목적으로 실시하였다. 연구의 대상자는 재활 훈련에 참여한 65명의 뇌졸중 환자 중 연구 조건에 충족하는 57명을 연구 대상자로 선정하였다. 대상자를 두 그룹으로 나누어 증강현실 기반 트레드밀 보행군 29명과 일반적인 트레드밀 보행군 28명으로 진행하였다. 증강현실 기반 트레드밀 보행군은 준비된 두부 장착형 디스플레이를 착용하고 10분간 트레드밀 보행을 실시하였으며, 일반적인 트레드밀 보행군은 10분간 트레드밀 보행을 실시하였다. 모든 대상자에게 일어나 걸어가기 검사와 보행 능력 검사를 실험 전후에 실시하였다. 연구 결과 증강현실 기반 트레드밀 보행 훈련과 일반적인 트레드밀 보행 훈련은 모두 뇌졸중 환자의 동적 균형 능력을 개선시키는데 효과가 있었다. 또한 증강현실 기반 트레드밀 보행 훈련은 뇌졸중 환자의 시간적 보행 지수인 보행속도와 분속수의 증진과 공간적 보행지수인 보장과 활보장의 증진에 있어서 일반적인 트레드밀 보행 훈련보다 효과적이며, 기능적 보행 지수 능력을 증진 시키는데 효과가 있었다. 위의 결과를 통하여 증강현실 기반 트레드밀 보행 훈련이 뇌졸중 환자의 균형과 보행의 증진에 있어서 효과가 있음을 확인하였다. 향후 뇌졸중 환자의 재활 목적에 맞는 다양한 증강현실 기반 훈련 프로그램의 개발이 필요할 것이다.

Abstract

This study was held in an attempt to examine how the augmented reality-based treadmill training affects balance and gait of stroke patients and to compare the differences of its effects with that of the general treadmill training. The 57 patients were divided into two groups: the 29 patients was the augmented reality-based treadmill training group with the head mounted display on their head for 10 minutes; and the 28 patients was the general treadmill training group who executed only treadmill training for 10 minutes. It is found that, in both cases, there is an effect that improves the dynamic balance ability of stroke patients(p<.05). Moreover, it is also found that the augmented reality-based treadmill training is effective in increasing the ability for velocity and cadence, which is the temporal gait measure, and step-length and stride-length, which is the spatial gait measure, and is more effective than the general treadmill training(p<.05). These results suggest that the augmented reality is feasible and suitable for individuals with stroke. Based on the results on the above, It has been verified that the augmented reality based treadmill training has a positive effect on balance and gait function of stroke patients. Thus it leads us to an assumption that the numbers of programs, which use the augmented reality for various rehabilitation purposes, should be further developed in the future.
