Abstract

In this paper, a new rehabilitation training system was developed to improve equilibrium sense by combining virtual reality technology with a fixed exercise bicycle. The subjects consisted of two groups. A group of young people, was compared against a group of elderly. We measured three different running modes of virtual bicycle system with two successive sets. The parameters measured were running time, velocity, the weight movement, the degree of the deviation from the road, and the variables about the center of pressure. The repeated training, our results showed that the running capability of the elderly improve compared. In addition, it was found out that the ability of postural control and the equilibrium sense was improved with the presentation of the visual feedback information of the distribution of weight. From the results of this experiment, we showed that our newly developed system might be useful in the diagnosis of equilibrium sense or in the improvement of the sense of sight and, somatic, and vestibular sense of the elderly in the field of rehabilitation training.

본 연구에서는 가상현실기술과 자전거를 이용하여 평형감각 실조환자의 진단 및 시각, 전정감각, 체성감각 등을 효율적으로 진단하고 자극, 훈련시킬 수 있는 자전거 시뮬레이터 시스템을 개발하였고, 이 시스템이 평형감각 훈련에 대한 효과를 고찰하였다. 실험 방법은 20대의 건강한 젊은 성인과 70대의 노인을 대상으로 자전거 주행 시에 나타나는 주행시간, 주행속도, 중앙선이탈도, 무게이동과 무게중심의 변화를 측정하여 가상 자전거 시스템이 평형감각 훈련에 어떠한 영향을 미치는지에 대한 유용성을 분석 하였다. 실험결과, 20대의 젊은 성인과 70대의 노인이 훈련 후 주행속도와 주행시간 중앙선 이탈도가 감소하였고, 좌우 무게이동과 무게중심 면적이 모두 감소하였으며 시각적 피드백의 효과가 평형감각에 더욱 유용하다는 결론을 얻었고 시각적 피드백의 효과를 이용하여 복합 감성정보를 활용한 헬스기구나 평형감각 재활 훈련에 활용할 수 있음을 알 수 있었다.
