Abstract

We propose a new training system for the improvement of equilibrium sense using unstable platform. This system consists of unstable platform, computer interface and various softwares. The unstable platform was a simple structure of elliptical-type which included tilt sensor and wireless RF module. To evaluate the effort of balance training, we measured the parameters such as the moving time to the target and duration to maintain cursor in the target of screen. Balance training was carried out for two weeks and we classified the subjects into two groups by the training program. As a result, the moving time was reduced and duration time was lengthened through the repeating training of equilibrium sense using training program of sine curve trace(SCT) and Block game. Especially, there was remarkable improvement at direction which was too difficult for the subjects to balance their body. It was showed that this system had an effort on improving equilibrium sense and might be applied to clinical use as an effective balance training system.

본 논문에서는 불안정판(unstable platform)을 이용한 새로운 인체 평형감각 증진용 훈련 시스템을 제안하였다. 본 시스템은 불안정판, 컴퓨터 인터페이스, 다양한 소프트웨어로 구성되어 있다. 불안정판은 기울기 센서와 무선 모듈을 내장한 타원형의 단순한 구조이다. 균형 훈련의 효과를 평가하기 위해 표적으로의 이동시간(moving time to the target)과 표적 내 유지시간(duration time in the target)과 같은 파라미터(parameter)를 측정하였다. 균형 훈련은 2주간 행해졌고, 훈련 프로그램에 따라 피험자를 두 그룹으로 나누었다. 그 결과, sine curve trace (SCT)와 block game의 훈련 프로그램을 이용한 반복적인 훈련을 통해 이동시간은 짧아졌고, 유지시간은 길어졌다 특히, 피험자가 균형을 유지하기 어려웠던 방향에서의 개선이 두드러졌다. 이로써 본 시스템은 훈련 후 피험자의 평형감각을 향상시킬 수 있었고, 효과적인 평형감각 훈련시스템으로써 임상에의 적용 가능성을 확인할 수 있었다.
