Abstract

This study analyzed the posture balance of time variation for exercising body a period of time. Posture balance measured output values for the posture balance system of body moving in the multi-parameter. Posture moving variation had three methods such as open and closed eye, head moving and upper body moving. There were checked a parameter that measured vision, vestibular, somatosensory, CNS. This system was evaluated a data through the stability. This system has catched a signal for physical condition of body data such as a data acquisition system, data signal processing and feedback system. The output signal was generated Fourier analysis that using frequency of 0.1Hz, 0.1-0.5Hz, 0.5-1Hz and 1Hz over. The posture balance system will be used to support assessment for body moving the posture balance of time variation. It was expected to monitor a physical parameter for health verification system.

본 논문은 인체의 일정한 운동을 하는 동안에 시간의 변화에 따른 자세균형을 분석한다. 자세균형은 자세에 움직임 변화를 주어 다중파라미터로 변화 산출 값으로 나타냈다. 이렇게 산출된 값을 분석하여 균형자세 시스템을 구성하였다. 자세의 움직임 변화는 3가지 방법으로 눈을 감고 뜨는 방법, 머리를 앞뒤로 움직이는 방법과 상체 움직임 방법이다. 측정한 다중파라미터의 항목은 시각(Vision), 전정기관(Vestibular), 체성감각(Somatosensory), 중추신경계(CNS)이고, 측정파라미터의 평가는 안정성(Stability)으로 확인하였다. 균형자세 시스템은 이러한 변화에서 발생한 신호를 데이터 획득 장치에서 얻고, 신호를 신호 전달 장치를 통하여 전달하였으며, 데이터 분석을 통하여 자세에 대한 평가로 활용하였다. 궤환 시스템은 획득한 데이터를 재조정하는데 사용하였다. 발생되는 신호는 푸리에변환 하였고, 사용되는 주파수는 0.1Hz, 0.1-0.5Hz, 0.5-1Hz와 1Hz 이상을 사용하였다. 본연구의 결과로 시간 변화에서 운동부하를 부여함에 따라 인체의 자세변화에 따라 발생된 신호를 멀티파라미터 상에서 장시간 변화에 대한 파라미터 간의 변화를 통하여 개별 신체의 자세균형에 검증할 수 있는 시스템이 이루어져야 하며, 이를 통하여 새로운 검증 시스템에 활용할 수 있을 것으로 예상한다.
