项目摘要

This study has been performed for 3 years, 1992-1994, for the purpose to establish a method to measure human body sways during standing, stepping and other physical exercises and to analyze their data by using a stabilometer and micro-computer.1. A series of position data of both X and Y components of the center of the foot pressure(CFP) in each subject, standing, stepping and doing truncal or head movements, were measured by using a stabilometer(1G06). Those data were transformed to a PC-9801 microcomputer as digital data and were analyzed. A direct method to calibrate the data from a stabilometer was also devised.2. Aging effects, appeared in human standing on both feet with eyes open and closed, were investigated in normal 285 subjects who had visited Kitasato Univ. Hospital(198 males and 87 females). By comparing the mean value and standard deviation of the length of total sway path in the group of each decade with the values in the group of 2 decades, increase of body sway was demonstrated in male subjects of 6 and 7 decades (P<0.05) and in females of 7 decades (P<0.01) during standing with eyes open but not with eyes closed.3. Movements of the CFP during stepping and several exercises on erect posture were investigated by using a stabilometer. At the swing phase of stepping, CFP moved quickly forward and then backward in association with rapid lateral shift to the other side and at the stance phase the most lateral shift of CFP, which followed by a little forward medial, and then, backward lateral deviations were demonstrated. Body sways during inclination of the trunk in fore and backward, and lateral directions and twist of the trunk gave dominant movements of CFP in the horizontal, vertical and horizontal-vertical directions, respectively.

本研究从1992-1994年进行了3年，目的是建立一种利用稳定器和微型计算机测量人体在站立、步进和其他运动过程中的摆动的方法，并对其数据进行分析。使用稳定器(1G06)测量了每个受试者站立、行走和躯干或头部运动时足底压力中心(CFP)的X和Y分量的一系列位置数据。将这些数据以数字数据的形式输入PC-9801微型计算机进行分析。还设计了一种直接校准稳定器数据的方法。对285名参观过北里大学的正常受试者进行了双脚站立、睁眼和闭眼的衰老效应研究。医院(男198人，女87人)。通过比较每十年组和二十年组的总摇摆路径长度的平均值和标准差，发现站立时，男性6岁和70岁组(P&lt；0.05)和女性70岁组(P&lt；0.01)在站立时睁眼但不闭眼时身体摇摆增加。使用稳定器研究了CFP在踏步和几种直立姿势下的运动。在步态摆动阶段，CFP快速向前后退，并向另一侧快速侧移；在站立阶段，CFP的最大侧移，然后是轻微的内侧前移，然后是向后的侧向偏移。躯干前后倾斜时的身体摆动，躯干的横向和扭转分别主导CFP在水平、垂直和水平-垂直方向上的运动。
