Basic reseearch on evaluation of training in stepping and walking

1993年至1995年，用稳定仪、步态记录仪和录像机对人体站立和步行时的姿势进行了为期3年的研究。这些仪器所测得的站立和行走参数值可作为眩晕患者运动训练效果评价的依据。稳定性分析和步态记录仪所显示的足底压力点的分布，可以从人体运动电生理学研究的不同角度提供重要的信息.稳定性记录仪测力板的XY输出被转换成数字数据和稳定性测量参数，如摇摆路径的总长度，平衡动肌的面积，用自制的软件和PC 9801计算了X、Y方向的最大宽度和速度。12例年龄25 ~ 63岁（平均40岁）的健康人的平均值和标准差与文献值进行了比较。两足站立时，闭眼时除XY最大宽度外，其余各参数均显著大于睁眼时，单足站立时闭眼与睁眼时各参数的差异均显著。对步进过程中的数据和向前一步的数据进行了相同的分析。单足站立和踏步时足底压力分布对个体有一定的参考价值，但在大多数情况下，单足站立时足底压力主要由足跟、足趾和手指根部承受。稳定性测量参数的正常值应作为今后体育锻炼目标值。

Human posture in standing and stepping has been investigated by using a stabilometer, a gait corder and a video recorder for 3 years from 1993 to 1995. The values of parmeters concerning standing and walking obtained by those divices should be utilized for the evaluation of physical training in dizzy patietns. Stabilographical analysis and distributions of pressure points at the foot base revealed by a gait corder might give us important informations from the different view of electrophysiological study in human motion.XY output from a force plate of stabilometer was transformed to digital data and parmeters of stabilomtry, such as total length of the sway path, area of a statokinesigram, the maximum width of both X and Y directions and the velocities were calculated by using a self made software and PC9801. The mean and the SD of them obtained in 12 healthy subjects, aged 25 to 63 (mean : 40 years) were compared with the values in several literatures. The values except XY maximum width were significantly larger in the case with eyes closed than with eyes open in bipedal standing and the difference between with eyes closed and with eyes open was significant in the values of all parameters during standing on one foot. Same analyzes of the data during stepping and one step foreward were carried out. The pressure distributions at the footbase in one foot standing and stepping were valuable in each individul but in most of the cases the heal, the toe, and the base of the 5the finger spported the body weight in standing on one foot. The normal values of parameter in stabilomtry should be utilized as the values at the goal after physical training in furture.
