A Study of Evaluation of Walking Ability and Prevent the Aged Person from the Fell Accident From the Viewpoint of the Postural and Electromyographical Analysis

(1)当一个人在地面上行走时感觉到自己在打滑，最初的时候，腿部关节的伸展会减少。然后，第二，在站立阶段腿部肌肉的活动增加。然后是代表最后阶段的坚持的感觉。(2)通过对30名健康成人水平行走时腿部肌肉活动的定量分析，将踝关节、膝关节和髋关节的放电模式分为两类。(3)定量计算76例60 ~ 85岁老年人水平行走和从椅子上坐起来时腿部肌肉活动水平。由此得出的数据表明，独立水平的腿部肌肉使用了自己的双脚进行步态。(4)在四种不同的行走表面（地板、10厘米深、沙土、成人拳头大小的石头和人造草皮）上，使用七种不同的足部条件（光脚、穿自己的运动鞋、穿骡子、穿磨损、穿日本凉鞋、穿木屐和高跟鞋），分析正常行走时腿部的肌肉活动。踝关节肌肉的功能在预防跌倒事故中起着非常重要的作用。

(1) When a person senses they are slipping while walking on a surface, there is initially a decrease in leg joint extension. Then, second, there is an increase in the activity of the leg muscles during the stance phase. And then there is the sensation of insistence representing the last phase.(2) From the quantitative analysis of the leg muscles' activity of 30 healthy adult subjects during the level walking, the discharge patterns of the ankle, knee and hip joints were classified into two types each.(3) The muscular activity levels in the legs of 76 elderly subjects, aged 60 to 85 years old, during level walking and while standing up from sitting in a chair were calculated quantitatively. The resulting data show that the independent level of the leg muscles for the gait used their own feet.(4) The muscular activities of the legs were analyzed during normal walking on four different walking surfaces (floorboard, 10cm-deep, sandy soil, stones the size of an adult's fist, and artificial turf) using the seven different foot conditions (bare foot, with their own sports shoes, with mules, with scuffs, with Japanese sandals, with wooden clogs and high heels). The function of the ankle joint muscles were shown to be very important for the prevention of falling accident.
