In this study, variation of sensibility and body action form with aging were investigated and analyzed to study the aged sense of walk on various way. Kinematics and kinetics were applied to analyzed the aged locomotion. Methods of human engineering were applied to analyzed the aged sensibility. The aims of this study was to evaluate levels of ADL (activity of daily living) to develop systems for evaluation. Concrete contents of this study were categorized into five parts such as below ; 1) biomechanical gait analysis of the aged including walk on flat, slope and stairs. 2) biomechanical evaluation of stumble to step at upstairs locomotion. 3) the effect of handrail on dynamically locomotive stability of aged. 4) analysis of visual perception for the aged drivers. 5) an evaluation of the aged color sensation.These measurements were used the anaphase aged subjects (above 75 years old) and were considered sufficiently about safety, simple ness and brief measurements. This study gave the … More load of subjects were controlled minimum. The video camera system and electric conductive rubber sensor system were used to measure the joint motion of lower extremity and the foot pressure during gait, respectively. The driving simulator with the eye-mark recorder was used to evaluate the visual perception ability and sensation for the aged.According to the results of this research, the facts was revealed that human gait form changes with aging such as below ; 1) the contacting area of sole to land surface is kept wider than the young, 2) the impact load at kicking off and contacting to land surface is softened, etc. About the visual perception it was found that aged people have tendencies getting various optical information continually more by moving their eyeballs and central gaze than surrounding gaze which younger people's way of visual recognition and consequently makes them be able to catch much more subjects seen. Thus we see some applications shall be available on the basis of these results mentioned above, for example to estimation of ADL, to decision of rehabilitation programs, etc. Less

本研究通过对老年人感觉和身体动作形式随年龄增长的变化进行调查和分析，研究老年人对不同路径的步行感觉。应用运动学和动力学方法对老年人的运动进行分析。运用人体工程学的方法对老年人的敏感性进行了分析。本研究的目的是评估日常生活能力（ADL）水平，以开发评估系统。本研究的具体内容分为以下五个部分：1）老年人平地行走、斜坡行走和楼梯行走的步态生物力学分析。2)楼梯运动时绊到台阶的生物力学评估。3)扶手对老年人动态运动稳定性的影响。4)老年驾驶员视知觉分析5)老年色觉的评价，这些测量方法用于老年人后期（75岁以上），充分考虑了其安全性、简便性和测量的简洁性。这项研究给出了 ...更多信息 受试者负荷控制在最低限度。分别采用摄像系统和导电橡胶传感器系统测量步态中下肢关节运动和足底压力。利用带有眼标记录仪的驾驶模拟器对老年人的视觉感知能力和感觉进行了评价，结果表明：随着年龄的增长，人的步态形态发生了如下变化; 1）鞋底与地面的接触面积比年轻人要大，2）踢腿和与地面接触时的冲击载荷被软化，关于视觉感知，发现老年人倾向于通过移动他们的眼球和中心注视而不是周围注视来持续地获得各种光学信息，这是年轻人视觉识别的方式，从而使他们能够捕捉到更多的被观察对象。因此，我们看到一些应用程序应可在上述这些结果的基础上，例如，以估计日常生活能力，康复计划的决策，等等。减
