本研究旨在开发一套气动步态训练系统。本研究以一改良型长肢矫形器及一跑步机系统为基础，研制出一气动式步态训练系统。采用与人体肌肉系统相似的气动驱动器作为髋关节和膝关节屈伸运动的驱动器。该气动步态训练原型系统可用于陆地和水下环境。通过在陆地和水下条件下的实验测试，对该系统进行了评价。实验结果表明：1）在正常步态下，人的髋关节和膝关节的运动模式与水下步态相似; 2）在陆地步态下，下肢肌肉的活动度在整个步态周期内呈下降趋势; 3）在水下步态下，髋伸肌和膝屈肌的活动度在站立期呈下降趋势。本研究结果显示，气动步态训练系统对多种运动障碍的步态训练可能是有效的。
The aim of this study is to develop a pneumatic gait training system. This study report the prototype of pneumatic gait training system based on a modified long-leg orthosis and a treadmill system. The special pneumatic actuator, the similar actuator to human muscular system, was used as the actuator for hip and knee flexion/extension movement. This prototype system of pneumatic gait training is able to utilize for both land and underwater environments. We evaluated this system by the experimental test on land and underwater conditions. It is indicated from the experiment test that 1) the hip and knee joint movement patterns of both on land and underwater gait were quite similar kinematics for normal gait pattern, 2) the activity of lower limb muscles decreased across the gait cycle on land gait, 3) the activity of hip extensor and knee flexor muscles decreased during stance phase in underwater gait. These results of this study suggest that the pneumatic gait training system might be effective for gait training to several motor disorders.
