Simulation Exercise of Hemiplegic Gait by Utilizing Illusory Kinesthesia of Leg and Educational Use

在理疗生和护生的一堂实习课上，通过模拟偏瘫患者的体验，提高对偏瘫患者情况的了解。一种常用的模拟方法是对健康受试者的四肢进行负重和约束，并指出了该方法的不足。因此，研究者将注意力集中在偏瘫患者行走过程中自省的意义上，我们设计了一种新的方法来模拟偏瘫患者，通过影响肢体动作和感知之间的交互作用来实现。基于这一思想，我们设计并开发了一种振动腿关节肌腱的实验装置，以产生虚幻的运动和反射动作。最后，我们研究了我们的设备是如何影响健全人的步态的，我们还举办了关于体验我们的设备来模拟偏瘫行走的研讨会。

In a class of practical work for physiotherapy students and nursing students, those students experience simulation of hemiplegia patient to improve understanding on situation of such patient. A well-known method on the simulation is to load weight and restraint on extremities of an able-bodied subject, and weaknesses of the method are pointed out. Therefore applicants have focused on significance of introspection of hemiplegia patient during walking, and we have devised a novel method on a simulation of hemiplegia patient by influencing on an interaction between action and perception of lower extremity. Based on this idea, we have designed and developed an experimental device that vibrates tendons of leg joints for generating illusory kinesthesia and reflex action. Finally we investigated how our device influenced a gait of able-bodied person, and we gave workshops on experiencing our device forsimulation of hemiplegic walk.
