The object of our research was to develop a training support system for recovery of ambulatory function by cerebral hemiplegia patients which would allow frequent walking training with receipt of appropriate feedback on abnormal gait.1. During development of the ambulatory training support system, three-dimensional analysis of lower limbs during walking by healthy individuals was used to investigate lower limb motion in order to distinguish the swing leg phase of the paralyzed limb. The results showed that the vertical displacement of both ankles could serve as a variable indicating the contact phase-swing phase of each leg.2. We developed an ambulatory training support system employing a real-time spatial measurement device. The system was designed to improve paralyzed lower limb function in cerebral hemiplegia patients by providing vibrating stimulatory feedback from a miniature vibrating motor during the paralyzed limb swing phase of walking. The use of vibratory stimulation as feedback is intended to promote motion of the active limb by the patient. The fact that kinetic information on the walking leg of the patient is used directly in a feedback system to improve paralytic gait, and the use of vibrating stimulation as feedback stimulation are distinctive features of this training system.3. The system was installed in a specialized rehabilitation hospital and tested for clinical application. When the training support system for ambulatory recovery developed in our research was applied in walking by hemiplegia patients, the step duration of both legs was nearly equalized during walking in which vibrating stimulatory feedback was applied to the affected leg; the lift height of the paralyzed leg during the swing phase was also increased, demonstrating the efficacy of the system.

我们的研究目的是开发一种训练支持系统，用于脑偏瘫患者的运动功能恢复，该系统允许频繁的步行训练，并收到适当的步态异常反馈。在动态训练支持系统的开发过程中，通过对健康人行走时下肢的三维分析来研究下肢运动，以区分瘫痪肢体的摆动腿阶段。结果表明，双踝关节的垂直位移可以作为指示每条腿接触相位摆动相位的变量。我们开发了一个采用实时空间测量装置的门诊训练支持系统。该系统旨在改善脑偏瘫患者瘫痪的下肢功能，通过在瘫痪的肢体摆动阶段提供微型振动电机的振动刺激反馈。使用振动刺激作为反馈是为了促进患者主动肢体的运动。在反馈系统中直接使用患者行走腿部的动力学信息来改善瘫痪步态，并使用振动刺激作为反馈刺激是该训练系统的显著特点。该系统已在一家专业康复医院安装，并进行了临床应用测试。将本研究开发的运动恢复训练支持系统应用于偏瘫患者行走时，在患腿上施加振动刺激反馈，行走时两腿的步长几乎相等；在摆动阶段，瘫痪腿的提升高度也有所增加，证明了该系统的有效性。
