Evaluation and therapeutic efficacy of a training support system for ambulatory recovery in cerebral hemiplegia patients

本研究的目的是开发一种训练支持系统，用于脑性偏瘫患者步行功能的恢复，该系统允许频繁的步行训练，并对异常步态进行适当的反馈.在步行训练支持系统的开发过程中，健康人在步行过程中的下肢的三维分析被用来研究下肢运动，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反映各腿接触阶段-摆动阶段的变量.我们开发了一个流动训练支持系统，采用实时空间测量设备。该系统旨在通过在步行的瘫痪肢体摆动阶段提供来自微型振动电机的振动刺激反馈来改善脑偏瘫患者的瘫痪下肢功能。使用振动刺激作为反馈旨在促进患者活动肢体的运动。事实上，患者步行腿的动力学信息直接用于反馈系统以改善瘫痪步态，以及使用振动刺激作为反馈刺激是该训练系统的显著特征。该系统已安装在一家专门的康复医院，并进行了临床应用测试。将本研究所开发的步行康复训练支持系统应用于偏瘫患者的步行中，在步行过程中，对患腿施加振动刺激反馈，使双腿的步行持续时间几乎相等;在摆动阶段，瘫痪腿的抬起高度也有所增加，证明了该系统的有效性。

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.
