Abstract

Many individuals with stroke express gait abnormalities and reduction of daily living activities. One of techniques for treating lower limb disabilities for improving gait patterns is functional electrical stimulation (FES). The purpose of this case report is to describe the development of FES system based on multi-pad electrodes for foot drop correction during gait and to demonstrate its use in improving gait quality of hémiplégie patients. Stimulation optimization and triggering is based on feedback from inertial sensor positioned on the patient's paretic foot. The main features are fast and reliable optimization of stimulation patterns for achieving strong dorsiflexion and plantar flexion. One hémiplégie patient participated in the 6 months case study. The functional improvement of the patient's gait was tracked during the course of the therapy. Observed indicators of rehabilitation efficiency were gait velocity, number of steps and angular velocity of ankle joint during 10 m gait test.

治疗足下垂的多垫刺激装置:案例研究

许多中风患者表现为步态异常和日常生活活动减少。功能性电刺激(FES)是治疗下肢残疾以改善步态模式的技术之一。本病例报告的目的是描述基于多垫电极的FES系统的发展，用于步态时的足下垂矫正，并展示其在改善hims患者步态质量方面的应用。刺激优化和触发是基于来自惯性传感器的反馈定位在病人的麻痹足。主要特点是快速和可靠的优化刺激模式，以实现强背屈和足底屈。一名hims患者参加了为期6个月的病例研究。在治疗过程中，追踪患者步态的功能改善情况。在10 m步态试验中，观察步态速度、步数和踝关节角速度对康复效果的影响。
