本文介绍了在不完全脊髓损伤(SCI)患者的早期再教育过程中，使用多个传感器进行步行评估和提供认知反馈。本文针对脊髓损伤患者功能性电刺激步态再教育系统的重要组成部分--摆动相位估计进行了研究。建议的传感系统包括四个加速计，一个陀螺仪放置在瘫痪腿的小腿上，两个测角器分别放置在膝盖和脚踝关节。来自传感器的数据被输入到用于秋千质量评估的数学算法中。该算法的输出是一个数值。计算的产量分为三个级别，每个级别用好、足够和差来定义挥杆质量。这些信息以听觉信号的形式提供给患者。患者被教导要最大限度地努力提高行走质量，也就是说，以一种将产生与水平“良好”相对应的听觉输出的方式来移动受影响较大的腿。
This paper presents the use of multiple sensors for walking assessment and provision of cognitive feedback during early re‐education of incomplete spinal cord injured (SCI) humans. The paper is focused on the swing phase estimation as an important part of the Functional Electrical Stimulation (FES) gait re‐education system for incomplete spinal cord injured persons. The proposed sensory system comprises four accelerometers, one gyro placed at the shank of the paretic leg, and two goniometers placed at the knee and ankle joints, respectively. The data from the sensors are input in the mathematical algorithm applied for swing quality estimation. The output from the algorithm is a numerical value. The calculated output is divided into three levels, each defining the swing quality in terms of good, sufficient, and poor. This information is provided to the patient as an auditory signal. The patient is taught to maximize his efforts to improve the quality of walking, that is, to move the more affected leg in a way that will generate the auditory output corresponding to the level “good”.
