在本文中，我们介绍了旨在对不完全脊髓损伤者进行 FES 步态再教育的感觉系统。所提出的系统由四个加速度计、陀螺仪和两个测角仪组成，沿着瘫痪腿的小腿放置。评估的数据被输入到估计摆动期质量的数学算法中。该估计基于摆动相位检测和信号相关性，并用于确定认知反馈信号。反馈信号作为听觉信号传递给患者。
初步测量是在三名健康人和两名患有 C6 和 C6-7 损伤的不完全脊髓损伤者在跑步机行走过程中进行的。 FES 由物理治疗师手动触发。结果表明，所提出的多感官系统在步态质量估计方面是成功的。因此，使用 FES 多感觉系统和认知反馈可能是步态恢复的有效康复方法。
In the paper we present the sensory system aimed for FES gait reeducation of incomplete spinal cord injured persons. The proposed system consists of four accelerometers, gyro and two goniometers placed along the shank of the paralyzed leg. The data assessed are input into mathematical algorithms estimating the swing phase quality. The estimation is based on swing phase detection and signal correlation and is used to determine the cognitive feedback signal. The feedback signal is delivered to the patient as an auditory signal.
The preliminary measurements were performed in three healthy and two incomplete spinal cord injured persons with C6 and C6-7 lesion during treadmill walking. FES was manually triggered by a physiotherapist. The results have shown that the proposed multisensory system was successful in gait quality estimation. Therefore, the use of FES multisensory system and cognitive feedback could be an efficient rehabilitative approach in gait reeduction.
