Abstract
The current treatment for ambulation after spinal cord injury (SCI) is to substitute the lost behavior with a wheelchair; however, this can result in many co-morbidities. Thus, novel solutions for the restoration of walking, such as brain-computer interfaces (BCI) and functional electrical stimulation (FES) devices, have been sought. This study reports on the first electroencephalogram (EEG) based BCI-FES system for overground walking, and its performance assessment in an individual with paraplegia due to SCI. The results revealed that the participant was able to purposefully operate the system continuously in real time. If tested in a larger population of SCI individuals, this system may pave the way for the restoration of overground walking after SCI.
摘要
目前脊髓损伤（SCI）后步行的治疗方法是用轮椅替代失去的行走能力；然而，这可能会导致许多并发症。因此，人们一直在寻求恢复行走的新解决方案，如脑机接口（BCI）和功能性电刺激（FES）设备。本研究报告了首个基于脑电图（EEG）的用于地面行走的BCI-FES系统，以及对一名因SCI导致截瘫的个体的性能评估。结果显示，参与者能够实时连续地有目的地操作该系统。如果在更多的SCI个体中进行测试，该系统可能为SCI后地面行走的恢复铺平道路。
