我们之前的研究开发了一种简单的功能性电刺激 (FES) 自行车控制系统，可通过脚踏轮椅进行控制。然而，它需要在骑行前测量每块受刺激肌肉的肌肉反应时间。此外，受试者之间和试验之间的骑行速度也有所不同。在这项研究中，刺激计时模式是根据 EMG 信号确定的，并在健康受试者的脚踏轮椅 FES 循环中进行测试。基于肌电图的刺激时机，将股直肌的刺激开始时机修改为与股外侧肌相同，被证明可以有效提高 FES 循环的速度和稳定性。该计时模式可能很实用，因为它不需要测量肌肉反应时间。
A simple functional electrical stimulation (FES) cycling control with the pedaling wheelchair was developed in our previous study. However, it needed measurement of muscle response time of each stimulated muscle before cycling. In addition, cycling speed varied between subjects and between trials. In this study, stimulation timing pattern was determined based on EMG signals and tested in FES cycling for the pedaling wheelchair with healthy subjects. The EMG-based stimulation timing, in which stimulation start timing for the rectus femoris was modified to be the same as the vastus lateralis, was shown to be effective improving cycling speed and stability of FES cycling. The timing pattern could be practical because it does not require measurements of muscle response times.
