这项工作提出了一种自动同步两种有前途的步态训练技术的方法，以解决中风幸存者的步态缺陷：使用肌内电极的功能性电刺激（FES-IM）和Lokomat机器人步态矫形器。研制了一套实现自动同步的软硬件系统。通过一系列台架试验验证了自动同步的可行性和可靠性。台架试验表明，FES-IM与Lokomat步态周期的自动同步是可行和可靠的。自动同步比手动触发的刺激更一致（延迟的标准差小10倍），并且在634个步幅中没有产生早期或错过的刺激。自动同步比手动触发的刺激具有更高的准确性，产生的刺激定时的准确性为一个步态周期持续时间的2.5%（脚跟撞击到脚跟撞击= 100）。
This work presents a means to automatically synchronize two promising gait training technologies to address gait deficits in stroke survivors: 'functional electrical stimulation using intramuscular electrodes (FES-IM) and the Lokomat robotic gait orthosis. A system of hardware and software was developed to achieve the automatic synchronization. A series of bench tests were performed to verify the feasibility and reliability of automatic synchronization. The bench tests showed that automatic synchronization of FES-IM to the Lokomat gait cycle was feasible and reliable. Automatic synchronization was more consistent than manually triggered stimulation (10-fold smaller standard deviation of latency), and produced no early or missed stimulations across 634 strides. Automatic synchronization had greater accuracy than manually triggered stimulation, producing stimulation timed to an accuracy of 2.5 % of one gait cycle duration (heel strike to heel strike = 100).
