步态功能障碍在中风后的个体中非常普遍，并影响多个下肢关节。最近的证据表明，在跑步机上以比自己选择的速度更快的速度行走有助于改善中风后的步态障碍。此外，功能性电刺激（FES）和跑步机训练的结合已成为一种有希望的卒中后步态康复干预方法。然而，结合FES与跑步机行走的不同效果，在快与慢，自我选择的速度，以前没有比较过。在这项研究中，我们比较了中风后个体在跑步机上以自己选择的速度（无FES）、以自己能达到的最快速度（FAST）、以最快速度（FES）和以最快速度（FAST-FES）行走对步态的直接影响。在SS-FES和FAST-FES中，FES在站立末期被输送到松弛的踝关节跖屈肌，在摆动阶段被输送到松弛的背屈肌。我们的研究结果显示，与SS相比，FAST- fes在行走时的峰值前地反力（AGRF）和下肢角度方面有所改善。FAST- fes与SS- fes相比，可导致更大的峰值前地反力（AGRF）、下肢角度和摆动阶段膝关节屈曲。与FAST相比，FAST- fes导致AGRF峰值进一步增加。我们认为，在FAST-FES期间卒中后步态的多个方面的增强表明FAST-FES可能具有卒中后步态康复干预的潜力。
Gait dysfunctions are highly prevalent in individuals post-stroke and affect multiple lower extremity joints. Recent evidence suggests that treadmill walking at faster than self-selected speeds can help improve post-stroke gait impairments. Also, the combination of functional electrical stimulation (FES) and treadmill training has emerged as a promising post-stroke gait rehabilitation intervention. However, the differential effects of combining FES with treadmill walking at the fast versus a slower, self-selected speed have not been compared previously. In this study, we compared the immediate effects on gait while post-stroke individuals walked on a treadmill at their self-selected speed without FES (SS), at the SS speed with FES (SS-FES), at the fastest speed they are capable of attaining (FAST), and at the FAST speed with FES (FAST-FES). During SS-FES and FAST-FES, FES was delivered to paretic ankle plantarflexors during terminal stance and to paretic dorsiflexors during swing phase. Our results showed improvements in peak anterior ground reaction force (AGRF) and trailing limb angle during walking at FAST versus SS. FAST-FES versus SS-FES resulted in greater peak AGRF, trailing limb angle, and swing phase knee flexion. FAST-FES resulted in further increases in peak AGRF compared to FAST. We posit that the enhancement of multiple aspects of post-stroke gait during FAST-FES suggest that FAST-FES may have potential as a post-stroke gait rehabilitation intervention.
