功能性电刺激 (FES) 作为一种增强中风后手臂和手部功能性运动的机制已显示出潜力。然而，结合自愿努力和 FES 的神经假体必须考虑限制运动的共同激活模式（协同作用）。本研究的目的是探索在什么条件下可以将自愿努力和 FES 结合起来，以在不同受试者中实现有效的伸展和手部张开。受试者执行伸手和张手任务，其中应用不同水平的自愿努力和 FES 来产生伸手和张手，同时测量由此产生的手部张开和距目标的距离。初步结果表明，参与者之间存在显着差异，以及在仍能有效伸展和张开手的情况下可以付出多少努力。
Functional Electrical Stimulation (FES) has shown potential as a mechanism to augment functional arm and hand movement after stroke. However, neuroprostheses that combine voluntary effort and FES must account for co-activation patterns (synergies) that limit movement. The goal of this study is to explore the conditions under which voluntary effort and FES can be combined to achieve useful reach and hand opening in different subjects. Subjects performed a reach and hand opening task where different levels of voluntary effort and FES were applied to produce reach and hand opening while measuring the resulting hand opening and distance from a target. Initial results indicate that there are significant variations between participants and how much effort can be exerted while still eliciting effective reach and hand opening.
