功能性电刺激（FES）可以增强中风后手臂和手的功能运动。然而，结合自主力和FES的神经假体必须考虑多个关节常见的共同收缩模式（协同作用）。本研究的目的是确定自愿努力和FES可以结合的原则，以实现有用的伸手和手张开。在执行伸手和手张开任务时，应用不同水平的自愿努力和FES来产生伸手，同时测量FES可以在手部产生的手张开水平。初步结果表明，低水平的自愿努力可以使手伸向更远的地方，并对FES做出最大的张开反应。
Functional Electrical Stimulation (FES) may be able to augment functional arm and hand movement after stroke. However, neuroprostheses that combine voluntary effort and FES must take into account the co-contraction patterns (synergies) that are common across multiple joints. The goal of this study is to determine the principles under which voluntary effort and FES can be combined to achieve useful reach and hand opening. A reach and hand opening task is performed where different levels of voluntary effort and FES are applied to produce reach while measuring the level of hand opening that FES can produce at the hand. Initial results indicate that low levels of voluntary effort allow both greater reach and the largest hand opening response to FES.
