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.
功能性电刺激（FES）或许能够增强中风后手臂和手部的功能性运动。然而，将自主努力与FES相结合的神经假体必须考虑多个关节共有的协同收缩模式（协同作用）。本研究的目的是确定自主努力与FES相结合以实现有效伸展和手部张开的原则。进行了一项伸展和手部张开任务，在测量手部FES能够产生的手部张开程度的同时，施加不同水平的自主努力和FES以实现伸展。初步结果表明，低水平的自主努力既能实现更大程度的伸展，又能使手部对FES产生最大的张开反应。
