功能性电刺激(FES)是恢复瘫痪患者功能性运动的一种有前途的解决方案，但利用FES实现各种所需任务的全臂伸展运动的潜力尚未实现。我们提出了一种开环控制器，能够计算和应用必要的肌肉刺激来将高位四肢瘫痪患者的手腕固定在任何想要的位置。我们使用控制器将手腕保持在一系列静态位置。该控制器能够区分不同的手腕位置。到目标手腕位置的平均距离或准确度为7.7厘米。在相同肌肉刺激或精确度的一组试验中，95%可信椭球的平均半径为6.7厘米。添加反馈或在线模型更新可能会提高需要更精细控制的任务的准确性。该控制器是使用FES控制全臂运动的良好第一步。
Functional electrical stimulation (FES) is a promising solution for restoring functional motion to individuals with paralysis, but the potential for achieving full-arm reaching motions with FES for various desired tasks has not been realized. We present an open-loop controller capable of calculating and applying the necessary muscle stimulations to hold the wrist of an individual with high tetraplegia at any desired position. We used the controller to hold the wrist at a series of static positions. The controller was capable of discriminating between different wrist positions. The average distance to the target wrist position, or accuracy, was 7.7 cm. The average radius of the 95% confidence ellipsoid for a set of trials with the same muscle stimulations, or precision, was 6.7 cm. Adding feedback or online model updates will likely improve the accuracy for tasks requiring finer control. The controller is a good first step to controlling full-arm motions with FES.
