本文介绍了一种使用 FES 控制瘫痪人体手臂伸展运动的准静态方法。根据从使用功能性电刺激神经假体的高位颈髓损伤的单个受试者收集的实验数据来估计受试者特定模型。我们测试了基于该模型的控制器，该控制器将所需的肩关节和肘关节位置映射到肌肉刺激命令。控制器可以很好地跟踪手部运动所需的横向方向，但不能很好地跟踪向前/向后或垂直运动。给出相同的刺激命令时，手的横向位置并没有受到运动方向的很大影响，这支持了跟踪缓慢的手运动不需要速度信息的假设。
This paper introduces a quasi-static method for controlling reaching movements of a paralyzed human arm using FES. A subject-specific model was estimated from experimental data collected from a single subject with a high cervical spinal cord injury who uses a functional electrical stimulation neuroprosthesis. We tested a controller based on this model that maps desired shoulder and elbow joint positions to muscle stimulation commands. The controller tracked the desired lateral direction of hand movements well but did not track forward/backward or vertical movements well. The lateral position of the hand was not greatly affected by the direction of movement given identical stimulation commands, which supports the hypothesis that velocity information is not required for tracking slow hand movements.
