关于第二部分，见同上，第37卷，第11号。pp. 1037-1047，1990年11月）。提出了一种新的控制方案，截肢者命令肘关节假肢使用肌电活动。通过模仿完整的神经肌肉系统的一些重要特征，所提出的控制器试图使假肢作为自然肘关节来响应截肢者的自愿命令和来自环境的施加力矩。还介绍了一种新的实验功能评估肘关节假体控制器的描述。实验设计要求截肢者在操作能够实现各种控制器的假肢的同时执行受约束的运动任务。由于约束的性质，任务强调假体对两种输入的反应：自愿命令和外部力矩。
For Pt II see ibid. vol. 37, no. 11. pp. 1037-1047, Nov. 1990). A novel control scheme by which an amputee commands an elbow prosthesis using myoelectric activity is presented. By mimicking some important characteristics of the intact neuromuscular system, the proposed controller attempts to make the prosthesis respond as the natural elbow to both voluntary commands from the amputee and applied moments from the environment. Also presented is a description of a novel experiment for functionally assessing elbow prosthesis controllers. The experimental design calls for an amputee to perform a constrained motion task while operating a prosthesis capable of implementing a wide variety of controllers. Due to the nature of the constraint, the task emphasizes the prosthesis response to both inputs: voluntary commands and external moments.
