The fitting of upper-extremity amputees requires special efforts, and its significance has been increased by the development of myoelectrically controlled prosthetic arm. Although an artificial hand only represents a relatively modest substitute for the missing hand of human beings, the efforts of designers and the achievements of manufacturers should not go unnoticed. Because of the development of myoelectrically controlled prosthetic arm, the amputee's standard of function can be improved and a cosmetic and functional solution provided. For control of the electromechanical hand, muscular potentials are received from the residual limb surface, amplified in the electrodes, and transmitted as control signals to the distal area. An important factor in providing a successful fitting is a reliable man-machine connection. This article summarizes the historic development and state of the art of the myoelectrically controlled arm prosthesis. The components and technical evaluations of the Myobock system as well as the procedures for fitting and fabricating a below-elbow prosthesis have been improved recently. A critical analysis of adaptive hands suggests that the prospects for the future are good.
上肢截肢者的假肢适配需要付出特殊努力，随着肌电控制假臂的发展，其重要性日益增加。尽管人造手只是对人类缺失手部的一种相对有限的替代，但设计师的努力和制造商的成就不容忽视。由于肌电控制假臂的发展，截肢者的功能标准得以提高，并提供了一种兼具美观与功能的解决方案。为了控制机电手，需从残肢表面接收肌肉电位，在电极中进行放大，然后作为控制信号传输到远端区域。实现成功适配的一个重要因素是可靠的人机连接。本文总结了肌电控制手臂假肢的历史发展和现状。Myobock系统的组件、技术评估以及肘下假肢的适配和制作程序最近都有所改进。对自适应手的批判性分析表明，未来前景良好。
