When a muscle contracts, an electrical signal can be measured on the skin surface. This myoelectric signal has been used for many years as a means of controlling the grasping function of an artificial arm. The research outlined in this proposal will define techniques to extract more information from the surface myoelectric signal. The additional information will then be used in a number of ways. For the myoelectric control application it will be used to develop more advanced control systems that are capable of controlling additional prosthetic limb functions such as wrist rotation, elbow flexion and multiple hand functions. A hybrid control system will be developed that uses this information and the information from force and position sensors within the socket of the artificial limb to allow an amputee to control the movement of these multiple artificial joints in a natural and coordinated manner.

当肌肉收缩时，可以在皮肤表面上测量电信号。 这种肌电信号已经被用作控制人工手臂抓握功能的手段多年。本提案中概述的研究将定义从表面肌电信号中提取更多信息的技术。这些额外的信息将以多种方式使用。 对于肌电控制应用，它将用于开发更先进的控制系统，能够控制额外的假肢功能，如手腕旋转，肘部弯曲和多个手功能。 将开发一种混合控制系统，该系统使用该信息以及来自假肢承窝内的力和位置传感器的信息，以允许截肢者以自然和协调的方式控制这些多个人工关节的运动。
