Proposal SummaryThe current software and hardware in myoelectric control for powered limb prostheses are limited to sequential and, typically, on/off function selection. This is due, in part, to the nature of the available prosthesis terminal devices in that they are limited in number of functions and dexterity. This is rapidly changing due to increasing numbers of amputees and demand for much improved dexterity. Multifunction prostheses with increased capability are becoming available, and are expected to make marked and rapid improvements. This change must be accompanied by the development of improved controllers to take advantage of the functionality. Myoelectric control has a major role to play in this regard and to this end our research has recently been directed to the development of myoelectric controllers for simultaneous and proportional control of multifunction prostheses. Considerable progress has been made, however there is a need to extend the results to allow dynamic muscle contractions on behalf of the prosthesis user, to decrease the number of electrodes required, to increase the control performance, and to reduce control performance degradation due to crosstalk between myoelectric channels. These improvements will make the prosthesis controller more user friendly, and the prosthesis easier to fabricate.

建议摘要目前的软件和硬件在肌电控制的动力假肢是有限的顺序，通常，开/关功能选择。这部分是由于可用的假体终端装置的性质，因为它们在功能和灵活性方面受到限制。由于截肢人数的增加和对更好的灵活性的需求，这种情况正在迅速改变。具有更高性能的多功能假肢正在出现，并有望取得显著和迅速的改进。这种变化必须伴随着改进的控制器的开发，以利用功能。肌电控制在这方面发挥了重要作用，为此，我们的研究最近一直致力于开发肌电控制器，用于多功能假肢的同步和比例控制。已经取得了相当大的进展，然而，需要扩展结果以允许代表假体用户的动态肌肉收缩，以减少所需的电极数量，以增加控制性能，并减少由于肌电通道之间的串扰而导致的控制性能下降。这些改进将使假肢控制器更加用户友好，假肢更容易制造。
