This paper presents the design and preliminary experimental verification of a multigrasp myoelectric controller. The controller enables the direct and proportional control of a multigrasp transradial prosthesis through a set of nine postures using two surface EMG electrodes. Five healthy subjects utilized the multigrasp controller to manipulate a virtual prosthesis to experimentally quantify the performance of the controller in terms of real time performance metrics. For comparison, the performance of the native hand was also characterized using a dataglove. The average overall transition times for the multigrasp myoelectric controller and the native hand with the dataglove were found to be 1.49 and 0.81 seconds, respectively. The transition rates for both were found to be the same (99.2%).
本文介绍了一种多抓握肌电控制器的设计及初步实验验证。该控制器通过两个表面肌电电极,利用一组九个姿势实现对多抓握经桡侧假肢的直接和比例控制。五名健康受试者使用多抓握控制器操纵虚拟假肢,以根据实时性能指标对控制器的性能进行实验量化。为作比较,还使用数据手套对自然手的性能进行了表征。结果发现,多抓握肌电控制器和佩戴数据手套的自然手的平均总体转换时间分别为1.49秒和0.81秒。两者的转换率相同(99.2%)。
