Objective. Artificial proprioceptive feedback from a myoelectric prosthesis is an important aspect in enhancing embodiment and user satisfaction, possibly lowering the demand for visual attention while controlling a prosthesis in everyday tasks. Contemporary myoelectric prostheses are advanced mechatronic systems with multiple degrees of freedom, and therefore, to communicate the prosthesis state, the feedback interface needs to transmit several variables simultaneously. In the present study, two different configurations for conveying proprioceptive information of wrist rotation and hand aperture through multichannel electrotactile stimulation were developed and evaluated during online myoelectric control. Approach. Myoelectric recordings were acquired from the dominant forearm and electrotactile stimulation was delivered on the non-dominant forearm using a compact interface. The first feedback configuration, which was based on spatial coding, transmitted the info...

用于两个自由度的肌电控制的幅度与空间调制电触觉反馈。

目的。来自肌电假体的人工本体感受反馈是增强实施例和用户满意度的重要方面，可能在控制日常任务中的假体时降低视觉注意力的需求。当代的肌电假体是具有多个自由度的先进的机电一体化系统，因此，为了传达假体状态，反馈接口需要同时传输多个变量。在本研究中，开发了两种不同的配置，用于通过多通道电触觉刺激传递手腕旋转和手孔的本体感受信息，并在在线肌电控制期间进行了评估。方法。从优势前臂获取肌电记录，并使用紧凑接口在非优势前臂上传递电触觉刺激。第一个基于空间编码的反馈配置传输了信息...
