使用触觉显示来参考从假肢终端设备以电子方式感测到的提示，有望改善肌电控制的上肢假肢的功能。这种承诺经常在涉及非截肢者的实验中进行评估，尽管来自完整手的额外触觉反馈（辅助反馈）的可用性可能会混淆使用非截肢者作为截肢者的替身的尝试。在本文中，我们测试的辅助触觉反馈肌电控制性能的影响，通过引入各种把握条件下的补偿跟踪任务。我们要求非截肢者通过产生肌电控制信号来补偿随机信号的运动，这些信号具有硬物体，软物体或没有物体（需要共同收缩）。错误信号通过佩戴在上臂上的挤压带或视觉显示器显示。我们的研究结果表明，触觉和视觉反馈跟踪之间的主要区别是低频漂移，辅助反馈并没有实质性地影响任务性能。尽管漂移，我们的研究结果表明，参与者能够响应提示通过挤压带在补偿跟踪任务。
The use of haptic display to refer cues sensed electronically from a prosthetic terminal device promises to improve the function of myoelectrically controlled upper limb prostheses. This promise is often evaluated in experiments involving non-amputees, though the availability of additional haptic feedback from an intact hand (auxiliary feedback) may confound attempts to use non-amputees as stand-ins for amputees. In this paper we test the influence of auxiliary haptic feedback on myoelectric control performance by introducing various grasp conditions in a compensatory tracking task. We ask non-amputees to compensate for the motion of a random signal by producing myoelectric control signals with a hard object, soft object, or no object (requiring co-contraction) in their grasp. The error signal is displayed through a squeeze band worn about the upper arm or a visual display. Our results suggest that the main difference between tracking with haptic and visual feedback is low-frequency drift, and that auxiliary feedback does not substantially influence task performance. Despite the drift, our results show that participants are able to respond to cues presented through the squeeze band in the compensatory tracking task.
