本病例报告描述了一名截肢者（患者A。美国，一个60岁的男性前肢截肢者），他有一个非凡的幻肢经历。他抱怨说，他无法移动幻肢的手腕，因为他的手感觉到一根金属棒被抓住了。作为移除金属棒的解决方案，我们邀请患者接受镜面反射诱导的视觉反馈治疗。患者报告称，在治疗过程中，之前用手抓住的金属棒成功从体模中取出。有趣的是，这种经历伴随着残留腕部肌肉的EMG调制的深刻变化。在这篇文章中，将讨论这一有趣现象背后的可能机制。
This case report describes an amputee (patient A. S., a 60-year-old male forelimb amputee) who had an extraordinary experience with a phantom limb. He complained that he could not move the wrist of his phantom limb because a metal bar was perceived to be grasped by the hand. As a solution for removing the metal bar, we invited the patient to undergo mirror reflection-induced visual feedback therapy. The patient reported that the metal bar previously grasped by his hand was successfully removed from the phantom during the course of therapy. Interestingly, this experience was accompanied by profound changes in the EMG modulation in the residual wrist muscles. In this article, the possible mechanisms underlying this interesting phenomenon will be discussed.
