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.
本病例报告描述了一名截肢者（患者A.S.，一名60岁的男性前肢截肢者），他对幻肢有非凡的体验。他抱怨说，他无法移动幻肢的手腕，因为感觉有一根金属棒被手抓住了。作为移除金属棒的解决方案，我们邀请患者接受镜像反射诱导的视觉反馈疗法。患者报告说，在治疗过程中，先前被他手抓住的金属棒已成功从幻肢中移除。有趣的是，这一体验伴随着残留手腕肌肉中肌电图调制的深刻变化。在本文中，将讨论这一有趣现象背后的可能机制。
