本文探讨镜像疗法是否改变了人类运动皮层的神经机制。6名健康志愿者参加了活动。该研究调查了镜子治疗的三个主要因素（在镜子中观察手部运动，假设受影响的手的运动想象，以及帮助锻炼假设受影响的手）对人类运动皮层兴奋性变化的影响，以澄清每个因素的贡献。运动想象过程中运动诱发电位（MEP）幅度的增加往往比没有一个更大的镜子。此外，MEP幅度大大增加时，运动辅助。在镜子里观察一只手的动作，可以更容易地以同样的方式移动另一只手。此外，MEP幅度的增加与传入信息和运动想象的协同作用有关。
This article investigates whether or not mirror therapy alters the neural mechanisms in human motor cortex. Six healthy volunteers participated. The study investigated the effects of three main factors of mirror therapy (observation of hand movements in a mirror, motor imagery of an assumed affected hand, and assistance in exercising the assumed affected hand) on excitability changes in the human motor cortex to clarify the contribution of each factor. The increase in motor-evoked potential (MEP) amplitudes during motor imagery tended to be larger with a mirror than without one. Moreover, MEP amplitudes increased greatly when movements were assisted. Watching the movement of one hand in a mirror makes it easier to move the other hand in the same way. Moreover, the increase in MEP amplitudes is related to the synergic effects of afferent information and motor imagery.
