We describe a case of hereditary congenital mirror movements (MMs) in a 76-year-old man, who after an ischemic stroke, had persistence of MMs in the paretic hand during voluntary movements of the contralateral arm. By using functional MR imaging to investigate the performance of motor and sensory tasks with the affected and the unaffected hands, we found evidence for increased ipsilateral primary motor cortex activity and reduced transcallosal inhibition. Both these mechanisms are likely to be involved in the genesis of MMs.
我们描述了一例76岁男性的遗传性先天性镜像运动（MMs）病例，该患者在缺血性中风后，对侧手臂进行自主运动时，患侧手部的MMs持续存在。通过使用功能磁共振成像来研究患手和未患手在运动和感觉任务中的表现，我们发现同侧初级运动皮层活动增加和胼胝体抑制减弱的证据。这两种机制可能都参与了MMs的发生。
