A 57-year-old right-handed man complained of difficulty using his hands post-coronary artery bypass graft (figure). Neurologic examination revealed signs of callosal disconnection without hemiparesis. When asked to perform limb gestures like "brush your teeth" or "wave goodbye," the right hand performed flawlessly whereas the left hand was severely apraxic (video on the Neurology Web site at www.neurology.org).
一位 57 岁的右利手男性患者在冠状动脉旁路移植术后（如图）主诉双手活动障碍。神经科查体发现胼胝体分离体征，但无偏瘫。当要求患者完成“刷牙”或“挥手再见”等肢体手势时，右手表现完美，但左手严重失用（详见 Neurology 网站 www.neurology.org 上的视频）。
