The alien hand sign refers to a group of signs which include a feeling that the hand is foreign together with autonomous activity, as if the hand is driven by an external agent. These features are commonly associated with frontal and callosal lesions. We report the alien hand sign in a man with left medial cortical infarct, presenting with autonomous grasping and groping with his right upper limb, denial of ownership of his limb, and dissociative phenomena including self restriction and intermanual conflict.
异己手征指的是一组体征，包括感觉手是外来的以及自主活动，就好像手是由外部因素驱动的。这些特征通常与额叶和胼胝体病变有关。我们报告了一名患有左侧内侧皮质梗死的男性出现异己手征的病例，其表现为右上肢自主抓握和摸索、否认肢体的所属感以及包括自我限制和双手冲突在内的分离现象。
