"Naturalization" of the alien hand: case report.

The alien hand syndrome is an involuntary motor phenomenon that occurs infrequently and mostly in stroke patients. A case is reported of a 67-year-old man with left hemiparesis whose hand crept and crawled, especially at night, which caused him to awaken by grasping his collar. The disturbing nocturnal activity of the hand was stilled by placing it in a common oven mitt.
