Convulsive syncope

Syncopal episodes may be followed by myoclonus or synchronous or asynchronous jerking. In this video a young woman has a syncopal event elicited by hyperventilation and rapid standing in a controlled environment.

Eastchester Clapping sign

Hand clapping is a motor program mastered in infancy. A patients with hemispatial neglect who, when asked to clap, repeatedly performed one-handed motions stopping abruptly at the midline of the visual hemispace, as if pantomiming slapping an invisible board. In contrast, hemiplegic patients without neglect will reach across and clap against their plegic hands. This phenomenon provides an easy, rapid, and unambiguous test for neglect, applicable to patients of any ethnicity or age.
