Chorea
Ceaseless rapid complex body movements that look well coordinated and purposeful but are, in fact, involuntary. Chorea was thought suggestive of a grotesque dance. The term "chorea" is derived from the Greek word "choreia" for dancing (as is choreography).

n.
a jerky involuntary movement particularly affecting the head, face, or limbs. Each movement is sudden but the resulting posture may be prolonged for a few seconds. The symptoms are usually due to disease of the basal ganglia but may result from drug therapy for parkinsonism or on the withdrawal of phenothiazines. Such movements are characteristic of Huntington's disease, in which they are associated with progressive dementia. See also Sydenham's chorea.
