Chorea

Chorea (or choreia, occasionally) is an abnormal involuntary movement disorder, one of a group of neurological disorders called dyskinesias. The term chorea is derived from the Ancient Greek: χορεία ("dance"; see choreia), as the quick movements of the feet or hands are comparable to dancing.

Not to be confused with Korea or Cholera.
For the ancient Greek dance, see Choreia. For other uses, see Chorea (disambiguation).
