choreoathetosis /kôr′ē·ō·ath′ətō″sis/ [Gk, choreia, dance, athetos, not fixed] , irregular involuntary movements that may involve the face, neck, trunk, extremities, or respiratory muscles, giving an appearance of restlessness. The writhing movements may vary from subtle to wild and ballistic and are commonly associated with administration of levodopa in parkinsonism. Levodopa-induced involuntary movement (dyskinesia) occurs most commonly 1 to 3 hours after administration of the drug.
