Dyskinesia

Dyskinesia refers to a category of movement disorders that are characterized by involuntary muscle movements,^[1] including movements similar to tics or chorea and diminished voluntary movements.^[2] Dyskinesia can be anything from a slight tremor of the hands to an uncontrollable movement of the upper body or lower extremities. Discoordination can also occur internally especially with the respiratory muscles and it often goes unrecognized.^[3] Dyskinesia is a symptom of several medical disorders that are distinguished by their underlying causes.
