Hyperkinesia

 

excessive, violent, involuntary movements that occur in cases of organic and functional disturbances of the nervous system. Hyperkinesia usually accompanies disturbances of the cerebral cortex, subcortical motor centers, or truncal part of the brain. Types of hyperkinesia include athetosis, chorea, Parkinson’s disease, and myoclonia (brief jerking of a muscle or muscle bundle with a lightning-fast pace of contraction).
