What are the most important abnormal involuntary movements?
They are tremors, fibrillations, fasciculations, chorea, athetosis, hemiballismus, myoclonus, dystonias, tics,
asterixis, and seizures.
Tremors: Rhythmic muscular oscillations around a joint, to-and-fro or up-and-down
Fibrillations: Not visible to the naked eye except possibly those in the tongue
Chorea: One of many writhing and twisting motions, which also include athetosis and hemiballismus
Myoclonus: A sudden and brief (<0.25 second) muscle jerk, shock-like, with twitching of a joint;
often asymmetric; isolated or in association with hypoxic encephalopathy/epilepsy
Dystonia: A persistent, fixed contraction of a muscle —such as torticollis or wry neck
Seizures: May result in automatisms of the face or limbs, repeated eye blinks, or tonic-clonic activity
