Tremor is differentiated from other involuntary movement disorders, such as chorea, athetosis, ballism, tics, and myoclonus, by its repetitive, stereotyped movements of a regular amplitude and frequency. Clonus, unlike tremor, represents a rhythmic movement, which is increased by muscle stretching.
