The term cerebellar tremor is often used synonymously with intention tremor. However, several clinical types of action tremor are included in this category with intention tremor being the most common form. Intention tremor typically increases during the approach to a target. Action, kinetic, and titubation or stance tremors are usually regarded as being of cerebellar origin if other signs of cerebellar dysfunction are also present. According to the consensus statement of the Movement Disorder Society on tremor, cerebellar tremors can be diagnosed according to the following clinical signs: (1) pure or dominant intention tremor, either unilateral or bilateral; (2) tremor frequency usually less than 5 Hz; and (3) postural tremor present without rest tremor.
