Action tremor is a rhythmic, oscillatory, and involuntary movement of the limb that is seen with movement of an extremity. It may be seen in isolation with a cerebellar lesion or associated with other tremor types such as the postural tremor of essential tremor or the rest tremor of Parkinson’s disease.
