Tremor type. The subsequent exam should further delineate the tremor type. An action tremor is usually
exhibited when the body part is moved from one point to another (kinetic tremor), with muscle contraction
against a fixed object (isometric tremor), and or when writing or performing other specific activities (task-
specific tremor). The typical frequency of an action tremor is between 3 and 10 Hz.
A postural tremor is exhibited when the position of the body part is maintained against gravity. To elicit this type
of tremor, the clinician can simply ask the patient to extend his or her arm or leg, as indicated, and hold it in that
position for a period of time. Essential tremor, the most common type of postural tremor, has a moderate to
high frequency and low amplitude.
A rest tremor, by definition, is exhibited while the affected body part is at rest. The tremor is typically worse
during mental distraction, i.e., during the cognitive assessment while the patient is counting by 7's. A rest
tremor decreases with intentional movement, has a low to moderate frequency (i.e., 3-6 Hz), and has a high
amplitude. The tremor of Parkinson's disease is an example of a rest tremor, although this may also be a mixed
tremor, and 20% of patients with Parkinson's disease have no tremor at the onset of disease.
