A useful way to understand and describe tremors is to define them according to the following types. Resting tremor occurs when the muscle is relaxed, such as when the hands are lying on the lap or hanging next to the trunk while standing or walking. It may be seen as a shaking of the limb, even when the person is at rest. Often, the tremor affects only the hand or fingers. This type of tremor is often seen in patients with Parkinson's disease.
