Tremor is defined as a rhythmic, involuntary, oscillating movement of a body part occurring in isolation or as part of a clinical syndrome. In clinical practice, characterization of tremor is important for etiologic consideration and treatment. Common types include resting tremor, postural tremor, kinetic tremor, task-specific tremor, and intention tremor. Resting tremor occurs when a body part is at complete rest against gravity. Postural tremor occurs during maintenance of a position against gravity and increases with action. Tremor amplitude decreases with voluntary activity. Action or kinetic tremor occurs during voluntary movement. Box 2 lists examples of postural and action tremors. Task-specific tremor emerges during a specific activity. Intention (or terminal) tremor manifests as a marked increase in tremor amplitude during a terminal portion of targeted movement.
