Common Types of Tremor

Research output: Chapter in Book/Report/Conference proceedingChapter


Tremor is defined as a rhythmic oscillation of one or more body parts. Tremor is typically classified as resting or action tremor. Action tremor, also referred to as "kinetic tremor," is further subdivided into postural and intention tremor and is defined as any tremor that is produced by voluntary contraction of muscle. Postural tremor is present while voluntarily maintaining a position against gravity (e.g., holding up outstretched arms). Intention tremor occurs when tremor increases as one is approaching a target (e.g., with finger-to-nose movements). The differential diagnosis for tremor is vast, including drug-induced tremors, essential tremor, tremors as part of a genetic or neurodegenerative syndrome, or tremors secondary to other medical conditions. The practical aspects of differential diagnosis, treatment approach, and workup are outlined in detail.
