A '''tremor''' is an involuntary,<ref>{{DorlandsDict|eight/000110470|tremor}}</ref> somewhat rhythmic [[muscle contraction]] and relaxation involving [[neural oscillations|oscillations]] or twitching movements of one or more body parts. It is the most common of all involuntary movements and can affect the hands, arms, eyes, face, head, [[vocal folds]], trunk, and legs. Most tremors occur in the hands. In some people, a tremor is a symptom of another [[neurological disorder]].
