About

Hand tremors are unintentional rhythmic movements of the hand that occur either at rest or with motion.

Tremors are unintentional, rhythmic movements of a part of the body that occur in a back-and-forth pattern. They are the most common of all involuntary movements and can affect the hands, arms, head, face, voice, trunk and legs.
