Introduction
Tremor is a rhythmic movement of a portion of the
body such as the arm, hand, leg, head, voice, or trunk which varies in
size but has a relatively constant frequency for an individual patient.
Tremor is the most common of all disorders causing involuntary
movements. It also occurs from time to time in most normal individuals
in the form of an exaggerated physiologic tremor.
