Hand tremor

A tremor is an involuntary movement or shaking of any body part (even your head or voice may be involved). It is often most noticeable in your hands. There are three main types of tremors:

• Resting or static tremors occur when your hand or affected body part is at rest.
• Kinetic tremors, including intention tremors, occur when you are moving your hand or affected body part and disappear at rest.
• Postural tremors occur when you are holding your hand or affected body part in a particular position for a period of time.
