- Tremor is an involuntary shaking movement that is repeated over and over. Although it may affect any part of the body, tremor most often affects the hands and head. Your voice may also shake. Sometimes the feet or torso may also shake. Essential tremor, which sometimes runs in families, is one of the most common types of tremor.

Medicine can help reduce the shaking.
