Overview Of Tremor

A tremor is a rhythmic shaking movement in one or more parts of your body. It is involuntary, meaning that you cannot control it. This shaking happens because of muscle contractions.

A tremor is most often in your hands, but it could also affect your arms, head, vocal cords, trunk, and legs. It may come and go, or it may be constant. This condition can happen on its own or be caused by another disorder. There are several types, including

Essential tremor sometimes called benign essential tremor. This is the most common type. It usually affects your hands, but it can also affect your head, voice, tongue, legs, and trunk.

Parkinsonian tremor, which is a common symptom in people who have Parkinson’s disease. It usually affects one or both hands when they are at rest, but it can affect the chin, lips, face, and legs.

Dystonic tremor, which happens in people who have dystonia. Dystonia is a movement disorder in which you have involuntary muscle contractions. The contractions cause you to have twisting and repetitive movements. It can affect any muscle in the body.
