Dystonia is a neurologic movement disorder that causes uncontrollable muscle contractions in one or more parts of the body. It may affect the face, neck, vocal cords, arms, legs or torso. People living with dystonia are affected in different ways. The severity of the disease varies from person to person. Many people who have dystonia can maintain a relatively normal lifestyle. Others may need full-time assistance. For more medical information on dystonia please visit our "What is Dystonia" page.
