Shaking (tremor) is defined as a rhythmic, shaking movement of part of the body caused by muscle contractions. It may be caused by a neurological condition known as Essential Tremor, or it may be a symptom of Parkinson's disease.
In clinical studies patients receiving Activa® Tremor Control Therapy have resumed daily life activities that were previously difficult or impossible, such as writing, pouring liquids, feeding, and dressing themselves.
