In this episode of Extraordinary People, a group of people suffer from a rare condition called Dystonia. Dystonia is a neurological muscle disorder that causes uncontrollable, painful spasms anywhere in the body. Although not very well known, it is estimated that there are more than 500,000 people in North America alone that have the disease. This is more than Muscular Dystrophy, Huntington's Disease, and Lou Gehrig's disease combined.
