Torsion dystonia

Torsion dystonia, also called dystonia musculorum deformans, is a disease marked by painful muscle contractions that produce uncontrollable distortions of the body. It is a specific type of dystonia and is frequently found in children, with symptoms commonly starting around the ages of eleven or twelve. The contractions typically begin in one general area, such as an arm or a leg, and then continue to progress through the rest of the body. According to the source, it takes roughly five years for the symptoms to advance fully to a debilitating state.
