Movement Disorder Survey in East China
Movement Disorder Survey in East China
Movement disorder involve recurring or constant muscle contractions causing squeezing or
 twisting movement, such as hemifacial spasm, blepharospasm, cervical dystonias etc. The most
 common focal dystonia was cervical dystonia in western countries according to previous
 studies, which is different from China in Chinese neurologists' opinion. And there is no such
 survey. So the investigators are conducting a movement disorder survey in east China to
 confirm it.
