Clinical Trial Summary

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.
