Study:
Natural History and Biospecimen Repository for Dystonia; Comprehensive Rating Tools for Cervical Dystonia; Validity & Reliability of Diagnostic Methods & Measures of Spasmodic Dysphonia
Rationale:

Purpose:
Dystonia is a disorder characterized by excessive involuntary contraction of muscles with
repetitive and patterned movements. The primary focal dystonias are the most common type of
dystonia and include Limb dystonias (like writer`s cramp), Cervical dystonia (spasmodic
torticollis), Laryngeal dystonias (like spasmodic dysphonia), and Craniofacial dystonias
(like blepharospasm). The purpose of this study is to create resources to help learn more
about the primary focal dystonias and to develop and validate various dystonia rating
scales.
