Abstract
For quantitative assessment of the primary torsion dystonias, a rating scale is proposed that has two sections—a Movement Scale, based on examination, and a Disability Scale, based on the patient's statements about seven activities of daily living. We assessed the validity of the Movement Scale by comparing scores with a ranking of patients according to dystonia severity and with ratings of the patients on the Disability Scale. In addition, we assessed the inter-and intra-rater reliability of the scale by comparing independent scorings of patients by four examiners and by comparing scorings by the same examiners performed at different times. We found that the Movement Scale was a valid and reliable indicator of the severity of primary torsion dystonia.
