Dystonia[edit | edit source]
Dystonia is a movement condition in which muscles contract involuntarily, resulting in repeated or twisting motions. The disorder can affect one area of your body (focal dystonia), two or more neighbouring sections (segmental dystonia), or your entire body (global dystonia) (general dystonia).[1]
Dystonia Rating Scale[edit | edit source]
Objective[edit | edit source]
To measure dystonia and assess the level of the problem.
Background[edit | edit source]
Although several rating systems have been used to measure dystonia, only a few have had their clinimetric features tested. A task group was formed by the Movement Disorders Society to assess existing dystonia grading scales and place them in a clinical and clinimetric framework.
Types of Dystonia Rating Scale[edit | edit source]
Classification of the rating measures applied in studies of dystonia.[2]
Table 1[edit | edit source]Classification of the rating measures applied in studies of dystonia.
Notes: a“Specific” indicates a measure developed specifically for dystonia, “generic” indicates a measure applicable across different diseases, including dystonia; bCriteria are as follows: 1 used in dystonia patients, 2 used by researchers beyond original developers, 3 successful clinimetric testing. |

Abbreviations[edit | edit source]
BoNT | botulinum neurotoxin |
BSDI | Blepharospasm Disability Index |
CDIP-58 | Cervical Dystonia Impact Scale |
CDQ-24 | Craniocervical Dystonia Questionnaire |
FMDRS | Fahn-Marsden Dystonia Rating Scale |
HRQoL | Health-related quality of life |
TWSTRS | Toronto Western Spasmodic torticollis Rating Scale |

Limitations[edit | edit source]
Although none of the measures evaluated are acceptable or sufficient for diagnosing a specific dystonia type (e.g., certain forms of focal or generalised dystonia, paroxysmal dystonia, etc. ), they can be used to rate severity and compare patient groups. Because most dystonia scales evaluate specific body regions, they should only be used on patients who are well-defined and homogeneous. The CDQ-24, for example, has been used in individuals with segmental and generalised dystonia to assess the impact of craniocervical dystonia on quality of life. However, because this scale is exclusive to craniocervical dystonia, using it in individuals with dystonia affecting other parts of the body could lead to inaccurate results.
