Dystonia Rating Scale

Dystonia[edit | edit source]

Medically induced dystonia

Dystonia is a hyperkinetic movement disorder in which involuntary contractions of muscles occur. It is characterised by sustained muscle contractions and abnormal trunk, neck, face, arms, and legs postures.[1] Dystonia Rating Scales (DRS) aim to evaluation the severity and distribution of motor symptoms and how they affect an individuals life. and also give a reference point for post-treatment evaluations. These tools provide an objective outcome, and need be accurate and of high quality.[2]

Dystonia Rating Scale[edit | edit source]

A task force that looked into DRS advocated the use of seven specific dystonia scales.

  1. One scale rating blepharospasm, the Blepharospasm Disability Index (BSDI)
  2. Two scales rating cervical dystonia , the Cervical Dystonia Impact Scale (CDIP-58) and the Toronto Western Spasmodic torticollis Rating Scale (TWSTRS)
  3. One scale rating blepharospasm and cervical dystonia, the Craniocervical Dystonia Questionnaire (CDQ-24)
  4. Two scales rating laryngeal dystonia, the Voice Handicap Index (VHI) and the Vocal Performance Questionnaire (VPQ)
  5. One scale rating generalized dystonia the Fahn-Marsden Dystonia Rating Scale (FMDRS). [2]
