The FMDRS was originally established for the clinical assessment of primary torsion dystonia in adults Subthalamic nucleus deep brain stimulation for severe idiopathic dystonia: Scales need to be evaluated in different populations such as in children versus adults, and primary vs.

The task force recommends the five specific dystonia scales and suggests to further validate in dystonia the two recommended generic voice-disorder scales. Materials and methods Administrative organization and critique process The MDS Task Force on Rating Scales for Movement Disorders Steering Committee invited the chairman AA to form a task force to critique existing dystonia rating scales and to place them in a clinical and clinimetric context.

Botulinum toxin treatment of adductor spasmodic dysphonia: The CDQ has been used by multiple groups to measure the impact on quality of life of focal, segmental and even generalized dystonia 16 and also as a HRQoL measure to assess responsiveness to treatment-induced changes 60 Long-term effects of pallidal deep brain stimulation in tardive dystonia. Bilateral deep brain stimulation for cervical dystonia: Scale application in dystonia The CDQ has been specifically developed for patients with craniocervical dystonia, who had both cervical dystonia and blepharospasm.

Clinical assessments of patients with cervical dystonia. Warner9 Albert F. Then the task force members selected the scales to be included in the review see criteria below and identified unresolved issues and limitations of the critiqued scales.

Each of these scales has been shown to have specific advantages and limitations in dystonia and all have been shown to have adequate clinimetric properties for the assessment of dystonia. Subthalamic nucleus deep brain stimulation in primary cervical dystonia.


Eight scales were excluded, because evaluating secondary dystonia, requiring measurement devices, or dystonai no potential use in dystonia. Double-blind, randomised, parallel group pilot study comparing two botulinum toxin type A products for the treatment of blepharospasm.

Arch Otolaryngol Head Neck Surg. Strengths buurke weaknesses The CDQ is cahn brief and easy instrument. The total movement FMDRS sub-score is provided by the sum of the products of the provoking, severity and weighting factors. Eight were excluded because they did not meet review criteria, leaving twenty-eight scales that were critiqued and rated by the task force.

Dystonia is one of the most common movement disorders, with an overall prevalence of Thirty six potential scales were identified. None of the reviewed scales is appropriate or sufficient to diagnose a specific dystonia type e. Jinnah has served as a consultant for Psyadon Pharmaceuticals and Savient Pharmaceuticals. Deep brain stimulation is now widely accepted as an effective treatment for children with primary generalized dystonia. Sole use of rxting measures, are limited in scope to evaluate outcome following deep brain stimulation, particularly in secondary dystonias.

Vocal Performance Questionnaire VPQ Description of the scale This scale was designed for use in an evaluation study of voice therapy in dystinia of non-organic dysphonia The quality and accuracy of the pre-treatment assessment and the choice of assessment tools are crucial as they will affect all subsequent post-treatment comparisons.

Open in a separate window. Rev Laryngol Otol Rhinol Bord ; Factors predicting improvement in primary generalized dystonia treated by pallidal deep brain stimulation.

Dystonia rating scales: critique and recommendations

The prevalence of primary dystonia: More variable results are reported in secondary dystonias and its efficacy in this heterogeneous group has not been fully elucidated. Jankovic J, Hallett M, editors.


Chronic bilateral pallidal stimulation in patients with generalized primary dystonia – multi-contact cathodal stimulation is superior to bipolar stimulation mode. The VPQ was found to have good internal consistency in a study that included a large range of voice pathologies except for spasmodic dysphonia The pain scale, patient-rated, comprises 3 items including severity, duration and disability due dystonoa pain; the maximal score is Leentjens The author has received research grants from the Michael J Fox Foundation and the Stichting Internationaal Parkinson Fonds, and received compensation for a presentation from Benecke Consultants.

Dystonia rating scales: critique and recommendations

Goetz12 and Anette Schrag 9. Comparison of clinical rating scales in treatment of cervical dystonia with botulinum toxin. Therefore, VPQ still needs further validation in patients with dystonia. Long-term follow-up results of selective laryngeal adductor denervation-reinnervation surgery for adductor spasmodic dysphonia.

Sensitivity to change of self-reported and observer-rated measures. Although only the original German version was validated, an exact translation into English, including back-translation, was performed Botulinum toxin type B de novo therapy of cervical dystonia: Results Thirty mardden scales and questionnaires were identified.

Results Thirty six potential scales were identified. Author manuscript; available in PMC Oct The severity scale, clinician-rated, is composed of 11 items that assess head movements, duration of symptoms, effects of sensory tricks, shoulder elevation and anterior displacement, range of marsdeb, and time in neutral position; the maximal score is Finally, there is a need for uniform training by developing manuals and training tools for dystonia scales.
