Brief Summary:
The purpose of the study is to document long-term response in real-life practice after injection cycles with BoNT-A in subjects suffering from idiopathic cervical dystonia (Long-term clinical and pharmaco-economic data).

Condition or disease Intervention/treatment
Cervical Dystonia Drug: BoNT-A injections, 3-4 times yearly

Study Type : Observational
Actual Enrollment : 1050 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: An International Observational Prospective Study On Long-Term Response To Botulinum Toxin Type A (BoNT-A) Injections In Subjects Suffering From Idiopathic Cervical Dystonia (CD) - Pharmaco-Economic Impact
Actual Study Start Date : December 2012
Actual Primary Completion Date : September 2017
Actual Study Completion Date : September 25, 2017


Group/Cohort Intervention/treatment
Idiopathic cervical dystonia
Adults subjects from Hospitals, Private Practices suffering idiopathic cervical dystonia.
Drug: BoNT-A injections, 3-4 times yearly



Primary Outcome Measures :
  1. Change in subject's satisfaction using a 5-point Likert scale. [ Time Frame: Baseline and at every 3 to 4 months, up to 3 years. ]
    Identification of prognostic factors for subject's satisfaction regarding control of symptoms associated with idiopathic CD.


Secondary Outcome Measures :
  1. Change from baseline in Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) total score and severity sub-scale. [ Time Frame: Baseline and at every 3 to 4 months, up to 3 years. ]
    Assessment of severity of CD.

  2. Change in tremor associated with CD using Tsui score [ Time Frame: Baseline and at every 3 to 4 months, up to 3 years. ]
  3. Change in pain relief assessed using the TWSTRS pain sub-scale. [ Time Frame: Baseline and at every 3 to 4 months, up to 3 years. ]
  4. Change in disability will be measured with the TWSTRS disability sub-scale. [ Time Frame: Baseline and at every 3 to 4 months, up to 3 years. ]
  5. Pharmaco-economic endpoints [ Time Frame: Baseline and at every 3 to 4 months, up to 3 years. ]
    • Time intervals between injections
    • Changes in concomitant treatments for CD and associated symptoms.
    • Changes in employment status
