Primary Outcome Measures:
  • Proportion of treatment responders using the Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) severity scale score [ Time Frame: Cycle 1 - Baseline and week 4 ]
  • Patient Global Impression of Change using the 7-point Likert scale [ Time Frame: Cycle 1 - Baseline and week 4 ]

Secondary Outcome Measures:
  • Clinical Global Impression of Change using the 7-point Likert scale [ Time Frame: Cycle 1 - Week 4 and early termination visit ]
  • Patient Global Impression of Change using the 7-point Likert scale [ Time Frame: Cycle 1 - Week 4; Cycles 2 to 4 - Baseline, week 4 and termination visits ]
  • Time to Waning Effect of Dysport treatment/symptom re-emergence [ Time Frame: Cycles 1 to 4 - Week 8 and at study termination visits ]
  • Patient-self-administered questionnaire (Cervical Dystonia Impact Profile-58) [ Time Frame: Cycles 1 & 3: Baseline ]
  • Patient-reported assessment of pain using the Pain Numeric Rating Scale (NRS) [ Time Frame: Cycles 1 to 4 - Baseline, week 4 and at study termination visits ]
  • Treatment Satisfaction Questionnaire for Medication (TSQM) [ Time Frame: Cycle 1 - Week 4; Cycles 2 to 4 - Baseline, week 4 and termination visit ]

Study Population
Adult patients with Cervical Dystonia treated with Dysport

Inclusion Criteria:

  • A diagnosis of idiopathic CD as determined by the enrolling investigator
  • If previously treated with a neurotoxin for CD, at least a 12-week interval must have elapsed between the last injection of Botulinum toxin A (BoNT-A) or Botulinum toxin B (BoNT-B) and the first dose of Dysport injected in this study
  • Patient is able to comply with the protocol (e.g., can visit the clinic as required and can complete questionnaires/telephone interviews)
  • Provision of written informed consent prior to enrollment

Exclusion Criteria:

  • Contraindications to treatment with any BoNT-A or BoNT-B preparations
  • Based on Investigator opinion, patients in whom previous BoNT-A or BoNT-B therapy has failed to produce a clinical response or produced an intolerable adverse reaction
  • Anticipated concomitant treatment with BoNT for other than cervical dystonia
  • Secondary cervical dystonia
