Time Perspective: Prospective
Official Title: Factors Influencing Response to One BoNT-A Injection Cycle in Subjects Suffering From Idiopathic Cervical Dystonia
Study Start Date : February 2009
Actual Primary Completion Date : February 2010
Actual Study Completion Date : April 2010





Primary Outcome Measures :
  1. Responder rate at peak effect following one BoNT-A injection cycle without any deviations from routine practice [ Time Frame: Around 4 weeks post injection ]

Secondary Outcome Measures :
  1. To describe TWSTRS change scores from inclusion (total score & subscales scores) [ Time Frame: Baseline, and around 4 weeks and 3 months post injection ]
  2. To describe tremor change score from inclusion (TSUI scale) [ Time Frame: Baseline, and around 4 weeks and 3 months post injection ]
  3. To describe the Cervical Dystonia Impact Profile (CDIP) 58 change from inclusion [ Time Frame: Baseline, and around 4 weeks post injection ]
  4. To describe subject and investigator's CGI scores [ Time Frame: Around 4 weeks post injection ]
  5. To identify prognostic factors for response (Exploratory Objective) [ Time Frame: baseline, and around 4 weeks and 3 months post injection ]
