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

Estimated Enrollment: 400
