- Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) [ Time Frame: Baseline and Week 4 ]TWSTRS is comprised of three different components which are severity, disability & pain. There is an ordinal scale for each component and the score range for each is the following: for severity from 0 (absence of severity) to 35 (max severity), for disability from 0 (no disability) to 30 (max disability) and for pain from 0 (no pain) to 20 (max pain). TWSTRS total score is the sum of the 3 component scores, with a range from 0 to a maximum of 85. The change in TWSTRS total score is the score at week 4 minus the score at baseline.
- Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) [ Time Frame: Baseline and Week 8 ]TWSTRS is comprised of three different components which are severity, disability & pain. There is an ordinal scale for each component and the score range for each is the following: for severity from 0 (absence of severity) to 35 (max severity), for disability from 0 (no disability) to 30 (max disability) and for pain from 0 (no pain) to 20 (max pain). TWSTRS total score is the sum of the 3 component scores, with a range from 0 to a maximum of 85. The change in TWSTRS total score is the score at week 4 minus the score at baseline.
- Toronto Western Spasmodic Torticollis Rating Scale (TWSTRS) Total Score [ Time Frame: Baseline and Week 12 ]TWSTRS is comprised of three different components which are severity, disability & pain. There is an ordinal scale for each component and the score range for each is the following: for severity from 0 (absence of severity) to 35 (max severity), for disability from 0 (no disability) to 30 (max disability) and for pain from 0 (no pain) to 20 (max pain). TWSTRS total score is the sum of the 3 component scores, with a range from 0 to a maximum of 85. The change in TWSTRS total score is the score at week 4 minus the score at baseline.
- Subject Visual Analogue Score (VAS) for Cervical Dystonia (CD) Symptom Assessment [ Time Frame: Baseline and Week 4 ]The assessment was a continuous 100 mm horizonal line with a scale of 0 mm (no symptoms)to 100 mm (worst possible symptoms).
- Investigator VAS for CD Symptom Assessment [ Time Frame: Baseline and Week 4 ]The assessment was a continuous 100 mm horizonal line with a scale of 0 mm (no symptoms)to 100 mm (worst possible symptoms).
- Subject VAS for CD Symptom Assessment [ Time Frame: Baseline and Week 8 ]The assessment was a continuous 100 mm horizonal line with a scale of 0 mm (no symptoms)to 100mm (worst possible symptoms).
- Investigator's VAS for CD Symptom Assessment [ Time Frame: Baseline and week 8 ]The assessment was a continuous 100 mm horizonal line with a scale of 0 mm (no symptoms)to 100 mm (worst possible symptoms).
- Subject VAS for CD Symptom Assessment [ Time Frame: Baseline and week 12 ]The assessment was a continuous 100 mm horizonal line with a scale of 0 mm (no symptoms)to 100 mm (worst possible symptoms).
- Investigator's VAS for CD Symptom Assessment [ Time Frame: Baseline and week 12 ]The assessment was a continuous 100 mm horizonal line with a scale of 0 mm (no symptoms) to 100 mm (worst possible symptoms).
- SF-36 Mental Health Summary Score [ Time Frame: Week 8 ]SF-36 is a Quality of Life scale comprising eight individual domains. The QoL score for each domain is on a scale from 0 (worst health possible) to 100 (best health possible). SF-36 Mental Health Summary Score is derived from four individual domains (vitality, social functioning, role limitations due to emotional problems and mental health).
- SF-36 Physical Health Summary Score [ Time Frame: Week 8 ]SF-36 is a Quality of Life scale comprising eight individual domains. The QoL score for each domain is on a scale from 0 (worst health possible) to 100 (best health possible). SF-36 Physical Health Summary Score is derived from four individual domains (physical functioning, role physical, bodily pain and general health).
- Number of Participants Considered by the Investigator to be Overall Treatment Successes [ Time Frame: Week 12 ]The number of participants considered to be overall treatment successes by the investigator at week 12 was assessed.
