Results are reported as average values (standard deviation), unless specified differently. p-value: statistical differences between groups (Unpaired t-test or Fisher’s Exact test). NTr-CD: Non-tremor-dominant Cervical Dystonia; Tr-CD: Tremor-dominant Cervical Dystonia; % express the ratio (women/men).

By design, the cohorts for video rating were matched for age, gender, and disease duration.
