Abbreviations: CD, cervical dystonia; HC, healthy controls; μ, Mean; SD, Standard deviation; SRT, Saccadic Reaction Time; 10th %tile, 10th percentile of the pro‐saccade distribution (see text).
Summary results for participants CD (n = 8) and HC (n = 11). Shown are the group μ and SD values for each parameter. % Saccades in the gap task with an SRT below a threshold (140 ms, or a subject‐specific threshold). Values shown for leftward and rightward movements.
