Task completion refers to the general outcome of the experiment. Only a subset of patients (indicated by bold font) who could complete the task was included in the analysis. Other patients were unable to rest or complete the task.
MACS = Manual Ability Classification System, BFM = Burke-Fahn-Marsden dystonia rating scale, LA = Less affected, MA = More affected, D = Dominant, ND = Non-dominant, MCA = Middle cerebral artery, ACA = Anterior cerebral artery, R = Right, L = Left, EMG = Electromyogram, HV = Healthy volunteers
