S7 denotes “Serial 7” cognitive task. COWAT denotes; O denotes a motor task with circle shape movement track. +, denotes a motor task with cross-shaped movement track; Bold, significant p-value (p < 0.05). ^∗p-value by paired t-test between single and dual task results. ^†p-value by student’s t-test between stroke and control.
