S7 denotes “Serial 7” cognitive task. COWAT denotes a controlled oral word association test; O denotes motor task with circle shape movement track. + denotes a motor task with cross-shaped movement track. *p-value by paired t-test between single and dual task results. ^†p-value by student’s t-test between stroke and control. Bold digits indicate values with statistical significance (p < 0.05).
