Figure 4From: Facilitation of corticospinal excitability by virtual reality exercise following anodal transcranial direct current stimulation in healthy volunteers and subacute stroke subjectsAttention and fatigue scales between conditions. Level of attention and fatigue was presented by VAS, from 1: ‘no attention’ to 7: ‘highest level of attention’ and from 1: ‘no fatigue’ to 7: ‘highest level of fatigue’. Error bars indicate SEM. P values were from ANOVA and t-test (**P < 0.01, *P < 0.05). VR: virtual reality, tDCS: transcranial direct current stimulation, VAS: visual analog scale.Back to article page
