Attention | Fatigue | Pain caused by tDCS | |
---|---|---|---|
Anodal | 5.5 ± 0.5 | 3.4 ± 0.6 | 2.5 ± 0.4 |
Cathodal | 5.1 ± 0.5 | 2.4 ± 0.3 | 2.8 ± 0.6 |
Sham | 5.6 ± 0.4 | 3.0 ± 0.5 | 2.3 ± 0.5 |
ANOVA | F = 0.2, p = 0.79 | F = 1, p = 0.39 | F = 0.2, p = 0.8 |
Values (mean ± SEM) depict the subject's choice in a visual analog scale in which 1 represents poorest attention, maximal fatigue, and pain and 7 represents maximal attention, least fatigue, and pain. F and p values originate from separate ANOVAs for each measure comparing the anodal, cathodal, and sham sessions.
