tDCS blinding questionnaire data
fatigue, scalp irritation, itching, burning sensation, headache
MINOR
Only minor side effects were reported following tDCS, including headache, scalp irritation, tingling, itching, burning sensation, and fatigue. Friedman’s ANOVA revealed no significant differences in these variables between the four protocols (all p values ≥ 0.056) suggesting that participants were sufficiently blinded to which type of stimulation they were receiving.
