General tDCS effects
itching, fatigue, pain
HEAT, SIDE EFFECT
The frequency and severity of reported side effects (i.e., itching, pain, burning, heat, metallic taste, and fatigue) were assessed for the last experimental session. None of the participants reported metallic taste as a side effect in atDCS or sham tDCS. Two-sided Fisher exact tests revealed no association between the frequency of reported side effects and type of stimulation (atDCS and sham tDCS), all Severity ratings of experienced side effects after the last experimental session.
