Adverse events during and after stimulation. (a) Mann–Whitney U tests showed a significantly higher incidence of tingling during 6 Hz tACS compared to tRNS (p = 0.039 and U = 184.0) and sham stimulation (p = 0.007 and U = 161.0). (b) There was a significantly higher incidence of tingling during compared to after stimulation for 6 Hz tACS (p = 0.0023 and U = 149.5).
