Overall atDCS effect and reliability across consecutive sessions. A) Combined session average of MEP amplitude (mV) for each time point (Pre, Post0, Post15, Post30) and condition (2mA, 1mA, sham). Two-way ANOVARM was performed with CONDTION and TIME, comparing pre with post-values. Post-hoc pairwise comparisons were performed using Bonferroni correction (*, p≤0.05; **, p≤0.01; ***, p≤0.001). B) Mean MEP amplitudes for each session and condition across time. ICC, calculated with all post-time points from the 3 sessions for each condition (n = 9/condition), showed fair to high reliability. Errors bars represent SEM.
