Data for changes in the areas of EMG responses evoked during 5 min periods of application of cathodal and anodal tDCS, during 5 min post-polarization periods and during post-polarization periods following the last polarization. ANOVA one-way analysis of variance was used for data with normal distribution and equal variance (F, value; P, value) while Kruskal–Wallis one-way analysis of variance on ranks was used for data with non-normal distribution (H, value; d.f., degrees of freedom; P, value). n, sample size.
