Pre- and post-anodal and sham tDCS values of pain improvement of the Adaptive Visual Analog Scales of pain intensity and improvement (AVAS) for each of the three patients (A–C) throughout the five intervention sessions (day 1–5). The dotted line represents the data trend. Significant differences between the pain improvement mean values of the anodal and sham stimulation conditions were found in patients 1 and 2, with superior improvements after anodal stimulation (p < 0.001 and p = 0.001, respectively). The differences between the mean values of the anodal and sham conditions in patient 3 were not significant, although there was a trend toward significance (p = 0.08).
