Due to the increase in pain intensity ratings during exposure to the C-HP model the time factor was highly significant ( t -stat = 9.5; p < 0.0001).

Furthermore, these subjects experienced a greater reduction in mean area of secondary hyperalgesia after anodal tDCS (19 cm 2 ) compared to cathodal (9 cm 2 ) or sham (4 cm 2 ) stimulation, although this difference did not reach statistical significance (anodal versus sham t -stat = -1.8, p = 0.08; anodal versus cathodal t -stat = -1.5, p = 0.15).
