Statistics for cold pain sensitivity.

	Stimulation Side	tDCS Type	Stimulation Side × tDCS Type
Cold pain threshold	F1, 24 = 7.65*, ${\mathrm{\eta }}_p^2=0.242$	F2,48 = 3.83*, ${\mathrm{\eta }}_p^2=0.138$	F2,48 = 0.08, ${\mathrm{\eta }}_p^2=0.003$
Cold pain tolerance	F1, 24 = 1.52, ${\mathrm{\eta }}_p^2=0.059$	F2,48 = 0.19, ${\mathrm{\eta }}_p^2=0.008$	F2,48 = 2.13, ${\mathrm{\eta }}_p^2=0.082$
Pain intensity	F1, 24 = 0.13, ${\mathrm{\eta }}_p^2=0.005$	F2,48 = 1.37, ${\mathrm{\eta }}_p^2=0.054$	F2,48 = 0.38, ${\mathrm{\eta }}_p^2=0.016$
Unpleasantness	F1, 24 = 0.01, ${\mathrm{\eta }}_p^2<0.001$	F2,48 = 0.42, ${\mathrm{\eta }}_p^2=0.017$	F2,48 = 1.59, ${\mathrm{\eta }}_p^2=0.062$

Statistics were obtained by applying a two-way repeated measures ANOVA, with two within-participant factors of Stimulation Side (the hands contralateral and ipsilateral to the HD-tDCS side) and tDCS Type (anodal, cathodal, and sham HD-tDCS). *p < 0.05.
