Consistency of cutaneous changes in heat pain thresholds to deep electrical pain stimulation. Changes in cutaneous heat pain threshold (HPT, ΔC°) during vs before deep electrical pain stimulation in various tissues shown as scatter plots. The x-axis shows the changes on day 2 (=post–pre day 2) and the y-axis the changes on day 1 (=post–pre day 1). Spearman’s ρ and P-value shown for each scatter plot.
