Fig 2 Patients’ reports of pain during deep electrical pain stimulation (green areas) and stimulation location (blue mark). Number of patients with pain at a specific area on day 1 and/or 2 with the number of patients having pain at the same location on both days in parentheses.

Fig 3 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.
