Figure 6. — Correlations between psychophysical parameters and OA-related brain activation. (a) A significant correlation was observed between PD-Q and ΔBOLD of ACC in CP with a Pearson correlation coefficient of R = −0.660, p = 0.004. (b) A significant correlation was observed between BDI and ΔBOLD of putamen in HC with a Pearson correlation coefficient of R = 0.561, p = 0.019.

OA: offset analgesia; PD-Q: PainDETECT questionnaire; BOLD: blood oxygenation level-dependent; ACC: anterior cingulate cortex; BDI: Beck Depression Inventory; HC: healthy control; CP: patients with chronic pain.
