Fig. 8From: Quantitative sensory phenotyping in chronic neuropathic pain patients treated with unilateral L4-dorsal root ganglion stimulationSomatosensory profile of the CRPS-affected knee before (open circles) and after L4-DRG stimulation (black circles) normalized to QST from the contralateral control knee (a) and mechanical or thermal dysesthesias (DMA, PHS) (b). Sensitivity reduced after L4-DRG stimulation for cold pain threshold (CPT), pressure pain threshold (PPT) and pain summation (WUR). Sensitivity increased after L4-DRG stimulation for warmth detection threshold (WDT), mechanical pain threshold (MPT) and mechanical pain threshold (MPS). **p < 0.01, *p < 0.05, (*)p < 0.10 vs. contralateral control knee; #p < 0.05, (#)p < 0.10 pre vs. post L4-DRG stimulationBack to article page
