Temporal summation of second pain (TSSP), is thought to reflect central sensitization, a process linked to pain chronification. Lately, one study has shown how "affective touch" ('AT') is able to lower the pain sensation during TSSP, but the neural underpinnings of such interaction are still unknown. In the present EEG study, participants went through three conditions where a TSSP protocol was applied in concomitance with discriminative touch ('DT'), 'AT' or no tactile stimulation ('NoT'). Heat stimuli were delivered via a thermode attached to the dorsal side of the right wrist, while tactile stimuli on the lower right arm were delivered via an ad-hoc device. A fourth no-pain no-touch condition acted as a baseline. Measures of attention and (touch) pleasantness were also collected. Our results show that AT brought about a decrease of our participants’ pain as opposed to both DT and 'NoT', while DT did not produce any significant pain reduction. While there were no differences in terms of attention, as expected, AT was perceived more pleasant than DT. The analysis of the ERSP indicated that only AT (and not DT) differed from NoT, with a suppression of delta-theta, and beta frequencies at Cz. At Pz, a significant suppression of delta-theta, low alpha, beta and high gamma frequencies were found for AT compared to NoT. Also, at this electrode, a suppression of beta was recorded during AT compared to DT.The neural mechanisms linked to how AT interacts with pain could lead to new treatments to tackle central sensitization.
