Brief summary (from the registry)
The effect of transauricular electrical vagal nerve stimulation (taVNS) will be studied on temporal summation of heat pain (TSP) in 30 patients with chronic low-back pain and in 30 heathy volunteers. Participants will receive either taVNS or sham stimulation before and during TSP induction in a randomized crossover manner. The participants will be unaware regarding the type of intervention.
