Abstract:
Persistent abdominal pain (PAP) is linked to reduced prefrontal alpha oscillations, correlating with pain severity. Our study found that 30 Hz transcutaneous auricular vagus nerve stimulation (taVNS) effectively enhanced these alpha rhythms in key prefrontal regions and was selected for intervention. A 20-day 30 Hz taVNS treatment significantly alleviated pain and promoted the normalization of brain activity, demonstrating its potential as a non-pharmacological therapy for PAP.
