Brief Summary

This randomized control trial aims to evaluate the effect of transcutaneous auricular vagal nerve stimulation in patients with irritable bowel syndrome. The intervention will be 8 weeks of treatment with a vagal nerve stimulator. The main objectives are:

  • To evaluate the clinical response, defined as a decrease of at least 50 points on the IBS-SSS questionnaire, of the treatment.
  • To ascertain whether the autonomic-vagal neurosignature, derived from pre-treatment registration of symptom profiles, autonomic responses and imaging of neuronal activity as a reaction to stress is able to predict therapeutic response to tVNS accurately.
  • To evaluate the effect of treatment on quality of life
  • To evaluate the effect of treatment on depression
  • To evaluate the effect of treatment on anxiety Participants will be asked to wear a wearable (Fitbit) and fill out a daily questionnaire for one week. Thereafter, a functional brain MRI will be performed. In the intervention group patients will receive transcutaneous nerve stimulation for 8-weeks at home. The comparison group will receive the same device but with a non-conducting electrode. Patients fill out weekly questionnaires during the treatment period and at follow-up moments 3 and 6 months after finishing the treatment period.
