Transcranial Direct Current Stimulation and the Interaction Between Chronic Pain and the Intestinal Epithelial Barrier in Patients With Chronic Inflammatory Bowel Diseases (IBD)
Transkranielle Gleichstromstimulation Und Die Interaktion Zwischen Chronischem Schmerz Und Der Intestinalen Epithelbarriere
In the study the investigators aim to test whether transcranial direct current stimulation (tDCS) induced pain reduction is in association with functional changes in the brain measured with magnetic resonance imaging (MRI) and also with a change in permeability of the intestinal epithelial barrier in patients with chronic inflammatory bowel diseases (IBD)
Hypothesis: Transcranial direct current stimulation can reduce the perception of pain in patients with chronic inflammatory bowel diseases, which is in association with changes in the brain measured via MRI. Additionally, transcranial direct current stimulation and the induced pain reduction influence the permeability of the intestinal epithelial barrier
