NCT06700200

Brief Summary

To study the impact of tVNS on gut motor function, with regards to its potential to induce phase III contractions in the upper GI tract, in healthy subjects. Hypothesis: We hypothesize that tVNS will induce on average an excess of 1 additional phase III contraction of antral origin in the fasted period compared to sham stimulation.

Outcome Measures

Primary Outcomes (1)

  • Phase III Antral contractions

    A clinically meaningful increase in the number of phase III contractions of antral origin in the fasted period during the tVNS stimulation compared to the sham stimulation.

    During ADM

Secondary Outcomes (2)

  • Motilin and pancreatic polypeptide levels

    During ADM

  • Other ADM parameters

    During ADM

Study Arms (2)

taVNS

ACTIVE COMPARATOR

The vagus nerve will be stimulated transcutaneously. The concha of the left ear will be stimulated.

Device: taVNS

Sham stimulation

PLACEBO COMPARATOR

The vagus nerve will be stimulated transcutaneously. The concha of the left ear will be stimulated. The device is inactive.

Device: taVNS
