This study is looking at how vagal nerve stimulation (VNS) affects stomach functions like how quickly food leaves the stomach (gastric emptying) and how much the stomach can stretch to hold food (gastric accommodation). VNS involves a device that sends electrical impulses to the vagus nerve, which can help with conditions like epilepsy and depression, and also sends impulses to the stomach. Researchers want to see if VNS increases the stomach's ability to stretch and speeds up how fast food empties from it. They will compare results from 12 participants who already have a VNS device implanted for drug-resistant depression with information from healthy individuals. The study is currently unclear on its recruitment status and aims to enroll 16 participants.

Study design

This is a single-cohort study involving 12 participants who already have a Vagus Nerve Stimulant device implanted. Researchers will compare their results to data from healthy individuals.

What's involved

You would need to attend one visit, which is expected to take about 4.5 hours. During this visit, you would undergo a combined gastric emptying and accommodation test.

Compensation

Not stated in the trial record.
