Effect Of Percutaneous Electrical Nerve Field Stimulation on Symptom Control/Nervous System Activity in Patients w/Diabetes Types 1/2

Starting soon · Not applicable · Has a placebo group

Conditions studied: Diabetes, Gastroparesis

In brief

The purpose of this study is to find out if we can stimulate the vagus nerve. The vagus nerve is a largely internal nerve that controls many bodily functions, including stomach function. We hope that electrically stimulating the nerve around the external ear will also stimulate the internal vagus nerve. If it does, then we hope that this will help our treatment of patients with nausea and vomiting and disordered stomach function.
