Overview
Brief Summary
This is a research study to find out if mental health symptoms in patients admitted to the Institute of Psychiatry are affected by a form of ear stimulation called transcutaneous auricular vagus nerve stimulation, or taVNS. Participants will receive ear stimulation during their inpatient treatment at the Institute of Psychiatry. Participants will be randomly assigned to either receive ear stimulation for 1 day (up to 9 treatments over the course of a single day) or 3 days (up to 3 treatments per day), and will have a 50:50 chance of being in either group (like the flip of a coin). Each treatment will last up to 30 minutes and there will be a break of at least 30 minutes in between treatments. The study team will ask participants to complete a group of questionnaires at the beginning and end of the study. In addition, there are several questionnaires that will be completed daily while participants are receiving ear stimulation. Participants in the 1 day stimulation group will also receive 2 days of follow up questionnaires after the initial day of stimulation. The questionnaires will ask questions about mental health symptoms that subjects may or may not be experiencing, including questions about mood, anxiety, and sleep. The ear stimulation treatments will not interfere with the care subjects are receiving from the medical team. In order to qualify for this study, participants must be actively receiving inpatient care at the MUSC Institute of Psychiatry.
