Summary

The goal of this clinical trial is to learn if stimulating the vagus nerve in combination with a motor task in people with multiple sclerosis can improve motor function. The main questions it aims to answer are:

* Is stimulating the vagus nerve safe and feasible after demyelinating episodes?
* Does a paired motor task with vagus nerve stimulation improve motor function with someone who has multiple sclerosis?

Researchers will compare active vagus nerve stimulation to a sham stimulation to see if the paired vagus nerve stimulation can improve motor control.

Participants will:

* Come in for study visits over a six month period. Study visits are three times weekly for the first month, then single follow up visits at two, three, and six months.
* During study visits, participants will complete 30 minutes of the paired vagus nerve stimulation with a motor task, specifically the grooved peg test.
* At various timepoints throughout the study, motor, disability, and neurophysiological assessments will be administered, including the Timed 25-Foot Walk Test, Expanded Disability Status Scale (EDSS), Upper Extremity portion of the Fugl-Meyer Assessment, Dellon-Modified Moberg Pick-Up Test, Multiple Sclerosis Impact Scale-29 (MSIS-29), motor evoked potentials (MEPs), and visual evoked potentials (VEPs). MRI assessments will also be performed to evaluate exploratory imaging metrics of potential remyelinative efficacy.

Conditions

Interventions

DEVICE

Closed Loop Trans-Auricular Vagus Nerve Stimulation System

A closed loop system that delivers stimulation to the vagus nerve via the ear non-invasively following a trigger event.

DEVICE

Placebo

A closed-loop vagus nerve stimulation device that can deliver sham stimulation to the ear to simulate stimulation of the vagus nerve.
