ID: 222839 Laryngeal Motor Evoked Potentials: Clinical Asset in Vagus Nerve Stimulation Using a Synchronized Programmable Implant

Abstract

Vagus nerve stimulation (VNS) consists in delivering consecutive electrical pulses to the brain via the left vagus nerve, using a neurostimulator. The stimulation of the vagus nerve triggers laryngeal motor evoked potentials (LMEPs) through the activation of the recurrent laryngeal nerve. This study describes a set of devices that allow for recording the LMEP biomarker in a non-invasive, efficient, and easy-to-use manner. The analysis of such recordings provides several relevant clinical applications for patient follow-up and therapy personalization.
