IHS Training Session: Acquiring VEMP Responses using SmartEP

This SmartEP training session covers the theory being the acquisition of Vestibular Evoked Myogenic Potentials, including cervical (cVEMP) and ocular (oVEMP). Material covers the use of different stimulators, electrode placement, settings, peak marking, comparison, and analysis.
