The symptoms being reported by the patient can be very useful as a first filter to narrow etiologic possibilities and serve as a framework for interpretation of the findings from the formal laboratory or by means of direct office examinations. Vestibular evoked myogenic potentials. Vestibular Disorders Section Overview.
