The causes of dizziness, vertigo, and disequilibrium can be hard to identify but are typically connected to a peripheral vestibular disorder (related to the inner ear) or central vestibular disorder (related to processing issues in the central nervous system). > Overcoming the accidents and additional problems related to disequilibrium > requires accurate diagnosis and targeted treatment, which is why Pacific > Hearing, Inc. has incorporated Vestibular Evoked Myogenic Potential (VEMP) > testing into our diagnostic services. How does VEMP testing work and what should you expect to take place during testing? UNDERSTANDING VESTIBULAR DYSFUNCTION, SYMPTOMS, AND CAUSES For a more complete understanding of VEMP testing, it is necessary to have a better understanding of vestibular dysfunction, which is a disturbance in the body’s balance system due to either peripheral or central causes. Sensory input from your vision, touch sensors in the feet, trunk, and spine, and the vestibular system in your inner ear work together to provide positional signals to the central vestibular system, which processes those signals and communicates to other parts of the body to make adjustments that help you remain steady on your feet. Although symptoms such as dizziness, vertigo, nausea, vomiting, intolerance to head motion, nystagmus, unsteady gait, and postural instability can come from non-vestibular dysfunction causes, they are quite common to vestibular dysfunction. The symptoms of vestibular dysfunction can be caused by many conditions, but among the most common are acoustic neuroma, benign paroxysmal positional vertigo (BPPV), labyrinthitis and vestibular neuritis, Mal de débarquement syndrome, Ménière’s disease, and otitis media, which is common in children. What Is VEMP Testing? The vestibular evoked myogenic potential reflex is produced by the inferior vestibular nerve, which provides evidence of the integrity of the vestibular response. It is this reflex that VEMP testing measures. VEMP testing is a relatively new means of vestibular evaluation, receiving FDA approval in 2015. Although the diagnostic utility and the scientific evidence supporting the use of VEMP testing is still being investigated, two primary VEMP responses receive the most attention. Cervical VEMP, also known as a cVEMP, and ocular VEMP, or oVEMP, are responses that measure otolith function (linear sensors of the inner ear). Assessing the saccular function and inferior branch of the vestibular nerve involves the use of cVEMP testing, while assessing the utricular function and the superior branch of the vestibular nerve are done using oVEMP. WHAT HAPPENS DURING A VEMP TEST? Vestibular Evoked Myogenic Potential (VEMP) testing is in conjunction with the VNG evaluation for patients experiencing dizziness or balance problems. During the VEMP test, you will recline at an angle with sticker electrodes attached to your head and neck. As you lift your head slightly, you will hear a knocking sound, which is measured by the electrodes. By lowering the knocking to see if one ear is more sensitive than the other or by testing only one ear at a time, we are able to localize the side that may be involved in causing the dizziness or imbalance. WHAT DOES THE VEMP TEST DIAGNOSE? Although it’s not the sole tool for diagnosis in most conditions related to dizziness, vertigo, and balance disorders, VEMP testing is typically used to aid in conjunction with VNG testing in the evaluation of conditions like vestibular neuritis (inflammation of the vestibular nerve) and Meniere’s disease (fluid abnormality of the ear). Patients affected by vestibular migraines show an absent or reduced VEMP amplitude in one or both ears, motivating additional investigation into the relationship between VEMPs. This form of testing has also been used for the early identification of demyelinating disorders, such as multiple sclerosis, leading to treatments designed to prevent the rapid decline and development of disabilities. VEMP testing can also aid in the diagnosis of superior semicircular canal dehiscence (SSCD), caused by a leakage of pressure and/or fluid from the inner ear structures. It is another condition that produces symptoms of vestibular dysfunction as well as difficulty focusing the eyes, hearing loss, and sound sensitivity issues. The primary purpose of VEMP testing used by your audiologist is to determine if the saccule and the vestibular nerve are intact and functioning properly. When functioning at their best, the saccule and the inferior vestibular nerves work together to send signals to the muscles of the eyes in response to head movements.
