- VNG testing is a series of tests designed to document a person’s ability to follow visual objects with their eyes and how well the eyes respond to information from the vestibular system. This test also addresses the functionality of each ear and if a vestibular deficit may be the cause of a dizziness or balance problem.

VNG Testing - Videonystagmography VNG Testing - Videonystagmography. The Videonystagmography (VNG) is a test of your balance system. The test records nystagmus (quick eye jerks) by a camera. There are neural connections that stretch from the balance mechanism in the inner ear to the muscles of the eye. A disorder of the balance mechanism results in small eye jerks that can only be detected by a sophisticated computer.

Frequently Asked Questions About LNG What is LNG? Liquefied natural gas, or LNG, is natural gas in its liquid form. When natural gas is cooled to minus 259 degrees Fahrenheit (-161 degrees Celsius), it becomes a clear, colorless, odorless liquid. LNG is neither corrosive nor toxic. Natural gas is primarily methane, with low concentrations of other hydrocarbons, water, carbon dioxide, nitrogen, oxygen and some sulfur compounds.

Children's (Pediatric) Voiding Cystourethrogram A children's (pediatric) voiding cystourethrogram (VCUG) is an x-ray examination of a child's bladder and urinary tract that uses a special form of x-ray called fluoroscopy and a contrast material. An x-ray (radiograph) is a noninvasive medical test that helps physicians diagnose and treat medical conditions.

Glaucoma Visual field testing actually maps the visual fields to detect any early (or late) signs of glaucomatous damage to the optic nerve. In order to find and follow glaucoma, visual fields are measured by a computer one eye at a time. One eye is covered and the patient places his or her chin in a type of bowl.

What is a Megger Test? The Megger test is a method of testing making use of an insulation. Insulation Tester. resistance meter that will help to verify the condition of electrical insulation. This is certainly not a new test, and has been in use for a number of years. One of the reasons that it is still such a popular option is because it is nondestructive. The test does have a limit of between 500 and 1000 volts, so it may not always be able to detect some insulation punctures.

Electrocochleography (ECOG) Electrocochleography (ECOG) Electrocochleography (ECOG) is a diagnostic test that examines the function of the inner ear. This test measures the electrical potentials generated in the inner ear in response to sound. The ECOG is most often used to determine if the inner ear has an excessive amount of fluid pressure, which can cause symptoms such as hearing loss, aural fullness, dizziness, and/or tinnitus. These symptoms are sometimes indicative of certain ear pathologies such as Meniere’s disease or endolymphatic hydrops.

EMG/NCV (Electromyography/Nerve Conduction Velocity) EMG (electromyography) is a test used to measure the electrical activity of a patient's muscles. NCV (nerve conduction velocity), on the other hand, measures the intensity and the speed of the electrical signals that travel along the nerves, in addition to the reaction time for a response to these signals.
