They are used to determine\nwhether symptoms of dizziness are being caused by the balance system of the\ninner ear. <\/p>\n\n\n<h2 class=\"wp-block-heading\" id=\"diagnostic-tests-for-the-vestibular-system\">Diagnostic Tests for the Vestibular System<\/h2>\n\n\n<p>The vestibular system is complex and responsible for many of\nthe body\u2019s functions. In order to narrow down the exact cause of dizziness, it\nis necessary to administer a variety of tests. These measure eye movements,\nhead movements, hearing and more. <\/p>\n\n\n\n<p>Studies indicate vestibular testing is extremely thorough\nand accurate in identifying inner ear disorders. Vestibular testing is also\nhelpful in determining whether additional diagnostic testing, such as an MRI,\nis needed. A battery of tests is administered in most cases. The most common\nones include:<\/p>\n\n\n\n<ul><li><strong>Electronystagmography\n(ENG). <\/strong>This series of tests measures\neye movements via electrodes placed around the eyes. ENG tests usually consist\nof four parts: evaluation of rapid eye movements, tracking tests to measure eye\nmovements as they follow a visual target, positional test for measuring\ndizziness in response to different head positions and a caloric test that\nmeasures responses to warm and cold water circulating through a tube in the ear\ncanal. Most people reporting dizziness or vertigo will be given ENG tests\ninitially. <\/li><\/ul>\n\n\n\n<ul><li><strong>Videonystagmography\n(VNG).<\/strong> This is similar to ENG\ntesting, but an infrared video camera attached to a pair of goggles is used in\nplace of electrodes. The same four-part testing process is utilized. <\/li><\/ul>\n\n\n\n<ul><li><strong>Rotary\nChair Tests.<\/strong> The rotary chair test\nmeasures eye movements in response to corresponding head movements; it is used\nto determine whether symptoms are related to an inner ear disorder or a brain\ndisorder. Like the ENG and VNG tests, either electrodes or a goggle-mounted\nvideo camera is used to record eye movements. You are seated in a computerized\nchair that moves. This test provides more detailed information about the\nfunction of the balance system than an ENG or VNG test.<\/li><\/ul>\n\n\n\n<ul><li><strong>Computerized\nDynamic Posturography (CDP).<\/strong>\nCDP tests measure how well the visual, vestibular and sensory systems work\ntogether to maintain balance. With this test, you stand on a platform and\nfollow a visual target while platform movements record the degree to which your\nbody sways. It includes an Adaptation Test in which the platform moves up and\ndown and a Motor Control Test where the platform moves forward and backward.\nThese are used to measure reflexive responses to unexpected movement. CDP is\nfrequently used those undergoing vestibular rehabilitation. <\/li><\/ul>\n\n\n\n<ul><li><strong>Vestibular\nEvoked Myogenic Potential (VEMP).<\/strong>\nVEMP testing is used to determine whether the saccule (an inner ear organ) and\nvestibular nerves are functioning properly. Electrodes are attached to the neck\nand sounds are transmitted through a pair of headphones. The electrical\nresponse of the sternocleidomastoid muscle in the neck is recorded.<\/li><\/ul>\n\n\n\n<p>These tests may be combined with additional hearing or diagnostic tests depending on the results.&nbsp;<\/p>\n\n\n<p>Call <span class=\"company-name \">Oregon Ear, Nose &amp; Throat Center<\/span> at <a href=\"tel:+15417797331\" class=\"phone \"> <span class=\"phNum\">(541) 779-7331<\/span><\/a> for more information or to schedule an appointment.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Vestibular testing involves a series of tests that are administered when you are experiencing dizziness.
