Videonystagmography (VNG) & VEMP Testing



We combine the most powerful clinical vestibular assessment tools.


Videonystagmography (VNG) is a technology for testing inner ear and central motor functions, a process known as vestibular assessment. VNG testing is used to determine if a vestibular (inner ear) disease may be causing a balance or dizziness problem. 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. VNG remains the most utilized and available vestibular function test, while as Vestibular Evoked Myogenic Potentials (VEMP), remains under-utilized vestibular function. At IncusEar, we perform both VNG and VEMP because the combination offers a powerful synergistic and comprehensive test battery and helps more on efficient and efficacious means of management for the chronic dizzy patient.

In order to achieve the best test results, you should carefully follow these instructions:

  1. Contact lenses should NOT be worn 3 days prior to testing or on the test day. Glasses should be worn during the 3 days and during the test.
  2. Wearing flat or low heeled shoes is recommended.
  3. Please wash your face thoroughly. (Mascara, make-up, creams, and lotions should NOT be used.)
  4. Avoid solid foods or milk for 2 to 4 hours before the test.
  5. Please do not have any coffee, tea, cola, or caffeine after midnight on the day of the test.
  6. You shouldn’t take aspirin or medication containing aspirin for two days before the test.
  7. You shouldn’t consume alcoholic beverages or liquid medication containing alcohol for two days before testing.
