VNG – Videonystagmogram

What is a Videonystagmogram (VNG)?

  • A Videonsytagmogram, or VNG, is a diagnostic test used to evaluate any balance difficulties or dizziness you may have.

How is it performed?

  • The test is performed in the office, by a registered Audiologist.
  • You will be wearing “goggles” during test, which will allow us to measure your eye and inner-ear activity during the test.
  • The test takes approximately 1 hour.
  • During the test, we will induce your dizziness. Your eye and inner-ear activity will be measured while you are dizzy.

What type of results will be obtained from the study?

  • The test will tell us whether your dizziness is caused by an inner ear malfunction, or some problem inside your brain.
  • This test is especially useful in MS patients, as we are looking for some MS-induced CNS dysfunction which may not be clinically evident.
