Videonystagmography (VNG) is a test utilised at Brain + Body Health as part of a comprehensive evaluation of the vestibular system in the inner ear which is responsible for balance. The VNG test requires video goggles to measure a specific involuntary eye movement called nystagmus where the eyes move side to side, up and down or both. Nystagmus may be rapid or slow, steady or jerky and these characteristics provide us with valuable information to help determine the cause of a balance or inner ear condition.
We can also use the NG to measure the speed of your eye movements which tells us about what areas in your brain are working well and what areas are sub-optimal.
