balance assessment: what to expect
Balance assessments are conducted using videonystagmography (VNG), which allows us to evaluate your balance function by monitoring your eye movement with specialised goggles.
After a detailed discussion about your balance symptoms, we perform a series of diagnostic tests looking for any induced dizziness or unusual eye movements under differing conditions of eye, neck, body, and head position.
Following this, it is necessary to induce a mild dizziness by altering the temperature of your ear canals using warm or cool air while you are lying safely on a bed. Some patients are nervous about the dizziness that can occur during this test but it is normally brief and bearable.
Prior to your appointment:
Please ask your GP to check your ear canals for excessive wax.
Please do not take any dizziness medication for 48 hours.
Please thoroughly remove all eye makeup.
Please do not consume alcohol for 24 hours.
