In which Nova Scotia Hearing and Speech Centres are these tests performed?

There are two locations that currently conduct VNG testing for the NSHSC – The QEII HSC-Dickson Building site and the Cape Breton Regional Hospital in Sydney. Rotary Chair, VEMP, and Posturography testing are conducted exclusively at the QEII HSC – Dickson Building site.

What instructions are important to know before testing?

For VNG and rotary chair, testing is not painful and does not leave ill effects afterwards although there may be temporary feelings of dizziness during parts of the tests. If nausea is common with your balance problem, avoid eating for two hours prior to your appointment. If your balance problem interferes with driving, it would be advisable for you to have a companion with you.

Please do not wear make-up on the day of testing as this can affect test results. For posturography testing, you should wear comfortable clothing, and you will be asked to remove your footwear.

How long does testing take?

Testing time is approximately 60 - 90 minutes for each vestibular test.

Are there medications which can affect test results?

Yes, to get accurate results there are a number of medications that should be discontinued 48 hours prior to testing. These include pain pills (with codeine), sleeping pills, cold or allergy pills, antihistamines, tranquilizers, anti-nausea pills, sedatives, alcohol and anti-dizziness pills.

Who can refer for these balance tests?

The specialists who can refer for these balance tests are Neurologists and Otolaryngologists (ENT).
