Q1. What are the most common vertigo and balance tests?
The core diagnostic battery includes VNG (Videonystagmography), VEMP (Vestibular Evoked Myogenic Potentials), and ECochG. Think of these as a specialized toolkit: VNG uses high-tech goggles to track eye movements; VEMP checks the specific nerves responsible for balance; and ECochG measures the fluid pressure inside your inner ear. Together, they provide a 360-degree view of why you feel unsteady.
Q2. Is the VNG test painful?
Not at all. The VNG is entirely non-invasive and does not involve any needles. You simply wear a pair of comfortable, infrared goggles and follow moving lights or change your sitting position. While you might feel a brief moment of “spinning” during certain parts of the test, it is a controlled environment designed to identify the source of your dizziness without discomfort.
Q3. How long do these vertigo and balance tests take?
A comprehensive evaluation usually takes between 60 to 90 minutes. This timeframe allows the audiologist to conduct multiple tests—like the VNG, VEMP, and ECochG—without rushing. It’s important to have this dedicated window so the equipment can capture precise data, ensuring your final “balance profile” is as accurate as possible.
Q4. Do I need to stop my medications before the test?
Yes, typically. Most anti-dizziness, sedative, or anti-anxiety medications must be stopped 48 hours prior to your appointment. These drugs can “mask” your symptoms, making it harder for the equipment to detect the underlying issue. Always consult with your doctor before pausing any prescribed medication.
Q5. Can I drive myself home after the appointment?
We strongly recommend having a family member or friend accompany you. Because these tests are designed to stimulate your balance system, you may feel temporary lightheadedness or mild “sea-sickness” afterward. Having a ride ensures you get home safely while your equilibrium settles.
Q6. What is the actual difference between vertigo and dizziness?
While people often use them interchangeably, they are different sensations. Vertigo is the specific feeling that you or the room is spinning or tilting. Dizziness is a broader term for feeling lightheaded, “spaced out,” or generally unsteady on your feet. Knowing which one you feel helps the audiologist choose the right tests.
Q7. Why do I specifically need an ECochG?
An ECochG is the definitive choice for confirming Ménière’s disease. It measures the electrical “stress” caused by excess fluid pressure in the inner ear. If you have “roaring” tinnitus or a constant feeling of “fullness” in your ear along with dizziness, this test provides the “pressure reading” needed for a diagnosis.
Q8. Will these tests tell me if I have BPPV?
Yes. The VNG test is excellent for diagnosing Benign Paroxysmal Positional Vertigo (BPPV). By moving your head into specific positions while wearing the goggles, the audiologist can see if tiny “ear crystals” have displaced into the wrong part of your inner ear, which is a very common (and treatable) cause of spinning.
Q9. What should I wear for my appointment?
Wear comfortable, loose-fitting clothing as you will be asked to lie down and move into different positions. Crucially, do not wear eye makeup (mascara, eyeliner, or heavy shadow). The VNG goggles use sensitive cameras to track your pupils, and makeup can confuse the sensors.
Q10. What happens once the tests are finished?
Your audiologist will compile the data into a detailed report. These results are then shared with your ENT specialist or physician to create a personalized rehabilitation plan. This might include medication, specialized exercises (Vestibular Rehab), or lifestyle changes to manage ear pressure.
