If you ever wondered “what do my ears have to do with my balance?”- you’re not alone! The ears are an integral part of our balance system. Our inner ears sense how we are moving in space, and this signal is relayed to our eyes. We have three systems that help us to maintain our balance including the:
- Visual system (eyes)
- Vestibular system (ears)
- Somatosensory system (body)
Each system works together by consistently sending signals to the brain to assist with balance. When one or more of these systems are not working properly, our balance can be compromised.
When you or a loved one are referred for a full balance test and vestibular evaluation, you’ll encounter a few machines that may look intimidating. One of them being the posturographer. Not to worry- it really is not as intimidating as it looks!
Posturography is the study of balance which provides us with a wealth of information regarding how each system contributes to your overall balance health. During posturography, sensors in the platform will record miniscule movements. Your audiologist will inform you of all testing conditions prior to starting each test to ensure you are ready and comfortable with the instructions. Throughout the evaluation, your eyes may be open or closed, your visual field may move, and the floor may move at times as well; however, safety is our main priority. You will be wearing a harness that is going to be attached to a safety bar. Your audiologist will also be ready to steady you and stop the equipment whenever necessary.
Posturography is a wonderful tool that we are lucky to have. We obtain significant information regarding how your visual, vestibular, and somatosensory systems are working together to maintain your balance in different situations. The ears are responsible for a great portion of balance, and if not functioning properly, posturography can provide us with detailed information for treatment.
