What is the JVA? The JVA or Joint Vibration Analysis machine is a small set of headphones which we place in front of the patient’s ears. But instead of the patient listening to music, this small sensor will pick up vibrations inside the patient’s jaw joint. Healthy jaw joints make very little friction as you open and close and they really don’t have very much vibration, whereas a damaged joint depending on the kind of damage will make a very different type of vibration that is picked up. Based on the type of damage we see we can determine whether any other imaging like an MRI or CT scan is necessary to come to a thorough diagnosis.
