What is involved in vestibular testing?

vestibular testing includes various tools used to evaluate whether the internal ear disorder causes the patient's dizziness. Several evaluation techniques determines whether the reflex in the ear that regulates the vision during movement works properly. Some tests are measuring Nystagmus, the involuntary eye movement that occurs when there is a problem in the vestibular area of ​​the ear. Balance can also be evaluated during vestibular testing.

Inner ear contains five sensors that keep vision in balance when the head or body moves. If any of the five areas are not working properly, dizziness and dizziness may occur. Vestibular testing can analyze how three of these five sensors work.

One form of vestibular testing is the test of a rotary chair that is used to measure the function in both ears simultaneously. The motorized chair changes the patient while monitoring and observing the lights or stripes. Involuntary eye movements are studied to see if the inner ear can be present DYSfunction of ISORDER or brain. During this test, the patient may become less dizziness if his vertigo is related to the inner ear and points to the potential state of the brain.

In the electronagmography test, the electrodes are located near each eye to record the movement of the eye during the test parts. The test checks one ear at once and tests the patient's balance system in four ways. It also evaluates nystagmus, while the patient tries to monitor the moving object with his eyes. The test may also reveal whether the position of the person's head causes dizziness. The third part of this type of vestibular testing, called a caloric test, uses warm or cold water injected into the ear canal to measure the visual reaction. The fistula test that measures the movement of the eye to pressure is applied to the inner ear is more sensitive.

The balance

is also sometimes evaluated by a posturography. The patient is placed on a moving platform,To evaluate whether the symptoms have improved with treatment. However, this type of vestibular testing is not considered reliable and can register normally when there is a vestibular disease.

dizziness and involuntary eye movement can stem from vestibular disease in inner ear, head damage or reaction to drugs. Vestibular testing can be useful as a first step towards diagnosis because it is cheaper than the types of tests that analyze the function of the brain. If vestibular testing cannot determine the problem with the inner ear, the patient may continue with more expensive procedures such as magnetic resonance imaging to explore brain disorders.
