VNG Testing: The Revolutionary Approach to Diagnosing and Treating Traumatic Brain Injuries
Traumatic brain injuries can have a lasting impact on a person’s overall health and well-being. One of the symptoms that can arise after a traumatic brain injury is balance issues, which can lead to a wide range of problems. One way that healthcare professionals diagnose and evaluate balance issues is through VNG (videonystagmography) testing. If you’ve never heard of VNG testing before, don’t worry – this post will provide you with all the information you need to understand what it is, how it works, and who might benefit from it.
Understanding the Importance of VNG Testing
After a Traumatic Brain Injury
1
What Is VNG Testing?
It is a diagnostic test that measures a patient's eye movements and evaluates the balance system's effectiveness. This test uses video technology to record and analyze a patient's eye movements while they complete a series of movements to test balance, such as moving their head in different directions or following a moving target with their eyes. This non-invasive and painless test makes it an ideal option for many patients.
2
How Does VNG Testing Work?
During a testing session, a healthcare professional will use infrared video cameras or goggles to track a patient's eye movements. A series of tests are performed that assess the function of the inner ear, eye movements, and nervous system. A patient wears goggles or infrared cameras to track eye movement. Different tests are used to evaluate different parts of the balance system, such as the vestibular system, which contributes to balance and stability.
3
What Are The Types Of VNG Testing?
There are different types of VNG tests that healthcare professionals may use to diagnose and evaluate balance issues. The most common types of tests include:
• Caloric testing – uses hot and cold air or water to stimulate the inner ear and measure the response.
• Dynamic positioning – involves the patient lying down, sitting up, or moving into different positions while their eye movements are tracked.
• Optokinetic testing – involves a moving target that the patient follows with their eyes to measure eye movements and visual tracking.
• Head impulse testing – involves quick, sudden head movements to measure the vestibulo-ocular reflex (VOR), which contributes to balance and stabilization of vision.
• Posturography – involves standing on a platform and tracking the pressure changes to determine balance.

What to Expect From a VNG Testing Session?
Testing sessions typically last between 60-90 minutes. Patients are advised to wear comfortable clothing and avoid caffeine or other stimulants before the test. Patients will perform different movements during the test while wearing infrared cameras or goggles. It's important to follow the healthcare professional's instructions and remain still during the test to ensure accurate results.
5
Who Might Benefit From VNG Testing?
Patients who experience balance issues or dizziness after a traumatic brain injury may benefit from VNG testing. This test can help healthcare professionals diagnose the cause of the balance issues and develop an effective treatment plan. VNG testing is also used to evaluate patients with vertigo, migraines, and other conditions that affect the balance system.
6
Risks of VNG Testing
The testing is generally considered safe and non-invasive, but there are some risks associated with the test. Some patients may experience dizziness or nausea during the test due to the movements involved. If this occurs, the test may need to be rescheduled. Patients should also inform their healthcare professional if they are pregnant, have a pacemaker, or have other medical conditions that may make VNG testing unsafe.
7
What Are The Side Effects Of VNG Testing?
Most patients do not experience any side effects from the testing. In some cases, patients may feel dizzy or disoriented during or after the test. This is usually temporary and will resolve with time. It's important to inform your healthcare professional if you experience any unusual symptoms.
8
Who Shouldn't Use VNG Testing?
Videonystagmography testing is not recommended for patients who are pregnant or have certain medical conditions that may make the test unsafe. Patients with pacemakers or other implanted devices should also avoid VNG testing, as it may interfere with the device's function. Your healthcare professional will evaluate your medical history and determine if VNG testing is safe for you.
9
What Are Other Testing Options for balance issues?
VNG testing is just one of several diagnostic tests that healthcare professionals may use to evaluate balance issues. Other tests include electrooculography (EOG), electronystagmography (ENG), and posturography. Your healthcare professional will evaluate your needs and recommend the most appropriate test.
You may benefit from a diagnostic test called videonystagmography (VNG). VNG is a non-invasive assessment healthcare professionals use to identify the root cause of balance disorders and determine the most effective treatment.
