Are you struggling with dizziness, vertigo, or unexplained balance issues?
Do you have problems tracking objects or difficulty reading?
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.
Understanding Videonystagmography (VNG): The Key to Diagnosing Balance Disorders
Videonystagmography (VNG) is a diagnostic procedure that assesses the performance of the vestibular system, the brain, and the inner ear, essential for maintaining balance and spatial orientation. Often used to distinguish between central and peripheral causes of dizzy spells and vertigo, VNG is the gold standard for detecting vestibular disorders.
How Does VNG Work?
A VNG test participant will put on specialized goggles with cameras to track their eye movements in the infrared spectrum. Due to the close relationship between the vestibular system and the eyes, eye movement analysis is a reliable technique to assess inner ear function.
The VNG test May consists of two to three main components:
A VNG test participant will put on specialized goggles with cameras to track their eye movements in the infrared spectrum. Due to the close relationship between the vestibular system and the eyes, eye movement analysis is a reliable technique to assess inner ear function.
- Oculomotor tests: Evaluate the patient’s eye movements as they track an object in the visual field, such as a dot on a screen. This aids in assessing the central nervous system’s functionality and capacity to regulate eye movements.
- Positional tests: The head and body of the patient will be moved into different positions to gauge how the vestibular system reacts to these movements. This can help find problems with the sensory organs in the inner ear or the nerves that link them to the brain.
Who Can Benefit from VNG Testing?
Individuals experiencing unexplained dizziness, vertigo, or balance issues may benefit from VNG testing. Some common vestibular disorders that can be diagnosed with VNG include:
- Concussion/TBI
- Benign paroxysmal positional vertigo (BPPV)
- Meniere’s disease
- Vestibular neuritis or labyrinthitis
- Vestibular migraine
Additionally, VNG test can aid in diagnosing central nervous system conditions like traumatic brain injury, multiple sclerosis, or cerebral ataxia that can manifest as vertigo or balance problems.
Videonystagmography (VNG) is an essential diagnostic tool for identifying the root cause of balance disorders and guiding effective treatment plans.
One of the benefits of VNG test diagnose is that it is non-invasive and relatively quick. The test can usually be completed within 30 to 60 minutes, and there is no need for sedation or anesthesia.
Additionally, VNG testing is highly sensitive and can detect even subtle abnormalities in the vestibular system, making it an essential tool for diagnosing and managing balance disorders.
