VNG Testing
ESP Sports Medicine is an official Medtrak Diagnostics Testing Center for concussions and traumatic brain injury (TBI) related to motor vehicle accidents and personal injury cases.
What does a VNG Test include?
VNG tests done through Medtrak include three tests that objectively diagnose the existence of a head injury. This ‘battery of tests’ allows for diagnosis and guidance of vestibular and cognitive therapies for concussion and head injury patients. The tests used are:
Vestibular Testing
Vestibular testing runs the patient through a series of eye movements. While the patient is doing these eye movements a camera records the patient’s eye and measures any nystagmus present. Nystagmus is a condition in which the eyes make repetitive, uncontrolled movements and is an objective sign of head injury. The eye movements form a graph. A neurologist then reads this graph and determines where the brain injury is present.
Balance/Coordination Testing
Patients step onto a balance board for the balance and coordination test. This board measures the patient’s center of gravity. The patient then participates in a few tests that challenge their balance and coordination. A neurologist then evaluates these tests by comparing them to normal tests. The neurologist then determines if the patient is at a deficit because of their head injury.
Neurocognitive Testing
Neurocognitive testing uses a tablet that runs the patient through a 20-minute test. This test is a lot like brain games you might play on your own. It can determine if a patient has cognitive issues related to their car accident head injury.
These three tests combined allows clinicians to provide an objective diagnosis of the cause of some of the post-traumatic symptoms. These symptoms may include dizziness, vertigo, fatigue, problems with balance, balance/coordination, blurred vision, memory problems, anxiety, depression, and personality changes.
