Vestibular testing is performed by audiologists, ENT doctors, neurologists, and vestibular physical therapists, though each plays a different role. Audiologists most often run the equipment-based diagnostic tests themselves, while physicians order and interpret results to guide treatment decisions. Understanding which provider does what can save you time and get you to the right specialist faster.
Audiologists Run Most Lab-Based Tests
Audiologists are the professionals most likely to be in the room with you during vestibular testing. They are trained to administer and interpret the full battery of balance-related lab tests, including videonystagmography (VNG), the video head impulse test, and vestibular evoked myogenic potentials. These tests measure involuntary eye movements, how your eyes respond when your head is turned quickly, and how your inner ear reacts to sound. A complete VNG session takes roughly 90 minutes.
Audiologists work within balance centers or ENT offices, often as the diagnostic arm of a larger team. At many academic medical centers, the audiology team works alongside ENT surgeons, neurologists, neurosurgeons, and rehabilitation specialists to piece together a diagnosis. The audiologist gathers the data; the referring physician uses it to determine the cause and plan treatment.
ENT Doctors and Neurotologists
An ear, nose, and throat doctor (otolaryngologist) is frequently the physician who orders vestibular testing and interprets the results in the context of your symptoms. ENTs handle common inner ear conditions like benign paroxysmal positional vertigo (BPPV) and Meniere’s disease. They also perform hands-on diagnostic maneuvers in the office. The Dix-Hallpike test, considered the gold standard for diagnosing the most common form of BPPV, involves moving your head into specific positions while the doctor watches for characteristic eye movements. A separate maneuver called the supine roll test diagnoses BPPV affecting a different ear canal.
For more complex cases, a neurotologist offers deeper expertise. Neurotologists are ENT doctors who complete an additional two years of fellowship training focused on inner ear disorders, balance problems, and skull base conditions. They handle situations like superior canal dehiscence syndrome, recurrent middle ear problems that haven’t responded to standard treatment, and tumors near the ear or brainstem. If your dizziness has been difficult to diagnose or keeps coming back, a neurotologist is often the next step.
Neurologists Handle Brain-Related Causes
Not all dizziness starts in the inner ear. Vestibular migraine, for example, sits at the intersection of neurology and ear medicine, and a neurologist is often the lead provider for diagnosis and treatment. Neurologists are also critical when there’s concern about a stroke or other vascular problem causing vertigo. Cerebrovascular disorders account for roughly 3 to 7 percent of cases where someone presents with vertigo, and the vertigo typically involves blood supply problems in the back of the brain. In older patients with cardiovascular risk factors and sudden-onset vertigo, brain MRI becomes an essential part of the workup.
The key distinction: if your dizziness comes with neurological symptoms like slurred speech, numbness, confusion, or memory problems, a neurologist is the right specialist. Isolated vertigo can occasionally be the only sign of a stroke when a specific artery supplying the inner ear is involved, which is one reason providers take new vertigo seriously even when it seems straightforward.
Vestibular Physical Therapists
Physical therapists who specialize in vestibular rehabilitation perform their own set of balance assessments, though these are functional rather than equipment-based. Their testing focuses on how well you move and balance in real-world conditions. A typical initial evaluation includes gait analysis, standardized balance confidence questionnaires, and a series of standing tests designed to isolate your vestibular system from your other balance inputs.
One common test, the modified clinical test of sensory interaction and balance, has you stand in four progressively harder conditions: eyes open on a firm surface, eyes closed on a firm surface, eyes open on a foam pad, and eyes closed on a foam pad. That final condition challenges the vestibular system most directly because it removes both visual cues and reliable feedback from your feet. Another test, the sharpened Romberg, asks you to stand with your feet in a heel-to-toe position, eyes closed, arms crossed. If you can’t hold steady for 30 seconds, it points toward a vestibular problem.
These therapists don’t typically diagnose the underlying condition, but their assessments guide the rehabilitation plan once a diagnosis is in place.
How Referrals Typically Work
Most people start with their primary care doctor, who evaluates the dizziness and decides whether to refer to a specialist. Insurance often requires a written order from the treating physician before vestibular testing is covered. Medicare specifically requires that the ordering physician is either providing a consultation or actively managing the medical problem that prompted the testing. Many insurance plans follow similar rules.
Your primary care doctor may refer you directly to an audiologist for testing, to an ENT for evaluation, or to a neurologist if the symptoms suggest a brain-based cause. In practice, you might see more than one of these providers. A common path is: primary care to ENT, ENT orders vestibular testing performed by an audiologist, and then results come back to the ENT for a treatment plan. If rehabilitation is needed, a vestibular physical therapist enters the picture after that.
How to Prepare for Testing
Several common medications can dampen your vestibular system enough to skew test results. If you’re scheduled for vestibular testing, your provider will likely ask you to temporarily stop taking antihistamines like meclizine, diphenhydramine, and dimenhydrinate. Anti-anxiety medications in the benzodiazepine class also suppress vestibular responses and usually need to be paused. The broader list of substances that can affect results includes antiemetics (anti-nausea drugs), sleeping pills, sedatives, opioids, antidepressants, alcohol, marijuana, caffeine, and tobacco.
Your testing center will give you specific instructions about which medications to stop and how far in advance. Don’t stop any prescription medication without checking with the doctor who prescribed it first, since some of these drugs carry risks if discontinued abruptly.
