You are not dizzy. You are unsteady. Those are different words for a reason.

VESTIBULAR TESTING

Vestibular testing measures balance and inner-ear function. It separates the four causes of unsteadiness in someone with neck disease: cord compression, an inner-ear problem, cervicogenic dizziness, or neuropathy and medication effects. Here it is part of the neck workup, not a referral you chase separately.

When the complaint is balance rather than pain, the neck is one of at least four candidates. Guessing between them is unnecessary, because they can be measured.

Why this is part of a neck workup

Gait and balance trouble in someone with neck disease is a truly unclear finding. The stakes on getting it right are high. It can be:

• Cord compression — degenerative cervical myelopathy (spinal cord dysfunction). Gait change is one of its earliest signs, and the one most often blamed on age. This is a surgical question and a time-sensitive one.
• Vestibular — an inner ear or central vestibular (brain balance center) problem that has nothing to do with the neck. It is being blamed on the neck because the neck also hurts.
• Cervicogenic dizziness — disturbed proprioceptive input (the body’s position sense) from an irritable upper cervical spine. It is real and contested. It is a diagnosis of exclusion (reached after other causes are ruled out), not a first assumption.
• Peripheral neuropathy or a medication effect. Both are common, and both are easy to overlook in people with pain.

Those four need different things done about them, and one of them needs a surgeon quickly. That is the case for measuring rather than assuming.

What we actually do

Vestibular testing here is part of the workup rather than a referral you chase separately. It puts numbers on balance and vestibular function instead of relying on a bedside impression. And it produces a result that can be compared over time.

One detail is worth knowing because it links this page to the rest of the site. Cervical vestibular evoked myogenic potentials are recorded from the sternocleidomastoid muscle. The neck is not incidental to vestibular testing. It is part of the apparatus.

What do vestibular test results show?

The useful output is not a single label. It is a distinction between a peripheral vestibular problem, a central one, and a balance deficit with normal vestibular function. That last one is the pattern you see in myelopathy and in proprioceptive cervicogenic dizziness. It points attention back to the spinal cord and the neck.

Gait assessment tools for degenerative cervical myelopathy have been systematically reviewed. They exist because clinical impression alone detects the early cases poorly. A measured baseline is also what lets you tell, a year later, whether somebody is getting worse.

When is unsteadiness from the neck an emergency?

Vestibular testing does not replace an urgent neurological assessment. Progressive gait deterioration, clumsiness in both hands, or bowel and bladder change are cord signs. They go straight to the urgent pathway. Testing is for the unclear presentations, which are the majority, not for the ones that are already clear.

What tests are included in vestibular testing?

This is not one test. It is a battery, and each part answers a different question.

• Videonystagmography records eye movement to detect nystagmus. That is involuntary eye drift. It reveals an imbalance between the two vestibular systems. It is the workhorse for separating a peripheral problem from a central one.
• Vestibular evoked myogenic potentials test the otolith organs (the inner-ear gravity sensors) and the nerve pathways from them. The cervical version is recorded from the sternocleidomastoid. That is why neck muscle tone affects the result, and why the test belongs in a neck workup rather than beside it.
• Posturography and quantified balance testing measure how well you actually stand. Vision and surface information are removed one at a time. This is what separates a vestibular deficit from a proprioceptive one. And proprioceptive is the pattern seen in myelopathy.
• Bedside oculomotor testing (eye movement exams), done properly, still beats early imaging at telling central from peripheral causes of acute vertigo.

What happens after an abnormal vestibular test?

An abnormal peripheral result goes to vestibular rehabilitation. It has good evidence, and it is not something we provide. It is a referral, and a specific one.

An abnormal central pattern, or a balance deficit with normal vestibular function, points back at the spinal cord. That is the finding that matters most here. That is because it raises myelopathy in somebody who arrived with a neck complaint. And it moves quickly rather than joining a waiting list.

A normal result with a normal gait is also useful. It closes a question that was open. It means the dizziness needs explaining somewhere else entirely. Medication, blood pressure, or a primary headache disorder are among the more common answers.

Cervicogenic dizziness, held to a proper standard

Disturbed proprioceptive input from an irritable upper cervical spine can produce unsteadiness. It is a real entity. It is also the diagnosis most likely to be reached for when nothing else has been found.

Applied properly, it is a diagnosis of exclusion. Vestibular causes are tested and normal. There are no central signs and no cord signs. Cervical findings plausibly account for it. Applied loosely, it is a label that stops the workup. We use it the first way.

Why this is not a referral you should have to chase

The usual route for a neck patient with a balance complaint is a referral to somebody else and a wait. Then a report arrives after the decision has been made. Doing it inside the workup folds that into the same episode of care. That matters most for the one diagnosis on the list that gets worse while you wait.

What people ask about balance testing

Why would a pain clinic test my balance?

Because gait trouble in a neck patient has several possible causes, and one of them is spinal cord compression. Measuring is how you avoid blaming a treatable ear problem on the neck, or a cord problem on age. How a cervicogenic headache is identified.

Is the testing uncomfortable?

No. It is non-invasive and takes under an hour. Some parts bring on brief dizziness by design, which settles quickly. How facet pain is confirmed.

Can neck problems really cause dizziness?

Cervicogenic dizziness is a recognized entity. It is also overdiagnosed. It is a reasonable conclusion after other causes have been ruled out. It is not a reasonable first assumption. What whiplash actually injures.

What if the testing is normal?

That is useful. Normal vestibular function with an abnormal gait moves attention firmly toward the spinal cord and toward proprioceptive causes. That changes what happens next. Headache that starts in the neck.

What conditions do vestibular tests detect?

In someone with neck disease, the testing sorts unsteadiness into its likely cause. The cause is one of these: spinal cord compression from degenerative cervical myelopathy, an inner-ear or central vestibular problem, cervicogenic dizziness from an irritable upper neck, or neuropathy and medication effects. The results separate a peripheral vestibular problem from a central one. They separate both from a balance deficit with normal vestibular function, which points back to the spinal cord.

Is vestibular testing worth it?

Yes, when the complaint is balance rather than pain. A bedside impression picks up early cord compression poorly, and one of the possible causes needs a surgeon quickly. Testing replaces the guess with a measured result. It also gives a baseline to compare a year later. Even a normal result earns its place, because it closes an open question and sends the search somewhere else.

Unsteadiness with normal inner-ear results and brisk reflexes moves the search to the neck. Cervical myelopathy is the cord cause we check for.
