If you have been through the Epley maneuver twice, had a clean MRI, and still feel unsteady every time you turn your head, the problem may not be in your ear. Patients arrive at Draper Spinal Care after months of this loop, carrying a diagnosis of benign positional vertigo that never quite fit. What they often have instead is cervicogenic dizziness, a balance disturbance driven by dysfunction in the upper neck rather than the vestibular system.
It is a recognized condition, and also the one most likely to be missed, because no single scan or blood test confirms it.
What is cervicogenic dizziness?
Cervicogenic dizziness is a sensation of unsteadiness, floating, or disorientation that originates from abnormal sensory input coming out of the neck. It is diagnosed by exclusion, meaning a clinician arrives at it after ruling out inner ear, neurological, and vascular causes.
The mechanism is proprioceptive. Your brain calculates where your head is in space by blending input from the inner ear, the eyes, and position sensors in the deep muscles and joints of the cervical spine. The small suboccipital muscles at the base of the skull carry an unusually dense supply of muscle spindles, the receptors that report stretch and position, at concentrations far higher per gram of tissue than large limb muscles. Those signals feed into the same vestibular nuclei that process inner ear information. When joint motion at C1 and C2 is restricted or the surrounding musculature is guarded, the neck sends distorted data, and the brain has to reconcile a mismatch between what the ear reports and what the neck reports. That mismatch is what you feel as dizziness.
How is it different from true vertigo?
The clearest distinction is the quality of the sensation and what sets it off. True vertigo is a spinning illusion, as though the room is rotating. Cervicogenic dizziness more often feels like swimming, drifting, or walking on a boat deck, and patients frequently describe it as being off rather than spinning.
Timing separates them further. A few patterns worth knowing:
- Benign paroxysmal positional vertigo produces intense spinning that lasts under a minute, triggered by rolling over in bed or tipping the head back, and is identified with the Dix-Hallpike test
- Vestibular neuritis comes on suddenly and severely, lasts days rather than minutes, and often follows a viral illness
- Ménière’s disease brings episodes of 20 minutes to 12 hours paired with fluctuating hearing loss, tinnitus, and a sense of fullness in the ear
- Vestibular migraine episodes run anywhere from 5 minutes to 72 hours and usually appear in someone with a migraine history
- Cervicogenic dizziness tends to last minutes to hours, tracks with neck pain or stiffness, and worsens with sustained or repeated head positions
Hearing symptoms are the practical dividing line. Cervicogenic dizziness does not cause hearing loss or tinnitus. If either is present, the inner ear needs evaluation first.
What causes the neck to start sending bad signals?
Whiplash is the most common trigger. Research on whiplash-associated disorders has consistently found dizziness among the more frequently reported symptoms, with figures across studies commonly landing somewhere between 20 and 50 percent of patients.
Other origins are less dramatic and easier to overlook. Sustained forward head posture at a desk, an old sports injury, arthritic change in the upper cervical joints, or a fall that seemed minor can all leave the segment moving poorly. Onset is often delayed by weeks, which is part of why patients rarely connect the dizziness to the neck event themselves.
How do you test for it?
Several clinical tests help separate cervical from vestibular input, and the most useful is the cervical torsion test. The patient’s head is held still while the trunk is rotated underneath it, which changes neck position without moving the inner ear. If symptoms reproduce, the neck is implicated.
The joint position error test adds an objective number. A laser is fixed to the head, the patient memorizes a target, closes their eyes, turns the head, then attempts to return to the starting point. Errors beyond roughly 4.5 degrees are generally considered abnormal and point toward impaired cervical proprioception. The smooth pursuit neck torsion test compares eye tracking with the trunk neutral against the trunk rotated.
Some symptoms mean skipping all of this and seeking emergency care instead. Sudden severe vertigo accompanied by double vision, slurred speech, difficulty swallowing, facial numbness, weakness, or an inability to walk can signal a problem in the posterior circulation of the brain and requires immediate evaluation.
What does treatment look like at Draper Spinal Care?
Care begins with restoring normal motion and alignment to the upper cervical spine, then retraining the proprioceptive system that has been running on faulty input. Published reviews of manual therapy for cervicogenic dizziness, including work by Reid and Rivett, report that most patients improve, though the authors are candid that study quality is moderate and sample sizes have been small.
A typical course runs four to eight weeks, with reassessment along the way. Gentle, low-force upper cervical work suits this population, since aggressive rotational technique can provoke symptoms in someone whose balance system is already irritable. Eye-head coordination drills and joint position retraining get added once motion improves, and posture changes at work matter more here than patients expect.
Dizziness that has outlasted a normal inner ear workup deserves a look at the neck before you accept that nothing can be done. If head position reliably changes how you feel, that is a clue worth following, and the team at Draper Spinal Care can tell you within an exam or two whether the cervical spine is the piece that has been missed.
