What Are VOR Exercises and How Do They Work?
VOR stands for vestibulo-ocular reflex. It is the fastest reflex in the human body, firing in about ten milliseconds to keep your gaze stable while your head moves. VOR exercises deliberately stress that reflex so the brain recalibrates it after inner ear damage. The movement looks trivial from outside and feels like work from inside.
What is the vestibulo-ocular reflex?
The vestibulo-ocular reflex links the inner ear's semicircular canals to the muscles that move your eyes. When your head turns one way, the canals sense it and drive your eyes the opposite way at matching speed, holding the image still on your retina. Without it, every step would smear your vision like a shaky camera.
You can feel the reflex working right now. Hold a finger up, keep your eyes on it, and shake your head no. The finger stays sharp because your eyes counter-rotate automatically. Now move the finger side to side while holding your head still and try to track it; it blurs sooner, because smooth pursuit is slower than the reflex. That gap is the whole point of VOR training.
What is the difference between VOR x1 and VOR x2?
In VOR x1, the target stays still and only your head moves, so the reflex must match head speed exactly. In VOR x2, you move the target one way and your head the other, doubling the demand on the reflex. X1 is the starting exercise; x2 is the progression once x1 feels controlled and the target stays sharp.
| Exercise | Target | Head | Demand on reflex |
|---|---|---|---|
| VOR x1 | Held still | Turns side to side | Match head speed |
| VOR x2 | Moves opposite the head | Turns toward the target's old spot | Roughly double |
Most programs start with x1 in the horizontal plane, add the vertical plane, then introduce x2 once the easier version no longer blurs. Progressing too fast is a common error that floods you with symptoms and stalls adaptation.
How do you coach head speed without watching a screen?
The reflex only retrains when your eyes stay on a fixed target, so anything that pulls your gaze toward a phone undercuts the rep. SteadyGaze solves this by reading head speed through the AirPods motion sensor and coaching pace with sound, leaving your eyes free to hold the wall target the entire session.

Who should do VOR exercises?
VOR exercises help people with stable, one-sided or two-sided vestibular loss, including vestibular neuritis, labyrinthitis, post-concussion dizziness and some forms of PPPD. They are less useful during an active BPPV attack, which needs repositioning maneuvers first. A clinician should confirm the cause of your dizziness before you start a VOR program.
For unilateral peripheral loss the evidence is strong: the National Institute on Deafness and Other Communication Disorders and multiple Cochrane reviews back vestibular rehab as a first-line treatment. The reflex can recalibrate even years after the original injury, which is why people who never did rehab still improve when they finally start.
Key takeaways
- VOR exercises train the vestibulo-ocular reflex, which keeps vision steady during head movement.
- VOR x1 keeps the target still; VOR x2 moves the target opposite your head and roughly doubles the demand.
- Start with x1 horizontal, add vertical, then progress to x2 when the target stays sharp.
- Eyes must stay on the target, so audio pacing beats screen-based feedback.
- VOR rehab has strong evidence for stable one-sided vestibular loss.
Frequently asked questions
- What does VOR stand for?
- VOR stands for the vestibulo-ocular reflex. It is the automatic circuit connecting your inner ear balance sensors to your eye muscles. When your head moves, the reflex drives your eyes the opposite direction at equal speed so the image on your retina stays still. VOR exercises retrain that reflex when inner ear damage throws its calibration off.
- How fast should I move my head during VOR exercises?
- Fast enough that the target is on the edge of blurring but still readable, and no faster. The blur threshold is your guide. If the letter doubles or smears, slow down until it sharpens, then creep the speed back up. Pushing past the point where you can read the target trains nothing and only stacks up symptoms.
- Can VOR exercises make dizziness worse?
- They can provoke mild, temporary dizziness, which is expected. Trouble comes from doing too much too soon: long sets, high speed, or skipping the gentle x1 stage. Symptoms should settle within a few minutes of stopping. If they last hours or build day to day, scale back the duration and pace and check in with your clinician.
- Do I need AirPods to do VOR exercises?
- No, the exercises work with just a wall target and your head. AirPods let SteadyGaze measure head speed and coach pace by sound, which is hard to self-judge. Without compatible AirPods, the app still runs as a guided metronome with a manual log, so you can practice while deciding whether to add motion coaching.
