VOR x0, VOR x1, VOR x2: they are not easy, medium, and hard. They do three completely different things.
The vestibulo-ocular reflex (VOR) is what keeps your eyes locked on a target while your head moves. Your vestibular system, located just past the eardrum, senses the head movement and drives your eyes in the opposite direction so your vision stays steady.
Here’s how each version works:
VOR x0: The target moves with your head. This tones down the gain of the semicircular canals.
VOR x1: The target stays still while your head moves. This fine tunes and recalibrates the system.
VOR x2: The target moves opposite your head. This increases the gain.
Many vestibular exercise programs treat these as a difficulty ladder. They’re not. Using the wrong one can push an already overactive system harder or suppress one that’s already underactive. That’s why vestibular rehab has to be specific to where the dysfunction actually is.
If you’re dealing with dizziness, blurry vision with head movement, or vestibular dysfunction that isn’t improving, the right exercise matters more than the hardest one.
