Optokinetic & VOR practice

Desktop drills for quick head turns, tall swaying visuals, and visually induced dizziness. Local GPU stimuli first — no video compress. MRI-negative / not BPPV framing.

What this is for

When vision and the inner ear disagree — busy visual motion, abrupt head turns, alcohol “unmasking” an off day — you can get nausea, veering, or that sea-sick feeling while still. These drills gently retrain that link (VOR ×1, optokinetic tracking, eye–head substitution, seated habituation). They are not canalith-repositioning maneuvers (no Epley / Semont / Brandt-Daroff here).

Expect weeks 1–2 to feel harder; clearer head turns often show by weeks 3–6. Alcohol may still provoke — do not train intoxicated or hungover.

Nausea gate: rate symptoms 0–10. Stay ≤5 during bouts. Stop the bout if you go above 5; mild “off” usually settles in about 15 minutes. Mild ≤5 is expected training load — strong nausea is too much.

Safety

Skip if: you have acute BPPV spinning attacks your clinician is treating with repositioning — those maneuvers are intentionally omitted from this suite.
