VOR gain and body sway before and after VOR gain adaptation

Eighteen healthy adults stood wearing an inertial measurement device with their eyes closed on foam before and after incremental VOR gain down adaptation. Active head impulse VOR gain was measured before and after the adaptation to ensure VOR gain adaptation. Percentage change for VOR gain was determined. Sway area was compared before and after VOR adaptation. VOR gain decreased unilaterally exceeding meaningful change values. Sway area was significantly greater immediately after VOR gain down adaptation, but quickly returned to baseline.
