From: Age dependent normal horizontal VOR gain of head impulse test as measured with video-oculography
a: Normal HVOR velocity gain at 80 ms decline with age. HVOR velocity gain was found to decline by 0.012 per decade with increasing age (95 % CI 0.001 to 0.022; p = 0.028). HVOR velocity gain is the ratio of angular eye velocity to angular head velocity. b: Normal HVOR velocity gain at 60 ms decline with age. HVOR velocity gain was found to decline by 0.017 per decade with increasing age 95 %CI 0.006 – 0.029; p = 0.005). HVOR velocity gain is the ratio of angular eye velocity to angular head velocity
