  1. Legend.
  2. SOT: Sensory Organization Test. Normal mean composite scores are 80 for 20–59 years olds (yo) & 77 for 60–69 yo. 5th percentile (abnormal) limits are 69 for 20–59 yo & 70 for 60–69 yo. SOT 5 & 6: Average of Sensory Organization Test scores in conditions 5 (eyes closed, sway referenced platform) & 6 (eyes open, both visual surroundings and platform sway referenced). MCT: Motor Control Test. Normal mean composite scores are 143 for 20–59 yo & 152 for 60–69 yo. 5th percentile (abnormal) limits are 161 for 20–59 yo & 171 for 60–69 yo. VOR: Vestibulo-Ocular Reflex, as tested by 50 deg/s peak sinusoidal vertical axis rotation, 0.05 Hz–1 Hz. Midrange gain (0.2 Hz–1 Hz) and time constant estimated with parametric fit to gain & phase data (based on Dimitri et al., 1996 [21]). N/A: not available. *UVH or (pBVH): Unilateral (UVH) or bilateral vestibular (BVH) hypofunction, based on Dimitri et al., 2002 [22]. If patient is scored as BVH, then the probability of this occurring by chance is given in parentheses. RVR: Reduced vestibular response to bilateral, bithermal caloric stimulation. Response was too low for accurate estimation of time constant; classified as BVH by low VOR gain and low bilateral ice water calorics. **Classified as abnormal by low scores on CDP SOT 5 & 6.
