  1. Legend:
  2. SOT Sensory Organization Test, Normal mean composite scores are 80 for 20-59 years old (yo) & 77 for 60-69 yo; 5th percentile (abnormal limits) scores are 69 for 20-59 yo & 70 for 60-69 yo.
  3. MCT Motor Control Test, Normal mean composite scores are 143 for 20-59 yo & 152 for 60-69 yo; 5th percentile (abnormal limits) scores are 161 for 20-59 yo & 171 for 60-69 yo.
  4. N/A Not available.
  5. VOR Vestibuloocular reflex, as tested by 50 deg/sec peak sinusoidal vertical axis rotation, 0.01-1 Hz.
  6. Midrange gain (0.2-1 Hz) and time constant estimated with parametric fit to gain and phase data (based on Dimitri et al., 1996).
  7. † Response was too low for accurate estimation of time constant; classified as BVH by low VOR gain and low bilateral ice water calorics.
  8. UVH or BVH, diagnostic classification as unilateral or bilateral vestibular hypofunction.
