Model parameters for the 3 individual bilateral vestibular loss subjects (▴, *, or □) and mean of control subjects (○) with 95% confidence intervals (error bars or ▩). A: parameters that had fixed values across all test conditions. B: parameters that varied across test conditions. Units on KP are N·m/rad, units on KI are N·m/(rad·s), and units on KD, BV, and BSL are N·m·s/rad. Sensory weight WP1 is unitless. All parameters except WP1 and time delays were normalized by UB mass, m, times UB center-of-mass height, h. The mean m·h was 9.0 kg·m in Cs and 13.2 kg·m in BVLs. Weight parameters WP2 and WV are not shown because they can be derived from WP1. For BVLs in eyes closed conditions, WV = 0 and WP2 = 1 − WP1. In eyes open conditions for BVLs and in all test conditions for Cs, WP2 + WV = 1 − WP1.
