Gain values for high acceleration transients and sinusoidal rotation in patients and normal controls

		Mean transient gain		Sinusoidal gain 0.8 Hz
		Centred rotations 25–100 ms	Eccentric rotations 25–100 ms	Sinusoidal gain 0.8 Hz
Patient 1	0.05 (0.006)	0.12 (0.007)	0.58
Patient 2	0.27 (0.004)	0.29 (0.005)	0.72
Patient 3	0.04 (0.007)	0.08 (0.006)	0.30
Patient 4	0.03 (0.005)	0.03 (0.005)	0.42
Normal subjects^1-150	0.88 (0.002)^1-152	0.95 (0.002)^1-152	0.71 (0.18)^1-151

Transient gain values are mean (CW+CCW)/2 SEM).
↵1-150 Normal controls (n=11).
