Short-term effect of the unidirectional rotational rehabilitation on VOR asymmetry. (A) Example of an asymmetric response to sinusoidal rotation in one of the subjects and its improvement after rehabilitation. Dashed lines show 0°/s. (B) Average peak eye velocity (n = 8 subjects) for rotations in the two directions before and after rehabilitation. The side that has larger responses is designated as the side with “higher activity” or HA and the other side as “lower activity” or LA. (C) Directional preponderance as a measure of VOR asymmetry decreased over time. The change is significant between the initial value and all other values (repeated measure ANOVA, p < 0.01). Data for each subject is shown by gray lines.
