(a) Illustrative postural trajectories and 95% confidence interval elliptical fits for each vibration period when the tactor was placed over the left internal oblique. Positive values are defined as movements in the anterior and lateral right directions. (b) Illustrative A/P postural trajectories. Positive values are defined as movements in the anterior direction. (c) Illustrative M/L postural trajectories. Green, red, and blue lines represent pre-, per-, and post-vibration periods, respectively.
