Figure 3From: The effects of actuator selection on non-volitional postural responses to torso-based vibrotactile stimulation(a) Average A/ P postural trajectories. Positive values correspond to movements in the anterior direction. (b) Average M/L postural trajectories. Positive values correspond to movements in the lateral right direction. Red and blue lines represent average postural trajectories for the C2 and Tactaid tactors, respectively. Shaded areas indicate standard error of the corresponding average postural trajectories.Back to article page
