Fig. 1: Time progression of Motion Sickness Questionnaire scores.

Individual scores for the a control group, b active posture group, and c anticipatory cues group are presented. The bottom subplot (d) shows the overlay of median and quartile ranges for all three groups. Filled shapes and solid lines represent actual data points while open shapes and dashed lines represent estimates after a subject dropped out by extrapolation of a linear fit to that subject’s data prior to dropout.
