Fig. 3From: Improvement of three-dimensional motion sickness using a virtual reality simulator for robot-assisted surgery in undergraduate medical students: A prospective observational studyChanges in SSQ scores with training. Changes in SSQ scores with training are shown. The vertical axis shows the SSQ score, and the horizontal axis shows the training schedule. Gray and black plots show SSQ scores before and after training (mean ± standard deviation), respectively: A, total score (T-SSQ); B, nausea subscore (N-SSQ); C, oculomotor subscore (O-SSQ); and D, disorientation subscore (D-SSQ). *A significant (p < 0.05) difference in scores before and after training on the same day. †A significant (p < 0.05) difference in scores compared to the first day.
