A Measurement of gaze behavior with a Mobile Eye Tracker. Gaze time for all areas of interest was expressed as a percentage of the total trial duration. B 24 patients with vestibular disorder (mean age of 63.2 years, 8 male) 24 healthy adults (mean age: 56.0 years, SD: 13.8, 10 male) Lower Transition Phase Stair Structure Upper Transition Phase Elsewhere C % Gaze time Additional focus on the stair may compensate for the vestibular loss. Patients with chronic vestibulopathy were more focused on the stair during stair walking, however, not during the lower stair-floor transition phase, where accidents typically happen.
