Inter-Step Height Variation Of Stairways And Observations Of Fall-Related Events, Chayston B. Brown, Shandon Poulsen, Chris Dakin, Sara Harper, Tyson Barrett
International Journal of Exercise Science: Conference Proceedings
INTRODUCTION: Variation in step height within a stairway could negatively impact safe stairway negotiation by decreasing step height predictability, and consequently, increasing stair users’ fall risk. Unfortunately, inter-stairway step height variability is common, particularly in older stairways, but its impact may be lessened by highlighting steps’ edges using high-contrast stripes on the top front edge of each step. Such contrast enhancement may draw greater attention to the steps’ edges and potentially enhance the precision of the edge’s estimated location. PURPOSE: To determine (1) if fall-related events are associated with greater inter-step height variation, and (2) if such fall-related events are …
