Examining links between cognitive markers, movement initiation and change, and pedestrian safety in older adults

摘要: Objective: The purpose of this study was to determine the extent which mobility indices (such as walking speed and postural sway), motor initiation, cognitive function, specifically executive functions, including spatial planning, visual attention, within participant variability, differentially predicted collisions in near far sides road with increasing age. Methods: Adults aged over 45 years participated tests measuring function attention (using Useful Field View; UFoV®), assessments (walking speed, sit-to-stand, self-reported mobility, sway assessed using motion capture cameras), gave crossing choices a two-way filmed real traffic pedestrian simulation. Results: A stepwise regression model start-up delay processing speed) explained 49.4% variance near-side errors. Walking measures (average & variability), planning 54.8% far-side unsafe Start-up by only (explained 30.5%). Conclusion: were consistent predictors behaviours. Cognitive measures, however, errors (processing speed), (spatial planning). These findings offer potential contributions for identifying rehabilitating at-risk older pedestrians.
