Background
Self-perceptions of aging and physical function
Gait as an indicator of physical function
Aims and hypotheses
-
H1: Higher SPA physical losses is associated with a higher likelihood to exhibit a functionally limited gait pattern when walking at usual gait speed.
-
H2: Higher SPA ongoing development is associated with a higher likelihood of exhibiting a more favorable gait pattern when walking at individual maximum gait speed.
