Impact of motor fatigue on spatiotemporal parameters of gait under single-and dual-task conditions in individuals with chronic ankle instability and copers

Dual-tasking and fatigue interact to shape gait differently in CAI and coper groups. Rather than uniformly impairing gait, dual-tasking sometimes promoted more consistent walking, while fatigue destabilized gait, particularly in individuals with CAI. These findings highlight the importance of incorporating both cognitive and fatigue-related challenges into rehabilitation to better prepare individuals with CAI for real-world demands.
