Post-stroke deficits in mediolateral foot placement accuracy depend on the prescribed walking task
Description
The primary purposes of this study were to: 1) extend prior investigations of post-stroke mediolateral foot placement accuracy during overground walking to include both stationary and more challenging shifting visual targets; and 2) relate mediolateral paretic foot placement accuracy to paretic hip abduction accuracy. We hypothesized that foot placement accuracy would be reduced for paretic steps in comparison to controls, and that paretic foot placement errors would be correlated with paretic hip abduction errors. This file contains data from both neurologically-intact control participants and people with chronic stroke (PwCS). Specifically, we provide data quantifying mediolateral foot placement error, step width, and walking speed while participants walked on a instrumented mat. In some trials, visual targets prescribing constant step widths were provided, while in other trials the visual targets shifted during the walking trial. We also provide data quantifying the accuracy of the PwCS participants performing an isolated hip abduction task.
