Popis: Background. Individuals with multiple sclerosis (MS) experience deficits in motor and cognitive domains, resulting in impairment in dual-task walking ability. The goal of this study was to compare performance of forward walking and backward walking in single- and dual-task conditions in persons with MS to age- and sex-matched healthy controls. We also examined relationships between forward and backward walking to cognitive function, balance, and retrospective fall reports. Methods. All measures were collected in a single session. A 2×2×2 mixed model ANOVA was used to compare differences in forward and backward walking in single- and dual-task conditions between MS and healthy controls. Spearman correlations were used to examine relationships between gait and cognitive function, falls, and balance. Results. Eighteen individuals with relapsing-remitting MS and 14 age- and sex-matched healthy controls participated. Backward walking velocity revealed significant differences between groups for both single-task (p=0.015) and dual-task (p=0.014) conditions. Persons with MS demonstrated significant differences between single- and dual-task forward and backward walking velocities (p=0.023; p=0.004), whereas this difference was only apparent in the backward walking condition for healthy controls (p=0.004). In persons with MS, there were significant differences in double support time between single- and dual-task conditions in both backward (p
