Abstract Background Variability in stride velocity during walking characterizes gait instability and predicts falling in older individuals. Walking while executing a cognitive task is also associated with increased risk of falling particularly in older adults. Variability in stride velocity particularly during dual task walking conditions may differ between younger and older individuals. The purpose of this study was to examine whether gait velocity and variability in stride velocity differ between older community-dwelling women and younger women during dual task walking. Methods Twenty-three older 80 9 years and 19 younger 23 2 years women walked under each of two conditions l walking at a self-selected velocity and 2 walking at a self-selected velocity while incrementally counting backwards. Gait velocity and variability in stride velocity were .
