Abstract Background Little information exists about the involvement of attention in the control of gait rhythmicity. Variability of both stride time and stride length is closely related to the control of the rhythmic stepping mechanism. We sought I to determine whether backward counting while walking could provoke significant gait changes in mean values and coefficients of variation of stride velocity stride time and stride length among healthy young adults and 2 to establish whether change in stride-to-stride variability could be related to dual-task related stride velocity change attention or both. Methods Mean values and coefficients of variation of stride velocity stride time .
