Deficits in Selective Attention Alter Gait in Frail Older Adults

A growing body of research demonstrates an association between gait disorders, falls, and attentional capacities in older adults.
The present work empirically analyzes differences in gait parameters in frail institutionalized older adults as a function of selective attention.
Gait analysis under single- and dual-task conditions as well as selective attention measures were collected from a total of 33 nursing-home
residents. We found that differences in selective attention performances were related to the investigated gait parameters. Poorer selective
attention performances were associated with higher stride-to-stride variabilities and a slowing of gait speed under dual-task conditions. The present findings suggest a contribution of selective attention to a safe gait. Implications for gait rehabilitation programs are discussed
