Objective
To determine if poorer gait variability and gait coordination among mobility-limited older adults is related to their slower walking speed. Design Cross-sectional analysis. Setting University research laboratory. Participants Community-dwelling adults (N=69) 68 years or older with (Short Physical Performance Battery score ≤9; n=37) and without (n=32) mobility limitations. Interventions Not applicable. Main Outcome Measures The variability of step length, swing time percent, and step width. Gait coordination was assessed along with the Phase Coordination Index. Results The usual pace gait speed of those without mobility limitations was faster (1.22±0.14m/s vs 0.71±0.14m/s; P<.001 and less variable in all gait characteristics p with the exception of step width than those limitations. when without limitations slowed their walking pace coordination became poorer variability increased except for which decreased mobility walked at a slow they had better length swing time percent stride were not significantly different that peers> Conclusions Increased variability in some gait characteristics of mobility-limited older adults appears to be related to their slower walking speed. Gait coordination and the variability of step length and swing time percent may reflect intrinsic differences in mobility-limited older adults that are independent of walking speed. |
