This study examined whether inability to perform adaptive locomotor tests
predicts self-reported incident mobility disability. InCHIANTI study participants
(N = 611; age, 50-85 yrs) who could walk 7 m at self-selected speed and who had
no self-reported mobility disability at baseline were included. The ability to
complete four adaptive locomotor tests was assessed: fast walking, walking on a
narrow path, crossing obstacles while walking, and talking while walking.
Mobility disability was recorded again at 3-yr follow-up. Failure in the
fast-walking and narrow-path walking tests predicted approximately 2.5 times
likelihood of reporting incident mobility disability (P = 0.009 and P = 0.011,
respectively). Failure in the obstacle-crossing test predicted approximately two
times likelihood of reporting incident mobility disability; however, this result
did not reach statistical significance (P = 0.077). Failure in talking while
walking did not predict incident mobility disability. Those who failed both the
fast-walking and narrow-path walking tests were almost nine times as likely to
report incident mobility disability.
