abstract = {Objectives: To analyze which gait parameters are primarily
influenced by cognitive flexibility, and whether such an
effect depends on the walking condition used. Design:
Cross-sectional analysis. Setting: Tübingen evaluation of
Risk factors for Early detection of Neurodegenerative
Disorders. Participants: A total of 661 non-demented
individuals (49-80 years). Measurements: A gait assessment
with four conditions was performed: a 20 m walk at
convenient speed (C), at fast speed (F), at fast speed while
checking boxes (FB), and while subtracting serial 7s (FS).
Seven gait parameters from a wearable sensor-unit
(McRoberts, Netherlands) were compared with delta
Trail-Making-Test (dTMT) values, which is a measure of
cognitive flexibility. Walking strategies of good and poor
dTMT performers were compared by evaluating the patterns of
gait parameters across conditions. Results: Five parameters
correlated significantly with the dTMT in the FS condition,
two parameters in the F and FB condition, and none in the C
condition. Overall correlations were relatively weak. Gait
speed was the gait parameter that most strongly correlated
with the dTMT (r2 = $7.4\%).$ In good, but not poor, dTMT
performers differences between FB and FS were significantly
different in variability-associated gait parameters.
Conclusion: Older individuals need cognitive flexibility to
perform difficult walking conditions. This association is
best seen in gait speed. New and particularly relevant for
recognition and training of deficits is that older
individuals with poor cognitive flexibility have obviously
fewer resources to adapt to challenging walking conditions.
Our findings partially explain gait deficits in older adults
with poor cognitive flexibility.},
