Background: Cognition and gait have often been studied separately after stroke
whereas it has been suggested that these two domains could interact through a
cognitive-motor interference. Objective: To evaluate the influence of gait
changes on cognitive outcome after an ischemic stroke (IS). Methods: We conducted
a prospective and monocentric study including patients admitted for an acute
supratentorial IS with a National Institute of Health Stroke Score ≤ 15.
Cognition, gait and motor disability were evaluated at baseline, 3 months and 1
year post-stroke, using the Montreal Cognitive Assessment (MoCA), the 10-m
walking test (10-MWT) and the Fugl-Meyer motor assessment (FMMA). The effect of
changes in 10-MWT over the year of follow-up on MoCA changes was estimated using
a generalized linear mixed model with FMMA, age and gender as covariates.
Results: Two hundred and Twelve patients were included (71% male, age 64 ± 13
years old). 10-MWT improved from baseline to 1 year (p < 0.001), as did MoCA (p <
0.001) and FMMA (p < 0.001) scores. Ninety-nine patients (47%) had a MoCA
