| 520 | |a Background: Real-world mobility involves walking in challenging conditions. Assessing gait during simultaneous physical and cognitive challenges provides insights on cognitive health.Research question: How does uneven surface, cognitive task, and their combination affect gait quality and does this gait performance relate to cognitive functioning?Methods: Community-dwelling older adults (N = 104, age=75 ± 6 years, 60 % females) performed dual-task walking paradigms (even and uneven surface; with and without alphabeting cognitive task (ABC)) to mimic real-world demands. Gait quality measures [speed(m/s), rhythmicity(steps/minute), stride time variability (%), adaptability (m/s2), similarity, smoothness, power (Hz) and regularity] were calculated from an accelerometer worn on the lower back. Linear-mixed modelling and Tukey analysis were used to analyze independent effects of surface and cognitive task and their interaction on gait quality. Partial Spearman correlations compared gait quality with global cognition and executive function.Results: No interaction effects between surface and cognitive task were found. Uneven surface reduced gait speed(m/s) (β = –0.07). Adjusted for speed, uneven surface reduced gait smoothness (β = –0.27) and increased regularity (β = 0.09), Tukey p < .05, for even vs uneven and even-ABC vs uneven-ABC. Cognitive task reduced gait speed(m/s) (β = –0.12). Adjusted for speed, cognitive task increased variability (β = 7.60), reduced rhythmicity (β = –6.68) and increased regularity (β = 0.05), Tukey p < .05, for even vs even-ABC and uneven vs uneven-ABC. With demographics as covariates, gait speed was not associated with cognition. Gait quality [lower variability during even-ABC (ρp =–.31) and uneven-ABC (ρp =–.28); greater rhythmicity (ρp between.22 and.29) and greater signal-adaptability AP (ρp between.22 and.26) during all walking tasks] was associated with better global cognition. Gait adaptability during even (ρp =–0.21, p = 0.03) and uneven(ρp =–0.19, p = 0.04) walking was associated with executive function.Significance: Surface and cognitive walking tasks independently affected gait quality. Our study with high-functioning older adults suggests that task-related changes in gait quality are related to subtle changes in cognitive functioning. | ||

Adjusted for speed, cognitive task increased variability (β = 7.60), reduced rhythmicity (β = –6.68) and increased regularity (β = 0.05), Tukey p < .05, for even vs even-ABC and uneven vs uneven-ABC. With demographics as covariates, gait speed was not associated with cognition. Gait quality [lower variability during even-ABC (ρp =–.31) and uneven-ABC (ρp =–.28); greater rhythmicity (ρp between.22 and.29) and greater signal-adaptability AP (ρp between.22 and.26) during all walking tasks] was associated with better global cognition. Gait adaptability during even (ρp =–0.21, p = 0.03) and uneven(ρp =–0.19, p = 0.04) walking was associated with executive function.Significance: Surface and cognitive walking tasks independently affected gait quality. Our study with high-functioning older adults suggests that task-related changes in gait quality are related to subtle changes in cognitive functioning.

Assessing gait during simultaneous physical and cognitive challenges provides insights on cognitive health.Research question: How does uneven surface, cognitive task, and their combination affect gait quality and does this gait performance relate to cognitive functioning?Methods: Community-dwelling older adults (N = 104, age=75 ± 6 years, 60 % females) performed dual-task walking paradigms (even and uneven surface; with and without alphabeting cognitive task (ABC)) to mimic real-world demands. Gait quality measures [speed(m/s), rhythmicity(steps/minute), stride time variability (%), adaptability (m/s2), similarity, smoothness, power (Hz) and regularity] were calculated from an accelerometer worn on the lower back. Linear-mixed modelling and Tukey analysis were used to analyze independent effects of surface and cognitive task and their interaction on gait quality.

Uneven surface and cognitive dual-task independently affect gait quality in older adults |
| abstract |
Background: Real-world mobility involves walking in challenging conditions. Assessing gait during simultaneous physical and cognitive challenges provides insights on cognitive health.Research question: How does uneven surface, cognitive task, and their combination affect gait quality and does this gait performance relate to cognitive functioning?Methods: Community-dwelling older adults (N = 104, age=75 ± 6 years, 60 % females) performed dual-task walking paradigms (even and uneven surface; with and without alphabeting cognitive task (ABC)) to mimic real-world demands. Gait quality measures [speed(m/s), rhythmicity(steps/minute), stride time variability (%), adaptability (m/s2), similarity, smoothness, power (Hz) and regularity] were calculated from an accelerometer worn on the lower back. Linear-mixed modelling and Tukey analysis were used to analyze independent effects of surface and cognitive task and their interaction on gait quality. Partial Spearman correlations compared gait quality with global cognition and executive function.Results: No interaction effects between surface and cognitive task were found. Uneven surface reduced gait speed(m/s) (β = –0.07). Adjusted for speed, uneven surface reduced gait smoothness (β = –0.27) and increased regularity (β = 0.09), Tukey p < .05, for even vs uneven and even-ABC vs uneven-ABC. Cognitive task reduced gait speed(m/s) (β = –0.12). Adjusted for speed, cognitive task increased variability (β = 7.60), reduced rhythmicity (β = –6.68) and increased regularity (β = 0.05), Tukey p < .05, for even vs even-ABC and uneven vs uneven-ABC. With demographics as covariates, gait speed was not associated with cognition. Gait quality [lower variability during even-ABC (ρp =–.31) and uneven-ABC (ρp =–.28); greater rhythmicity (ρp between.22 and.29) and greater signal-adaptability AP (ρp between.22 and.26) during all walking tasks] was associated with better global cognition. Gait adaptability during even (ρp =–0.21, p = 0.03) and uneven(ρp =–0.19, p = 0.04) walking was associated with executive function.Significance: Surface and cognitive walking tasks independently affected gait quality. Our study with high-functioning older adults suggests that task-related changes in gait quality are related to subtle changes in cognitive functioning. |

Assessing gait during simultaneous physical and cognitive challenges provides insights on cognitive health.Research question: How does uneven surface, cognitive task, and their combination affect gait quality and does this gait performance relate to cognitive functioning?Methods: Community-dwelling older adults (N = 104, age=75 ± 6 years, 60 % females) performed dual-task walking paradigms (even and uneven surface; with and without alphabeting cognitive task (ABC)) to mimic real-world demands. Gait quality measures [speed(m/s), rhythmicity(steps/minute), stride time variability (%), adaptability (m/s2), similarity, smoothness, power (Hz) and regularity] were calculated from an accelerometer worn on the lower back. Linear-mixed modelling and Tukey analysis were used to analyze independent effects of surface and cognitive task and their interaction on gait quality. Partial Spearman correlations compared gait quality with global cognition and executive function.Results: No interaction effects between surface and cognitive task were found. Uneven surface reduced gait speed(m/s) (β = –0.07). Adjusted for speed, uneven surface reduced gait smoothness (β = –0.27) and increased regularity (β = 0.09), Tukey p < .05, for even vs uneven and even-ABC vs uneven-ABC. Cognitive task reduced gait speed(m/s) (β = –0.12). Adjusted for speed, cognitive task increased variability (β = 7.60), reduced rhythmicity (β = –6.68) and increased regularity (β = 0.05), Tukey p < .05, for even vs even-ABC and uneven vs uneven-ABC. With demographics as covariates, gait speed was not associated with cognition. Gait quality [lower variability during even-ABC (ρp =–.31) and uneven-ABC (ρp =–.28); greater rhythmicity (ρp between.22 and.29) and greater signal-adaptability AP (ρp between.22 and.26) during all walking tasks] was associated with better global cognition. Gait adaptability during even (ρp =–0.21, p = 0.03) and uneven(ρp =–0.19, p = 0.04) walking was associated with executive function.Significance: Surface and cognitive walking tasks independently affected gait quality. Our study with high-functioning older adults suggests that task-related changes in gait quality are related to subtle changes in cognitive functioning.</subfield></datafield><datafield tag="650"
