Subject groups were matched for age, gender, and education. Sleep quality was evaluated based on two-week actigraphy. Gait speed and cognition were assessed as ST and DT performance. DT costs (DTCs) were calculated for both tasks. Outcomes were compared via independent samples t-tests or Mann–Whitney U-tests.Results: Older adults with insomnia demonstrated significantly slower gait speed during ST (1 ± 0.29 vs 1.27 ± 0.17 m/s, p< 0.001) and DT (0.77 ± 0.26 vs 1.14 ± 0.20 m/s, p< 0.001) and fewer correct responses in the cognitive task during ST (21 ± 7 vs 27 ± 11, p=0.009) and DT (19 ± 7 vs 23 ± 9, p=0.015) compared to control group. DTC for the gait task was higher among older adults with insomnia (18.32%, IQR: 9.48– 30.93 vs 7.81% IQR: 4.43– 14.82, p< 0.001). However, no significant difference was observed in DTC for the cognitive task (14.71%, IQR: − 0.89– 38.84 vs 15%, IQR: − 0.89– 38.84%, p=0.599).Conclusion: Older adults with insomnia have lower gait speed and poorer cognitive performance during ST and DT and an inefficient pattern of task prioritization during walking, compared to counterparts without insomnia. These findings may explain the higher risk of falls among older adults with insomnia. Geriatric professionals should be aware of potential interrelationships between sleep and gait.Keywords: actigraphy, sleep quality, gait, dual-task, DTKirshner DKizony RGil EAsraf KKrasovsky THaimov IShochat TAgmon MDove Medical Pressarticleactigraphysleep qualitygaitdual-task (dt)PsychiatryRC435-571Neurophysiology and neuropsychologyQP351-495ENNature and Science of Sleep, Vol Volume 13, Pp 329-338 (2021) |
