20.500.12556/RUP-21383 Dual-task gait analysis combined cognitive–motor demands most severely impact walking patterns and joint kinematics Cognitive tasks significantly influence automated acts, such as walking. This study included 41 healthy individuals, who were over 65 years of age. We examined dual-task effects on the spatiotemporal and kinematic parameters of gait in older adults during four tasks carried out in single-task, cognitive, motor, and combined cognitive–motor conditions. An analysis of walking according to spatiotemporal and kinematic parameters was performed using an inertial movement analysis system. The combined task showed the most significant impairments, with substantially reduced gait speed (p < 0.001, r = −0.80), shorter stride length (p < 0.001, r = −0.82), and decreased hip flexion (p < 0.001, r = −0.80) compared to single-task walking. Cognitive tasks alone significantly affected gait speed (p = 0.001) and stride length (p = 0.001), while motor tasks showed minimal effects. The combined task also significantly increased double-support time (p < 0.001) and reduced single-support time (p = 0.001), indicating compensatory walking strategies. These findings demonstrate that concurrent cognitive–motor demands disproportionately impair gait, suggesting that clinical assessments should prioritize combined-task evaluation. The observed kinematic and spatiotemporal changes highlight the profound interdependence between cognitive function and automatic locomotor control during walking. It is likely that dual-task gait analysis may offer clinical utility for the early detection of cognitive–motor deficits. spatiotemporal parameters gait deterioration aging population prostorsko-časovni parametri poslabšanje hoje starajoča populacija true false true Angleški jezik Slovenski jezik Članek v reviji 2025-06-30 08:19:20 2025-06-30 08:19:24 2025-07-01 03:03:21 0000-00-00 00:00:00 2025 0 0 13 str. iss. 7, [article no.] 1009 Vol. 15 2025 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 2025-06-23 2025-06-25 796.01 2075-1729 10.3390/life15071009 240764163 https://www.mdpi.com/2075-1729/15/7/1009 1 14b302c3-557a-11f0-bc14-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=31106 https://doi.org/10.3390/life15071009 1 152d6306-557a-11f0-bc14-005056ac49c0 https://repozitorij.upr.si/Dokument.php?lang=slv&id=31107 Fakulteta za vede o zdravju 0 0 0
