Dual-Task Walking Across Task Combinations in Older Adults With Mild Cognitive Impairment

Dual-task activities, combining gait and cognitive processes, are associated with fall risk and are therefore commonly evaluated in physical therapy care for older adults. Both aMCI and NC groups walked slower during dual-task conditions, but the aMCI group experienced changes with a lower cognitive load. This highlights the importance of quantifying both cognitive and gait performance during dual-task assessments. Changes in cognitive task and gait performance were consistent across different dual-task combinations, which could inform dual-task interventions.
