Description
Summary:OBJECTIVES: To investigate dual‐task performance of gait and cognition in cognitively healthy and cognitively impaired older adults using a motor–cognition dual‐task paradigm. DESIGN: Cross‐sectional retrospective study. SETTING: The Basel Memory Clinic and the Basel Study on the Elderly (Project BASEL). PARTICIPANTS: Seven hundred eleven older adults (mean age 77.2 ± 6.2, 350 (49.2%) female and 361 (50.8%) male). MEASUREMENTS: Gait velocity and cognitive task performance using a working memory (counting backward from 50 by 2s) and a semantic memory (enumerating animal names) task were measured during single‐ and dual‐task conditions. Gait was assessed using the GAITRite electronic walkway system. Cognitive impairment was defined as a score less than 25 on the Mini‐Mental State Examination. RESULTS: During dual tasks, participants reduced gait velocity (P.10). Cognitively impaired individuals had lower baseline gait velocity and a greater reduction in gait velocity but not cognitive performance during dual tasks than cognitively healthy participants (P
