Relative Association of Processing Speed, Short-Term Memory and Sustained Attention With Task on Gait Speed: A Study of Community-Dwelling People 50 Years and Older

摘要: Background. For single gait tasks, associations have been reported between speed and cognitive domains. However, few studies evaluated if this association is altered in dual tasks given changes with complexity nature of task. We relative contributions specific elements function (including sustained attention processing speed) to task a nationally representative population community-dwelling adults over 50 years. METHODS: Gait was obtained using the GaitRite walkway during three tasks: single, (alternate letters), motor (carrying filled glass). Linear regression models, adjusted for covariates, were constructed predict seven neuropsychological tests differences investigate effects. RESULTS: The mean age (n = 4,431, 55% women) 62.4 years (SD 8.2) 135.85 cm/s 20.20, task), respectively. Poorer speed, short-term memory, major contributors slower all tasks. Both robust covariate adjustment had significant additional executive element not found CONCLUSIONS: older memory independently associated Dual highlight elements. This result forms baseline value speed. Language: en
