Dual-Task Decrements in Gait: Contributing Factors Among Healthy Older Adults

摘要

Background. The factors that contribute to the dual tasking (DT) changes in performance that occur when older adults walk while simultaneously performing other tasks are not well known. We hypothesized that cognitive and motor reserve (e.g., executive function [EF], postural control, and walking abilities) and affect (e.g., anxiety, depressive symptoms) influence the DT decrements (DTDs) in gait.
