Although simple assessments of gait speed have been shown to predict falls as well as hospitalisation, functional decline and mortality in older people, dual task gait speed paradigms have been increasingly evaluated with respect to fall prediction. Some studies have found that dual task walking paradigms can predict falls in older people. A systematic review and meta-analysis was conducted to determine whether dual task walking paradigms involving a secondary cognitive task have greater ability to predict falls than single walking tasks. The meta-analytic findings indicate single and dual task tests of gait speed are equivalent in the prediction of falls in older people and sub-group analyses revealed similar findings for studies that included only cognitively impaired participants, slow walkers or used secondary mental-tracking or verbal fluency tasks.
虽然简单的步态速度评估已被证明可以预测老年人的跌倒、住院、功能下降和死亡，但双任务步态速度范式在跌倒预测方面的评估越来越多。一些研究发现，双任务步行范式可以预测老年人的跌倒。进行了系统评价和荟萃分析，以确定涉及次要认知任务的双任务步行范式是否比单一步行任务更能预测跌倒。荟萃分析结果表明，单任务和双任务步态速度测试在预测老年人跌倒方面具有同等能力，亚组分析显示，仅包括认知障碍参与者、慢行者或使用次要心理跟踪或言语流畅性任务的研究也得出了类似的结果。
