Gait speed is recognized as an important predictor of adverse outcomes in older people. However, it is unknown whether other more complex mobility tasks are better predictors of such outcomes.
To examine a range of clinic-based mobility tests and determine which were most strongly associated with measures of community performance and risk (CP&R).
Cross-sectional study.
Central Control Mobility and Aging Study, Westchester County, New York.
Aged ≥65 years (n = 424).
Clinic-based mobility measures included gait speed measured during normal and dual-task conditions, the Floor Maze Immediate and Delay tasks, and stair ascending and descending. CP&R measures were self-reported by the use of standardized questionnaires and classified into measures of performance (distance walked, travel outside one's home [life space], activities of daily living, and participation in cognitive leisure activities) or risk (balance confidence, fear of falling, and past falls). Linear and logistic regression were used to examine associations between the clinic-based mobility measures and CP&R measures adjusting for covariates.
The mean age of the sample was 77.8 (SD 6.4) years, and 55.2% (n = 234) were female. In final models, faster normal walking speed was most strongly associated with 5 of the 7 community measures (greater distance walked, greater life space, better activities of daily living function, higher balance confidence, and less fear of falling; all P < .05). More complex tasks (walking while talking and maze immediate) were associated with cognitive leisure activity (P < .05), and ascending stairs was the only measure associated with a history of falls (P < .05).
Normal walking speed is a simple and inexpensive clinic-based mobility test that is associated with a wide range of CP&R measures. In addition, poorer performance ascending stairs may assist in identifying those at risk of falls. Poorer performance in more complex mobility tasks (walking while talking and maze immediate) may suggest inability to participate in cognitive leisure activities.

步速被认为是老年人不良结局的重要预测指标。然而，目前尚不清楚其他更复杂的移动任务是否是这些结果的更好预测指标。
检查一系列基于诊所的移动测试，并确定哪些测试与社区表现和风险（CP&R）的衡量标准相关性最强。
横断面研究。
纽约州威彻斯特县中央控制移动与衰老研究。
年龄≥65 岁（n=424）。
基于诊所的移动测量包括在正常和双重任务条件下测量的步速、地板迷宫即时和延迟任务以及上下楼梯。CP&R 测量由使用标准化问卷进行自我报告，并分为表现（行走距离、离家外出[生活空间]、日常生活活动和参与认知休闲活动）或风险（平衡信心、跌倒恐惧和过去跌倒）的测量。使用线性和逻辑回归来检验基于诊所的移动测量与 CP&R 测量之间的关联，调整协变量。
样本的平均年龄为 77.8（SD 6.4）岁，55.2%（n=234）为女性。在最终模型中，正常行走速度越快与 7 项社区测量中的 5 项（行走距离更大、生活空间更大、日常生活活动功能更好、平衡信心更高、跌倒恐惧更少；所有 P<.05）相关性最强。更复杂的任务（边走路边说话和即时走迷宫）与认知休闲活动相关（P<.05），而上楼梯是唯一与跌倒史相关的测量（P<.05）。
正常行走速度是一种简单且经济实惠的基于诊所的移动测试，与广泛的 CP&R 测量相关。此外，上楼梯表现较差可能有助于识别跌倒风险。更复杂的移动任务（边走路边说话和即时走迷宫）表现较差可能表明无法参与认知休闲活动。
