目的：为了确定步态速度或步行距离是一个更好的预测中风后社区步行。方法：从FIT中风试验的数据被用于横断面设计。社区步行测量与自填问卷。采用5m计时步行和6min步行评估步态速度和步行距离。通过双变量回归分析，检测了步态速度或步行距离与社区步行之间的关系，并确定了可能的混杂因素。采用受试者工作特征曲线（ROC曲线）研究了步行速度和步行距离对社区步行者的判别特性。站立平衡，害怕跌倒和中风后的时间被认为是步态速度和社区步行之间关系的重要混杂因素。步行距离和社区步行之间的关联没有发现显著的混杂因素。步态速度（0.86）、步行距离（0.89）和调整混杂因素后的步态速度（0.89）的ROC曲线下面积差异无统计学意义。结论：步态速度和步行距离同样是脑卒中后社区步行的合适预测指标，而混杂因素的贡献有限。
Objective: To determine if gait speed or walking distance is a better predictor for community walking after stroke.Methods: Data from the FIT-Stroke trial were used in a cross-sectional design. Community walking was measured with a self-administered questionnaire. The 5-m timed walk and the 6-min walk were used to assess gait speed and walking distance. With bivariate regression analyses the association between gait speed or walking distance and community walking was tested and possible confounders were identified. Discriminative properties of gait speed and walking distance for community walking were investigated by means of receiver operating characteristic (ROC) curves.Results: 79% of 241 patients were classified as community walkers. Standing balance, fear of falling and time post-stroke were found to be significant confounders in the relationship between gait speed and community walking. No significant confounders were found for the association between walking distance and community walking. There was no significant difference between the area under the curve of the ROC curves of gait speed (0.86), walking distance (0.89) and gait speed adjusted for confounding (0.89).Conclusion: Gait speed and walking distance are equally appropriate predictors for community walking after stroke, whereas the contribution of confounders is limited.
