Which clinical measures of walking performance best predict free-living physical activity in community-dwelling people with stroke?
Cross-sectional observational study.
42 community-dwelling stroke survivors.
Predictors were four clinical measures of walking performance (speed, automaticity, capacity, and stairs ability). The outcome of interest was free-living physical activity, measured as frequency (activity counts) and duration (time on feet), collected using an activity monitor called the Intelligent Device for Energy Expenditure and Physical Activity.
Time on feet was predicted by stairs ability alone (B 166, 95% CI 55 to 278) which accounted for 48% of the variance. Activity counts were also predicted by stairs ability alone (B 6486, 95% CI 2922 to 10 050) which accounted for 58% of the variance.
The best predictor of free-living physical activity in community-dwelling people with stroke was stairs ability.
对于社区中患有中风的居民，哪种步行能力的临床测量指标能最好地预测其日常身体活动情况？
横断面观察性研究。
42名社区中风幸存者。
预测指标为步行能力的四项临床测量指标（速度、自主性、能力和爬楼梯能力）。感兴趣的结果是日常身体活动，通过使用名为“能量消耗与身体活动智能设备”的活动监测器收集的频率（活动计数）和持续时间（站立时间）来衡量。
仅爬楼梯能力可预测站立时间（B 166，95%可信区间55至278），其解释了48%的方差。仅爬楼梯能力也可预测活动计数（B 6486，95%可信区间2922至10050），其解释了58%的方差。
对于社区中患有中风的居民，日常身体活动的最佳预测指标是爬楼梯能力。
