Poor sleep quality constitutes one of the most common difficulties faced by stroke survivors. Physical activity has been shown to improve sleep quality among healthy adults. The study objective was to examine the effect of physical activity on sleep outcomes in community-dwelling stroke survivors previously enrolled in a randomized clinical trial (RCT). Secondary analysis of data collected in the RCT was used to examine the effects of physical activity (PA) on sleep outcomes using the Pittsburgh Sleep Quality Index (PSQI), compared to usual care (controls). Unadjusted and adjusted mixed effects models were used to model changes in sleep quality between groups. At baseline, poor sleep quality (PSQI > 5) was reported by about half of the participants (PA group = 48.5%, n = 47/97; controls = 56.3%, n = 27/48). Results from the unadjusted and adjusted models for sleep quality were similar and showed no statistically significant differences between groups ( > 0.05). In the unadjusted model, the difference between groups (change from baseline to 24 weeks) showed that the PA group had better sleep quality than the controls (difference= -1.02 points, 95% CI -2.12, 0.07, = 0.07). In the model adjusted for age, social support, and marital status, the difference between groups (change from baseline to 24 weeks) showed that the PA group had better sleep quality than the controls (difference= -1.07 points, 95% CI -2.19, 0.05, = 0.06). PA did not significantly improve sleep quality in older community-dwelling stroke survivors. Further research is needed to confirm or refute these findings.
睡眠质量差是中风幸存者最常见的困难之一。身体活动已被证明能改善健康成年人的睡眠质量。本研究目的是检验身体活动对先前参加过随机临床试验（RCT）的社区居住中风幸存者睡眠结果的影响。使用匹兹堡睡眠质量指数（PSQI）对 RCT 中收集的数据进行二次分析，以检验身体活动（PA）对睡眠结果的影响，与常规护理（对照组）进行比较。使用未调整和调整后的混合效应模型来模拟组间睡眠质量的变化。在基线时，大约一半的参与者（PA 组=48.5%，n=47/97；对照组=56.3%，n=27/48）报告睡眠质量差（PSQI>5）。未调整和调整后的睡眠质量模型的结果相似，组间无统计学差异（>0.05）。在未调整模型中，组间差异（从基线到 24 周的变化）显示 PA 组的睡眠质量优于对照组（差异=-1.02 分，95%CI-2.12，0.07，=0.07）。在调整年龄、社会支持和婚姻状况的模型中，组间差异（从基线到 24 周的变化）显示 PA 组的睡眠质量优于对照组（差异=-1.07 分，95%CI-2.19，0.05，=0.06）。PA 并未显著改善老年社区居住中风幸存者的睡眠质量。需要进一步研究来证实或反驳这些发现。
