Background. Stroke survivors commonly complain of difficulty sleeping. Poor sleep is associated with reduced quality of life and more understanding of long-term consequences of stroke on sleep is needed. Objective. The primary aims were to (1) compare sleep measures between chronic stroke survivors and healthy controls and (2) test for a relationship between motor impairment, time since stroke and sleep. Secondary aims were to explore mood and inactivity as potential correlates of sleep and test the correlation between self-reported and objective sleep measures. Methods. Cross-sectional sleep measures were obtained for 69 chronic stroke survivors (mean 65 months post-stroke, 63 years old, 24 female) and 63 healthy controls (mean 61 years old, 27 female). Self-reported sleep was assessed with the sleep condition indicator (SCI) and sleep diary ratings, objective sleep with 7-nights actigraphy and mood with the Hospital Anxiety and Depression Scale. Upper extremity motor impairment was assessed with the Fugl-Meyer assessment. Results. Stroke survivors had significantly poorer SCI score (P < .001) and higher wake after sleep onset (P = .005) than controls. Neither motor impairment, nor time since stroke, explained significant variance in sleep measures for the stroke group. For all participants together, greater depression was associated with poorer SCI score (R²_adj = .197, P < .001) and higher age with more fragmented sleep (R²_adj = .108, P < .001). There were weak correlations between nightly sleep ratings and actigraphy sleep measures (r_s = .15–.24). Conclusions. Sleep disturbance is present long-term after stroke. Depressive symptoms may present a modifiable factor which should be investigated alongside techniques to improve sleep in this population.

背景。中风幸存者通常抱怨睡眠困难。睡眠不佳与生活质量下降有关，需要更多地了解中风对睡眠的长期影响。客观的。主要目的是（1）比较慢性中风幸存者和健康对照组之间的睡眠测量，（2）测试运动障碍、中风后时间和睡眠之间的关系。次要目标是探索情绪和不活动作为睡眠的潜在相关因素，并测试自我报告和客观睡眠测量之间的相关性。方法。对 69 名慢性卒中幸存者（平均 65 个月卒中后，63 岁，24 名女性）和 63 名健康对照者（平均 61 岁，27 名女性）进行了横断面睡眠测量。自我报告的睡眠使用睡眠状况指标 (SCI) 和睡眠日记评级、使用 7 晚活动记录仪的客观睡眠和使用医院焦虑和抑郁量表的情绪进行评估。用 Fugl-Meyer 评估法评估上肢运动障碍。结果。中风幸存者的 SCI 评分显着较差（P < .001），入睡后清醒率较高（P= .005) 比控制。运动障碍和中风后的时间都不能解释中风组睡眠测量的显着差异。对于所有参与者，抑郁程度越高，SCI 评分越差（R ² _adj = .197，P < .001），年龄越大，睡眠碎片越多（R ² _adj = .108，P < .001）。夜间睡眠评分与活动记录仪睡眠测量之间的相关性较弱 ( r _s = .15–.24)。结论。中风后长期存在睡眠障碍。抑郁症状可能是一个可改变的因素，应与改善该人群睡眠的技术一起进行调查。
