BACKGROUND
Physical activity and exercise appear to improve sleep quality. However, the quantitative effects of Tai Chi on sleep quality in the adult population have rarely been examined. We conducted a systematic review and meta-analysis evaluating the effects of Tai Chi on sleep quality in healthy adults and disease populations.
METHODS
Medline, Cochrane Central databases, and review of references were searched through July 31, 2013. English-language studies of all designs evaluating Tai Chi's effect on sleep outcomes in adults were examined. Data were extracted and verified by 2 reviewers. Extracted information included study setting and design, population characteristics, type and duration of interventions, outcomes, risk of bias and main results. Random effect models meta-analysis was used to assess the magnitude of treatment effect when at least 3 trials reported on the same sleep outcomes.
RESULTS
Eleven studies (9 randomized and 2 non-randomized trials) totaling 994 subjects published between 2004 and 2012 were identified. All studies except one reported Pittsburg Sleep Quality Index. Nine randomized trials reported that 1.5 to 3 hour each week for a duration of 6 to 24 weeks of Tai Chi significantly improved sleep quality (Effect Size, 0.89; 95% confidence interval [CI], 0.28 to 1.50), in community-dwelling healthy participants and in patients with chronic conditions. Improvement in health outcomes including physical performance, pain reduction, and psychological well-being occurred in the Tai Chi group compared with various controls.
LIMITATIONS
Studies were heterogeneous and some trials were lacking in methodological rigor.
CONCLUSIONS
Tai Chi significantly improved sleep quality in both healthy adults and patients with chronic health conditions, which suggests that Tai Chi may be considered as an alternative behavioral therapy in the treatment of insomnia. High-quality, well-controlled randomized trials are needed to better inform clinical decisions.
背景
体育活动和锻炼似乎能改善睡眠质量。然而，太极拳对成年人群睡眠质量的量化影响鲜有研究。我们进行了一项系统评价和荟萃分析，以评估太极拳对健康成年人及疾病人群睡眠质量的影响。
方法
检索截至2013年7月31日的Medline、Cochrane Central数据库及参考文献。纳入所有评估太极拳对成年人睡眠结局影响的英文研究。数据由两名审阅者提取并核实。提取的信息包括研究背景与设计、人群特征、干预类型与持续时间、结局、偏倚风险及主要结果。当至少3项试验报告了相同的睡眠结局时，采用随机效应模型荟萃分析评估治疗效果的大小。
结果
共纳入2004年至2012年间发表的11项研究（9项随机试验和2项非随机试验），共计994名受试者。除一项研究外，所有研究均报告了匹兹堡睡眠质量指数。9项随机试验报告，每周进行1.5至3小时、持续6至24周的太极拳练习能显著改善社区健康参与者及慢性病患者的睡眠质量（效应量为0.89；95%置信区间[CI]为0.28至1.50）。与各种对照组相比，太极拳组在包括身体机能、疼痛减轻和心理健康等健康结局方面有所改善。
局限性
研究具有异质性，部分试验缺乏方法学严谨性。
结论
太极拳能显著改善健康成年人及慢性疾病患者的睡眠质量，这表明太极拳可被视为治疗失眠的一种替代行为疗法。需要高质量、严格对照的随机试验来更好地为临床决策提供依据。
