Objectives. To assess the current clinical evidence of Tai Chi for essential hypertension (EH). Search Strategy. 7 electronic databases were searched until 20 April, 2013. Inclusion Criteria. We included randomized trials testing Tai Chi versus routine care or antihypertensive drugs. Trials testing Tai Chi combined with antihypertensive drugs versus antihypertensive drugs were also included. Data Extraction and Analyses. Study selection, data extraction, quality assessment, and data analyses were conducted according to the Cochrane standards. Results. 18 trials were included. Methodological quality of the trials was low. 14 trials compared Tai Chi with routine care. 1 trial compared Tai Chi with antihypertensive drugs. Meta-analysis all showed significant effect of TaiChi in lowering blood pressure (BP). 3 trials compared Tai Chi plus antihypertensive drugs with antihypertensive drugs. Positive results in BP were found in the other 2 combination groups. Most of the trials did not report adverse events, and the safety of Tai Chi is still uncertain. Conclusions. There is some encouraging evidence of Tai Chi for EH. However, due to poor methodological quality of included studies, the evidence remains weak. Rigorously designed trials are needed to confirm the evidence.
目的。评估太极拳治疗原发性高血压（EH）的现有临床证据。
检索策略。截至 2013 年 4 月 20 日，检索了 7 个电子数据库。
纳入标准。我们纳入了测试太极拳与常规护理或抗高血压药物相比的随机试验。还包括测试太极拳联合抗高血压药物与抗高血压药物相比的试验。
数据提取和分析。根据 Cochrane 标准进行研究选择、数据提取、质量评估和数据分析。
结果。纳入了 18 项试验。试验的方法学质量较低。14 项试验比较了太极拳与常规护理。1 项试验比较了太极拳与抗高血压药物。荟萃分析均表明太极拳在降低血压（BP）方面有显著效果。3 项试验比较了太极拳加抗高血压药物与抗高血压药物。在另外 2 个联合组中也发现了 BP 的阳性结果。大多数试验没有报告不良事件，太极拳的安全性仍不确定。
结论。太极拳治疗 EH 的证据有些令人鼓舞。然而，由于纳入研究的方法学质量较差，证据仍然较弱。需要进行严格设计的试验来证实这一证据。
