Qigong and Tai Chi on Human Health: An Overview of Systematic Reviews

Qigong and Tai chi are traditional methods of physical and mental training and exercises in East Asia. Their health-promoting effects against various diseases have been studied for a long time, and they have been the subject of many clinical trials and systematic reviews (SRs). The present study aimed to comprehensively evaluate all published SRs on Qigong and Tai chi and to summarize the supporting evidence. The following databases were searched: PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure, Research Information Sharing Service, and Korean Studies Information Service System. The selection and extraction processes were performed by two independent reviewers, and a qualitative synthesis was conducted. There were 58 SRs of randomized controlled trials on Qigong and Tai chi. There have been many studies on patients with cardiovascular diseases and different cancers, and a number of other studies in which mobility, quality of life, blood lipids, and blood pressure were outcome measurements. Thus, Qigong and Tai chi for various diseases and medical conditions have been accumulated. Based on current evidence, the number of publications of Qigong and Tai chi-related articles showed an increasing trend, and most of them were performed in China. Qigong and Tai chi have shown beneficial effects in different age groups and health conditions, including decreasing blood lipid level, reducing blood pressure, facilitating mobility, preventing falls, and improving overall quality of life.
