via Violet Li at the Tai Chi Examiner:
Sieving through peer-reviewed English-language journal articles published between 1993 and 2007, a team of researchers reviewed results from 67 unique studies testing the benefits of Qigong and/or Taiji using randomized controlled trials (RCTs). Their conclusion:
“… research in RCTs has demonstrated consistent, significant results for a number of health benefits: positive effects on bone health, favorable cardiovascular and/or pulmonary outcomes, positive physical function improvements, significant improvement of fall prevention, improving quality of life for healthy or chronically ill patients, better pain management for arthritis and fibromyalgia patients, decreasing in anxiety, and immune system betterment. There is evidence to recognize the similarity and equivalence of Qigong and Tai Chi, especially in the simplified Tai Chi forms. Additionally, the research asserts that it does not matter whether Tai Chi or Qigong was used as the intervention method; the health benefits are similar.”
