The Effect of Qigong on Depressive and Anxiety Symptoms
June 27, 2013 -
A study published by Evidence-based
Complementary and Alternative Medicine in May 2013 evaluated clinical trial
evidence of the effectiveness of Qigong on depressive and anxiety symptoms.
Thirteen databases were searched from their respective
inception through December 2012. Relevant randomized controlled trials (RCTs)
were included. Effects of qigong across trials were pooled. Standardized mean
differences (SMDs) were calculated for the pooled effects. Heterogeneity was
assessed using the I (2) test. Study quality was evaluated using the Wayne
Twelve RCTs met the inclusion criteria. The results of
meta-analyses suggested a beneficial effect of qigong exercise on depressive
symptoms when compared to waiting-list controls or usual care only, group
newspaper reading, and walking or conventional exercise, which might be
comparable to that of cognitive-behavioral therapy. Available evidence did not
suggest a beneficial effect of qigong exercise on anxiety symptoms.
Conclusion: Qigong may be potentially beneficial for
management of depressive symptoms, but the results should be interpreted with
caution due to the limited number of RCTs and associated methodological
weaknesses. Further rigorously designed RCTs are warranted. .
