Qigong can reduce symptoms of fatigue and depression in patients with chronic fatigue syndrome (CFS)-like illness, a Hong Kong study has found. One hundred and thirty-seven participants who met the diagnostic criteria for CFS-like illness were randomly assigned to either an intervention group or a waitlist control group. Participants in the intervention group received 10 sessions of qigong training twice a week for five consecutive weeks, followed by home-based practice for 12 weeks. At the end of the training period, the results showed that total fatigue score, physical fatigue score and depression score were significantly improved and mental fatigue score was marginally significantly improved in the qigong group compared to controls. Anxiety score was not significantly improved in the qigong group.
