Effects of Qigong Exercise on Fatigue, Anxiety, and Depressive Symptoms of Patients with Chronic Fatigue Syndrome-Like Illness : A Randomized Controlled Trial

الملخص EN

Background.

Anxiety/depressive symptoms are common in patients with chronic fatigue syndrome- (CFS-) like illness.

Qigong as a modality of complementary and alternative therapy has been increasingly applied by patients with chronic illnesses, but little is known about the effect of Qigong on anxiety/depressive symptoms of the patients with CFS-like illness.

Purpose.

To investigate the effects of Qigong on fatigue, anxiety, and depressive symptoms in patients with CFS-illness.

Methods.

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 5 consecutive weeks, followed by home-based practice for 12 weeks.

Fatigue, anxiety, and depressive symptoms were assessed at baseline and postintervention.

Results.

Total fatigue score [F1,135=13.888, P<0.001], physical fatigue score [F1,135=20.852, P<0.001] and depression score [F1,135=9.918, P=0.002] were significantly improved and mental fatigue score [F1,135=3.902, P=0.050] was marginally significantly improved in the Qigong group compared to controls.

The anxiety score was not significantly improved in the Qigong group.

Conclusion.

Qigong may not only reduce the fatigue symptoms, but also has antidepressive effect for patients with CFS-like illness.
