Tai Chi for chronic obstructive pulmonary disease (COPD)

Area of Science:

• Integrative and Complementary Medicine
• Respiratory Medicine
• Gerontology

Background:

• Tai Chi, an ancient Chinese exercise, involves slow, rhythmic movements emphasizing mind-body connection for energy flow, believed to promote homeostasis and longevity.
• While beneficial for balance and strength in the elderly, Tai Chi's impact on chronic obstructive pulmonary disease (COPD) symptoms like dyspnoea, exercise capacity, and psychosocial status is not well-established.

Purpose of the Study:

• To evaluate Tai Chi's effectiveness in alleviating dyspnoea and enhancing exercise capacity in COPD patients.
• To assess Tai Chi's influence on the physiological and psychosocial functions of individuals diagnosed with COPD.

Main Methods:

• A systematic literature search was conducted across multiple databases (Cochrane, MEDLINE, EMBASE, CINAHL, AMED, PsycINFO, Chinese databases) up to September 2015.
• Randomized controlled trials (RCTs) comparing Tai Chi (alone or with other interventions) against control groups (usual care or identical interventions) in COPD patients were included.
• Data extraction and risk of bias assessment were performed by two independent reviewers, with data synthesized using RevMan software.

Main Results:

• Analysis of 12 RCTs involving 811 participants indicated that Tai Chi significantly improved the six-minute walk distance and pulmonary function (FEV1) compared to usual care.
• The impact of Tai Chi on reducing dyspnoea and improving quality of life remains inconclusive, with insufficient data on its effects on maximal exercise capacity, balance, and muscle strength.
• Combining Tai Chi with other interventions (breathing or general exercise) did not demonstrate superiority or additional benefits over the control interventions alone.

Conclusions:

• Tai Chi is a safe intervention for individuals with COPD, with no reported adverse events.
• Moderate-to-very low quality evidence suggests Tai Chi improves functional capacity and pulmonary function when compared to usual care.
• Further research is needed to determine optimal Tai Chi protocols and its specific benefits when used as an adjunct therapy for COPD.
