Yoga is adjunctively utilized outside the United States in the
treatment of a variety of diseases, including chronic obstructive
pulmonary disease (COPD), but there are no studies assessing its
adjunctive efficacy in the United States. We prospectively evaluated
the effects of yoga training on the quality of life (QOL) and the
parameters of lung function in patients with COPD. Thirty-three
patients with documented COPD, per Global Initiative for Obstructive
Lung Disease criteria, were recruited. All patients received standard
COPD care. The QOL was assessed by the St. George Respiratory
questionnaire. Standard spirometry and maximum inspiratory (maximal
inspiratory pressure) and expiratory pressure (maximal expiratory
pressure) were measured. Patients were taught selected yoga exercises
including breathing exercises, meditation, and yoga postures for 1
hour, thrice a week for 6 weeks by a certified yoga therapist. The
quality of life and lung function were again assessed at the end of 6
weeks. Twenty-two patients completed the study. Differences in preyoga
versus postyoga scores were evaluated using paired t-tests.
Statistically significant improvements (P < 0.05) were observed for
the St. George Respiratory questionnaire [95% confidence interval (CI)
43.13-58.47], vital capacity (95% CI 2.53-7.65), maximal inspiratory
pressure (95% CI 6.62-23.64), and maximal expiratory pressure (95% CI
1.63-13.81). Yoga when practiced by patients with COPD results in
improvement in the QOL and lung function on a short-term basis.
Additional research is needed to confirm these findings in a
randomized controlled trial and in the longer term.
