This study focused on "the effectiveness of a 3-month Tai chi
Qigong (TCQ) program in promoting the psychosocial functional health of
clients with chronic obstructive pulmonary disease (COPD) in Hong Kong. . . . two hundred and six COPD clients were randomly assigned into
three groups, namely, TCQ group, exercise group, and control group.
Subjects in the TCQ group received a TCQ program, consisting of two
60-min sessions each week for 3 months. Subjects in the exercise group
were taught to practice breathing techniques combined with walking as an
exercise. Subjects in the control group received their usual care. Data
collections were performed at baseline, on the sixth week and on the
third month."
The TCQ group showed greater improvements in the symptom and activity domains; however, there were no differences detected in perceived social support among the three groups. "Tai chi Qigong promoted health outcomes with respect to clients' perception of their respiratory symptoms. Moreover, TCQ decreased disturbances to their physical activities."
