Objectives To investigate the effectiveness of a 6-month Liuzijue qigong (LQG) program in promoting physical and psychosocial function in individuals with chronic obstructive pulmonary disease (COPD).
Design Single-blind, randomized controlled trial.
Setting Seven hospital respiratory care centers in Beijing.
Participants Individuals with COPD (N = 126; mean age 71.1 ± 2.7, range 65–85).
Methods Participants were randomly assigned to one of two groups: LQG (n = 63) and control (n = 63). Subjects in the LQG group received a LQG program consisting of four 45-minute sessions each week and daily walking for 30 minutes for 6 months. Control subjects walked daily for 30 minutes. Data collection was performed at baseline, at 6 weeks, and at 6 months. Primary outcomes involved functional capacity, and secondary outcomes involved quality of life.
Results The LQG group had greater improvements in the 6-minute walk test (P = .02); specific airway conductance (P = .02); monitored functional task evaluation (P = .04); Medical Outcomes Study 36-item Short-Form Health Survey (SF-36; general health (P < .001), mental health (P = .03)); Chronic Respiratory Questionnaire (dyspnea (P = .05), emotion (P = .05), and mastery (P = .04) at 6-month follow-up. After 6 months, the control group had significant improvement only on the SF-36 mental health (P = .02).
Conclusion LQG promoted functional capacity and quality of life in older adults with COPD at 6 months and is a good alternative home exercise program for older adults in the rehabilitation of COPD.
