Functional and Psychosocial Effects of Health Qigong in Patients with COPD
April 28, 2011
The initial gain from a Pulmonary Rehabilitation Program (PRP) among patients
with chronic obstructive pulmonary disease (COPD) begins to fade away 6 months
after the completion of a rehabilitation program. One possible reason may be due
to the poor compliance of the patients to the existing forms of home exercise
program (e.g., walking, weight training activities, etc.).
Researchers from the Hong Kong Polytechnic
University tested the efficacy of Health Qigong (HQG), a traditional Chinese
exercise, as an adjunct home exercise program in optimizing the gains obtained
from PRP until 6 months after discharge.
This was a randomized controlled trial on a
mind-body exercise intervention. Eighty patients with COPD receiving
conventional PRP pulmonary rehabilitation program were randomized to the Qigong
intervention group (n?=?40) and control group (n?=?40).
Assessments were undertaken by blinded
assessors at baseline, discharge from training, and follow-up at 3 and 6 months.
Primary outcomes involved functional capacity scales and secondary outcomes
involved quality-of-life scales. Results: Intention-to-treat analysis identified
trends of improvement in all outcome measures in the Health Qigong group,
whereas lesser improvement and trends of deteriorations were identified in the
control group. Ancillary analysis using a per-protocol method, however,
identified significantly better improvements in functional capacity measures
among the Health Qigong group at the 6-month follow-up.
Conclusions: This RCT provided some evidence
to support the positive effect of Health Qigong as an adjunct home exercise for
rehabilitation among people with COPD and to support further related research.
