title: Evaluation of the sustaining effects of Tai Chi Qigong in the sixth month in promoting psychosocial health in COPD patients: a single-blind, randomized controlled trial.
abstract: OBJECTIVE
  To evaluate the sustaining effects of Tai Chi Qigong (TCQ) in improving the psychosocial health in chronic obstructive pulmonary disease (COPD) patients in the sixth month.
  
  
  BACKGROUND
  COPD affects both physical and emotional aspects of life. Measures to minimize patients' suffering need to be implemented.
  
  
  METHODS
  206 COPD patients were randomly assigned into three groups: TCQ group, exercise group, and control group. The TCQ group completed a three-month TCQ program, the exercise group practiced breathing and walking exercise, and the control group received usual care.
  
  
  RESULTS
  Significant group-by-time interactions in quality of life (QOL) using St. George's respiratory questionnaire (P = 0.002) and the perceived social support from friends using multidimensional scale of perceived social support (P = 0.04) were noted. Improvements were observed in the TCQ group only.
  
  
  CONCLUSIONS
  TCQ has sustaining effects in improving psychosocial health; it is also a useful and appropriate exercise for COPD patients.
