Brief Summary:
COPD patients often suffer from dyspnea and exercise intolerance which lower their quality of life.The aim of this proposed study is to examine the effectiveness of multi-respiratory muscle training on respiratory function of COPD patients.

Condition or disease Intervention/treatment Phase
COPD Behavioral: Multi-respiratory muscle training Not Applicable

Detailed Description:
The respiratory muscle training is an important part of pulmonary rehabilitation. Subjects will be recruited from the chest medicine clinic of a medical center in Northern Taiwan, randomly assigned to control and experimental groups by severity status for a 12-week muscle training intervention.The outcome measures will be performed to evaluate respiratory function, depression status and quality of life at baseline, 4, 8 and 12 weeks of training.

Arm Intervention/treatment
Experimental: Multi-respiratory muscle training
Patients will perform multi-repiratory muscle training programe for 12 weeks
Behavioral: Multi-respiratory muscle training
Patients will be taught the diaphragmatic breathing technique at the same time also will be instructed a four-item (including upper-arm weighted exercise, body side-bends, modified sit-ups, body crunching) multi-respiratory muscle training motions. To practice three times/day, three days a week lasting 12 weeks at home.

No Intervention: Diaphragmatic breathing
Patients will be taught diaphragmatic breathing technique routinely. To practice at home lasting 12 weeks

Primary Outcome Measures :
  1. PE max [ Time Frame: three months ]
    maximal strength of expiratory muscle

Secondary Outcome Measures :
  1. PI max [ Time Frame: three months ]
    maximal strength of inspiratory muscle

  2. 6MWT [ Time Frame: three months ]
    six-minute walking test

  3. MVV [ Time Frame: three months ]
    maximal voluntary volume

Other Outcome Measures:
  1. St. George's Respiratory Questionnaire [ Time Frame: three months ]
    Disease-Specific quality of life

  2. CES-D [ Time Frame: three months ]
    assessment of depressive status
