Respiratory Muscle Exercise Training in COPD Patients

Study Overview
=================
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.

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.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Multi-respiratory muscle training<br>Patients will perform multi-repiratory muscle training programe for 12 weeks | Behavioral: Multi-respiratory muscle training<br>* 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.<br>|
