Chronic obstructive pulmonary disease is a chronic inflammatory lung disease that causes obstructed airflow from the lung, characterized by chronic cough, dyspnea, and sputum production, which often misunderstood as aging or catching a cold. These symptoms may be progressive over time. To provide better disease management and early detecting, pulmonary rehabilitation is now considered a fundamental component of the integrated disease management of this population. However, few studies have evaluated the beneficial outcomes in patients referred to pulmonary rehabilitation. Therefore, the purpose of this study is to investigate the clinical outcomes in patients referred to pulmonary rehabilitation in National Taiwan University Hospital.

RECRUITINGFunctional exercise capacity using the six-minute walk test
The six-minute walk test is commonly performed to evaluate functional exercise capacity. The six-minute walk test was performed according to the guidelines, and the distance walked in the test presented as functional exercise capacity.
Time frame: The six-minute walk test needs six minute to complete the test
Muscle strength: hand grip
Hand grip strength is performed by using hand dynamometer
Time frame: Hand grip of both hands need about three minutes to complete
Lung hygiene
Lung hygiene is evaluated by the frequency of acute exacerbation
Time frame: Lung hygiene is evaluated as the frequency of acute exacerbation in the the past one year
Home-based physical activity
All subjects were encouraged to increase their daily physical activity and recorded the amount of physical activity on patient-self-record training log.
Time frame: Record the home-based physical activities everyday that the subjects have in the past one week that lasting for one year.
Muscle strength: leg press
Maximum leg press is performed by using seated leg press machine
Time frame: Maximum leg press measurement needs about four minutes to complete
Heart rate
Heart rate is measured at rest, during hospital-based physical training.
Time frame: Hospital-based physical training takes 30 minutes, once a week, and it also takes 30 min to measure continuously
Blood pressure
systolic and diastolic pressure are measured at rest, during hospital-based physical training.
Time frame: Hospital-based physical training takes 30 minutes, once a week, and it also takes 30 min to measure continuously
Perceived dyspnea
Rating of perceived dyspnea is measured by using Borg scale at rest, during hospital-based physical training, and home-based physical activity. The most widely used tool is the "Borg scale", with rating ranges from 0 (nothing at all) to 10 (extremely dyspnea).
Time frame: It takes less than one minute to evaluate perceived dyspnea.
Oxygen saturation
Oxygen saturation is continuously monitored by pulse oximetry throughout Hospital-based physical training.
Time frame: Hospital-based physical training takes 30 minutes, once a week, and it also takes 30 min to measure continuously
