Brief summary
The aim of this study is to investigate the effects of a walking program on exercise capacity and quality of life in patient with COPD. Method: Patients with COPD were randomly assigned to pedometer group (PG) or control group (CON). Subjects in PG walked to target steps daily with pedometer for 6 weeks. Before and after the program, the following measurements were performed: pulmonary function test (PFT), daily steps, Six-Minute Walk Test (6MWT), COPD Assessment Test (CAT), and quality of life questionnaire (SF-12).
Detailed description
Patients with chronic obstructive pulmonary disease (COPD) are suffered from impaired pulmonary function and dyspnea which result to limited level of physical activity, and impaired quality of life. Exercise and regular physical activity have been proven to break the vicious circle. The aim of this study is to investigate the effects of a walking program on exercise capacity and quality of life in patient with COPD. Method: Patients with COPD were randomly assigned to pedometer group (PG) or control group (CON). Subjects in PG walked to target steps daily with pedometer for 6 weeks. Before and after the program, the pulmonary function was assessed by spiromtery test. The exercise capacity were assessed by six-minute walking test, the physical activity level was assessed by daily steps, The quality of life was assessed by COPD Assessment Test (CAT), and quality of life questionnaire (SF-12). .

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| tidal volume | week 0 | the amount of air that moves in or out of the lungs with each respiratory cycle. It is measured by spirometers. |
| Short-form 12 questionnaire (SF-12) | week 0 | The SF-12 is a quality of life questionnaire. The scores range from 0 (worst conceivable QOL) to 100 (best conceivable QOL) |
| 6 minute walking test | week 0 | walking distance |
| daily steps | week0 | the number of total walking steps per day which is measured by pedometer. |
