Summary

Investigators will perform this study to validate shuttle walking tests in korean patients with chronic obstructive pulmonary disease. This study will be performed as multi-center prospective observational correlation study in ulsan university hospital and asan medical center. 36 participants will perform the exercise stress test with cycle, 6 minutes walking test and shuttle walking test. Investigators will analyze correlation 6 minutes walking test and shuttle walking test with exercise stress test.

Detailed description

Investigators will perform this study to validate shuttle walking tests in korean patients with chronic obstructive pulmonary disease. This study will be performed as multi-center prospective observational correlation study in ulsan university hospital and asan medical center. 18 patients will be enrolled in each hospital. When then visit, patients will perform questionnaire and laboratory study for baseline characteristics. After that, patients select memo, in which order for the exercise stress test with cycle, 6 minutes walking test and shuttle walking test will be written. Along that order, patients will perform each study at every two day in a week. Investigators will analyze correlation 6 minutes walking test and shuttle walking test with exercise stress test. To analyze reliability in shuttle walking test, patients will shuttle walking test in two times. Researchers will analyze correlation between them.

Conditions

• Chronic Obstructive Pulmonary Disease

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Shuttle walking test	Patients will be required to walk around a 10-m course marked by cones placed 9 m apart, thus allowing 0.5 m for turning at each end. Walking speed will be regulated by prerecorded signals on a compact disc or MP3 file. Patients will increase walking speed at every minute. patients can stop this study, when they can not maintain their speeds due to dyspnea
DIAGNOSTIC_TEST	Exercise stress test	Exercise stress test will be performed with cycle. When patients perform this study, they will gradually increase the velocity. Investigators will measure electrocardiography, vital sign, oxygen saturation, oxygen uptake, minute ventilation and fatigue.
DIAGNOSTIC_TEST	6 minutes walking test	When participants perform 6 minutes walking test, patients will walk around the tract during 6 minutes. They can their walking speed according to condition and symptom. Investigators records walking distance, pulse rate, oxygen saturation and Borg scale
