Physical Function in Patients With Chronic Obstructive Pulmonary Disease

Study Overview
=================
Brief Summary
-----------------
The aims of the study are to examine the responsiveness of, and the correlation between field walk tests and physical performance test in patients with chronic obstructive pulmonary disease (COPD) after participating in pulmonary rehabilitation.

Detailed Description
-----------------
Patients with COPD who are participating at pulmonary rehabilitation (PR) at Haukeland University Hospital will be asked and consecutive enrolled to the study. Before and after PR the six-minute walk test, incremental- and endurance shuttle walk test, 30 sec sit-to-stand test and stair test will be used to evaluate change in physical capacity and -performance.
