Brief summary
The six-minute walk test (6MWT) is a well established field exercise test to assess the functional exercise capacity in chronic obstructive pulmonary disease (COPD). The objective of this study is to assess the impact of walking behind the patient on 6MWT distance in patients with COPD.
Detailed description
In a single-center, randomized crossover study, the investigators aim to elucidate whether there is a difference in the 6MWT distance when the assessor walks behind the patient compared to the patient walking alone. Patients with COPD referred for pulmonary rehabilitation will be invited to perform an accompanied 6MWT (assessor walks behind the patient) and unaccompanied 6MWT (assessor does not walk behind the patient) in random order. The tests will be performed at the end of a pulmonary rehabilitation program, after patients are familiarised with the 6MWT testing procedure and learning effects can be excluded.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Exercise capacity | During pulmonary rehabilitation, approximately 14 days | Difference in six minute walk test distance between the two experimental conditions (in meter) |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Six minute walk test | During pulmonary rehabilitation, approximately 14 days | Difference in patient reported perception during the two different walking tests assessed with a self-administered questionnaire. The questionnaire contains 5 questions with five response categories: 1=not at all; 2 = somewhat; 3=modestly; 4=strongly; 5= very strongly |
Other
| Measure | Time frame | Description |
|---|---|---|
| Oxygen saturation | During pulmonary rehabilitation, approximately 14 days | Difference in oxygen saturation profiles between the two experimental conditions |
