Impact of Walking Behind the COPD Patient on 6MWD

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.

About this study

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.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Patients with a diagnosis of COPD according to GOLD II-IV (FEV1/FVC < 0.7, FEV1%Norm < 80%)

Exclusion criteria

  • Inability to perform a 6MWT when arriving at the clinic (e.g., lower limb joint surgery within preceding 3 months, unstable cardiac disease, predominant neurological limitations)
  • Inability to understand the instructions of the 6MWT, either of language or cognitive reasons

Treatment and study plan

6MWT - accompanied

Other

Assessor walks behind the patient

6MWT - not accompanied

Other

Assessor does not walk behind the patient

Primary outcomes

  1. Exercise capacity

    Time frame: During pulmonary rehabilitation, approximately 14 days

    Difference in six minute walk test distance between the two experimental conditions (in meter)

Secondary outcomes

  1. Six minute walk test

    Time frame: 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 outcomes

  1. Oxygen saturation

    Time frame: During pulmonary rehabilitation, approximately 14 days

    Difference in oxygen saturation profiles between the two experimental conditions
