Clinical Trial Summary

The goal of this validation study is to provide further evidence of the metrological properties of the 6-minute stepper test in individuals with chronic obstructive pulmonary disease (COPD) or interstitial lung disease (ILD).

The main questions it aims to answer are:

1. Is the 6-minute stepper test valid when compared to the 6-minute walk test and a maximal cardiopulmonary cycling test?

2. Does the 6-minute stepper test give the same results when conducted through direct (i.e., therapist in person) and remote (i.e., videoconferencing) monitoring?

3. Is the 6-minute stepper test safe when conducted at the home of the individual with direct (i.e., therapist in person) or remote (i.e., videoconferencing) monitoring?

Participants will:

• Conduct the 6-minute stepper test (several trials on separate days)

• Conduct the 6-minute walk test (1 trial on 1 day)

• Conduct a maximal cardiopulmonary test on a cycle ergometer (1 trial on 1 day)

• Participate in a semi-structured interview to provide their feedback with regards to the 6-minute stepper test

Eligibility

Inclusion Criteria:

• Adult = 40 years old

• Diagnosis of chronic obstructive pulmonary disease (GOLDa 2 to 4) or of interstitial lung disease (> 6 months)

• Clinically stable for = 4 weeks

Exclusion Criteria:

• Interstitial lung disease associated with connective tissue disease and sarcoidosis (often accompanied with multisystemic effects)

• Unstable or severe cardiac condition

• Invalidating rheumatologic or neurologic condition

• Weight exceeding maximal limits of exercise equipment (e.g., 130 kg for the stepper)

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Concurrent validity	Assessed using paired sample t-tests (or Wilcoxon signed-rank tests) to verify whether peak cardiorespiratory (e.g., oxygen consumption, minute ventilation, heart rate, etc.) and symptomology (i.e., dyspnea and leg fatigue) values obtained during the 6-minute stepper test are comparable to the maximal cardiopulmonary test and the 6-minute walk test	Study 1 - Two 3-hour laboratory visits (separated by 6 to 18 days)
Primary	Strength of association between peak cardiorespiratory and symptomology values	Pearson's correlation coefficients (r) will be calculated between the number of steps taken during the 6-minute stepper test and peak oxygen consumption and heart rate reached during all three tests	Study 1 - Two 3-hour laboratory visits (separated by 6 to 18 days)
Primary	Agreement	Assessed with Bland-Altman plots and 95% limits of agreement (mean difference ± 1.96 standard deviation of the difference) between peak cardiorespiratory and symptomology values reached during the 6-minute stepper test and those reached during the maximal cardiopulmonary test and the 6-minute walk test	Study 1 - Two 3-hour laboratory visits (separated by 6 to 18 days)
Primary	Test-restest reliability	Reliability (trial 2 versus 3 = directly versus remotely monitored) will be assessed using paired sample t-tests (or Wilcoxon signed-rank tests), Bland-Altman plots (with 95% limits of agreement), and intraclass correlations	Study 2 - Trial 2 and 3 (separated by 2 to 5 days)
Secondary	Adverse events	All minor and serious adverse events, for all trials, will be reported	Through study completion, an average of 2 years
Secondary	Level of comfort during test and perception of safety (qualitative)	Assessed with thematic content analysis of semi-structured interviews (voice-recorded and transcribed)	Study 2 - Trial 3 (semi-structured interview of 20 to 30 minutes following the completion of the last trial of the 6MST)
