Summary:
Despite evidence on the psychometric properties of sit-to-stand (STS) tests in chronic respiratory disease (CRD) populations, most studies have been conducted face-to-face. Given the recent emphasis on virtual pulmonary rehabilitation (VPR), there is a need to identify reliable and valid exercise tests that can be delivered in home-based settings, either supervised remotely or self-administered by patients. A repeated-measures crossover design will be used to test the home-based administration of STS tests. The 30-second STS (30-s STS) and 1-minute STS (1-min STS) tests will be randomly administered across three test conditions (centre-based, remotely supervised, and self-administered). Data will summarize the feasibility of remotely supervised and self-administered STS tests and compare the performances of centre-based tests with remotely supervised and self-administered versions of STS tests in patients with CRD.

Primary Outcome Measures: 30 second Sit-to-Stand Test, The 30-s and 1-min STS tests are reliable, valid, and responsive tests for measuring functional exercise capacity in patients with lung disease. For the STS tests that are centre-based or supervised remotely, investigators will collect the total number of repetitions on the 30-s and 1-min STS tests, as well as the number and duration of rests within and between tests. Scores on the STS tests will be recorded using the data collection form., Over a 7 day period, outcome will be collected at three time points (e.g., once within each testing condition: centre-based, remote, and self-administered)|1 minute Sit-to-stand Test, The 30-s and 1-min STS tests are reliable, valid, and responsive tests for measuring functional exercise capacity in patients with lung disease. For the STS tests that are centre-based or supervised remotely, investigators will collect the total number of repetitions on the 30-s and 1-min STS tests, as well as the number and duration of rests within and between tests. Scores on the STS tests will be recorded using the data collection form., Over a 7 day period, outcome will be collected at three time points (e.g., once within each testing condition: centre-based, remote, and self-administered)
Secondary Outcome Measures: Oxygen Saturation (Sp02), Oxygen saturation (Sp02) will be measured using a finger pulse oximeter before and after the 30-s and 1-min STS. Self-monitoring using remote pulse oximetry has been shown to be feasible and accurate in CRD populations. The oximeter will provide a printout of values reflecting oxygen level, which will be transcribed to a data collection form. Patients will be asked to use their own pulse oximeter, and the make and model will be recorded by study staff., participants will be asked to record their oxygen saturation (Sp02) before and after the STS test (30 second and 1 minute) within each arm|Heart Rate, Heart rate will be measured using a finger pulse oximeter before and after the 30-s and 1-min STS tests. Self-monitoring using remote pulse oximetry has been shown to be feasible and accurate in chronic respiratory disease populations. The oximeter will provide a printout of values reflecting HR, which will be transcribed to a data collection form. Patients will be asked to use their own pulse oximeter, and the make and model will be recorded by study staff., Participants will be asked to record their heart rate before and after the STS test (30 second and 1 minute) within each arm|Modified Borg Scale, The Modified Borg Dyspnea scale is a self-reported measure of one's difficulty breathing upon exertion. The instrument provides a standard method for patients to select ratings of dyspnea on a scale based on descriptors that correspond to specific numbers. At the start and at the end of each STS test, subjects will rate their perceived rate of dyspnea ("difficulty breathing") using the modified Borg Scale., participants will be asked to record their data pre-and post STS test (30 second and 1 minute) within each arm
