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.
Physician diagnosis of chronic respiratory disease (e.g., Chronic Obstructive Pulmonary Disease, Interstitial Lung Disease, Asthma).
Male and female patients ≥18 years of age.
Able to perform at least 5 repetitions in the 1-min sit-to-stand test without use of upper extremities.
Access to a portable pulse oximeter at home to measure heart rate and oxygen saturation.
Lower limb surgery in the preceding 3 months.
Medically unstable to perform exercise tests (e.g., no exacerbation in the preceding two weeks).
Predominant neurological or musculoskeletal limitations to completing sit-to-stand.
At risk of falling during sit-to-stand due to impaired balance, as indicated in their clinical record, and/or PR assessment.
