The 5 Repetitions Sit-to-stand Test, Carried Out Remotely Via Videoconference, in Patients With COPD: Is There a Learning Effect?

The purpose of this clinical study is to determine if a learning effect exists when the 5STS is assessed remotely via videoconference in patients with COPD.

Pulmonary rehabilitation (PR) is an essential therapy for improving exercise tolerance and quality of life in patients with chronic respiratory disease. It is now available remotely thanks to advances in information and communication technologies. Pulmonary telerehabilitation facilitates care access for patients living far from specialized centers. It requires, for a complete and coherent transposition, to be able to evaluate the patients remotely in order to measure the evolution of their functional capacities and to ensure their follow-up. Among the tests already implemented at home and remotely via video-conference, the 5-repetition sit-to-stand test (5STS) is the most suitable. This test requires only a short time to perform, little space and no specific equipment. However, two major limits remain to be checked before being able to consider its remote and routine implementation. First of all, it is important to study its feasibility. Moreover, like other functional tests, it raises the question of a possible learning effect (LE). In the perspective of a current use of the 5STS remotely, it is therefore also essential to assess the existence of a potential LE which would condition the methods of administering the test and its interpretation.

Patients will be asked to perform several times the 5STS test, from their home through videoconference, on 3 occasions (day 1, 24h later and 1month later).

Reproducibility is objectified by the test-retest reliability between two trials of the same series (first and fifth trials of V1) and between two series (V1-V2; V2-V3; V1 -V3).
