Chronic Obstructive Pulmonary Disease (COPD), characterized by persistent airflow limitation in the respiratory airways, is a chronic condition that affects millions of people worldwide. ReHub enables healthcare professionals to design therapeutic exercise programs for the treatment of COPD patients, as well as to analyze and monitor patient rehabilitation through the information and feedback provided via the platform. The main objective of the study is to evaluate the satisfaction and usability of the ReHub platform (for respiratory rehabilitation) among COPD patients and healthcare professionals. This is a single-center satisfaction and usability study on the usage and experience of the ReHub platform (for respiratory rehabilitation).
