Effectiveness of a Physical ACtivity Coaching Intervention Using E-Health for COPD Patients in Pulmonary Rehabilitation

This randomized controlled trial aims to evaluate the efficacy of a physical activity coaching intervention - delivered through an eHealth platform, both during and after pulmonary rehabilitation - to enhance physical activity levels and health-related outcomes in patients with Chronic Obstructive Pulmonary Disease (COPD). All participants will attend the pulmonary rehabilitation program for 10 weeks. At week 5 of the rehabilitation program, the experimental group will receive a physical activity coaching intervention, which will continue for 6 months following its completion. This intervention will include an eHealth platform divided into two applications (a mobile app for patients and a web app for researchers/healthcare professionals). Goal setting and progression according to patients' performance and willingness to increase will occur every week, through phone calls. Barriers to physical activity and strategies to overcome them will be identified between the patient and researcher, during the goal-setting moments. Notifications about PA goals achievement and incentives will be sent to patients during the intervention. The assessment moments will be conducted at the beginning, midway, and end of the pulmonary rehabilitation program, as well as 3- and 6 months after its conclusion.
