mobile Pulmonary Rehabilitation - Determining the feasibility and acceptability of an adaptive mobile Pulmonary Rehabilitation (PR) programme

All participants will receive the mPR text message programme and can choose to also receive the mPR-app and/or mPR-sensor. The mPR text message programme includes receipt of anywhere between 2-10 text messages per week, depending on the modules they select (up to 3 modules), that are aimed at motivating people to exercise and supporting people with PR related health behaviours. Participants also receive a tailored exercise programme as part of this study, which is selected by their PR clinician at sign up. The exercise programme will contain exercises associated with stretching, cardiovascular or aerobic and strengthening. The mPR app programme includes PR related health information, a weekly exercise plan (same as the SMS exercise plan) selected by participants PR clinician at sign up, PR exercise videos (specifically created for this study), information on relaxation, a brief quality of life questionnaire and a built-in sit-to-stand test that participants can complete. Participants are asked to complete a sit to stand test and quality of life questionnaire every 2 weeks (if safe to do so). Outside of this request, participants are free to use the app as they wish. Participants who do not receive the app will still receive the exercise programme as part of the SMS component of the study. The mPR sensor programme includes participants being asked to wear a commercially available smart sensing watch as they wish, over the trial period. They will receive the intervention for 9 weeks. At the end of the programme all participants (including those that withdraw) will be asked to complete questions about their satisfaction with the programme, its perceived usefulness and usability, and perceived positive impacts, via a semi-structured telephone or online survey. Engagement with the intervention will be assessed at the end of the trial using self-reports and system-recorded measures including SMS responses, sensor data, and app data. Change in exercise capacity and health-related quality of life will also measure where there is available data. In addition, participants will consent to the research team obtaining their healthcare utilisation data including emergency department (ED) visits and hospitalisations (number and duration) during the study period from their health records.
