Clinical Trial Summary

The aim of this observational study is to translate the principle of individualised exercise prescription into the evaluation of daily absolute and relative intensity physical activity. The main questions this study aims to answer are: - Phase 1: What does physical activity (intensity) mean to people with COPD? - Phase 2: Are there differences between time spent in absolute and relative physical activity for people with COPD? Phase 1 Participants will take part in semi-structured interview (30-45 minutes) about living with COPD and perceptions of physical activity and how they perceive intensity. This will also include photovoice and photo-elicitation. Demographic information will be recorded and participants will also complete several respiratory symptom questionnaires. Phase 2: Participants will take part in physical activity testing before and after pulmonary rehabilitation while wearing physical activity monitors. Demographic information will be recorded and participants will also complete several respiratory symptom and physical activity questionnaires. Participants will also wear the physical activity monitors for 8 days after the pre-testing sessions and after their final pulmonary rehabilitation class. Sub-study: Participants will be asked to take images of barriers during physical activity, facilitators during physical activity, feelings during physical activity and types of physical activity they take part in for 8 days after their final pulmonary rehabilitation class. Participants will then take part in a semi-structured interview about the images their have taken while doing physical activity.


Description:

Physical activity (PA) helps prevent and manage non-communicable diseases such as chronic obstructive pulmonary disease (COPD). Pulmonary rehabilitation (PR) has been shown to benefit people living with COPD by reducing breathlessness, increasing muscle strength, and improving the management of exacerbations. However, the improvement in PA in individuals with COPD remains inconsistent following PR. Despite the personalised nature of PA prescription during PR, the evaluation of free-living PA data has been limited to a 'one size fits all' approach using absolute intensity categories. Reduced exercise tolerance can result in PA being perceived at a high intensity relative to a person's exercise capacity, despite the absolute intensity being low. Exploring both the relative and absolute intensity of PA could offer additional insights and clinical relevance for the evaluation of physical activity in COPD populations. The aim of this research is to translate the principle of individualised exercise prescription into the evaluation of daily absolute and relative intensity PA in a user-friendly format for PR teams and service users. Phase 1 objective: To explore what PA means to people with COPD in the context of relative intensity and pulmonary rehabilitation. Phase 2 objective: To examine the differences between time spent in physical activity intensity expressed in absolute and relative terms for people with COPD. Phase 1: Semi-structured interviews will take place where participants will discuss their COPD and their perceptions of physical activity and relative intensity. The interviews will be in person (Biomedical research centre, Leicester) or over the phone/video call. The participants will complete several questionnaires about respiratory symptoms. Before taking part in the interviews, participants will also be asked to take pictures, using a camera provided, of when they are doing physical activity. This will be for a 7 day period before the interview. Phase 2: Participants will take part in exercise testing and complete questionnaires pre and post pulmonary rehabilitation while wearing activity and gait monitors. Participants will also be asked to wear the activity monitors for 8-days after the pre-testing sessions and 8-days after their last pulmonary rehabilitation class. Following their last pulmonary rehabilitation class, 20 participants will be asked to take photographs during the period they are wearing accelerometers and motion sensors. When the participants return the devices, they will take part in an interview to discuss the images they have taken while taking part in physical activity.

Type Measure Description Time frame Safety issue
Primary Phase 1 - Semi-structured Interviews Semi-structured interview with individuals with COPD 30-45 minutes
Primary Phase 2 - Differences between time spent in PA intensity expressed in absolute and relative intensity. Differences between time spent in PA intensity expressed in absolute and relative using activity monitors (wrist and waist) for eight days before and after the PR programme. 8 days
Secondary Phase 1 - Medical Research Council (MRC) Dyspnoea Scale Medical Research Council (MRC) Dyspnoea Scale Minimum value: 1 Maximum value: 5 The higher the score, the worse the outcome (breathlessness). 2 minutes
Secondary Phase 1 - COPD Assessment Test (CAT) COPD Assessment Test (CAT) 5 minutes
Secondary Phase 1 - Chronic Respiratory Questionnaire (CRQ-SR) Chronic Respiratory Questionnaire (CRQ-SR) 5 minutes
Secondary Phase 1 - Photovoice and photo-elicitation Photovoice is a qualitative research method that focuses on participants identifying and addressing important topics that matter to them through photography. This will gain greater insight from the participants about their experiences of participating in PA. Participant-generated images will be used to inform the photo-elicitation aspect of the interview to enable participants to capture in real time, more graphically illustrate their experiences and perceptions of different types of PA. 7 days
