Brief summary: In patients with Chronic Obstructive Pulmonary Disease (COPD) daily physical activity is reduced compared to healthy age-matched individuals. Reduced levels of physical activity in patients with COPD are associated with increased risk for exacerbations, hospital admissions and mortality.

Pulmonary rehabilitation (PR) constitutes standard care for patients with COPD as it improves exercise capacity, quality of life and reduces the risk for exacerbation and hospitalisation. Participation in PR, however, does not necessarily translate into improved daily physical activity levels. It is currently uncertain whether addition of physical activity promotion strategies to standard PR programs induces an improvement in daily physical activity along with exercise capacity and quality of life compared to pulmonary rehabilitation alone.

Physical activity (PA) is a complex health behaviour that is modified by behavioural change interventions. PA promotion programs through the use of wearable monitors (i.e. pedometers, accelerometers) with goal setting and feedback, have shown to increase daily physical activity, but not exercise capacity or quality of life in COPD patients. Therefore, combination of both PR and PA promotion strategies is necessary to translate PR-induced improvements in functional capacity into improved daily physical activity level. The investigators propose to perform a feasibility study assessing patient adherence to PA promotion incorporated into a standard PR program. To enhance adherence to the PA promotion strategy, Cognitive Behavioural Modification Strategies (CBM) will be provided to patients undertaking PR. CBM strategies facilitate the goals of PR as they address several behavioural barriers including anxiety, depression and physical inactivity, and constitutes an important component in the management of COPD to improve engagement with PR and promote a physically active lifestyle. The investigators will divide patients into two programs: one including PR, PA promotion and CBM and the other comprising standard PR and CBM provision. The investigators will compare patients' adherence (16 sessions of PR) to both programs.

Detailed description: Chronic Obstructive Pulmonary Disease (COPD) is a debilitating and progressive disease, primarily affecting the respiratory system. In many patients, it also has adverse extra-pulmonary effects, such as skeletal muscle dysfunction and weakness (Maltais, et al. 2014). Pulmonary and skeletal muscle metabolic abnormalities enhance the ventilatory requirement during exercise, resulting in exercise-associated symptoms such as breathlessness and leg discomfort. These symptoms make every day physical activity an unpleasant experience, which many patients try to avoid (Troosters, et al. 2013). Physical activity levels are therefore remarkably lower in COPD patients than healthy age-matched individuals, presenting a major predictor of exacerbations, hospitalisations and mortality and in these patients (Pitta et al. 2005) \& (Garcia-Aymerich et al. 2006).

Implementation of exercise training as part of Pulmonary Rehabilitation aims to reverse the systemic consequences of COPD, in particular skeletal muscle dysfunction and weakness (Troosters, et al. 2013) . Currently pulmonary rehabilitation programs have shown substantial improvements in exercise capacity; however, these findings have not consistently progressed into improvements in daily levels of physical activity (Watz et al. 2014). One reason for this may link to physical activity in COPD being a complex health behaviour (Troosters, et al. 2013).

Recently, physical activity coaching, including weekly targets and feedback, has shown to be effective in patients with COPD in terms of improving daily steps over a period of three months (Lahham et al. 2016). Accordingly, activity coaching may be added to standard pulmonary rehabilitation to facilitate the rehabilitation-induced improvements in exercise capacity to progress into improvements in physical activity (Lahham et al. 2016).

Alongside the physical barriers influencing daily physical activity, the distressing nature of COPD has a significant impact on patients' psychological well-being. Major focusing points for COPD patients are the sense of feeling unwell, the inability to perform everyday activities and the emotional consequences of the condition. These symptoms can promote anxiety and depression, which are prevalent in patients with COPD, are associated with poorer treatment outcomes, and reduced survival (Ng, T-P et al. 2007).

Cognitive Behavioural Modification (CBM) strategies constitute an intervention that focuses on understanding how experiences are interpreted. It provides an understanding of the interaction between thoughts, mood, behaviour and physical sensations, which are intrinsically linked \[8\]. Techniques used for anxiety include education on anxiety and COPD, planning/pacing, distraction techniques, breathing control, relaxation and managing worry. These techniques help to break the vicious cycle of anxiety and can reduce patients' distress (Heslop \& Foley. 2009).

Similar techniques for patients suffering mainly from depression include education about depression and physical inactivity and planning and recording activities each day, while rating these for achievement or pleasure. These techniques help to break patient inactivity, which can lead to low mood and poor physical condition. A key treatment for depression can involve encouragement to increase activities within the patients' physical capabilities. A study found clinical and statistically significant improvements in anxiety and depression scores and a statistically significant reduction in hospital admissions following CBM. CBM is therefore an important approach to incorporate into COPD management to improve engagement with both pulmonary rehabilitation and the physical activity promotion programme Heslop \& Foley. 2009.

The efficacy of incorporating a physical activity promotion program to standard care pulmonary rehabilitation along with CBM strategies is still unknown. Accordingly, it is proposed to study patient compliance with the physical activity promotion programme comprising weekly goals in terms of daily step counts measured by a commercially available step counter. Compliance to the intervention is defined as at least 4 days per week (\> 8 hours/day) with valid step count data (\>70 steps/day) ensuring that patients use the step counter on a daily basis. Over the 8-week program patients should have a minimum of 6 weeks (75%) compliance with the physical activity intervention. If patients adhere adequately to this programme, a randomised controlled trial will be designed to study the long-term effects of adding physical activity promotion to Pulmonary Rehabilitation (including exercise training, education, physical activity promotion and behavioural modification strategies) on the risk for COPD exacerbations and hospitalisations.
