Description of intervention(s) / exposure
Home-based pulmonary rehabilitation program (8 weeks): Participants are prescribed an exercise program by an experienced physiotherapist based on the results of their initial walking test. The exercise program consists of endurance (walking) and strengthening exercises. Participants are encouraged to exercise for 30 minutes, 5 times per week (including weekends). Strengthening exercises are performed using equipment that is available in the household (e.g. sit to stand from a chair, use of water bottles as arm weights). To optimise safety and a full understanding of the exercise program, an initial home visit from the physiotherapist is arranged before the program launch. The home visit talks one hour and 30 minutes on average. This home visit session facilitates exercise goal setting and demonstrates exercises. The physiotherapist helps participants to choose strengthening exercise provided by the Better Living for COPD handbook according to their physical abilities and equipment available in their household. The physiotherapist then prescribe the strengthening exercise types, sets and repetitions for the participant and record them using the exercise diary provided. Assessment and correction of inhaler use is also carried out during the home visit. Weekly phone calls is then undertaken by the physiotherapist to review the exercise diary, perform self-management training and promote exercise progression. Each weekly phone calls takes approximately 20 to 30 minutes. Disease specific self-management training and exercise progression is achieved using the principles of motivational interviewing. The aims of this training are to advance disease knowledge, promote problem solving and facilitate health behaviour change. A physiotherapist trained in the use of motivational interviewing is performing the telephone calls. Discussions of exercise goals settings, exercise tracking and recognition and treatment of acute exacerbation is provided in home exercise diaries which are kept over 8 weeks. Participants are encouraged to track their progress against their goals on a daily basis.
Home exercise diaries is delivered by the physiotherapist at the initial visit. Exercise diaries contains guidelines of identifying and managing moderate and severe exacerbation according to GOLD guidelines with an action plan, and contact details in case of emergencies. Following that, a goal setting sheet is provided to encourage goal setting at the start of every week with details about the time, location, and repetitions of exercises. A tracking sheet follows the goal setting sheet in order to help participants track their endurance and strengthening exercises daily.

Comparator / control treatment
Usual care (8 week) comprise of an advice to exercise 5 times a week for 30 minutes each session. This advice is directed to them through the initial phone call with the physiotherapist. Participants also recieve weekly telephone calls form physiotherapists to discuss general health in order to control for attention. Each weekly phone calls takes approximately 10 to 20 minutes. Participants allocated to usual care do not receive any feedback regarding their exercise participation.

Efficacy
Statistical methods / analysis
The mean improvement in 6MWD following traditional pulmonary rehabilitation in people with moderate to severe COPD is 48 metres, which represents a clinically important improvement. We anticipate that improvements in people with mild COPD will be at least as large. Assuming that the standard deviation of the change in 6MWD in mild COPD is 64 metres, a power of 0.8 and two-sided alpha of 0.0527, 58 participants (29 in each group) will be required to detect a difference in the change in 6MWD of 48 metres. The study will not be powered to detect differences in physical activity, symptoms or quality of life, but will provide preliminary data on which larger studies could be powered in the future.

Results will be expressed as mean and standard deviation (m +/- SD) values unless specified. Normality will be assessed using visual inspection and the Shapiro-Wilk test. All analysis will be performed using the SPSS software (version 22). Differences between group outcomes will be evaluated using a two-way analysis of variance (ANOVA) for continuous outcomes. The Chi-squared test will be used to evaluate the difference in categorical outcomes. A p-value of less than 0.05 will be considered to be significant.
