Study type
Interventional
Description of intervention(s) / exposure
On completion of a pulmonary rehabilitation program, participants will be randomised to either Group 1 or 2 using a computer-generated random number sequence. Following randomisation, a Research Assistant will visit the homes of all participants. Those participants randomised to Group 1 will receive a wheeled walker during the first home visit and a Research Assistant will provide standardised instructions regarding its use and encourage daily ambulation with the device. Those participants randomised to Group 2 will receive encouragement regarding daily ambulation, but no wheeled walker. Four weeks after the first home visit, participants will be provided with two devices that measure physical activity and instructed to wear the devices for 5 days. At the end of these 5 days, a Research Assistant will perform a second home visit to collect the devices and other outcome measures. Those participants randomised Group 1 will have their wheeled walker removed and those participants randomised Group 2 will have a wheeled walker issued and be provided with standardised instructions regarding its use. During this home visit, all participants will receive the same encouragement from a Research Assistant to perform daily ambulation. Four weeks later, participants will again be provided with the devices that measure physical activity and instructed to wear them for 5 days. At the end of this 5 day period, a Research Assistant will perform a third and final home visit to collect the devices and other outcome measures. The four week period of time without the wheeled walker represents the 'wash-out' period.
Intervention code [1] 4387 0
Treatment: Devices
Comparator / control treatment
At the beginning of the control period, participants will receive encouragement to ambulate during daily life. They will continue to receive usual medical care. That is, they will continue with their usual medications and see their doctor as required. This will be the same for all participants during the control period. The control period will be 5 weeks in duration (four weeks "wash-out" and one week of assessment).

Timepoint [3] 241737 0
The number of wheel revolutions (i.e. wheeled walker use) made during the time the participant has the device will be recorded. That is, wheeled walker use will be recorded once 4-5 weeks after enrollment or once 9-10 weeks after enrollment.
Secondary outcome [4] 241738 0
Preference (with vs. without wheeled walker) will be measured using standardised questions.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Potential participants will be identified during participation in a pulmonary rehabilitation program. Once consent is obtained, subjects will be randomly allocated to one of two groups. The randomisation sequence will be concealed using opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer generated random number sequence, blocked for groups of 4, stratified according to oxygen use.
Masking / blinding

Summary
Brief summary
This study will determine: (i) to what extent people with COPD choose to use a wheeled walker in day-to-day life; (ii) whether providing a wheeled walker for use in their home and community increases their level of daily physical activity and; (iii) whether use of a wheeled walker improves quality of life or increases an individual’s confidence to walk (i.e. they feel less fearful of falling).

A total of 30 patients with COPD will participate in the study. On the completion of a pulmonary rehabilitation program, people with COPD that are considered appropriate for a wheeled walker will complete two consecutive four week “periods”. During one of these periods, but not the other, they will have a wheeled walker provided for use during daily life. Measurements of wheeled walker usage, daily physical activity, quality of life and fear of falling will be collected on completion of each four-week period and compared in order to determine the effect of a wheeled walker on these outcomes.
