Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants with COPD will be invited to participate in this study
If they agree they will be consented and randomised into either the intervention group (IG) or the control group (CG)
The IG will complete the Montreal Cognitive Assessment (MoCa) (measure of cognitive impairment), then perform 20 minutes walking on a treadmill (walk speed determined from 80% of the six-minute walk test). They will then complete the MoCa again. The MocCa is administered by the physiotherapist in a quiet room in the outpatients department and takes about 30 minutes maximum to deliver. The delivery is face to face and one on one.
The 6MWT is performed as part of initial assessment for pulmonary rehabilitation before recruitment occurs.

The MoCA has been used as a screening instrument for moderate cognitive impairment by assessing memory, language, executive functions, visuospatial skills, calculation, abstraction, attention, concentration and orientation. There are alternate forms of the MoCA and version 2 will be used at T2

Rehabilitation
Comparator / control treatment
The Control group (CG) will perform the MoCa, then sit in a quiet room for 20 minutes and then perform the MoCa again. One observation will be made during quiet sitting and participants will be encouraged not to read or interact with their mobile phone during this time.
Control group
Active

Outcomes
Primary outcome [1] 304824 0
The Montreal Cognitive Assessment Tool (MoCa) is a questionnaire used to assess cognitive function (thinking and memory). MoCa Version 7.1 will be used at baseline (T1) before 20 minutes of treadmill walking or cycling and MoCa Version 7.2 will be used after the treadmill walking or cycling (T2).
Timepoint [1] 304824 0
T1 = baseline
T2 = end of 20 minutes of exercise
Secondary outcome [1] 343303 0
Heart rate will be measured using a finger probe connected to a portable oximeter
Timepoint [1] 343303 0
Every 5 minutes during treadmill walking
Secondary outcome [2] 343703 0
Oxygen saturation will be measured using a finger probe connected to a portable oximeter
Timepoint [2] 343703 0
Every 5 minutes during treadmill walking or cycling

Statistical methods / analysis
For the COPD group, 68 participants will be required to have an 80% chance of detecting (as significant at the 5% level), a mean increase of 2 points (minimum important difference) (Wong et al, 2017) in the MoCa, assuming a standard deviation of 2.9 points. (Krishnan et al, 2017). and allowing for a 15% dropout.
For the heart failure group, 62 participants will be required to have an 80% chance of detecting (as significant at the 5% level). A mean increase of 2 points (minimum important difference) (Wong et al., 2017) in the MoCa assuming a standard deviation of 2.6 points in heart failure patients (Gelow, Mudd, Chien & Lee, 2015) and allowing for a 15% drop out.
