Description of intervention(s) / exposure
We are assessing the feasibility and accuracy of using a smartphone app to measure a remote 6 min walk test, to count steps, record GPS data and allow participants to respond to a questionnaire. Participants will install an app on their phone at clinic. They will perform 2 in clinic 6 minute walk tests while using the app. Over a 5 day study period they will perform 3 remote 6 minute walk test and provide a response to the WHO-DAS questionnaire using the app. The smartphone app will extract step counts from before their clinic appointment. During 2 months following the clinic appointment the smartphone app will report their step counts and GPS data wirelessly. These will be used to calculate daily step counts and walking speed. The GPS data will be used to calculate how much time they spend at home, how far they travel, how many destinations they visit and the geographical area they interact with on a daily basis using a convex polygon and standard deviation ellipse activity space.

Comparator / control treatment
The control will be 2 in clinic 6 minute walk tests, a fitbit One pedometer, a BT-Q1000XT GPS transponder and a questionnaire asked in person
Control group
Uncontrolled

Outcomes
Primary outcome [1] 305764 0
To assess the reliability of 6MWT distance recorded by a smartphone app in a remote environment. We will compare the distance walked between the two in clinic tests, calculating lins concordance coefficient and performing Bland-Altman analysis. We will assess for reliability by comparing the three walk tests performed during the 5 day study period

Statistical methods / analysis
Continuous data will be described by mean (standard deviation) or median [interquartile range] depending upon normality of distribution. Categorical data will be summarized as number (percentage). Between group comparisons will be performed by t-test, rank-sum, or chi-squared distribution of frequencies as indicated.
Where repeated measures exist, population average point estimates and between group comparisons will employ generalized estimating equations.
Concordance between like measures will be assessed by Lin’s concordance correlation statistic and Bland-Altman limits of agreement.
