**4.1 A randomized pilot feasibility study**

In 2017–2018, we conducted a small medical pilot project to assess:

1.The feasibility to perform home-based CR exercise using the MedBike system;


We hypothesized that home-based CR using the MedBike system is feasible and will effectively improve program compliance using VR gamification and patient risk factor reduction by real-time monitoring. To prove this hypothesis 11 subjects (5 controls) were recruited into a feasibility randomized pilot control trial. Inclusion criteria was:
