Usability testing for the TelePR platform
We performed in-lab and in-field usability testing to check interactions with the TelePR equipment and make necessary refinements [Adaptations included: having the RT review a checklist with participants (i.e., water, oxygen, if necessary, weights, band, and a phone in case of emergency), adjusting the tablet mounting on the bike, making the icons on the tablet larger, and for those patients unable to complete TelePR sessions without in-person support – having either a caregiver or study team member present during the PR session.
