Operationalization of the criteria to evaluate feasibility.

Parameters	Definition	Criteria/examples
Source of recruitment	The method used to recruit each youth.	In clinic, postal mail, phone, social media
Recruitment rates	From a list of patients with AMCa followed, the number of eligible youths will be determined. Those that are reachable will be accounted.	≥50% of eligible and reachable youths
Withdrawal rates (before the intervention)	Youths who will consent to participate but will withdraw before the start of the intervention will be accounted.	≤20% of the youths who consent
Withdrawal rates (during the course of the intervention)	Youths who will complete at least one telerehabilitation meeting and will decide to withdraw afterward will be counted. The time points when they decide to withdraw will be collected as well as the reason, if applicable.	≤30% of the youths who start the intervention
Completion rates	The number of youths who will complete all 6 telerehabilitation meetings out of those who have consented.	≥50% of the youths who consent
Compliance to the HEPb	The amount of time youths performed their HEP will be collected using a participant-completed log sheet and data from the physical activity monitor.	≥50% of compliance to the HEP
Compliance to the telerehabilitation meetings	The number of meetings cancelled the same day among the meetings that occurred, as well as lateness to the meetings. Lateness is defined as joining the meeting 15 minutes or more after the scheduled time.	≤15% of the meetings
Missing data	The number of questionnaires not completed and the number of unusable range-of-motion data.	≤10% for each outcome
Technical issues	Problems that will arise and disrupt or delay the meeting or possibly prevent the telerehabilitation meeting from taking place.	Echo voices, connection, image quality
