In the active group, one of the co-investigators will install and demonstrate the use of the mobile app (Rehab App) on participants' mobile phone and explain the use of the software. The participants will be followed up for the duration of their enrolment in the e-health and tele-rehabilitation service, which can last up to 2 months.

Participants in the control group will get the usual treatment from the clinical staff and in-person education, and they will be supervised by one of the assigned research team members every week.
