Home-based structured exercise program (HSEP)
This strategy included the WA and an additional HSEP with aerobic walking exercises and resistance exercises. Patients were instructed to perform three 50-min exercise sessions weekly at home, for a total program duration of one year. The first six months was structured, with feedback from the physiotherapist by biweekly phone calls and two face-to-face visits. For the remaining six months, patients were instructed to continue with the prescribed HSEP but without further feedback.
