Participant flow chat in this study. Simple randomization was used in this study. The 98 eligible patients were randomly assigned to either the experimental group (n = 49) or the control group (n = 49) prior to discharge by the researchers using a computer-generated random sequence. The patients in the control group received usual care without any type of instruction regarding exercise, while the patients in the experimental group received usual care plus telehealth exercise training. All patients in both the experimental and control group received a 4-month follow-up. A total of 83 participants completed the follow-up (42 in the experimental group and 41 in the control group).
