Physical activity
At the beginning of the study, 5 out of 6 (83%) patients in the experimental group and all (100%, 8/8) in the control group engaged in regular walking activity. After 6 months, all (6/6, 100%) patients in the experimental group were able to walk regularly; however, in the control group, the number of patients walking regularly decreased to 6 out of 8 (75%). Notably, no patients in the experimental group were capable to tolerate moderate physical activity at baseline, but 1 (17%) patient in this group tolerated it at the EoT.
