ADVERSE EVENTS
Success criteria for the feasibility trial include: (1) obtaining sufficient 6MWT data to allow for a formal sample size calculation based on the SD of this specific dependant variable; (2) attendance of ⩾ 75% of scheduled sessions; (3) loss to follow up is < 20%; (4) there are no serious adverse events resulting from the trial procedures; and (5) there are no significant difficulties for the researcher in administering the procedures or the intervention, measured by missing outcome data. The success criteria of this trial provided the basis of interpretation to determine whether a definitive trial is feasible.For measurements, continuous variables were described as mean ± SDs and frequency counts and percentages were provided for categorical data. As this study was not intended or powered to detect statistical differences in outcomes (e.g.,
