Outcomes and follow-up
We chose the 10MWT at preferred and maximal speed
as primary outcome measures. Additionally, on a hypothesisgenerating
basis, we explored a broad range of secondary
outcome measures and we investigated the longitudinal
course of general pain by assessing it before and after each
training session. All outcome measures were applied
according to Figure 2. Follow-up assessments were performed
to investigate the sustainability of potentially induced
changes in outcomes. Given the cross-over nature
of this study, it was not possible to make statements about
sustainability for each intervention specifically.
