Similar to other studies, which have assessed the
effects of PR on patients with COPD, significant
improvements on activities limitation resulting from
breathlessness, HRQOL, muscle strength, and exercise
tolerance were found. This shows that the implemented
program was, overall, at least as effective as
it has been previously reported. Regarding the effect
of the program on patient functional balance, a
change of − 1.7 ± 1.4 seconds in TUG score was
found. This result is slightly higher than the value
obtained by Beauchamp et al 9 ( − 1.5 ± 2.4 seconds).
In our study, the ES for TUG test was much larger (ES
= 1.249) than in theirs (ES = 0.625), indicating that
PR with a specific component of balance training may
