Patients demonstrated significant improvements in TUG scores
after PR (mean change − 1.7 ± 1.4 seconds; P = .001; effect size =
1.249). Before PR, 9 (41%) participants and after PR only 1 (4.5%)
participant had a TUG performance worse than the average performance
of age-matched healthy peers ( P = .008). The St George’s
Respiratory Questionnaire symptoms score ( P = .012), quadriceps
muscle strength ( P = .001), and exercise tolerance ( P = .001) were
also improved.
