Questionnaires such as the clinical COPD questionnaire (CCQ) and COPD assessment test (CAT) have till now been mainly used for defining severity, e.g. in the new GOLD classification and during clinical follow-up. However, these questionnaires might also be useful in the assessment of effects of PR.Aim: To investigate if ESWT, CCQ and CAT are responsive instruments to measure changes after pulmonary rehabilitation.Methods: In this prospective study patients with COPD received a 9 weeks{\textquoteright} multidisciplinary PR program. ESWT, CCQ and CAT were assessed before and after rehabilitation. Internal responsiveness was investigated by paired t-tests or Wilcoxon signed rank test and by calculating effect sizes.Results: 62 COPD patients were included (31 men, mean+SD age 59.5{\textpm}9.0 years, FEV1 42.3{\textpm}18.0 \%pred, ISWT 200{\textpm}112.3m and baseline CCQ and CAT resp. 3.1 and 24.6). After nine weeks of rehabilitation ESWT, CCQ and CAT scores significantly changed compared to baseline (Table). The change in ESWT did not correlate with changes in CAT or CCQ.View this table:Conclusion: ESWT, CCQ and CAT significantly improved after PR and effect sizes of all parameters were also clinically relevant. ESWT, CCQ and CAT seem to be responsive instruments for evaluating effects of PR.}, issn = {0903-1936}, URL = {https://erj.ersjournals.com/content/44/Suppl_58/P3047}, eprint = {https://erj.ersjournals.com/content}, journal = {European Respiratory Journal} }
