In this study we develop the minimal important difference for the 1-minute sit-to-stand-test (STST) with an anchor-based method.~First step of this study is to find out the differences in the number of repetitions during 1-minute STST, 6-minute walk distance and health-related quality of life from pre to post inpatient pulmonary Rehabilitation program (3 weeks Duration) in the Schoen-Klinik Berchtesgadener Land.~In Addition, Balance tests on the Leonardo-Mechanograph will be performed and the Hospital Anxiety and Depression Scale (HADS) and Chronic Respiratory Questionnaire (CRQ) will be assessed.~For the second step we will use an anchor-based approach to estimate the MID of the STST. 6MWD and CRQ are used as anchors for which the MID has been established before.
The purpose of this study is to determine the minimal important difference (MID) for the 1-minute-sit-to-stand-test (STST) with an anchor-based method.
