Study & Design

Study Type: interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
The two primary endpoints are dyspnea measured by COPD Assesment Test (CAT) score and physical performance measured by the repetition number of the 1-minute sit-to-stand test [time frame: Baseline at the beginning of the intervention (day 0); beginning of the second half (week 4); end of the intervention (week 8); end of the observation period (week 20)].

Secondary Outcome Measures

Name	Time	Method
All other endpoints are secondary endpoints. These will be evaluated at regular intervals during the study and after a follow-up period 12 weeks after baseline measurement. The secondary endpoints are: <br>Quality of life measured by Chronic Respiratory Disease Questionnaire (SAS-CRQ). <br>Number of steps per day as mean over one week from baseline<br>Subjective health status measured by feeling thermometer scale <br>Incidence and duration of patient-reported exacerbations<br>Incidence and duration of hospitalizations<br>Ease of use assessment<br>Rate, number and severity of device defects<br>Rate, number and severity of adverse events
