Brief Summary in Lay Language

The purpose of this study is to investigate how the use of a smartphone application (COPD-APP) in combination with activity monitoring in patients with chronic obstructive pulmonary disease (COPD) affects physical activity, quality of life, physical fitness, symptoms, feeling and health. For this, we compare people who carry out the program at home for half a year (training group) with persons who perform only an activity monitoring and regular tests (control group).

Brief Summary in Scientific Language

The overall objective is to assess the effectiveness of the newly developed COPD-App as a maintenance program after Pulmonary Rehabilitation.
The primary objective is to assess the clinical efficacy of the COPD-App maintenance program on physical activity measured in steps/d in patients with COPD after 6 months.
Secondary objectives are to evaluate the effects of the COPD-App-program on
• Functional exercise capacity.
• Health-related quality of life (HRQoL).
• Patient reported health status.
• Exacerbations and depression and anxiety symptoms.
Other Objectives : Further we aim to explore the patients’ compliance/adherence and safety, identify factors which facilitate the implementation of the program in the patient’s home setting and to evaluate factors of the program which are especially supportive for the patients.

Interventions/Observational Groups

  •   Device : KAIA COPD-App (Mobile Application).
    The study intervention is an exercise training program that requires a chair and elastic bands, consisting of training elements with progressive levels of intensity, individually adaptable to the participant’s exercise level. This training program is delivered to the participants with the help of KAIA COPD-App. The individualized training sessions will last approximately 15-20 minutes and will be conducted by the participants seven days per week at home during six months of the trial period.
  •   Training of the control-group is performed by regular recommendations during the study period.

Primary Outcome

The primary outcome is the change in physical activity of the intervention group in comparison to the control group, measured over one week as mean steps per day comparing baseline to 6 months visit value.

Secondary Outcome

Secondary outcomes assessed are :

Exclusion Criteria

• The Patient is not able to conduct the exercise training program due to physical, cognitive or safety reasons, as judged by investigator; e.g., lower limb joint surgery within preceding 3 months, unstable cardiac disease, predominant neurological limitations, planned surgical or other interventions disturbing the study intervention.
• Significant psychiatric disorders, legal incapacity or limited legal capacity.
• Patients participation in another clinical trial with an investigational medication within 30 days prior to study entry.
