Kyrgyz Asthma Rehabilitation at High Altitude
Asthma Rehabilitation at High vs. Low Altitude: Randomized Controlled Parallel-group Trial
Studieoversikt
Status
Forhold
Intervensjon / Behandling
Detaljert beskrivelse
Low altitude baseline measurements will be performed in Bishkek. Participants will then either be assigned to a rehabilitation program in Bishkek (760m) or in Tuja Ashu (3200m).
The rehabilitation programs in high or low altitude will be identically performed and will comprise
- asthma education and awareness
- instruction on inhaled therapies
- smoking cessation counseling
- respiratory and skeletal muscle training in groups
- guided walks / cycle ergometer training
- questionnaires on asthma control, quality of life
- spirometry and peak flow measurements
- echocardiography
Measurement on study subjects will be performed at baseline (Bishkek), during the rehabilitation program, after completion of the rehabilitation program and during a follow-up at week 15.
