Effectiveness of a Buteyko-based Breathing Technique for Asthma Patients
- Conditions
- Asthma
- Registration Number
- NCT03098849
- Lead Sponsor
- ARCIM Institute Academic Research in Complementary and Integrative Medicine
- Brief Summary
The purpose of this study is to investigate the effects of a Buteyko-based breathing technique on physiological and psychological parameters in adults with asthma
- Detailed Description
The investigators explore the effects of a Buteyko-based breathing technique training using a treatment group vs. control group design and a repeated measures design with follow-up measurements 3 and 6 months after the intervention. The sample size calculation was made for an effect of d = .20 with repeated measures, a power of 1- β = .80 and α = .05. Additionally the investigators plan to take measurements (only once) from healthy volunteers matching them (age and gender) with the asthma patients.
