RESULTS: Both groups showed substantial and similar improvement and a high proportion with asthmacontrol 6 months after completion of the intervention. In the Buteyko group the proportion with asthmacontrolincreased from 40% to 79% and in the control group from 44% to 72%. In addition the Buteyko group had significantlyreduced their inhaled corticosteroid therapy compared with the control group (p=0.02). None of the other differences between the groups at 6 months were significant.
CONCLUSIONS: Six months after completion of the interventions, a large majority of subjects in each group displayed control of their asthma with the additional benefit of reduction in inhaled corticosteroid use in the Buteyko group. The Buteyko technique, an established and widely recognised intervention, or an intensive programme delivered by a chest physiotherapist appear to provide additional benefit for adult patients with asthma who are being treated with inhaled corticosteroid.
