Trial Results

  • Improvements in Symptoms Scores (2 studies)
  • Improvements in Quality of Life Scores (6 studies)
  • Reduction of ICS use (6 studies)
  • Reduction in Inhaled Beta-agonist use (5 studies)
  • Improvements in Asthma Control (3 studies)

In addition to reduction in medication patients experienced significant improvements in measures of quality of life scores, symptom scores, and also a reduced number of courses of oral steroids.

"I've been astonished and also very pleased with the excellent result. There is no disruption of their life at all by their disease: normal activities; not waking at night; not needing to use any reliever medications. It's just great...75% control is about as good as anyone has got in any study of asthma. The neat thing about it is that it has no side effects. It's very safe. The Buteyko technique certainly has been shown to be an important adjunct to treatment."

Dr. Robert Cowie, Resident Respirologist of Foothills Hospital in Calgary and head researcher on the Buteyko Breathing Technique Medical Trial. (October 2004 – April 2005).
