This five-year follow-up study indicates that patients with dysfunctional breathing benefit from breathing retraining.

The results of the study indicate that patients with DB are more disabled than patients with well-controlled asthma. There is a great need for more knowledge about breathing symptoms of a dysfunctional nature, to be able to identify and manage these patients adequately.

The RMMI can be used to measure and analyse different breathing patterns in different body positions, and the correlation between measured RMs and breathing volumes is strong.
