The Papworth Method is a specific diaphragmatic breathing technique that was developed in the 1960s at Papworth Hospital. The technique emphasises nose breathing and the development of a breathing pattern to suit current activity. It also involves relaxation exercises that, in concert with the breathing technique, have been purported to aid depression and anxiety (source: Wikipedia).
In a recent study, 39 adults patients with asthma were assigned to integrated breathing and relaxation training (the Papworth Method) for 12 months.
The Papworth Method appeared to help respiratory symptoms, dysfunctional breathing and adverse mood compared with usual care. The treatment and control group did not differ significantly in the objective measures of respiratory function (PFT) though.
Summary: The Papworth Method may improve symptoms but not PFT measurements in adult patients with asthma.
