[Practical methods for controlled diaphragmatic breathing in 2009: proposals for a consensus].

BACKGROUND

This work has been completed at the request of the French Language Society of Pneumology. It is the result of collaboration between the 'Muscles and Respiration Group' and the 'Working Group in Physiotherapy', arriving at a consensus on diaphragmatic breathing.

RESULTS

From the literature followed by a formalized consensus methodology, the authors specify the terminology and define the appropriate methods of this technique that should be used.

CONCLUSION

Analysis of the literature to date does not allow assessment of the efficacy of this technique. The precise definition of the methods of diaphragmatic breathing as proposed in the present study will be used as a basis for forthcoming studies on this technique.
