A critical review of dysfunctional breathing

Abstract

Dysfunctional breathing (DB) refers to various abnormalities breathing patterns. Whilst a formal definition exists, subsequent research has inconsistently applied or omitted it. As interest in breathing techniques grows among both healthcare professionals and the public, it is important to reach a consensus on DB's definition to ensure effective assessment and treatment. This critical review explores how DB is currently defined and applied within respiratory and musculoskeletal health. A lack of consistency in the literature identified the need for a more comprehensive framework of DB. To address this, a new model of DB is proposed that includes three subcategories: biomechanical, biochemical and psychophysiological DB. This revised model offers a foundation for future research and clinical application.
