The structure and function of breathing – The structure function continuum

Nowhere in the body is the axiom of structure governing function more apparent than in its relation to respiration. This is also a region in which prolonged modifications of function – such as the inappropriate breathing pattern displayed during hyperventilation – inevitably induce structural changes, for example involving accessory breathing muscles as well as the thoracic articulations.

Ultimately, the self-perpetuating cycle of functional change creating structural modification leading to reinforced dysfunctional tendencies can become complete, from whichever direction dysfunction arrives, for example: structural adaptations can prevent normal breathing function, and abnormal breathing function ensures continued structural adaptational stresses leading to decompensation.

Restoration of normal function requires restoration of adequate mobility to the structural component and, self-evidently, maintenance of any degree of restored biomechanical integrity requires that function (how the individual breathes) should be normalized through reeducation and training.
