Structure and Function: A Two-Way Relationship

In osteopathy, we understand that structure and function are intimately connected. When the structure of a tissue is altered — whether due to trauma, illness, or impaired blood supply — its function is inevitably affected as well.

A clear example of this is pneumonia. This lung inflammation can cause scarring that is often visible on an X-ray. Patients typically experience coughing, shortness of breath, and difficulty breathing. What’s happening is that the lung’s structure — particularly the alveoli where oxygen and carbon dioxide exchange occurs — is impaired, reducing both gas exchange efficiency and overall lung mobility and thoracic mobility.

Structure and Function Two-Way Relationship

In my practice, I frequently see patients presenting with chest, neck, or shoulder pain several weeks or months after a bout of pneumonia or bronchitis. When lung mobility is compromised, the muscles that attach to the rib cage, neck, scapula, and shoulder often become shortened or tense in response. I see clients with pain in their neck during their sleep. This is caused by limited mobilité of the thoracic spine leading to a decrease mobility in the cervico-thoracic junction.

This structural issue leads to limited movement of the ribs, spine, and shoulder, which can result in postural strain, reduced energy, and persistent discomfort in the upper body.
