Cervical Spine Posture Changes in Patients with Obstructive Sleep Apnoea

This landmark study examined the spinal posture of adults diagnosed with Obstructive Sleep Apnoea (OSA). The researchers found a consistent pattern: the worse the apnoea, the more the head was pushed forward and the neck was extended.

The body was doing what it had to do — tilting the head to keep the airway open during sleep. But over time, that temporary survival reflex became a permanent postural change. Even after CPAP treatment normalised breathing, the posture didn't snap back.

This matters because millions of people are treated for "neck problems" and "postural issues" without anyone asking the fundamental question: why is the head forward in the first place? The spine is adapting to an airway that doesn't have enough space.
