Genioglossus reflex responses to negative upper airway pressure are altered in people with tetraplegia and obstructive sleep apnoea

Key points class="unordered" style="list-style-type:disc" id="tjp12925-list-0001">Protective reflexes in the throat area (upper airway) are crucial for breathing.Impairment of these reflexes can cause breathing problems during sleep such as obstructive sleep apnoea (OSA).OSA is very common in people with spinal cord injury for unknown reasons.This study shows major changes in protective reflexes that serve to keep the upper airway open in response to suction pressures in people with tetraplegia and OSA.These results help us understand why OSA is so common in people with tetraplegia and provide new insight into how protective upper airway reflexes work more broadly.
