Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients with quadriplegia will be supplied with a Mandibular Advancement Device (MAd or oral appliance) to wear every night during sleep for approximately 6 months. A MAd is modified mouth guard that gently pulls the lower jaw forward during sleep. This pulls the airway open and thus prevents the airway from collapsing and obstructing airflow.

Treatment: Devices
Comparator / control treatment
This is a feasibility study and as such there is no comparator or control treatment
Control group
Uncontrolled
