First Aid Guidelines often advise using the Long spine board or backboard when a spinal injury is suspected. Paramedics and EMS Agencies are ceasing the use of the Backboard as a treatment, however it remains in many first aid courses.
The Canadian C-spine protocol can work to determine if the mechanism of injury warrants backboard use. First Aid protocol ends up being subject to interpretation, of severe injury in the absence of a detected paralysis so these rules can help.
