The difference is that you don't charge patients extra for using the backboard. But you can sure as hell charge a patient extra for moving their fascia around to 'promote the body's innate ability to fight infection and restore mind, body, and spirit.'
Also, what do you mean backboards in trauma pts? What would you like them to use in the field?
For spinal immobilization? A firm mattress. If you need to use one to move a patient, then sure (albeit a scoop is better than a backboard), but for general transport, a backboard isn't needed, none of it is supported by any evidence that it reduces incident of spinal injury.
