How long on average does it take for someone who just got a Spinal Cord injury to be released from the hospital if they happen to be diagnosed with being a Paraplegic?

As far as I know, they return to the hospital and/or go to places that specialise in dealing with people with spinal cord injuries, like physiotherapy and other medical treatments that they need.

As a younger person, living in a small city, the physio there was located in the hospital. I don't have a spinal cord injury, but I do have a physical disability.
