RedactedNarrative: I was requested to respond to a medical call by the concession operator at East Canyon State Park.  I responded to the concession courtesy docks and found a vessel tied to the dock with subject as the operator of the vessel and subject2 as the owner.  VICTIM was laying on his back in the rear of the vessel with his head supported by his father.  VICTIM had been tubing behind the boat on one of two tubes being towed.  The tubes had collided and VICTIM was thrown off the tube.  He hit the water and had severe pain in his mid and lower back and lost the use of his legs.  When I arrived I found VICTIM alert and conscious and shivering.  He had feeling in all his extremities.  He claimed his back pain was lessening but still could not move his legs.  I performed a basic evaluation and could not find any severe injury and requested that Weber Dispatch send an ambulance since this appeared to be a back injury.  In waiting for the ambulance VICTIM was in lessening pain and could move his legs.  It appeared that he had suffered severe cramping in his legs.  The paramedics arrived and performed an evaluation.  They discovered no injury and released him to the care of his father and leaders.
