For quadriplegics, there would be loose wires to find and retrain. One could
imagine learning to run again without any risk of falling, and then swapping in
the mechanized legs once training was done. A simulator would need to capture
rigid body physics, and terrain and handle I/O with the nervous system such
that the host would feel as if they were standing, sitting, running, etc. even
though it was virtualized.
