I don't think you've got a diagnosis yet of what your horse needs a rehab for. You need more investigations to find out what is wrong. As far as I can tell from what you have written, your vet hasn't blocked out the back to test if it's that, or investigated the hind legs at all. They just seem to have jumped to the conclusion that it's the back on the basis of two close, but not touching, process which would be found on a high proportion of back x rays of horses with no issues.
