No, anti-pyramiding rules would prohibit two ratings. The only way to add to the rating for your back is if you have a neurological condition(s) from spinal cord related issues.Yep that is what I was wondering, if it would be between 40 or 50, because the rest of the movements are frozen. And would I get 40% for each of my lumbar conditions? Lumbar Spondylolisthesis and lumbar spondylolysis? Thank you!
