@rjd The TBS test is the only way I am aware of that gives that extra information. Though have to say I’m not familiar with the Echo test ,that has been mentioned on this forum. So on the TBS you get a color coded picture of each lumbar vertebrae with areas shaded in as such . Green for normal, yellow for partially degraded, red for degraded. There are actual scores that go along with this and provides scores of each vertebrae and combinations of them leading you also to an overall score.
I’m flattered , but my knowledge only touches the surface of what Dr. McCormack understands!!!!
Good luck to you as you navigate your situation!
