Welcome to our group. It is wonderful that you are looking for information to help your wife. My Hubby is there with me also, it just hurts him that he can't make me better.
I'm also planning on getting the scs. i've put it off long enough. I do know that you have to have a trial first to see if it will help. then you get the regular one. I do know that the recovery is very hard, but it should be worth it. if not, they can always take it out.
there are others here that have it, and I know they will be able to give you a lot more information that i can. I see my PMD on the 17th, and will put it into motion.
