Backsavers for horseback riding? Advice anyone?

I have broken my back and was told I would never ride again...once I was able to walk properly it didn't take me long to figure out how to get back to riding. I wear a brace similar to that and it helps to support the part of my back where the muscles were ripped. Unfortunately the pain usually sets in after about an hour and I have to get off. A body protector doesn't have the support that the back saver does but it wouldn't be a bad idea to where both in combination. And yes, I always hold in the back of my mind that if I come off wrong I have a chance of being a paraplegic. But I got thrown pretty good last year (not my horse)-didn't hurt my back at all-but I broke my leg in four places!! And yup, as soon as I could figure out how to get on my horse I was back on!
