[|Human|] My sister had surgery a few years ago and had metal plates put in her back. the pain is excruciating. would it be safe for her to use those back stretchers that turn you upside down? I believe they are called inversion tables. also what types of exercise could she perform that will help her elevate the pain as well as loose weight. I believe is she weren t so heavy the pain would be less. is that true?
[|AI|]  Inversion therapy doesn't provide lasting relief from back pain, and it's not safe for everyone. Inversion therapy involves hanging upside down, and the head-down position could be risky for anyone with high blood pressure, heart disease or glaucoma.
