T6 complete, I have noticed that when I sit straight up, in my chair, or even being upright in my standing frame, that my back tends to arch so that if I put my hand behind me there is space between my spine and backrest down around the lower half of my back. The problem is my back only touches my backrest at the top edge of it because of the arch. I didn't even know it did this for years. Is this an issue with anyone else, and is it normal? Doctors and therapists have ever said anything, so I'm wondering if it's because some muscles aren't stretched like they should be, but I don't know which ones would cause my back to arch if they are tight. I don't know...
Why does my back arch...normal?
