I have severe thoracolumbar scoliosis, diagnosed at about age 60 and (initially) rapidly progressive. My neurosurgeon recommended surgery but also was realistic about it (I would never be pain free; and the surgery and recuperation were very significant and difficult). I opted instead to try non-invasive methods (yoga, particularly courses designed for scoliosis) and strength training and have done both almost daily since then. Eventually my spine curvature plateaued and even got a little better, and, per my neurosurgeon, sort of fibrosed into place. I'm glad I chose this route but recognize that surgery might be an appropriate option for others.
