In 1921, a doctor named Walter Truslow published a book entitled The Non-Operative Treatment of Scoliosis.  Blazing new territory for scoliosis treatment options, the book featured a series of exercises designed to correct and maintain scoliosis.  Although not currently used for scoliosis treatment, but loaded with beautiful and graceful imagery, the book is now available in the public domain.  It's fascinating to learn a bit about the evolution of treatment options.
