A Boston Brace is only a two-dimensional solution for a three-dimensional disease. The brace restricts and weakens the entire abdomen, making it difficult for the spinal discs to regenerate themselves. It is a type of thoraco-lumbo-sacral-orthosis, or TLSO brace. Its used primarily for the treatment of children, working to slow the progression of scoliosis in growing spines. Boston Brace is made of rigid polypropylene material and people wear it by wrapping it around your chest, ribs, back and hips.
