The SpineCor scoliosis brace is most effective when bracing starts before the 1st growth spurt, in what is called Risser 0. However, the SpineCor scoliosis brace has been shown to be effective in more advanced years of maturity, Risser Signs 1-3, as well. Compliant patients get better results.
TLSO stands for Thoraco-Lumbar Sacral Orthosis. A scoliosis brace could mean anything; every type of brace for scoliosis is considered a scoliosis brace. The most common TLSO brace in the US is the Boston Brace. However, this is also one of the least effective braces in my opinion.
