The most common form of a TLSO brace is called the “Boston brace”, and it may be referred to as an “underarm” brace. This brace is fitted to the child’s body and custom molded from plastic. It works by applying three-point pressure to the curvature to prevent its progression.
It can be worn under clothing and is typically not noticeable. The TLSO brace is usually worn 23 hours a day, and it can be taken off to swim, play sports or participate in gym class during the day.
This type of brace is usually prescribed for curves in the lumbar or thoraco-lumbar part of the spine.
