BraceAbility's LSO Sciatica back brace is a unique disc unloader support that eases pain by taking pressure off the lumbar discs and shifting the load to your abdominal region. The lumbosacral support is constructed of lightweight, soft material that is breathable and non-irritating to your skin. The anterior and posterior panels of the sciatica back brace can hold anatomically designed inserts, supporting the natural curve of your spine. A reusable gel pack is also included, providing your choice of cold or hot therapy, if desired.
