The L0650 is an "off the shelf" Lumbar-Sacral (back) Orthosis which meets certain requirements and standards. This back brace must provide rigid support for the anterior and posterior, or front and back, of the brace. This brace must also have rigid lateral (side) support, giving strength to the sides. L0650 braces create pressure to evenly distribute weight in order to take the strain off the spinal discs. The front and back of the brace must extend from the tailbone to the T9 vertebrae (which is near the middle of the back).
