Stainless steel supports along the spine provide stability & support for people who are suffering from low back pain. Once adjusted to the desired level of support using the high quality Velcro fasteners, the Lumbar Back Brace with removable pad acts like a corset to re-enforce the spine & torso. The stainless steel supports help to facilitate good posture by preventing a slouched position in the lower back. By keeping the lower back in an upright or extended position then there is less strain on the pain producing structures of the lower back, such as muscles, ligaments, discs & nerve roots.
