LordoLoc is suitable for use as a back support for the stabilization of the lumbar spine, for example in the event of chronic lumbar vertebral syndrome. The stabilizing orthosis with four 91/4" integral anatomically contoured flexible lightweight aluminium stays has a muscle-activating effect, relieves the spine and is very low-profile. The degree of stabilization can be adjusted to provide optimal individual support to the lower back. LordoLoc is characterized by its extremely thin yet effective construction. The supple support consists of two adjustable straps and four 91/4" corset stays made of flexible lightweight aluminum inserted at the back. The rods support the spine if an activation of the musculature alone is not sufficient. The tighter the upper strap is fastened, the greater the stabilization.
