In cases of lumbar vertebral syndrome or severe muscular weakness of the spine, LumboLoc Forte acts as a fixed support on the lumbar spine. Integral corset stays at the back support an anatomically correct posture. In addition, two different pressure cushions (pads) in the orthosis can be used to massage either the lumbar region or sacrum. LumboLoc Forte incorporates anatomically contoured corset stays made of aluminum which provide effective support for the painful area of the lumbar spine. The corset stays can be individually shaped for a perfect fit. An adjustable function belt at the front exerts a variable degree of compression on the abdomen and thus relieves the lumbar spine.
