3.3.2 Relative Contraindications
Report to and discuss with the physician any of the following: contractures of the spine, restricted
chest breathing ability, skin diseases/injuries, inflammation, raised scars with swelling, redden­
ing, and warming in the area where the brace is fitted, tumors, lymphatic congestion – including
unclear swelling of soft tissue distal to the medical aid, and dysesthesia in the legs.
3.4 Mechanism of Action
The three-point principle and the spring mechanism result in an effective and statistically signifi­
cant reduction of the muscle-force-induced compression of the movement segments and the
small vertebral joints in the lumbar spine region. Spine deformation occurs in both the sagittal
and the frontal planes. This applies for moderate as well as maximum loads. The brace effectively,
significantly and systematically reduces the load on the lumbar spine.
