3 Intended use
3.1 Indications for use
The brace is intended exclusively for orthotic fittings of the back and exclusively for contact with
intact skin.
The brace must be used in accordance with the indications.

With pain syndromes of the lumbar spine caused by:
• Lumbar spinal canal stenosis
• Lumbar facet joint syndrome
• Lumbar radicular syndrome (anterior thigh pain, lumboischialgia)
• Lumbar instability (spondylolisthesis, spondylolysis)
• Lumbar spondylarthrosis
• Intervertebral disc prolapse and protrusion in the lumbar spine area
• General degenerative changes with reduced intervertebral disc height

3.3 Contraindications
3.3.1 Absolute Contraindications
None known.
3.3.2 Relative Contraindications
Report to and discuss with the physician any of the following accompanying symptoms: contrac­
tures of the spine, restricted chest breathing ability, skin diseases/injuries, inflammation, raised
scars with swelling, reddening and warming in the area where the brace is fitted, lymphatic con­
gestion – including unclear swelling of soft tissue distal to the device, and dysaesthesia 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.
