Lumbar Traction Brace with Rigid Panels & Step Down Support

The patented Expander Max LSO features a unique air pocket expansion system that provides effective sagittal-coronal control. Posterior panel extends from sacrococcygeal junction to T-9 Vertebra and wraps around torso to provide lateral strength and support.

When inflated, the Expander provides traction between the inferior of the rib cage and the superior part of the trochanter creating weight-bearing forces away from the lower back and reducing pressure in the lumbar spine. The plastic panels on the Expander can be removed to adapt to all facets of the patient’s rehabilitation. The Expander is lightweight and can be discretely worn under normal clothing.

Expander Mechanism

The Expander Traction LSO is vertically expanded by approximately 7 cm (2.8”) providing spacing between the intervertebral disc.
11cm Tall before inflation | 18cm Tall after inflation

  • One high quality study found that Expander Braces actually help improve strength lost due to lower back injury - finding 16% increased strength, 93% increased flexibility and 73% reduced pain after 6 weeks use (Sports Med Train& Rehab 1991, 2(2) p 121).
  • A 2005 study found particular efficacy in relieving radicular symptoms - 100% of users reported decrease or disappearance of radicular pain (Acta Neurochir suppl. 2005;92:133).
  • A prospective, randomized, controlled study at the Texas Back Institute found 6 to 8 times greater relief of leg & back pain, and 4 times improved functioning and flexibility after 12 weeks of use (Orthofix).
  • A Cleveland Clinic study found a 23% decrease in intradiscal pressure at L4-L5.
