Spinal Unloading Devices for the Treatment of Low Back Pain
Patient-operated spinal unloading devices have been investigated as a conservative, non-invasive treatment option for subacute and chronic low back pain for individuals who have not responded adequately to standard medical therapy. The intent of these devices is to provide a traction-like effect by shifting weight bearing off the lower back and onto the hips. The method used to shift weight bearing varies among devices. Some devices (e.g., LTX 3000™) utilize gravitational force provided by the body mass of the individual. The LTX 3000 consists of an adjustable seat strap and rib support pads that purportedly stabilize the upper body by engaging the lowest portion of the rib cage. After the rib support pads have been properly adjusted, the individual lowers the seat strap to induce unloading of the lumbar spine via the downward force provided by the individual’s body mass.Other devices (e.g., Orthotrac Pneumatic Vest™, STx™ Saunders Lumbar Traction Device, and Saunders Lumbar Hometrac™ Deluxe) utilize applied pneumatic pressure in an effort to shift weight bearing off the lower back.
Spinal unloading devices for the treatment of low back pain are considered investigational.

There is insufficient evidence from peer-reviewed published studies to conclude that axial spinal unloading devices are effective in the management of low back pain.
