Distractive and mobility-enabling lumbar spinal orthosis devices, systems, and methods for treating mechanical low back pain

摘要

The present subject matter relates to orthotic devices, systems, and methods configured to support a lumbar spine. In some embodiments, a lumbar spinal orthosis system includes a torso belt configured to be secured about a torso of a user, a pelvic belt configured to be secured about a pelvis of the user, and a distractive force mechanism connected between the torso belt and the pelvic belt. The distractive force mechanism is configured to generate a force between the torso belt and the pelvic belt acting bi-directionally across a lumbar spine of the user to substantially offload bodyweight of the user passing through the lumbar spine.
