Rigid and Semi-Rigid Orthoses for Lower Back Pain

Rigid braces consist of a sturdy layer of material (typically cotton or canvas) that wraps around the torso, and includes rigid panels that cover the front, back, and sometimes sides of the brace. Some models include hard plastic or metal bars that cover the outside of the brace.

A back brace that combines elements of both flexible and rigid orthoses may be referred to as a semi-rigid brace. For instance, a flexible lumbar belt may include additional padding or molded plastic inserts for some additional support and stability.

Customized to Fit Your Needs

In one study, disability index and pain scores improved more when participants used a rigid back brace compared with a flexible brace. 

A rigid back brace may be custom-made or assembled from a selection of pre-made parts. In either case, a doctor, orthotist who specializes in designing and fitting braces, or other qualified health professional will measure and fit the brace to ensure it is safe, comfortable, and effective.

Flexible Corsets and Belts Can Help Relieve Lower Back Pain by:

• Applying light pressure to the torso to help adjust posture and shift weight off of the spinal column
• Providing some added spinal support to take pressure off of weakened or injured muscles
• Moderately limiting range of motion to allow for some bending and twisting. For instance, while wearing a flexible brace, it may be possible to bend forward enough to touch the top of the knee, but not past the knees
• Reducing micro-motion at a loose or weakened joint through compression of the torso or pelvis (especially in lumbar and sacroiliac joint belts)
• Relaxing tense muscles through the warmth of the brace

It is recommended to consult with a doctor on the appropriate size and fit of a flexible brace to ensure the brace is safe to use and likely to provide effective pain relief.
