Spinal bracing utilizes these primary objectives. Controlling back pain by limiting motion and unloading discs, vertebrae and other spinal structures by compressing the abdomen. Stabilizing weak or injured structures by immobilizing the spine. Providing three-point force systems to provide correction or prevent progression of a deformity. The segment of the body that is being controlled generally classifies spinal bracing terminology.
Control is described in terms of spinal flexion, extension, rotation and lateral bending.
Spinal orthoses are categorized as flexible, rigid or semi-rigid. Flexible orthoses or corsets are prescribed for relief of low back pain associated with degenerative disc disorders, trauma or postural deformities. Corsets are typically made of cotton and nylon materials. Corsets are used to de-weight spinal structures by increasing abdominal compression. Rigid stays and inserts can be added to restrict motion and act as a postural reminder.
