Waist and upper body orthoses are orthopedic supports designed to stabilize the lumbar and thoracic spine, limit excessive motion, and reduce mechanical stress on vertebrae, discs, and surrounding soft tissues. By providing controlled compression and structural reinforcement, they promote proper spinal alignment while allowing functional mobility during recovery. These devices are commonly used for lower back pain, postural imbalance, ligament strain, post-traumatic care, and post-operative support, with designs ranging from elastic belts to rigid splinted braces depending on the required level of stabilization.
