The BOA Dual TLSO is a unique prefabricated orthosis (patent pending) for post-operative, post-traumatic, or chronic spinal pathology. The Dual TLSO provides full-circumferential rigid support from the scapular thoracic region (T2/T3) of the spine down to the Sacroccygeal junction (S1). The BOA TLSO design creates a 3-point force system, consisting of a posteriorly directed force from the sternal and pubic pads, and an anteriorly directed force from the thoracolumbar pad. The pressure created restricts forward flexion and encourages a hyperextension posture. This posture increases lumbar lordosis and resists lateral and rotary movements of the spine.
