This Insert is effective at providing thoracic and head support for the mild, moderate, or severely involved user who typically hyperextends at the trunk and retracts the scapulae. With the pelvis properly positioned in the appropriate chair, the Winged Back Insert encourages scapular protraction and normal spinal alignment. The Insert is both height and depth adjustable. It comes standard with a mounting yoke, butterfly anterior chest support, a posterior head pad, and lumbar pad.
