Uses a 3-point biomechanical leverage principle to restrict flexion and help stabilize the spine. The pads are joined with a lightweight, totally adjustable low-profile cruciform frame. Horizontal adjustment 11.25"-14"; vertical adjustment 12.5"-18.5". The control of flexion is obtained by the soft pads; the cruciform frame does not contact the patient. The pectoral model disperses the posterior force and applies it to the more resilient muscles. To keep skin cool and protected, wear a cotton shirt underneath. You may shower, bath or sponge clean while wearing the brace. Brace cleans easily with mild soap and water. Latex free.
