The ISO Preferred Lumbar Back Brace VI (BA206) features a back plate combined with rigid front and lateral support panels. The heat moldable rigid back plate is shaped to conform to natural body contouring from the sacrococcygeal junction to the T9 vertebra. The rigid lateral and front panels help provide stable intracavitary abdominal pressure and thus reduce the load on the intervertebral discs and help provide better tissue healing after injuries around the lower back. The universal fit and padding of the wraparound design combines a rigid back plate with a rigid front panel to provide lumbar-sacral support and sagittal control. The brace uses an adjustable string and roller system that perfectly supports the lower back and core muscle while allowing for pendulous abdominal placement. Waist belts can be trimmed to fit sizes S to 2XL (up to 56” waist). Universal size. For 3XL to 5XL, the Large Kit for this item includes two (2) 9” belt extensions (ISO-BA202 Lumbar Belt Extension: Universal) and fits up to 74” waist.
