Spinal bracing adds strength and gives support to spinal discomfort and strain, as it helps relieve the pain from pressure injuring the nerves in the spine. Lightweight frame with foam liner encourages abdominal compression which allows pressure on the vertebral column to unload (providing relief). Recommended for herniated disc, osteoarthritis, spinal stenosis and compression fractures. Sizes (measure at waist): MD (36"-41"), LG (42"-47"), XL (48"-53"). Brace measures 9.5" in front and 14" high in back.
