The thoracic lumbosacral support brace provides support and stabilisation for back muscles, helps align the spine, and relieve back aches and spasms. The brace is recommended for thoracic kyphosis, lordosis, osteoporosis, and as a pre- or postoperative rehabilitation aid. It can also be used to help with rounded, slumped shoulders and to improve posture. The back brace is made of durable, lightweight, and flexible elastic cotton blend material, which is breathable and moisture wicking for increased comfort, thermoregulation, and moisture control. The properties of the fabric and the construction of the brace allow it to evenly distribute pressure, provide gentle compression and support, adapt to the shape of the body, and maintain freedom of movement. The brace features two steel and two metal removable stays to provide firm support to muscles and spine. The bendable steel stays can be adjusted to anatomically fit the body. The brace is equipped with adjustable criss-crossed straps for a secure fit, controlled compression, and customised adjustment to most body types. Soft contoured lumbar insert cushions the lower back, redistributing pressure and keeping the lumbar region tension-free, and providing additional stability. The slimline design of the brace and the ease of on and off make it possible to wear for extended periods of time under regular clothes. It is recommended to initially wear the brace for shorter periods of time, gradually increasing the amount of time worn to let the body adapt to the level of support. Due to its innovative features, the thoracic lumbosacral support brace offers instant relief and comfort, maintains the shoulders and back in a comfortable yet stable position, and allows to continue being active while healing the back.
