A back brace can assist to relieve part of the weight that is generally exerted on the lower back, relieving strain on the spine's joints, discs, and muscles. A back brace, by lowering spinal pressure, may alleviate uncomfortable muscular tension, which is a common defensive response to an injury. A back brace prevents excessive motions from causing more harm to the back. This aids in the alignment of your spine and the strengthening of your back muscles. Your back can mend and your discomfort will subside.
