Bracing is a temporary treatment option for spondylosis, one more often used for spondylosis in the neck (cervical spine). Braces can, however, also be used for spondylosis in other regions of the spine, such as the low back (lumbar spine). A brace will help control your pain by limiting motion. Braces also help support your spine, taking some of the pressure off your vertebrae. Additionally, braces can help the muscles relax, and that relaxation alone can provide a level of pain relief.
Long-term bracing isn't usually recommended because it can cause the spinal muscles to weaken. It's better for you to go to physical therapy to learn how to strengthen your muscles so that they better support your spine.
Your doctor will decide if bracing is a good option for you, what kind of brace you should wear, and how long you'll need to wear it. With a brace, it's absolutely critical that you follow the doctor's order exactly for how and when you're supposed to wear it. If you don't, the brace won't be as effective at relieving your pain and providing support.
