The spine is a complex joint composed of vertebrae, discs, muscles, tendons, cartilage, ligaments and nerves. The body demands a lot from the back: maintenance of posture, performance of movements, protection of the spinal cord.
Back injuries often occur during sports and other physical activities as well. Contact sports can especially stress your back. Wearing a back brace can provide extra support to your lower back when participating in these activities and is the best way to prevent hurting your back.
