A back brace is a supportive device worn around the torso to help stabilize the spine and reduce pain. It is commonly used for conditions like lower back pain, scoliosis, or after surgery. The brace limits movement, which can help prevent further injury and promote healing. Back braces come in various styles, including rigid and flexible types. They are often made from materials like fabric, plastic, or metal. While they can provide relief, it's important to use them under the guidance of a healthcare professional, such as a physiotherapist or orthopedic doctor, to ensure proper fit and effectiveness.
