Bracing refers to the use of supportive devices or materials to stabilize or strengthen a structure, body part, or object. In construction, braces are often used to reinforce walls or roofs, preventing them from collapsing or swaying. In medicine, braces can support weak or injured limbs, helping to maintain proper alignment and function. In sports, athletes may use braces to protect joints, such as knees or ankles, from injury during physical activity. These devices can be made from various materials, including metal, plastic, or fabric, and are designed to provide comfort while ensuring stability and support.
