Braces and supports are devices designed to stabilize, protect, or improve the function of a body part, often used in rehabilitation or injury prevention. They can be made from various materials, including plastic, metal, and fabric, and are commonly used for joints like the knee, ankle, or wrist. These devices help reduce pain, limit movement, and provide support during physical activities. They are often recommended by healthcare professionals, such as orthopedic doctors or physical therapists, to aid recovery from injuries or surgeries and to manage chronic conditions like arthritis.
