A neck brace, also known as a cervical collar, is a medical device designed to support and immobilize the neck. It is commonly used following a neck injury, surgery, or to treat chronic neck pain. The brace helps limit neck movement, thereby reducing pain and promoting healing by keeping the neck in a stable position. Neck braces are made from various materials, ranging from soft foam to rigid plastic, depending on the level of support required. Soft collars offer moderate support and are typically used for minor injuries or pain relief, while rigid braces are used for more severe injuries or post-surgical recovery. Proper fitting and usage under medical supervision are crucial to ensure effective treatment and avoid complications.
