A prosthetic limb is an artificial device designed to replace a missing or amputated arm or leg. These devices help individuals regain mobility and perform daily activities. Prosthetic limbs can be customized to fit the user's body and may include advanced technology, such as sensors and motors, to enhance functionality. Modern prosthetics can be made from various materials, including plastic, carbon fiber, and metal. They can be classified into different types, such as transfemoral (above the knee) and transtibial (below the knee) prosthetics. The development of prosthetic limbs has significantly improved the quality of life for many people with limb loss.
