Prosthetic limbs are artificial devices designed to replace missing arms or legs. They help individuals regain mobility and perform daily activities. These devices can be customized to fit the user's body and needs, often using advanced materials and technology for comfort and functionality. Modern prosthetics may include features like electronic components that allow for movement control, making them more responsive. Some prosthetic limbs are designed for specific activities, such as sports or running, enhancing the user's quality of life. Advances in biomechanics and robotics continue to improve the effectiveness of these devices.
