A prosthetic arm is an artificial device designed to replace a missing or damaged arm. It helps individuals regain functionality and improve their quality of life. Prosthetic arms can be customized to fit the user's needs and may include features like grips, joints, and even electronic components for enhanced movement. These devices can be made from various materials, including plastic and metal, and are often lightweight for ease of use. Advances in technology have led to the development of myoelectric prosthetics, which use electrical signals from the user's muscles to control movement, providing a more natural experience.
