Rehabilitation engineering involves developing technology-driven solutions to enhance the lives of people with physical limitations. This field integrates engineering principles with healthcare to create adaptive devices, prosthetics, and robotics that improve functional independence. By tailoring devices to meet individual needs, rehabilitation engineers help patients regain mobility, dexterity, and confidence. Advanced rehabilitation engineering incorporates AI, robotics, and wearable sensors, fostering innovations like exoskeletons for gait training and smart prosthetics that respond to muscle signals. These technologies bridge the gap between injury and active living, supporting personalized therapy plans. The ultimate goal is to provide accessible, user-friendly devices that make rehabilitation effective and life-changing.
