The Surf Leg Prosthetic project team in conjunction with QL+ and Operation Surf designed a transtibial prosthetic to be used for surfing. The senior project team focused on the missions of QL+ and Operation Surf as they went through the design process during the 2018-2019 academic year. The problem solved was that a standard prosthetic for a transtibial amputee does not provide the flexibility in enough degrees of freedom for a user to squat and balance on a surfboard. The goal of this project was to create a device specifically designed to improve the user’s balance and control while surfing. The device was designed with the idea that it could be used by anyone in need of a lower leg prosthetic for surfing at the Operation Surf events, while focusing on a specific user, Kyle Kelly, for testing and dimensions. The lower leg prosthetic fits onto the user’s already existing socket. The prosthetic is waterproof and improves upon already existing options for amputees by increasing the user’s ankle mobility and angles of the foot for the purposes of surfing.
