Design of the prosthetic knee component to assist stair ascending gait

For trans-femoral (TF) amputee, the prosthetic knee component performs important roles to assist the motion of prosthetic leg during gait. Even though the variety prosthetic knee component can perform variety functions, the stair ascending gait still be the challenge mode of gait for TF amputee as the unexpected environmental had to be faced daily. This study is aiming to establish the design of the prosthetic knee component to assist stair ascending gait and to provide the control device by the microcontroller. The device from this project will be later applied to the indicated subject to perform real stair ascending gait.
