Practical application research on high-stability prosthetic knee joints for frozen roads

Abstract

When frozen, roads are very easy to slip on, requiring extreme care not to fall down. For individuals with prosthetic legs, the risk is higher due to an increase in the chances of their knees buckling. Therefore, standing phase stability and the ability to walk securely are absolutely essential in the knee joints of prosthetic legs. By utilizing a six-jointed link structure, we have developed a highly stable prosthetic knee joint. When the heel comes in contact with the ground, this newly developed knee joint flexes, increasing its stability. When the user senses danger, they can choose to lock the knee’s position by themselves.
