Abstract
The desirable balanced-position of a prosthetic ankle joint is different during level walking and slop walking, and as most of the existing prosthetic ankle joint are designed for level walking and those supposed to be applied to slop walking are also not satisfying, it is difficult for prosthetic ankle joint users to walk as smoothly as normal persons do during slop walking. In this paper, a prototype of below-knee prosthesis that the balanced-position of the prosthetic ankle joint is adjustable to the inclination of a slope while walking is introduced, and as the device is only at work during the swing phase, the consumption of energy is small. In addition, the evaluation on the function and effectiveness of the device was done by walking experiments.
