While a healthy human walks, his or her legs mutually perform good repeatability
with high accuracy. This provides an esthetical movement and balance. People
with above knee prosthesis want to perform walking as esthetical as a healthy
human. Therefore, to achieve a healthy walking, the above knee prosthesis must
provide a good stiffness performance. Especially stiffness values are required
when adding a second axis movement to the ankle for eversion and inversion. In
this paper, stiffness analysis of above-knee prosthesis is presented. The
translational displacement of above knee prosthesis is obtained when the
prosthesis is subjected to the external forces. Knowing stiffness values of the
above knee prosthesis, designers can compute prosthesis parameters such as
ergonomic structure, height, and weight and energy consumption.
