Microprocessor-controlled knees (MPKs) and purely active (e.g. motor-powered) prosthetic knees have several limitations that affect their versatility. MPKs lack the support needed for power-intensive activities, while active prostheses fall short in terms of quietness, naturalness, and lightness. Adopting a user-centered design approach for transfemoral amputees, we identified the requirements for an ideal knee prosthesis. The findings from this initial research were then used to develop a design concept for a semi-powered knee prosthesis named Unico. This paper discusses these two initial development phases.

摘要

Microprocessor-controlled knees (MPKs) and purely active (e.g. motor-powered) prosthetic knees have several limitations that affect their versatility. MPKs lack the support needed for power-intensive activities, while active prostheses fall short in terms of quietness, naturalness, and lightness. Adopting a user-centered design approach for transfemoral amputees, we identified the requirements for an ideal knee prosthesis. The findings from this initial research were then used to develop a design concept for a semi-powered knee prosthesis named Unico. This paper discusses these two initial development phases.
