This paper presents a review on design issues and solutions found in active lower limb
prostheses. This review is based on a systematic literature search with a methodical search …

This review paper provides a synthetic yet critical overview of the key biomechanical
principles of human bipedal walking and their current implementation in robotic platforms …

Ferris AE, Aldridge JM, Rábago CA, Wilken JM. Evaluation of a powered ankle-foot
prosthetic system during walking. OBJECTIVE: To determine whether a powered ankle-foot …

Background Current prosthetic ankle joints are designed either for walking or for running. In
order to mimic the capabilities of an able-bodied, a powered prosthetic ankle for walking and …

Human upright locomotion is a complex behavior depending on manifold requirements.
Bones, muscles, cartilage and tendons provide mechanical infrastructure. Central nervous …

Purpose: Amputation results in reduced mobility and contributes to reduced quality of life.
The increased metabolic cost of ambulation has been suggested as an important contributor …

Researchers are currently making progress in unifying the entire gait cycle of powered
prostheses by using a human-inspired phase variable, but constructing a robust phase …

Objective Unilateral trans-tibial amputation signifies a challenge to locomotion. Prosthetic
ankle-foot units are developed to mimic the missing biological system which adapts push-off …

Background: Hundreds of investigations examining biomechanical outcomes of various
prostheses have been completed, but one question remains unanswered: how much time …

People with major limb amputations are severely impaired when it comes to activity, body
structure and function, as well as participation. Demographic statistics predict a dramatic …
