In human gait analysis studies, the entire foot is typically modeled as a single rigid-body
segment; however, this neglects power generated/absorbed within the foot. Here we show …

Muscle–tendon units about the ankle joint generate a burst of positive power during the step-
to-step transition in human walking, termed ankle push-off, but there is no scientific …

Robotic prostheses have the potential to significantly improve mobility for people with lower-
limb amputation. Humans exhibit complex responses to mechanical interactions with these …

Unilateral lower-limb amputees exhibit asymmetry in many gait features, such as ground
force, step time, step length, and joint mechanics. Although these asymmetries result from …

This paper aims to develop a knowledge base and identify the promising research pathways
toward designing lower limb prostheses for optimal biomechanical and clinical outcomes. It …

Amputees using passive ankle-foot prostheses tend to expend more metabolic energy
during walking than non-amputees, and reducing this cost has been a central motivation for …

Lower limb loss is a major insult to the body's nervous and musculoskeletal systems.
Despite technological advances in prosthesis design, artificial limbs are not yet integrated …

Lower-limb wearable robotic devices can improve clinical gait and reduce energetic
demand in healthy populations. To help enable real-world use, we sought to examine how …

The elastic stretch-shortening cycle of the Achilles tendon during walking can reduce the
active work demands on the plantarflexor muscles in series. However, this does not explain …

Background Enhancing the quality of life of people with a lower limb amputation is critical in
prosthetic development and rehabilitation. Yet, no overview is available concerning the …
