Lower-limb prostheses aim to restore ambulatory function for individuals with lower-limb
amputations. While the design of lower-limb prostheses is important, this paper focuses on …

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 …

Osteoarthritis (OA) is the most frequent cause of disability in the United States, with the
medial compartment of the knee being most commonly affected. The initiation and …

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 …

Background People with a lower-extremity amputation that use conventional passive-elastic
ankle-foot prostheses encounter a series of stress-related challenges during walking such …

Anatomically-relevant (AR) biomechanical models are traditionally used to quantify joint
powers and segmental energies of lower extremity structures during gait. While AR models …

Primary disabling conditions, such as amputation, not only limit mobility, but also predispose
individuals to secondary musculoskeletal impairments, such as osteoarthritis (OA) of the …

Individuals with unilateral below-knee amputation expend more energy than non-amputees
during walking and exhibit reduced push-off work and increased hip work in the affected …
