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 …

With the increase in the elderly, stroke has become a common disease, often leading to
motor dysfunction and even permanent disability. Lower‐limb rehabilitation robots can help …

This paper presents the design and validation of a novel lower limb prosthesis called the
variable stiffness foot (VSF), designed to vary its forefoot stiffness in response to user activity …

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 …

Passive prosthetic feet struggle to reproduce the human biological ankle range of motion
and push-off. We propose the Hybrid-Hydraulic Ankle Prosthesis (H2AP), a prosthetic foot …

Background If a prosthetic foot creates resistance to forwards shank rotation as it deforms
during loading, it will exert a braking effect on centre of mass progression. The present study …

Background Walking down slopes and/or over uneven terrain is problematic for unilateral
trans-tibial amputees. Accordingly,'ankle'devices have been added to some dynamic …

Abstract Background Minimum Toe Clearance (MTC) is defined as the minimum vertical
distance between the lowest point under the front part of the foot and the ground, during mid …

Background Previous research has shown that use of a dynamic-response prosthetic foot
(DRF) that incorporates a small passive hydraulic ankle device (hy AF), provides certain …

Background Typical gait data collections consist of discrete walking trials where participants
are aware when data are being recorded. Anecdotally, some investigators have reported …
