Background: For transtibial amputees, the use of a transtibial prosthesis has an impact on
balance during daily activities (Wang et al., 2015). Apart from the prosthesis which affect …

Background: Lower limb amputation with or without the use of a prosthesis has an impact on
energy consumption/needs for ambulances. There are studies that say the results of the …

Previous studies have shown that the effective rocker shape of the physiologic ankle-foot
system during standing and fore-aft swaying is much flatter than that used during walking …

The Shape&Roll prosthetic foot was used to examine the effect of roll-over shape arc length
on the gait of 14 unilateral trans-tibial prosthesis users. Simple modifications to the …

Prosthetic foot stiffness is typically prescribed based on a person's weight and activity level,
which may not be optimal for a particular patient. This study investigates how different …

The biological ankle dorsiflexes several degrees during swing to provide adequate
clearance between the foot and ground, but conventional energy storage and return (ESR) …

In able-bodied individuals, the ankle joint functions to provide shock absorption, aid in foot
clearance during the swing phase, and provides a rocker mechanism during stance phase …

This study accesses the effects of shoe heel heights on loading, muscle activity, and plantar
foot pressure of trans-tibial amputees during standing. Five male subjects with unilateral …

Powered prosthetic feet (PPF) are designed to provide transtibial amputees (TTA) with active
propulsion and range of motion similar to that of the biological limb. Previous studies have …

The human ankle-foot system conforms to a circular effective rocker shape for walking, but to
a much flatter effective shape for standing and swaying. Many persons with lower limb …
