Ambulation with existing prostheses is extremely difficult for individuals with bilateral above-
knee amputations. Commonly prescribed prostheses are passive devices that cannot …

Powered ankle-foot prostheses offer the potential to emulate natural locomotion dynamics,
thereby addressing the issues related to uneven gait and insufficient propulsion typically …

Across different fields within robotics, there is a great need for lightweight, efficient actuators
with human-like performance. Linkage-based passive variable transmissions and torque …

Most biomechanical research has focused on level-ground walking giving less attention to
other conditions. As a result, most lower limb prosthesis studies have focused on sagittal …

The toe joint has been studied since it plays a critical role in human ambulation, such as
stability, energy storage and propulsion. Despite its critical role, only a few studies have …

Ambulation in everyday life requires walking at variable speeds, variable inclines, and
variable terrains. Powered prostheses aim to provide this adaptability through control of the …

This study proposes a novel ankle-foot prosthesis design with an active
metatarsophalangeal joint (MTPJ), which effectively mimicking the toe-gripping function of a …

Abstract In the United States, above-knee amputation affects the mobility and quality of life of
more than 600,000 people. These individuals have a significant mobility reduction partly due …

ABSTRACT this study, a bio-inspired design was introduced to fabricate an inexpensive
robotic prosthetic foot. Toe joints and torsion springs improve gait stability and propulsion …

The quality of life and ambulation ability of over 1 million people is affected by lower-limb
amputation in the United States. Currently available passive prostheses use springs and …
