Existing controllers for robotic powered prostheses regulate the prosthesis speed, timing,
and energy generation using predefined position or torque trajectories. This approach …

Background After above-knee amputation, the missing biological knee and ankle are
replaced with passive prosthetic devices. Passive prostheses are able to dissipate limited …

A prosthetic knee is designed to replace the functionality of an anatomical knee in
transfemoral amputees. The purpose of a prosthetic knee is to restore mobility and …

This study aims to develop a magnetorheological (MR) damper for semi-active knee
prostheses to restore the walking ability of transfemoral amputees. The core dimensions of …

Transfemoral amputees rely on prosthetic devices to restore their mobility and maintain their
independence. However, the design and performance of these devices can significantly …

BACKGROUND: Due to low friction, passive mechanical prostheses move compliantly
followed by the stump and are used widely. Advanced semi-active prostheses can both …

This work presents the design, development and validation of a partially powered knee
prosthesis that enhances key features of energetically passive microprocessor-controlled …

Robotic prostheses involve the utilization of artificial limbs designed for optimal power
efficiency, significantly enhancing users' mobility and independence. The primary focus in …

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

Over the last decades, active knee prostheses demonstrated their ability to support most
daily-life locomotion tasks for transfemoral amputees. However, passive devices are still …
