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 …

The concept of frailty syndrome (FS) was first described in the scientific literature three
decades ago. For a very long time, we understood it as a geriatric problem, recently …

Powered knee and ankle prostheses can perform a limited number of discrete ambulation
tasks. This is largely due to their control architecture, which uses a finite-state machine to …

Robotic prostheses and powered exoskeletons are novel assistive robotic devices for
modern medicine. Muscle activity sensing plays an important role in controlling assistive …

Goal: To provide an overview of control strategies in commercial and research
microprocessor-controlled prosthetic knees (MPKs). Methods: Five commercially available …

Although there has been recent progress in control of multi-joint prosthetic legs for rhythmic
tasks such as walking, control of these systems for non-rhythmic motions and general real …

Although emerging powered prostheses can enable people with lower-limb amputation to
walk and climb stairs over different task conditions (eg, speeds and inclines), the control …

Powered prosthetic legs can improve the quality of life for people with transfemoral
amputations by providing net positive work at the knee and ankle, reducing the effort …

With advances in robotic prostheses, rese-archers attempt to improve amputee's gait
performance (eg, gait symmetry) beyond restoring normative knee kinematics/kinetics. Yet …

Transfemoral amputee gait often exhibits compensations due to the lack of ankle push-off
power and control over swing foot position using passive prostheses. Powered prostheses …
