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

Terrain detection systems have been developed for a large body of applications. For
instance, a bionic leg prosthesis would have to adapt its behavior as a function of the terrain …

The wearable lower limb exoskeleton is a typical human-in-loop human–robot coupled
system, which conducts natural and close cooperation with the human by recognizing …

Robotic prostheses deliver greater function than passive prostheses, but we face the
challenge of tuning a large number of control parameters in order to personalize the device …

Visual information is indispensable to human locomotion in complex environments.
Although amputees can perceive the environmental information by eyes, they cannot …

Powered lower limb prostheses have potential to improve the quality of life of individuals
with amputations by enabling all daily activities. However, seamless ambulation mode …

This paper presents a novel methodology for estimating the gait phase of human walking
through a simple sensory apparatus. Three subsystems are combined: a primary phase …

Real-time recognition of locomotion-related activities is a fundamental skill that a controller
of lower limb wearable robots should possess. Subject-specific training and reliance on …

Objective: Walking task prediction in powered leg prostheses is an important problem in the
development of biomimetic prosthesis controllers. This paper proposes a novel method to …

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