The number of patients with knee impairments caused by a stroke, spinal cord injury, post-
polio, injury, osteoarthritis, or other related diseases is increasing worldwide. Robotic …

Exoskeleton technology has made significant advances during the last decade, resulting in
a considerable variety of solutions for gait assistance and rehabilitation. The mechanical …

Lower extremity robotic exoskeletons (LEEX) can not only improve the ability of the human
body but also provide healing treatment for people with lower extremity dysfunction. There …

Medical and rehabilitation exoskeletons are being increasingly considered by therapists
when choosing a treatment for individuals affected by lower limb impairments. Although all …

We present a novel application of the variable stiffness actuator (VSA)-based assistance/
rehabilitation robot-featured impedance control using a cascaded position torque control …

Stroke may lead to considerable physical impairment and functional disability, which affects
walking ability. As a potential way to assist gaits, lower limb exoskeletons have been …

This work presents a reconfigurable variable stiffness actuator (RVSA) based on a rotational
spring mechanism (torsional spring) and a group of specially designed symmetrical S …

Background Despite a large increase in robotic exoskeleton research, there are few studies
that have examined human performance with different control strategies on the same …

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 …

This article proposes a lightweight variable stiffness actuator (LVSA) driven by a novel
mechanism with four sliders on a shared crank (FS2C). The FS2C mechanism allows the …
