Once-per-step control of ankle-foot prosthesis push-off work reduces effort associated with balance during walking.

Journal of neuroengineering and rehabilitation
BACKGROUND: Individuals with below-knee amputation have more difficulty balancing during walking, yet few studies have explored balance enhancement through active prosthesis control. We previously used a dynamical model to show that prosthetic ankle ...

Variable Cadence Walking and Ground Adaptive Standing With a Powered Ankle Prosthesis.

IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society
This paper describes a control approach that provides walking and standing functionality for a powered ankle prosthesis, and demonstrates the efficacy of the approach in experiments with a unilateral transtibial amputee subject. Both controllers inco...

What is it like to walk with the help of a robot? Children's perspectives on robotic gait training technology.

Disability and rehabilitation
PURPOSE: Robotic gait training is an emerging intervention that holds great therapeutic promise in the rehabilitation of children with neuromotor disorders such as cerebral palsy (CP). Little is known about children and parents' views on this new tec...

Robot-assisted gait training might be beneficial for more severely affected children with cerebral palsy.

Developmental neurorehabilitation
PURPOSE: Robot-assisted gait training (RAGT) can complement conventional therapies in children with cerebral palsy. We investigated changes in walking-related outcomes between children with different Gross Motor Function Classification System (GMFCS)...

Multibody system dynamics for bio-inspired locomotion: from geometric structures to computational aspects.

Bioinspiration & biomimetics
This article presents a set of generic tools for multibody system dynamics devoted to the study of bio-inspired locomotion in robotics. First, archetypal examples from the field of bio-inspired robot locomotion are presented to prepare the ground for...

Goal-directed multimodal locomotion through coupling between mechanical and attractor selection dynamics.

Bioinspiration & biomimetics
One of the most significant challenges in bio-inspired robotics is how to realize and take advantage of multimodal locomotion, which may help robots perform a variety of tasks adaptively in different environments. In order to address the challenge pr...

Quadrupedal galloping control for a wide range of speed via vertical impulse scaling.

Bioinspiration & biomimetics
This paper presents a bio-inspired quadruped controller that allows variable-speed galloping. The controller design is inspired by observations from biological runners. Quadrupedal animals increase the vertical impulse that is generated by ground rea...

Facilitatory effects of anti-spastic medication on robotic locomotor training in people with chronic incomplete spinal cord injury.

Journal of neuroengineering and rehabilitation
BACKGROUND: The objective of this study was to investigate whether an anti-spasticity medication can facilitate the effects of robotic locomotor treadmill training (LTT) to improve gait function in people with incomplete spinal cord injury (SCI).

Lokomat training in vascular dementia: motor improvement and beyond!

Aging clinical and experimental research
Vascular dementia (VaD) is a general term describing problems with reasoning, planning, judgment, memory, and other thought processes caused by brain damage from impaired blood flow to the brain. Cognitive rehabilitation and physical therapy are the ...
