The H2 robotic exoskeleton for gait rehabilitation after stroke: early findings from a clinical study.
Journal of neuroengineering and rehabilitation
Jun 17, 2015
BACKGROUND: Stroke significantly affects thousands of individuals annually, leading to considerable physical impairment and functional disability. Gait is one of the most important activities of daily living affected in stroke survivors. Recent techn...
Design and Fabrication of a Six Degree-of-Freedom Open Source Hand.
IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society
Jun 15, 2015
Currently, most externally powered prostheses are controlled using electromyography (or EMG), which is the measure of the electrical signals that are produced when voluntary muscle is contracted. One of the major problems is that there are a limited ...
Development of novel 3D-printed robotic prosthetic for transradial amputees.
Prosthetics and orthotics international
May 1, 2015
BACKGROUND AND AIM: Upper extremity myoelectric prostheses are expensive. The Robohand demonstrated that three-dimensional printing reduces the cost of a prosthetic extremity. The goal of this project was to develop a novel, inexpensive three-dimensi...
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
Apr 30, 2015
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...
The influence of push-off timing in a robotic ankle-foot prosthesis on the energetics and mechanics of walking.
Journal of neuroengineering and rehabilitation
Feb 22, 2015
BACKGROUND: Robotic ankle-foot prostheses that provide net positive push-off work can reduce the metabolic rate of walking for individuals with amputation, but benefits might be sensitive to push-off timing. Simple walking models suggest that preempt...
A Novel Interactive Exoskeletal Robot for Overground Locomotion Studies in Rats.
IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society
Feb 5, 2015
This paper introduces a newly developed apparatus, Iron Rat, for locomotion research in rodents. Its main purpose is to allow maximal freedom of voluntary overground movement of the animal while providing forceful interaction to the hindlimbs. Advant...
Ten-dimensional anthropomorphic arm control in a human brain-machine interface: difficulties, solutions, and limitations.
Journal of neural engineering
Dec 16, 2014
OBJECTIVE: In a previous study we demonstrated continuous translation, orientation and one-dimensional grasping control of a prosthetic limb (seven degrees of freedom) by a human subject with tetraplegia using a brain-machine interface (BMI). The cur...
An assistive control approach for a lower-limb exoskeleton to facilitate recovery of walking following stroke.
IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society
Aug 12, 2014
This paper presents a control approach for a lower-limb exoskeleton intended to facilitate recovery of walking in individuals with lower-extremity hemiparesis after stroke. The authors hypothesize that such recovery is facilitated by allowing the pat...
A powered prosthetic intervention for bilateral transfemoral amputees.
IEEE transactions on bio-medical engineering
Jul 2, 2014
This paper presents the design and validation of a control system for a pair of powered knee and ankle prostheses to be used as a prosthetic intervention for bilateral transfemoral amputees. The control system leverages communication between the pros...
Machine Learning-Based Rapid Prediction of Torsional Performance of Personalized Peripheral Artery Stent.
International journal for numerical methods in biomedical engineering
Mar 1, 2025
The complex mechanical environment of peripheral arteries makes stents with poor torsional performance more prone to fracture, and stent fracture is considered a precursor to in-stent restenosis (ISR). Therefore, studying the torsional performance of...
