Depth Sensing for Improved Control of Lower Limb Prostheses.
IEEE transactions on bio-medical engineering
Jun 22, 2015
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 recognition is necessary to achieve this goal and is not yet a clinical re...
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 ...
Locomotor Adaptation by Transtibial Amputees Walking With an Experimental Powered Prosthesis Under Continuous Myoelectric Control.
IEEE transactions on neural systems and rehabilitation engineering : a publication of the IEEE Engineering in Medicine and Biology Society
Jun 4, 2015
Lower limb amputees can use electrical activity from their residual muscles for myoelectric control of a powered prosthesis. The most common approach for myoelectric control is a finite state controller that identifies behavioral states and discrete ...
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...
Once-per-step control of ankle-foot prosthesis push-off work reduces effort associated with balance during walking.
Journal of neuroengineering and rehabilitation
May 1, 2015
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
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...
Multiclassifier system with hybrid learning applied to the control of bioprosthetic hand.
Computers in biology and medicine
Apr 25, 2015
In this paper the problem of recognition of the intended hand movements for the control of bio-prosthetic hand is addressed. The proposed method is based on recognition of electromiographic (EMG) and mechanomiographic (MMG) biosignals using a multicl...
Adaptive myoelectric pattern recognition toward improved multifunctional prosthesis control.
Medical engineering & physics
Mar 3, 2015
The non-stationary property of electromyography (EMG) signals in real life settings usually hinders the clinical application of the myoelectric pattern recognition for prosthesis control. The classical EMG pattern recognition approach consists of two...
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...
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...
