Motor Control Processes When Learning To Use A Prosthetic Device

Bongers, Raoul M.; Bouwsema, Hanneke; van der Sluis, Corry K. (Myoelectric Symposium, 2011)

Prosthetic devices are designed to increase the action possibilities of an amputee. Appropriate actions with upper-extremity prostheses are only possible when these devices can be controlled dexterously. Importantly, the ...
Movement onset detection in various positions for state-based myo-control scheme

Lorrain, T.; Niazi, I. K.; Jiang, N.; Farina, D. (Myoelectric Symposium, 2011)

Myoelectric prostheses offer great potential of rehabilitation for amputees. However, a main drawback toward this achievement lies in the control algorithms, which are unable to reliably translate the user’s intention to ...
Multi-articulating Hands & Fingers – Technical Strategies for Improved Patient Function and Myoelectric Uptake

Newman, Phil (Myoelectric Symposium, 2008)

Since the commercial release of the i-LIMB Hand in September 2007, and the subsequent R&D release of ProDigits for partial hand users, there has been much interest from clinical professionals – to date (18 March 2008), ...
MULTIFUNCTION PROSTHESIS CONTROL USING IMPLANTED MYOELECTRIC SENSORS (IMES)

Schorsch, Jack F.; Maas, Huub; Troyk, Phil R.; DeMichele, Glen A.; Kerns, Douglas A.; Weir, Richard F. (Myoelectric Symposium, 2008)

Persons with recent hand amputations expect modern hand prostheses to function like intact hands. Current stateof- the-art electric prosthetic hands are generally single degree-of-freedom (opening and closing) devices ...
MULTI-FUNCTION SWITCHING OPTION FOR THE HIGHER LEVEL UPPER LIMB AMPUTEE

Mikosz, Matthew J. (Myoelectric Symposium, 2005)

The purpose of this article is to describe an alternative switching option for the higher-level upper limb amputee. Currently available body powered switches allow for only one function which can become quite cumbersome ...
Multimodal Input Device With SEMG And Contact Force Sensors

Stavdahl, Øyvind; Kyberd, Peter J.; Magne, Tordis; Ottermo, Maria V.; Mugaas, Terje (Myoelectric Symposium, 2011)

In myoelectric prostheses, movement artifacts are known to impair control performance. This study relates to a novel sensor which measures surface electromyograms (SEMG) as well as contact force at the electrode-skin ...
MULTIPLE IMPAIRMENTS OVERCOME BY SOCKET DESIGN & APPROPRIATE COMPONENTS

Mandacina, Stephen; Lenzini, Gary (Myoelectric Symposium, 2005)

The success of prosthetic rehabilitation involves a number of facets including optimum therapy, appropriate components, interdisciplinary network, patient motivation, and a good fitting socket. All of these facets get ...
A MYOELECTRICALLY CONTROLLED PROSTHETIC HAND FOR TRANSMETACARPAL AMPUTATIONS.

Weir, Richard F.; Grahn, Edward C. (Myoelectric Symposium, 2002)

We have developed a new externally-powered, myoelectrically controlled partial hand prosthesis that is suitable for fitting those persons with amputations at or more proximal to the level of the metacarpophalangeal (MCP) ...
Myoelectric Camp: An Interdisclplinary Approach To Fitting Myoelectric Prostheses

Lombardo, Janet R. (Myoelectric Symposium, 1993)

The Philadelphia Unit of Shriners Hospitals has developed an interdisciplinary plan forproviding 5-10 year olds with a comprehensive introduction to myoelectric fittings. The program utilizes a summer camp format for service ...
Myoelectric Control Of A Powered Transfemoral Prosthesis During Non-Weight-Bearing Activities

Hargrove, Levi; Simon, Ann M.; Finucane, Suzanne B.; Lipschutz, Robert D. (Myoelectric Symposium, 2011)

Lower limb prostheses have traditionally been mechanically passive devices without electronic control systems. Microprocessor-controlled passive and powered devices have recently received much interest from the clinical ...
Myoelectric Control Of Prostheses: A Brief History

Scott, R. N. (Myoelectric Symposium, 1992)
Myoelectric Control Of The Muscle Electrostimulation

Bernstein, V. M.; Slavutsky, J. L.; Farber, B. S. (Myoelectric Symposium, 1993)
Myoelectric Control Using Modulated Minimum Jerk Movement

Russell, Donald L. (Myoelectric Symposium, 1994)

A new control system for elbow prostheses is proposed. The system would use myoelecuic activity (MEA) meastuements to modulate the execution of a maxirnally smooth, minimum jerk movement A prosthesis controller may extract ...
MYOELECTRIC ELECTRODE AMPLIFIERS: REJECTION OF UNWANTED COMMON MODE SIGNALS

Poulton, Adrian (Myoelectric Symposium, 2008)

This investigation was prompted by a chance observation during trials of the ToMPAW arm system [1]. The arm has a carbon fibre structure which, although not directly connected to the system electronics, can act as an ...
Myoelectric Prostheses with Sensorial Feedback

Rios Poveda, Alvaro (Myoelectric Symposium, 2002)

A design of a control system for myoelectric prostheses is shown based on a microcontroller that can give the possibility for the amputated patient to replace the pressure perception. In addition this design will permit ...
Myoelectric Signal Classification Using A Finite Impulse Response Neural Network

Englehart, K. B.; Hudgins, B. S.; Stevenson, M.; Parker, P. A. (Myoelectric Symposium, 1994)

Recent work by Hudgins has proposed a neural network-based approach to classifying themyoelectric signal (MES) elicited at the onset of movement of the upper limb. A standard feed forward artificial network was trained ...
Myoelectrode Lift-Off Detection

Smitts, Matthijs (Myoelectric Symposium, 1997)
Natural Control Of Key Grip And Precision Grip Movements For A Myoelectric Prostheses

Santa-Cruz, M. C.; Riso, R. R.; Lange, B.; Sepulveda, F. (Myoelectric Symposium, 1999)

Hand prosthesis function is augmented when the user canemploy lateral grasp as well as traditional palmer grasp. Our goal in this investigation was to enable the below-elbow (BE) prostheses user to switch between and use ...
Neurofuzzy Logic as a Control Algorithm for an Externally Powered Multifunctional Hand Prosthesis

Ajiboye, Abidemi Bolu; Weir, Richard F.; Heckathorne, Craig W.; Childress, Dudley S. (Myoelectric Symposium, 2002)
