ALERT: This system is being upgraded on Tuesday December 12. It will not be available
for use for several hours that day while the upgrade is in progress. Deposits to DukeSpace
will be disabled on Monday December 11, so no new items are to be added to the repository
while the upgrade is in progress. Everything should be back to normal by the end of
day, December 12.

The War Amputations Of Canada: Addressing The Needs Of Canadian Amputees
(1999)I lost a leg to cancer at the age of 13. I became a member of The War Amps Child Amputee Program, or CHAMP as it is better known, shortly theteafter. For the last 10 years I have worked with the War Amps and am presently ... -
The use of the Hilbert transforra in EMG Analysis
(1999)The Fourier transform has traditionally been used for the detailed analysis of EMG signals. This has yielded many useful results, none more so than the descriptions of the energy produced at differing frequencies. This has ... -
The Use of Fuzzy Logic In the Processing Of Myoelectric Signals
(1999)This paper describes the use of Fuzzy logic for the processing of EMG signals. This can increase the recognition rate and significantly reduce the number of computations required to generate an output. The initial placement ... -
The Development Of An Advanced Multi-Axis Myo-Prosthesis And Controller
(1999)Commercial myo-electrically controlled prostheses are currently single degree of fieedom devices with highly restrictive function. These artificial hands warrant high grip forces due to their planar pincer movement to ensure ... -
Quantifying Impaired Hand Function In The Clinical Environment
(1999)The Southampton Hand Assessment Procedure (SHAP) has been developed specifically to enable the broadbased evaluation of hand function irrespective of the disability, thereby allowing assessment of both natural and prosthetic ... -
Prosthetic Management Of A Child With A Phocomelic Deficiency
(1999)The subject of this case study is an 8 year old girl who has a phocomelic deficiency of her left uppet extremity. Her phocomelic hand consists of 3 digits including a thumb and has limited strength and range of motion. She ... -
Programmable Control: Clinical Experience At Bloorview MacMillan Centre
(1999)Advances in microprocessor technology in recent years have led to the introduction of programmable control systems for powered prosthetics. These systems allow amputees to try a variety of control schemes and choose the ... -
New Clinically-Useful Control Strategies Made Possible By The Varigrip II Multi-Device Controller
(1999)The VariGrip II Controller can operate up to three variable speed motors. For inputs it uses two, three, or four variable voltages and one on-off switch. This makes a large number of control strategies available, but not ... -
Optimal Fixed Wrist Alignment For Below-Elbow, Powered, Prosthetic Hands
(1999)The typical prosthetic wrist has a limited range of motion. Although a rotating device may be used for pronation/supination, flexion/extension and radial/ulnar deviation generally are set in a fixed alignment by the prosthetist. ... -
Natural Control Of Key Grip And Precision Grip Movements For A Myoelectric Prostheses
(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 ... -
Magnetic Resonance Imaging of Congenitally Deficient Upper Limbs
(1999)Knowledge of the anatomic location, size, and contractility of muscles within a person's congenitally deficient upper limb is useful in prescribing and fitting a myoelectric prosthesis. In 1998, at University of Texas' Hermann ... -
Microframe Interface Design For High Level Myoelectr1c Prostheses
(1999)The provision of a myoelectric prosthesis for high level upper extremity amputees requires consideration of a myriad of factors. Although state-of-the-art componentty can dramatically effect the outcome, other factors left ... -
Low Level Response Of Bock And Steeper Electrodes
(1999)For many years myoelectric fittings have been limited by the need for signals of at least 2011V when using convenient in-socket myoelectrode-amplifiers. With the introduction of the Bloorview-MacMillan MyoMicro technology, ... -
Forequarter Prosthesis With Interchangeable Elbow, Forearm, And Hand
(1999)Fitting of individuals with forequarter amputations is often a challenging and fruitless effort. In order to provide optimum function for the patient, it is necessary to fit these individuals with either externally powered ... -
Fitting The Humeral Level Brachial Plexus Amputee With Externally Powered Myoelectric Control
(1999)Brachial plexus injuries present unique challenges to both the patient and prosthetist, The brachial plexus injury can be classified in many categories: complete or incomplete lesion, with either an intact or amputated limb ...
