THE EFFECT OF CONTROLLER DELAY ON BOX AND BLOCK TEST PERFORMANCE

Farrell, Todd R.; Weir, Richard F.; Heckathorne, Craig W. (Myoelectric Symposium, 2005)

Multifunctional prosthesis controllers have shown higher classification accuracies when EMG feature extraction and pattern recognition are performed on time windows of longer duration [1] (see figure 1). However, there is ...
EVALUATION OF A PROTOTYPE ELECTRIC-POWERED PARTIAL-HAND PROSTHESIS

Heckathorne, Craig W.; Weir, Richard F. (Myoelectric Symposium, 2005)

A prototype partial hand mechanism has been developed for fittings at the trans-metacarpal level. Subjects selected for evaluation of the prototype device have absence of all fingers of the affected hand, all or some portion ...
Experience With The Rimjet Locking Humeral Rotator

Uellendahl, Jack E.; Heckathorne, Craig W. (Myoelectric Symposium, 1999)
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)

We propose an algorithm based upon neurofuzzy technology. We believe that because of the inherent “fuzziness” of human activity, a control algorithm based on fuzzy logic may have advantages for multifunctional prosthesis ...
The Prosthetics Needs Of Farmers And Ranchers With Upper-Limb Amputations

Heckathorne, Craig W.; Waldera, Kathy (Myoelectric Symposium, 2011)

Farming and ranching are among the most hazardous occupations in the United States with many non-fatal accidents resulting in amputation. In addition, those who continue to farm using prostheses are at risk of secondary ...
REAL-TIME COMPUTER MODELING OF A PROSTHESIS CONTROLLER BASED ON EXTENDED PHYSIOLOGICAL PROPRIOCEPTION (EPP)

Farrell, Todd; Weir, Richard F.; Heckathorne, Craig W.; Childress, Dudley S. (Myoelectric Symposium, 2002)

Proprioception utilizes the physiological components of the nervous and musculoskeletal systems to allow an individual to sense the position of their limbs subconsciously. By providing a rigid connection to an object ...
Using Motion Analysis To Augment Upper-Limb Prosthetics Outcome Measures

Heckathorne, Craig W.; Stine, Rebecca (Myoelectric Symposium, 2011)

As upper-limb prosthetic systems have become more sophisticated in terms of actuation and control, greater importance is being placed on producing movements of both the prosthesis and the user that have a more physiologically ...
