The Optimal Controller Delay for Myoelectric Prostheses

Analysis Window Induced Controller Delay for Multifunctional Prostheses

INTRODUCTION AND VARIABLE DEFINITION: Many upper-limb, multifunctional prosthesis controllers analyze fixed segments of EMG data collected from the residual musculature in an attempt to discern the intended movement of the user. However, many researchers have designed controllers with little or no regard for the delay the controller will introduce when operated in real-time. If the delay is too...

Automatic tuning of myoelectric prostheses.

This paper is concerned with the development of a software package for the automatic tuning of myoelectric prostheses. The package core consists of Fuzzy Logic Expert Systems (FLES) that embody skilled operator heuristics in the tuning of prosthesis control parameters. The prosthesis system is an artificial arm-hand system developed at the National Institute of Accidents at Work (INAIL) laborat...

Myoelectric Control of Prostheses and Orthoses

Intelligent multifunction myoelectric control of hand prostheses.

Intuitive myoelectric prosthesis control is difficult to achieve due to the absence of proprioceptive feedback, which forces the user to monitor grip pressure by visual information. Existing myoelectric hand prostheses form a single degree of freedom pincer motion that inhibits the stable prehension of a range of objects. Multi-axis hands may address this lack of functionality, but as with mult...

Electrochemical Burns: a Risk with Myoelectric Prostheses

ELECTROCHEMICAL BURNS: A RISK WITH MYOELECTRIC PROSTHESES Bob Scott, Bob Caldwell, and Greg Bush University of New Brunswick Institute of Biomedical Engineering Fredericton NB Canada ABS TRACT The authors describe their experience with incidents of minor trauma, to users of myoelectric prostheses, which is thought to be associated with electrochemical bums arising from a dc potential existing b...
