Electrochemical Burns: A Risk With Myoelectric Prostheses

Abstract

The authors describe their experience myoelectric prostheses, with incidents of minor trauma, to users of which is thought to be associated with electrochemical bums arising from a dc potential existing between electrodes. These incidents have occurred over the period 1968 - 1996, in Winnipeg, Toronto and Fredericton. A possible mechanism is suggested for electrochemical burns where a dc potential of one volt or more exists. Finally, recommendations are made for increased vigilance concerning this possible problem.
