Low Level Response Of Bock And Steeper Electrodes

Abstract

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, the controller is able to further amplify the patient myosignal. To evaluate the Bock 13E125 and Steeper Electrodes for providing suitable signals for control in the region below 20uV, both electrodes were tested at each gain setting. The Bock electrode gives the best signals in the 1 to 5uV range while the Steeper electrode is less sensitive. With suitable downstream amplification, both electrodes will provide proportional control with signals of 0-10uV.
