Effect of Asymmetric, Charge Balanced Stimuli on Elicited Compound Neural Action Potentials

Abstract

Whether via cuff or intrafascicular electrode, peripheral neural stimulations often rely on symmetric, charge balanced paradigms. To date, few investigations have been carried out which systematically decompose the features of a stimulus waveform. Factors such as pulse-width, amplitude, and the timing with which they are presented may have significant effects on the quality of the stimuli. This work seeks to fill this gap in knowledge and share insight into how selection of electrical stimuli may affect the resultant neural activation in peripheral nerves. In particular, we found that, although there is some variance, over the parameter range tested there was not a significant effect on neural fiber recruitment percent due to waveform selection.
