Design and Construction of an Electrical Nerve Stimulator

Abstract

In previous work, the effect of pulse configuration on the compound muscle action potentials (CMAPs) during magnetic stimulation was examined. It was concluded that an alternative approach, electrical stimulation, was required to re-evaluate and confirm the findings. Accordingly, a special electrical stimulator capable of producing stimuli which resemble those produced by a magnetic stimulator was designed and built. This paper presents general guidelines that cover hardware aspects and components required for designing and fabricating such a device.
