Abstract:
An apparatus for measuring sensory and motor nerve conduction with automatic setting of stimulus intensity, comprising:(a) a stimulator capable of producing a stimulus and for applying said stimulus to a nerve;(b) a detector capable of detecting at least two sequential evoked signals from said nerve or from a muscle innervated by said nerve in response to said stimulus; and(c) a controller for automatically determining an operable stimulus intensity at which to measure nerve conduction in response to said stimulus and said evoked signal and for directing said stimulator to stimulate said nerve at said operable stimulus intensity, said controller comprising a comparator for comparing said at least two sequential evoked signals until one evoked signal is greater than a predetermined faction of an immediately succeeding evoked signal,whereby nerve conduction is then measured using said operable stimulus intensity.
