主权项 1. A method for performing neurophysiologic assessments, comprising: determining a threshold current level on a first channel of a neuromonitoring device, said first channel associated with a first myotome, wherein determining the threshold current level on the first channel includes: delivering stimulation signals within tissue, and monitoring neuromuscular responses on said first channel to determine when said stimulation signals evoke a significant neuromuscular response, wherein said stimulation signals are delivered as a sequence of pulses and wherein the current level of each pulse is adjusted from an immediately preceding pulse until the current level required to evoke a significant neuromuscular response is determined; and omitting one or more pulses from the sequence of pulses when the neuromuscular response to the omitted pulse is predictable based upon data obtained while determining the threshold current level of the first channel.
