Claim One:
1. A neuromonitoring system for performing multi-channel neurophysiologic assessments, comprising: a stimulator configured to deliver at least one electrical stimulation signal to a patient; at least one sensor coupled to a myotome, said sensor configured to detect a neuromuscular response evoked by said electrical stimulation signal; a control unit in communication with said stimulator and said at least one sensor, said control unit being configured to: (a) direct transmission of the electrical stimulation signals from said stimulator, (b) receive evoked neuromuscular response data from the sensor, (c) determine a threshold current level on a first channel of said neuromonitoring system, 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, (d) determine a threshold current level on a second channel of the neuromonitoring device, said second channel associated with a second myotome, wherein determining the threshold current level on the second channel includes: delivering stimulation signals within tissue and monitoring neuromuscular responses on said second 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 said 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; and (e) communicate the threshold current levels to a user.
