How is the sNCT/CPT procedure conducted?
The Neurometer® CPT sNCT electrodiagnostic examination employs a standardized, automated procedure to generate objective, quantitative measures of the conduction and functional integrity of sensory nerve fibers. The unit emits non-aversive transcutaneous electrical stimuli through a pair of gold plated electrodes to quantify neuroselective CPT values. The procedure includes testing the patient at one or more body sites with three different sinusoidal frequencies of electrical stimulus. Each frequency, 2000 Hz, 250 Hz, and 5 Hz, evokes a response from a different subpopulation of sensory nerve fibers, i.e. large myelinated, small myelinated and small unmyelinated fibers, respectively. Normative ranges of CPT values have been established and published for measures taken at multiple body sites and are used to analyze patient measures. Software included with each device can be used to analyze the data and print a report summarizing the results. The following is a brief description of the s
