How long does it take to perform the sNCT/CPT procedure?
The average time needed to perform a three-frequency test at single site test is approximately 10 minutes. Keep in mind, however, that each test is equivalent performing three different neurodiagnostic procedures, since the Neurometer® CPT procedure independently evaluates all three major subpopulations of sensory nerve fibers comprising more than 90% of the typical sensory nerve. All other neurodiagnostic procedures measure only a single subpopulation of fibers – typically the large myelinated fibers which only make up around 10% of a sensory nerve. A typical evaluation may involve testing 2 to 6 sites (1 to 3 sites bilaterally) making the total time for a test approximately 20 to 60 minutes. The Neurometer® CPT/C, NervScan NS3000 and NervScan 2000 also feature a Ranged CPT (RPCT) mode that can perform three independent neuroselective tests on a nerve in about three minutes.
