How long does it take to perform the sNCT/CPT procedure?


The average time needed to perform a fully automated CPT evaluation (p<0.004) at any single site test site is approximately 8-10 minutes. The ranged R-CPT measure is a faster faster measure, requiring approximately 2-3 minutes per site (p<0.05). The R-CPT measure is site specific. Presently, normative values exist to permit R-CPT measures to be obtained from 34 different body sites. Each frequency dependent measure obtained provides a unique neurodiagnostic profile from each of the three major sub-populations of sensory nerve fibers comprising the typical sensory nerve. All other electrodiagnostic procedures measure only a single subpopulation of fibers - usually the large myelinated fibers which comprise approximately10% 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. Other measures that may be obtained such as Pain Tolerance Threshold (PTT) or allodynia evaluation typically require less than two minutes. top of page Previous page Home
