Neurometer^® CPT electrodiagnostic devices perform sensory nerve conduction threshold (sNCT) evaluations by determining current perception threshold (CPT) levels. The Neurometer® CPT/C device utilizes three unique neuro-selective electrical stimuli to perform extremely sensitive quantitative assessments of all major subpopulations of sensory nerve fibers at any cutaneous site. The non-invasive, painless stimulus makes the Current Perception Threshold (CPT) examination an ideal replacement for procedures hampered by low patient compliance. The extreme sensitivity of the CPT evaluation enables quantification of the hyperesthesia that precedes progressive nerve impairment, as well as hypoesthetic conditions.

        Modes of operation include single and double blind, manual and automated CPT determinations, with customizable application-specific modes available. The Ranged CPT (RCPT) mode allows fast and accurate evaluations in only minutes per site subject. An animal testing (ART) mode provides an atraumatic neuroselective current threshold procedure ideally suited for laboratory investigations. The nociceptive (NCPT) and pain perception threshold (PTT) mode provides a reproducible, non-invasive and atraumatic method for obtaining pain thresholds in small and large fibers (if present).

        Neuval(TM) DBII CPT Database and Analysis Software, included with each device, performs a multi-dimensional analysis of CPT measures comparing them to established healthy measures and a narrative laboratory report is generated. Hundreds of peer reviewed publications and presentations have established the reliability of the CPT examination which is eligible for third party reimbursement.

        The CPT/C is portable, rechargeable-battery powered, and features a Remote Switch Box for direct patient control and a printer for accurate documentation of exams. The Neurometer® CPT/C stimulus is self calibrating, and its patented circuitry maintains the constant current output regardless of normal variations in skin thickness, impedance and temperature. Built-in Compliance Guard(TM) software monitors the consistency of patient response - further assuring high reproducibility. The Neurometer® CPT/C examination is perfect for large scale screening as well as detailed mapping out of nerve impairment - providing significant benefits for you and your patient.
