Neurometer® - Neurometer® CPT/C® electrodiagnostic devices provide painless, automated neuro-selective evaluations of both myelinated and unmyelinated fiber function. These assessments help map neuropathies, radiculopathies, and other sensory pathologies while detecting both painless and painful impairments, as well as subclinical nerve dysfunction. More than 30 years after leaving the laboratory for clinical applications ranging from Podiatry to Neurology and dozens of other specialties in-between, the Neurometer® evaluation continues to provide unique diagnostic measures of sensory nerve conduction thresholds (sNCT™s). The most widely used sNCT™ measure is Current Perception Threshold (CPT® ) which is the minimum amount of painless neuroselective electrical stimulus that consistently elicits a nerve response. The Neurometer generates a constant current stimulus by monitoring and compensating for tissue impedance variations. The stimulus evokes responses that quantify the functional integrity of each of the three major sub-populations of sensory nerve fibers. Specifically, A bata, A delta & C fiber groups are selectively stimulated by sinusoid waveform currents of 2000 Hz, 250 Hz and 5 Hz respectively. Using small surface electrodes, this test generates discrete double-blinded CPT measures (p<0.006) representing minimum detectable current intensities (+/- 20 uAmp.) for each fiber type.
