What are NEUROMETER® CPT devices?
Neurometer® CPTs are electrodiagnostic devices which perform automated neuroselective sensory nerve conduction threshold (sNCT) evaluations by determining painless current perception threshold (CPT) levels. Using microprocessor controlled, neuroselective electrical stimuli, they quickly and painlessly quantify the conduction and functional integrity of the large and small myelinated and small unmyelinated sensory nerve fibers at any cutaneous site. CPT measures can detect and quantify early stage neuritis as well as peripheral sensory neuropathy. Neurometer® CPT devices generate three different constant alternating current sinusoid waveform stimuli at 2000 Hz, 250 Hz and 5 Hz. Stimulus output intensities range from 0.01 to 9.99 mAmperes (mA). The constant current output assures highly reproducible measures which are unaffected by variables such as skin thickness, temperature or edema. The device’s built in microprocessor is capable of performing both single-blind and fully automated do
