The NM-01/CPT is an electrodiagnostic device designed for automated neuroselective sensory nerve conduction threshold assessment, specifically targeting the painless current perception threshold (CPT). Through microprocessor-controlled, neuro-selective electrical stimuli, the system swiftly and painlessly quantifies the conduction threshold and functional integrity of large and small myelinated, as well as small unmyelinated sensory nerve fibers individually, on any skin surface of the body.
