The unique natural electrical properties of peripheral nerves can be evaluated in health and disease with externally applied stimuli and analysis of the consequent neurophysiologic responses. Nerve conduction study techniques permit stimulation and recording of electrical activity from individual peripheral nerves with sufficient accuracy, reproducibility, and standardization to determine normal values, characterize abnormal findings, and correlate neurophysiologic-pathologic features.
These clinical studies are used to:
●Diagnose focal and generalized disorders of peripheral nerves
●Classify peripheral nerve conduction abnormalities due to axonal degeneration, demyelination, and conduction block
●Prognosticate regarding clinical course and efficacy of treatment
