For clinical use only. Values are cut-off limits from each cited source (for Ferrante EDX cases, includes the 5–9 years column where shown in the source table). Always consider clinical context, technique, and patient variables. This tool does not replace professional judgment.

Adult EMG reference values

Compare normative nerve conduction values (latency, amplitude, velocity) by author (Ferrante, Kimura, Preston, AANEM) and nerve.

This tool consolidates key adult nerve conduction normative values from widely used references in clinical electrodiagnostic practice.

Mark A. Ferrante (2019)

EMG Lesion Localization and Characterization: A Case Studies Approach. Demos Medical, 2019. Ferrante values here follow Table 9.1 of the EDX cases (Cleveland Clinic technique): includes the 5–9 years column and subsequent decade bands; distal latency and amplitude vary with age per the source.

Mayo Clinic

Mayo Clinic adult normative table for motor and sensory studies, including F-wave limits and cranial responses (facial and blink reflex), per the reference PDF used on this service.

Table data were extracted and consolidated from reference documents available to this service. Minor discrepancies between sources are expected and reflect methodological differences (distances, temperature, electrodes, populations). "-" means the author did not report that parameter.

Frequently asked questions

Which reference authors are included?

Ferrante, Kimura, Preston, AANEM and other classic normative sources, compared by nerve and parameter.

Can I use this table in academic work?

Yes, cite the canonical URL and access date. Confirm primary literature for formal publications.
