Background: Dorsal sural sensory nerve action potential (SNAP) could help diagnose early or subclinical peripheral neuropathy.
Objectives: To establish reference data for dorsal sural SNAP amplitude, latency, and velocity in healthy participants.
Materials And Methods: A prospective study was conducted in 45 nerves from healthy participants between 18 and 90 years and stratified into three age groups (a = 18-40 years, b = 41-60 years, and c>60 years).
