Area of Science:

  • Neuroscience
  • Clinical Electrophysiology

Background:

  • The sural nerve is crucial for sensory feedback from the lower leg.
  • Understanding its electrophysiological properties is vital for diagnosing neuropathies.

Purpose of the Study:

  • To establish normative data for sural nerve sensory action potential (SAP) parameters.
  • To investigate the influence of age, gender, and recording distance on SAP amplitude and conduction velocity.

Main Methods:

  • Orthodromic near-nerve technique used to record SAP in 273 healthy subjects (5-90 years).
  • SAP recorded at multiple sites from the foot to the S-1 root.
  • Analysis of amplitude and conduction velocity variations.

Main Results:

  • Sural nerve SAP amplitude was 32% higher in females than males at midcalf, likely due to volume conduction.
  • SAP amplitude decreased exponentially with age and with increasing conduction distance (power relationship, exponent 1.4-1.7).
  • Conduction velocity was slightly slower in distal nerve segments.

Conclusions:

  • Age and conduction distance significantly impact sural nerve SAP amplitude.
  • Gender differences in amplitude exist, potentially related to body composition and volume conduction.
  • These findings provide essential normative data for clinical neurophysiological assessments of the sural nerve.
