Influence of reference electrode position on the compound muscle action potential.
CONCLUSION: A proximal E2 position records a lower volume conducted signal and yields a CMAP that is more representative of the muscle over which the E1 (active) electrode is placed.
SIGNIFICANCE: The proposed 'Proximal E2' montage may be better suited to assess pathology.
