In terms of physiology this means that ortho- and antidromic waves can be generated from a localized excitation [79].
Recording the SNAP orthodromically refers to distal nerve stimulation and recording more proximally (the direction, in which physiological sensory conduction occurs) antidromic testing is the reverse (Figure 1).
Median sensory NCSs were performed using the antidromic technique; the recording electrode was placed over the palmar surface of the second digit and the nerve was stimulated from the wrist at 13 cm.
30] In an antidromic sensory conduction study performed in 59 patients with mild CTS demonstrated that recordings for digit I were the most sensitive measurements in the detection of decelerations in focal sensory nerve conduction velocities across wrists.
