Electrophysiologic recordings demonstrated that activation of sensory nerve fibers, either by antidromic stimulation or capsaicin, depolarized these neurons. |
This reduction reflected the shunting and reduced amplitude of the antidromic action potential by the inhibition. |
Antidromic median sensory recording over digit 2 while stimulating the median nerve 13 cm proximal to the active electrode. |
However, a simultaneous comparison of both antidromic and orthodromic methods on the 4th digit has not been documented. |
