What is the difference between testing sensory nerve conduction velocity using orthodromic conduction versus antidromic conduction?

Question

Quizplus · Accepted Answer

Orthodromic conduction examines sensory nerve conduction velocity in the physiological direction, from the distal to proximal end of the nerve, whereas antidromic conduction examines the opposite direction, from proximal to distal. This can affect the measured velocity due to differences in refractory periods and other factors. Additionally, orthodromic conduction is generally considered to be more reliable and accurate for clinical testing compared to antidromic conduction.
