The orthodromic is the propagation of a nerve impulse in the same direction as a physiological conduction. The orthodromic nerve conduction studies are performed using a stimulus directed in the way the nerve normally depolarizes, for example, applying distal stimulation to the sensory fibers and recording responses more proximally. The stimulation can be applied at several sites such as the digit, palm, wrist or more proximally at the elbow and sensory nerve action potentials (SNAPs) can be recorded proximally on the palm, wrist, elbow or even at the axilla. The orthodromic studies were introduced since 1950s and mostly used until the first half of the 1970s but, in clinical practice, the sensory antidromic nerve conduction studies have been gradually the preferred methods because of higher SNAPs amplitude than orthodromic sensory nerve conduction studies.
