===Nerve conduction velocity===

[[Nerve conduction velocity]] is an important aspect of nerve conduction studies. It is the speed at which an [[electrochemical]] [[impulse (psychology)|impulse]] propagates down a neural pathway. Conduction velocities are affected by a wide array of factors, including age, sex, and various medical conditions. Studies allow for better diagnoses of various neuropathies, especially demyelinating conditions as these conditions result in reduced or non-existent conduction velocities. To perform nerve conduction velocity, surface electrodes are placed onto the skin over nerves at various locations. Each patch sends electrical impulses which stimulate the nerve. Resulting electrical activity of nerve is recorded by the other electrodes. The distance between electrodes and the time it takes for electrical impulses to travel between electrodes are used to determine the velocity of the nerve signals.<ref name="Garg2012">{{cite journal|last=Garg|first=Ruchika|year=2012|title=Footdrop in the Farmers in Punjab: A Retrospective Electrodiagnostic Study|journal=Journal of Clinical and Diagnostic Research|volume=6|issue=10|pages=1653–1657|issn=2249-782X|doi=10.7860/JCDR/2012/4829.2648|pmid=23373021|pmc=3552197}}</ref>
