Nerve conduction studies are beneficial to diagnose certain diseases of the nerves of the body. The test is not invasive, but can be painful due to the electrical shocks administered during the test. The shocks are associated with a low amount of electric current, so they pose minimal risk to the patients.
Several types of channels capable of producing the positive feedback necessary to generate an action potential do exist. Voltage-gated sodium channels are responsible for the fast action potentials involved in nerve conduction. Slower action potentials in muscle cells and some types of neurons are generated by voltage-gated calcium channels.
Electromyoneurography (EMNG) is the combined use of electromyography and electroneurography [1] This technique allows for the measurement of a peripheral nerve's conduction velocity upon stimulation (electroneurography) alongside electrical recording of muscular activity (electromyography). Their combined use proves to be clinically relevant by ...
Over time, newer techniques, such as somatosensory evoked potentials, single fiber electromyography, autonomic testing, and neuromuscular ultrasound have evolved as useful complementary techniques to nerve conduction studies and elecytromyography, which remain the core of electrodiagnostic medicine.

Saltatory conduction. In neuroscience, nerve conduction velocity (CV) is the speed at which an electrochemical impulse propagates down a neural pathway.Conduction velocities are affected by a wide array of factors, which include age, sex, and various medical conditions.
President-elect Donald Trump, after rejecting House Speaker Mike Johnson's plan to avoid a government shutdown, worked the phones on Thursday, showing wavering confidence in Johnson and claiming ...
Nerve injury classification assists in prognosis and determination of treatment strategy for nerve injuries. Classification was described by Seddon in 1943 and by Sunderland in 1951. [ 1 ] In the lowest degree of nerve injury the nerve remains intact, but signaling ability is damaged, termed neurapraxia .
