The determination of the nerve conduction velocity (NLG) or also called electroneurography (ENG) is a procedure in which the electrical activities of nerves are measured. To do this, small electrodes are inserted on the skin over the nerve or directly on the nerve. The electrodes measure the electrical impulses emitted by the nerves when they are stimulated. 

Die ENG is commonly used to diagnose disorders of the nerves, such as neuropathies, nerve damage, and neuromuscular disorders.


It can also be used to monitor the effectiveness of treatments for such conditions. The procedure is usually safe and painless, but it can sometimes be uncomfortable if the electrical impulses are not tolerated.


The history of NLG began in the late 1800s with the work of Sir Charles Sherrington researching the basics of nerve physiology. 

In the 1930s, the German neurologist Ludo van Bogaert developed a method for measuring nerve conduction velocity, which he called "motor impedance measurement". In the 1950s, the first electrodes for measuring nerve conduction velocity were developed and further advances were made in the following years.

Since the 1970s, NLG technology has become an important tool for the diagnosis and monitoring of disorders of the peripheral nervous system, such as neuropathies, polyneuropathies, peripheral nerve lesions, and nerve compression syndromes such as carpal tunnel syndrome. It has also been used to monitor patients with spinal muscular atrophy and myasthenia gravis.

In the 1980s, computerized NLG systems were developed that allowed more precise and faster measurement of nerve conduction velocity. These advances have helped NLG technology become widespread in clinical practice and used to diagnose and monitor patients with peripheral nerve disease.

In summary, NLG technology has come a long way throughout history and is now an indispensable tool in the diagnosis and monitoring of diseases of the peripheral nervous system. The continuous advancement of the technology and its integration with other neurophysiological measurements offers great potential for exploring and improving the diagnosis and rehabilitation of neurological diseases.
