A Review on Nerve Conduction Studies by Homa Mohseni Kouchesfahani SJPBS in Lupinepublishers
Electrophysiological measurements are indispensable tool for
investigating the functional integrity of peripheral nerves in
both clinical and laboratory environments. Nerve conduction study is a
property of both the axons and myelin sheath. The nerve
conduction velocity is highly dependent on rapid signal propagation
enabled by myelination. The compound motor action potential
(CMAP) which correlates with the number of functional axons is an
indicator for axonal damage when significantly reduced.
Because nerve conduction velocity (NCV) is sensitive to both myelin
sheath and axonal changes, it is an excellent measure of the
function of the peripheral nervous system. Nerve conduction studies may
be diagnostically helpful in patients suspected of having
almost any peripheral nervous system disorder including disorders of
nerve roots, peripheral nerves, muscle and neuromuscular
junction. Cranial nerves and spinal cord function may also be assessed.
Here, we mentioned the components and properties of nerve
conduction study.
