A Review on Nerve Conduction Studies
Journal Title: Scholarly Journal of Psychology and Behavioral Sciences - Year 2018, Vol 1, Issue 3
Abstract
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. Nerve conduction study is a simple and reliable test for evaluation of peripheral nerve function. The test is not invasive. In this technique nerve conduction in the largest and fastest myelinated fibers are recorded and it establishes the type and degree of abnormality. The site of lesion can be identified and localized[1]. This technique can be used for evaluation of conductive velocity in upper extremity, mostly the median and ulnar nerves and in the lower extremity including the peroneal, tibial, and sural nerves. NCS is a test commonly used to evaluate the function of the motor and sensory nerves of the human body. Nerve conduction studies are used mainly for evaluation of paresthesia (numbness, tingling, burning) and/or weakness of the arms and legs [1].
