The nerve conduction study is often combined with needle electromyography. The Department of Health and Human Services Inspector General recently identified the use of NCSs without a needle electromyography at the same time a sign of questionable billing. [9] The nerve conduction study consists of the following components:
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.

Whereas a clinical neurophysiologist is trained to perform all the following studies EEG, intraoperative monitoring, nerve conduction studies, EMG and evoked potentials, [3] and electrodiagnostic physician focuses mainly on nerve conduction studies, needle EMG, and evoked potentials. The American Board of Psychiatry and Neurology provides ...
Needle EMG may aid with the diagnosis of nerve compression or injury (such as carpal tunnel syndrome), nerve root injury (such as sciatica), and with other problems of the muscles or nerves. Less common medical conditions include amyotrophic lateral sclerosis , myasthenia gravis , and muscular dystrophy .
Collaborators do not perform or interpret needle electromyography (EMG) studies or interpret NCSs but are active in the field of neuromuscular medicine. AANEM research members are currently active in neuromuscular or electrodiagnostic research and are a PhD investigator, engineer, holder of a master's degree, or graduate student enrolled in a ...
A study conducted on patients with proximal radial nerve injuries used the procedure to indicate the degree of both pre- and postoperative nerve damage. [8] In this particular study, electromyoneurography was the preferred method of measuring recovery, chosen over magnetic resonance imaging ( MRI ) and computed tomography ( CT ) scans.
On nerve conduction studies, the pattern of diminished compound muscle action potential and normal sensory nerve action potential may be seen given that the lesion is proximal to the posterior root ganglion. Needle EMG is the more sensitive portion of the test, and may reveal active denervation in the distribution of the involved nerve root ...
The diagnosis may be supported by nerve conduction studies and medical imaging. [1] TOS is difficult to diagnose and there are many potential differential diagnoses as well as other diseases that are often co-occurrent with TOS. [5] Initial treatment for the neurogenic type is with exercises to strengthen the chest muscles and improve posture. [1]
