Electrodiagnostic testing is the umbrella term for studies that measure the electrical function of nerves and muscles. In practice it usually means nerve conduction studies with electromyography, though it also covers EEG and evoked potentials in the broader sense.

Electrodiagnostic medicine covers any study measuring electrical activity in the nervous system. In everyday use, when a clinician says electrodiagnostic testing they almost always mean nerve conduction studies combined with electromyography, assessing peripheral nerves and muscles. Used more broadly the field also includes electroencephalography, which records brain activity, and evoked potential studies, which measure conduction along specific sensory pathways. All of these are performed at both CNS offices.
This is the central point. Imaging shows anatomy; electrodiagnostic testing shows whether things are working. A nerve can look compressed on a scan with no functional consequence, and a nerve can be functionally damaged with entirely normal imaging. Nor can imaging grade how severe a nerve problem is or say how long it has been present, both of which electrodiagnostic testing can indicate. The two are complementary, and ordering one when the other is needed is a common source of wasted time.
This matters more than most people realise. The quality of an electrodiagnostic study depends heavily on who plans and performs it, because the protocol is adapted as findings emerge rather than fixed in advance. At CNS the neurologist who orders the study performs and interprets it, which is what allows it to be extended during the session. Both offices hold AANEM accreditation for their electrodiagnostic laboratories independently, and the practice was the first physician-owned outpatient EDX laboratory in Nevada to reach exemplary status.
Clinical Neurology Specialists has been physician-owned since 1998, when Leo Germin, M.D., FAANEM founded it. Five board-certified neurologists and four advanced practice providers see patients at the Las Vegas and Henderson offices, each with its own AANEM-accredited electrodiagnostic laboratory.
Clinical Neurology Specialists is an adult outpatient neurology practice for patients 18 and older. The practice performs no surgery and operates no imaging suite, infusion suite or interventional pain programme, and provides no emergency or inpatient care.
