Electroneurodiagnostic (END) techs prep patients for numerous procedures,
record results, get medical histories and maintain complex equipment.
These technologists conduct many tests, including the electroencephalogram
(EEG), which is the most common; the evoked potential (EP); the polysomnogram
(PSG); the electronystagmogram (ENG); and nerve conduction studies (NCS).
Competent END technologists know the nervous system and know how to operate
sophisticated instruments. They're employed in hospitals, clinics, physicians'
offices, university medical centers and research centers.
This profession didn't exist a few decades ago, says Margaret Walcoff.
She is president of the American Society of Electroneurodiagnostic Technologists.
"It really is an outgrowth of EEG testing and the growth and expansion of
sleep testing and sleep labs from the late 1970s. A need started for testing
beyond the EEG so this career blossomed. This goes way beyond doing EEGs."
