Frequently Asked Questions

What Do Electroneurodiagnostic Technologists Do?

Electroneurodiagnostic (END) technologists prepare patients for procedures, obtain medical histories, record electrical potentials, calculate results, maintain equipment, and may work with specific treatments. They develop a good rapport with patients and comfort them during the recording procedure, which can last from 20 minutes (for a single nerve conduction study) to 8 hours (for an overnight sleep study). END technologists understand neurophysiology and recognize the normal and abnormal electrical activity. They act as eyes and ears for specially trained doctors who later review and interpret the data. Considerable individual initiative, reasoning skill, and sound judgment are all expected of the Electroneurodiagnostic professional.

What types of Procedures do END Technologists Perform?

The following are the most common Electroneurodiagnostic procedures:
Electroencephalography (EEG) is the spontaneous electrical activity of the brain. EEGs assist in the diagnosis of various brain disorders, it helps to evaluate the effects of head trauma or the consequences of severe infectious disease, and assists in determining the level of consciousness or stages of sleep. EEG information can help determine that the brain receives oxygen during various surgeries. The electroencephalogram (EEG) is the most known electroneurodiagnostic test.


Evoked Potential (EP) is a recording of electrical activity from the brain, brain stem, and peripheral nerves elicited by a specific stimulus to the visual, auditory or somatosensory pathways. The stimulus produces a characteristic wave pattern. Evoked Potentials may be monitored during surgery while the patient is unconscious, thus help prevent damage to the nervous system. Evoked Potentials can also be used to help with the diagnosis of neurological diseases.

Polysomnography (PSG) is a special Electroneurodiagnostic procedure that uses various physiologic monitors to monitor a person’s sleep pattern, breathing, heart activity, and limb movements. It helps to evaluate sleep and various sleep disorders, most commonly sleep apnea. It also helps to assess the effectiveness of the treatment of these disorders.

Nerve conduction studies (NCS) is a test, which can identify nerve damage. The test measures how fast an electrical impulse moves through the peripheral nerves in the Updated 04/2019 by JJ 9 extremities. Technologists stimulate the nerve with an electrical current and then record how long it takes the nerve impulse to reach the muscle.

Intraoperative Monitoring (IOM) is the use of various electroneurodiagnostic tests described above to monitor the functional integrity of different neural structures (brain, brain stem, spinal cord, peripheral nerves) during surgery. The types of surgeries include a wide range including orthopedic, neurosurgery, or vascular.

Long Term Monitoring (LTM) is a specific kind of monitoring utilizing EEG over long periods of time. This type of prolonged EEG recording is used primarily for Epilepsy monitoring but is also widely used in the intensive care units, the operating room, or in the emergency department.

What is the Career Outlook for END Technologists?

Employment opportunities are abundant. Particularly strong growth areas are Electroencephalography, Long Term Monitoring, and Intraoperative Monitoring due to the growing recognition of the value of these tests, and subsequent expansion of these departments. There is a continuous need for well-educated Electroneurodiagnostic Technologists. The demand grows as new labs open and existing labs expand.


How Much Do They Earn?

Salaries depend on education, experience, level of responsibility, and area of the country. Salaries range from $37,000 for new graduates of END programs to over $73,000 per year for lab managers or independent contractors. As of June 2018, the median salary for all END technologists across the country is $52,272 according to Salary.com. (www.salary.com) Technologists who hold professional credentials, college degrees, and who owned their own business commanded the highest salaries.


What Basic Qualifications Do Electroneurodiagnostic Students Need?

Students must have actively inquiring minds, above average intelligence, and a willingness to engage in life-long learning. Students must also have tact, patience, and compassion. Manual dexterity and a capacity to deal with visual, electrical, and computer concepts are important. They must be interested in biology, human anatomy, mathematics and grammar
