Electrodiagnostic tests: Electromyography,
evoked potentials, and nerve conduction velocity testing,
that can be used to evaluate the health and function of nerves
or the muscles innervated by them.
Electromyography: Monitoring the electrical
function of muscles using needles placed into the muscle or
monitoring electrodes on the skin surface.
Electroneural interfaces: Advanced microchips
designed to have direct contact with nerves.
Eloquent: Complex neurological function.
Embolization: Passage of a solid material
through the blood stream that may result in blockage of some
Endplates: the portion of the cortical part
bone of the vertebral body that is immediately adjacent to
the intervertebral disc.
Endorphins: Natural morphine-like substances
within the bloodstream.
Endoscopes: Tubes used by surgeons to obtain
a view within the body without making a large incision, often
using fiber optics and video equipment.
Endotracheal tube: A tube placed in the throat
past the vocal cords used by an anesthesiologist to protect
and guarantee good ventilation and breathing during deep anesthesia.
Entubulation: A method of repairing nerves
involving the use of biosynthetic tube materials to connect
the nerves and promote nerve regrowth.
EOB: Explanation of benefits. A notice from
a insurance company explaining the payment or lack of payment
for a medical insurance claim.
Epidural: In the space just outside the dura.
Epidural abscess: An infection in the area
outside the dura membranes.
Epidural catheter: A catheter used to administer
pain medication in the area outside the dura.
Epidural injection: A generalized type of
treatment for spinal pain in which typically steroid medication
is spread over an area of dura.
Epidural stimulator: A type of electronic
device for applying a distracting stimulus to the low spinal
cord or nerves with involving the placement of an electrode
pad over the dura.
Epiduroscopy: The use of a video-based visualization
system to advance and move a catheter outside the dura and
inside the spinal canal,typically to lyse or breakup adhesions.
Ergonomics: The design of furniture, tools,
and equipment to minimize undesired physical stress on the
Esophagus: The tube carrying food from the
throat into the stomach.
Euphoria: A state of elation or excitement,
typically abnormal, associated with narcotic medication.
Evoked potentials: Electrical activity in
the brain or nerves caused by computer controlled equipment;
typically used to provide monitoring of the nervous system.
Exercise-based treatments: Nonsurgical treatment
for pain in involving bodily activity to produce relief of
Explanation of benefits: See EOB.
Extruded disc: A portion of the nucleus pulpous
passes entirely throught the annulus fibrosis and is free
within the spinal canal.
