WHAT DOES IT CONSIST OF?
Study that evaluates the electrical activity and conduction of nerve roots and peripheral nerves, is not an image study; it uses a gun that causes electric shocks and then a needle is used with which no electric touches are given, but if it gets into several muscles. It’s an annoying study but it’s tolerable, it doesn’t require sedation.

Dúchate o toma un baño poco antes del examen para eliminar los aceites de la piel.
-
No te apliques lociones ni cremas antes del examen.
Otras precauciones

-
Si tomas medicamentos anticoagulantes
-
Si tienes hemofilia, un trastorno de coagulación de la sangre que provoca sangrado prolongado
ELECTROMYOGRAPHY
WHAT DOES IT CONSIST OF?
Study that evaluates the electrical activity of the brain, (does not cause any pain) is performed by placing several electrodes in the head that are in turn connected to a computer, in it are recorded the changes that occur, the patient must be relaxed and may even sleep during the study
WHEN IS IT INDICATED?
It is advisable to perform in patients with symptoms of deterioration of the level of consciousness, loss of intellectual faculties (loss of memory, dementia) or episodes that lead to suspected seizures (epilepsy is a disease in which the brain abruptly discharges electrical impulses producing the attacks).
WHAT DO YOU DIAGNOSE?
It is able to determine changes in brain activity that may be helpful in diagnosing brain disorders, especially epilepsy or other seizure disorders. An EEG may also be helpful in diagnosing or treating the following disorders:
-
Brain tumor
-
Brain damage from head injuries
-
Brain dysfunctions that can have various causes (encephalopathy)
-
Inflammation of the brain (encephalitis)
-
stroke
-
Sleep disorders
¿Cuáles son las indicaciones?
-
Para una ejecución correcta de la prueba, es necesario que la cabeza esté limpia y libre de productos como gel o lacas. Se aplican sobre la cabeza del paciente electrodos de copa.
