What is Nerve conduction?

Nerve conduction is a technique that analyzes the electrical functions of nerves and muscles. Let us remember that the nerves send electrical impulses so that the muscles move in certain ways, and when these signals are received, it is possible to measure their transmission and response speed and efficiency.

It detects nerve and muscle abnormalities that are usually manifested through the following symptoms:

  • Tiredness and lack of strength in the muscles. 
  • Numbness or tingling in the limbs and face. 
  • Muscle contraction and cramps.
  • Muscle immobility. 

In a nerve conduction test, electrodes will be placed on the affected muscles and they will send electrical signals as a stimulus to the nerve so that it sends impulses to the muscle; by measuring its response time, it will be possible to determine the conductive speed.

This technique has no risk for the patient and the only discomfort is a mild tingling in the area where the electrodes are when receiving electrical stimulation.

Among the most frequent conditions that can be diagnosed with nerve conduction, are:

  • Amyotrophic lateral sclerosis.
  • Guillain Barre syndrome.
  • Myasthenia and dystrophia. 
  • Carpal tunnel syndrome. 
  • Herniated discs. 

At the Neurophysiology Clinic we are prepared to offer you the most advanced neurophysiological tests to diagnose the various pathologies that affect your nervous system, which represent a quantitative, reproducible, and generally non-invasive measure that enriches the neurological examination, providing an interaction platform and support in the diagnosis and treatment of neurologically affected patients.

The tests we perform include all the tools of a comprehensive neurophysiology service:

  • Electroencephalogram.
  • Electromyography.
  • Evoked potentials.
  • Outpatient polysomnography.
  • Hospital polysomnography.
  • Transcranial doppler.
  • Neuro-otology tests.
  • Otoacoustic emissions.
  • Intraoperative monitoring.
  • Magnetic stimulation.
