Electromyography (EMG)/Nerve Conduction Velocity/Evoked Potential

Dr. Semente offers state of the art diagnostics including electromyography (EMG), nerve conduction velocity, and evoked potential to improve your treatment. Contact us here to make an appointment with our chiropractor in Suffolk County for diagnostic services in conjunction with chiropractic care.

Electromyography (EMG)

EMG involves using a needle (called an electrode) to collect information about the electrical activity in your muscles. This type of test is done to help diagnose conditions such as nerve root injuries, nerve compression, and specific conditions such as amyotrophic lateral sclerosis (ALS). The needle that is inserted into the muscle measures the electrical activity of the muscle to test the health of the nerve pathways.

  1. How long does it take?

The test can take anywhere from thirty to sixty minutes in total.

Nerve Conduction Velocity

A nerve conduction velocity test (NCV), also known as a nerve conduction study (NCS) is done to measure the speed of the electrical impulse as it travels through a nerve. The test involves the attachment of electrode patches to the skin to stimulate the nerve. The speed of the impulse is measured as it travels from one electrode to the other. The results can indicate a nerve injury.

    1. What does NCV test for?


NCV can indicate the presence of any of the following conditions:

    • Carpal tunnel syndrome
    • Herniated disc
    • Sciatic nerve issues
    • Guillain-Barr√© syndrome


    1. How long does it take?


This test can take anywhere from fifteen minutes to one hour.

Evoked Potential

Evoked potential tests are used to examine the electrical activity in the brain when certain stimuli are presented to the patient. For example, certain stimuli may be presented in the form of sight, sound or sensation to show how the signals are traveling along the nerves. There are three different tests that can be conducted to test the auditory nerves (BAEP), optic nerve (VEP), and sensory nerves (SEP).

    1. What does it test for?


  • Evoked potential tests test for disorders such as multiple sclerosis and optic nerve dysfunction.
  • This type of test may not explicitly show what condition a patient is suffering from, but it helps to assess the function of specific nerves.


  • How long does it take?



      • Evoked potential testing takes about two hours if all three tests are being done.
