What are electromyography (EMG) and nerve conduction studies(NCV)?

Electromyography (EMG) and nerve conduction studies are tests that measure the electrical activity of muscles and nerves. Nerves send out electrical signals to make your muscles react in certain ways. As your muscles react, they give off these signals, which can then be measured

EMG tests and nerve conduction studies can both help find out if you have a disorder of your muscles, nerves, or both. These tests can be done separately, but they are usually done at the same time

  • An EMG test looks at the electrical signals your muscles make when they are at rest and when they are being used.
  • A nerve conduction study measures how fast and how well the body’s electrical signals travel down your nerves.

What is Autonomic (ANS) testing?

Autonomic testing helps find out if your autonomic nervous system (ANS) is working as well as it should. Your ANS controls body functions that happen automatically (without you thinking about them). These include breathing, heartbeat, body temperature, and digestion. If there are problems with the function of the ANS, it’s known as autonomic neuropathy. The most common causes of autonomic neuropathy include diabetes, autoimmune diseases, some types of medicines, and certain infections, such as HIV/AIDS.

  • Autonomic testing can show which part of the ANS is affected and how seriously it’s affected. This can help your provider develop the most effective treatment strategy.

What is a QEEG?

Quantitative Electroencephalography (qEEG) is a procedure that processes the recorded EEG activity from a multi-electrode recording using a computer.

This multi-channel EEG data is processed with various algorithms, The digital data is statistically analyzed, sometimes comparing values with “normative” database reference values.

The processed EEG is commonly converted into color maps of brain functioning called “Brain maps”. The EEG and the derived qEEG information can be interpreted and used by experts as a clinical tool to evaluate brain function, and to track the changes in brain function due to various interventions such as neurofeedback or medication
