What is electromyography (EMG)?

The electromyography or EMG is an electrodiagnostic test that is performed to test and assess the health of skeletal muscles and motor neurons — the nerve cells that control the muscles. The motor neurons send electrical signals through them that cause the muscles to...

What is an EEG system?

The electroencephalogram or EEG is a diagnostic test that is performed to detect irregularities and abnormalities in brain waves and to study cognitive processes. Electroencephalography is an electrophysiological process through which the electrical signals of the...

What is Intraoperative Neuromonitoring (IONM)?

Intraoperative neurophysiological monitoring or IONM is the technique of using electrophysiological methods suchlike electromyography (EMG), electroencephalography (EEG) and various evoked potentials to record and measure electrical potentials from the nervous system...
