Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles. [ 1 ] [ 2 ] EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram .

Electromyography is the measurement and analysis of the electrical activity in skeletal muscles. This technique is useful for diagnosing the health of the muscle tissue and the nerves that control them. [8] EMG measures action potentials, called Motor Unit Action Potentials (MUAPs), created during muscle contraction.
This is a list of roots, suffixes, and prefixes used in medical terminology, their meanings, and their etymologies. Most of them are combining forms in Neo-Latin and hence international scientific vocabulary .
Intraoperative neurophysiological monitoring (IONM) or intraoperative neuromonitoring is the use of electrophysiological methods such as electroencephalography (EEG), electromyography (EMG), and evoked potentials to monitor the functional integrity of certain neural structures (e.g., nerves, spinal cord and parts of the brain) during
Electromyography (EMG) may show particular patterns in specific muscle diseases; for instance, McArdle's disease and phosphofructokinase deficiency show a phenomenon called cramp-like contracture. [18] There are genetic tests available for many of the hereditary muscle conditions that predispose to myoglobinuria and rhabdomyolysis. [12] [13]
Electromyoneurography (EMNG) is the combined use of electromyography and electroneurography [1] This technique allows for the measurement of a peripheral nerve's conduction velocity upon stimulation (electroneurography) alongside electrical recording of muscular activity (electromyography). Their combined use proves to be clinically relevant by ...
Surface EMG is more sensitive than needle electromyography and clinical observation in the detection of fasciculation in people with amyotrophic lateral sclerosis [2] (ALS). Deeper areas of contraction can be detected by electromyography (EMG) testing, though they can happen in any skeletal muscle in the body.
