Electromyography (EMG) is a technique for evaluating and recording the electrical activity produced by skeletal muscles. EMG is performed using an instrument called an electromyograph to produce a record called an electromyogram.
EMG, Inc. is the current legal name of an American company based in Santa Rosa, California that manufactures guitar pickups and EQ accessories. Among guitar and bass accessories, the company sells active humbucker pickups, such as the EMG 81 , [1] the EMG 85 , the EMG 60 , and the EMG 89 .
Electromyography (EMG) has been proposed by multiple researchers as an alternative measurement technique to quantify spasticity. The use of EMG offers a quantitative value of severity as opposed to relying on subjective scoring protocols.
An electromyogram (EMG) is an electrical recording of the activity of a muscle or muscle group. An EMG study can be combined with a nerve conduction study to diagnose neuromuscular diseases such as peripheral neuropathy and amyotrophic lateral sclerosis .
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 surgery.
Nerve conduction studies are used mainly for evaluation of paresthesias ( numbness, tingling, burning) and/or weakness of the arms and legs. The type of study required is dependent in part by the symptoms presented. A physical exam and thorough history also help to direct the investigation.
The most widely used methods of recording spontaneous electrical activity are various forms of electrodiagnostic testing (electrography) such as electrocardiography (ECG), electroencephalography (EEG), and electromyography (EMG).
The H-reflex test is performed using an electric stimulator, which gives usually a square-wave current of short duration and small amplitude (higher stimulations might involve alpha fibers, causing an F-wave, compromising the results), and an EMG set, to record the muscle response.
In neuroscience, nerve conduction velocity ( CV) is the speed at which an electrochemical impulse propagates down a neural pathway. Conduction velocities are affected by a wide array of factors, which include age, sex, and various medical conditions.
Facial electromyography (fEMG) refers to an electromyography (EMG) technique that measures muscle activity by detecting and amplifying the tiny electrical impulses that are generated by muscle fibers when they contract.
