  Surface Electromyography (SEMG)
Surface electromyography (SEMG) is a non-invasive procedure involving the detection, recording and interpretation of the electric activity of groups of muscles at rest and during activity.
Needle electromyography is an invasive procedure that records the electrical activity of individual muscles and is considered a more reliable technology.
Surface electromyography is occasionally used as an aid to diagnose neuromuscular disorders, determine the need for surgery in individuals with low back pain, and assist in evaluating the prognosis of disorders involving muscle lesions.

 Myosymmetries Calgary - Surface Electromyography (sEMG)
Surface electromyography (sEMG) is a recent development emerging from the field of biofeedback.
This became known as surface electromyography in order to distinguish it from needle electromyography as practiced in neurology.
It was discovered that the electrical activity of a muscle and that of a single motor unit could be increased or decreased upon command through conscious mental control.

 About Electromyography (EMG)
Electromyography is a test for certain problems of nerves and muscles.
This test is most often used for people who might have carpal tunnel syndrome, where it is still the most reliable test.

Single-fiber electromyography (SFEMG) is a selective EMG recording technique that allows identification of action potentials (APs) from individual muscle fibers.
The stimulating electrode is inserted into the muscle near an intramuscular nerve fiber, and the recording electrode is inserted distally near muscle fibers innervated by this nerve.
Recording position of the single-fiber electromyography electrode during jitter analysis with voluntary muscle activation.

 Dubious Use of Surface Electromyography (SEMG)
Samuel Homola, D.C. In surface electromyography (SEMG), the electrical activity of individual muscles or muscle groups is detected, amplified, and analyzed by a computer [A, B].
However, chiropractors who market a commonly used SEMG device claim that it provides an objective measurement of overall spinal health by detecting electrical activity in the muscles along the spine (paraspinal electromyography), enabling them to screen patients initially and to follow the progress of their treatment [1].
Furthermore, the use of advanced technology of any type would be considered clinically unnecessary if the ultimate potential benefit of using the advanced technology would have no significant effect on the overall outcome for the patient when compared to the outcome obtained without utilization of the advanced technology [7].

Electromyography (EMG) and nerve conduction studies (NCS) are special tests used to detect neuromuscular disorders.
An EMG measures the electrical activity of muscles, and NCS measure the speed and intensity of electrical signals that travel through nerves and the time it takes muscles to respond to these signals.

 Electromyography (EMG) and Nerve Conduction Velocity (NCV) - My Child Has - Children's Hospital Boston
An EMG is actually a two-part test consisting of nerve conduction studies (NCS) and electromyography (EMG).
Initially the electromyographer performs the nerve conduction studies by stimulating the various nerves along their course.
Subsequently, in the electromyography part, the physician inserts tiny electrodes into the muscles.

 MDA / Quest Vol 7 No 5 /Simply Stated . . .
Sometimes, a doctor can infer this functional defect - and the disease associated with it - by giving a physical exam, doing a blood test or looking at the anatomy of nerves and muscles.
But other times, the doctor may have to directly evaluate the functions of nerves and muscles and the connections between them by using two complementary techniques - nerve conduction velocity testing (NCVs) and electromyography (EMGs).
Both NCV and EMG rely on the fact that the activity of nerves and muscles produces electrical signals called action potentials.
