Written recording of the contraction of muscles as a result of receiving electrical stimulation.
a test to evaluate nerve and muscle function.
A recording of electrical activity from the muscular system; in sleep recording, synonymous with resting muscle activity or potential. The chin/cheek EMG, along with EEG and EOG, is one of the three basic variables used to score sleep stages and waking. Sleep recording in humans utilizes surface electrodes to measure activity from the submental or masseter muscles. These reflect maximally the changes in resting muscle activity. The chin/cheek EMG is tonically inhibited during REM sleep.
This is a mechanism used to measure muscle activity. It is usually attached to a subject's chin in sleep and dream experiments.
A measurement of muscle tension. The data is collected through sensors.
(EMG) • A graphic recording of electrical potentials from muscle.
A recording of the electrical activity of nerve and muscle cells, measured with an extremely sensitive galvanometer. The electromyogram is used to help detect and diagnose a variety of disorders of peripheral nerves and muscles.
A test done to evaluate muscle function

Test used to record electrical activity of muscles.
a graphical record of electric currents associated with muscle contractions
an examination performed by inserting very fine needle electrodes into selected muscles and recording and interpreting the electrical patterns that they produce at rest and during muscular contraction
a procedure in which small electrodes are placed into a muscle
a test that measures the electrical activity in your nerves and muscles
electro-my'oh-gram; EMG A graphic representation of the somatic electric currents associated with muscular actions. Electrodes are usually placed on the chin or jaw and the tibialis anterior muscle. The chin or jaw EMG helps identify muscle activity associated with tongue movement opening the upper airway. The tibialis EMG identifies leg movement associated with myoclonus, periodic leg movement (PLMs) and restless leg syndrome (RLS). Term: Definition: Description
also called an EMG; the measurement and recording of muscle activity, particularly under the chin, along the jaw, and on the legs.
a measurement of the electrical activity associated with muscle movements.
a graphic record of the contraction of a muscle electrically stimulated
Referred to as a nerve conduction study, used to identify nerve damage.
measures muscles tension.
A test that records the responses of muscles to electrical stimulation.
Test to determine nerve function.
A test used to detect abnormal muscle electrical activity that can occur in many diseases and conditions, most often performed when patients have unexplained muscle weakness. This test involves using electrodes to send electric signals through nerves.
An electromyogram (EMG) is an instrument that records electrical currents generated in an active muscle.
plot of the electrical activity produced by muscular contraction, recorded by a fine needle inserted in the muscle. It is used to determine the origin of muscular problems muscles or nerves.
An electrical test of muscle contraction.
A recording of electrical activity from the muscular system/muscle activity; Used to assist in the scoring of sleep stages such as REM; Also used to measure muscle activity to help diagnose PLMS
A record of activity in muscles, used in diagnosing muscle and nerve disorders.
a test that measures the electrical activity of a muscle or a group of muscles. An EMG can detect abnormal electrical muscle activity due to diseases and neuromuscular conditions.
A recording of the electrical activity of the muscles. The absence of very low level of EMG activity indicates the presence of REM sleep. Very high levels can help identify periods of wakefulness. Non-invasive EMG is recorded in both diagnostic and CPAP titration sleep studies.
