Common sites for IM injections include the following: 1. The ventrogluteal muscle is the preferred site for adults and children over the age of 1 year because there are no large nerves or vessels, it is a large muscle, it is sealed by bone and contains less fat (Berman et al., 2008). 2.
electromyogram (EMG). Recording of electrical activity of a muscle associated with contraction and relaxation. This is obtained by placing a microelectrode within a muscle.The recording process is called electro-myography. diagnostic test that records the electrical activity of muscles. In the test, small electrodes are placed on or in the skin; the patterns of electrical activity are projected on a screen or over a loudspeaker. This procedure is used to test for muscle disorders, including muscular dystrophy. Mentioned in: Myopathies.
The detection, amplification, and recording of changes in skin voltage produced by underlying skeletal muscle contraction is called electromyography, and the recording thus obtained is called an electromyogram (EMG). Power is defined as the amount of work done per unit of time.echanical work, in the physical sense, refers to the application of a force that results in the movement of an object. Skeletal muscle performs mechanical work when the muscle contracts and an object is moved, as in lifting a weight.
