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.
Electromyography (EMG) is an electrodiagnostic medicine 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.An electromyograph detects the electrical potential generated by muscle cells when these cells are electrically or neurologically activated.easured EMG potentials range between less than 50 Î¼V and up to 20 to 30 mV, depending on the muscle under observation. Typical repetition rate of muscle motor unit firing is about 7â20 Hz, depending on the size of the muscle (eye muscles versus seat (gluteal) muscles), previous axonal damage and other factors.
