“…Simulations indicated that a general decrease in EMG signal amplitude (whose magnitude depends on the thickness of the fluid layer) should be expected. However, these changes do not seem to be relevant for diagnostic purposes (Ekstedt & Stålberg 1973;Gootzen et al 1989;Brownell & Bromberg 2007). Needle size, type and insertion technique determine the pain or discomfort of the patient during the insertion (Strommen & Daube 2001).…”

Intramuscular electromyographic (EMG) signals are detected with needles or wires inserted into muscles. With respect to non-invasive techniques, intramuscular electromyography has high selectivity for individual motor unit action potentials and is thus used to measure motor unit activity. Decomposition of intramuscular signals into individual motor unit action potentials consists in detection and classification, usually followed by separation of superimposed action potentials. Although intramuscular EMG signal decomposition is the primary tool for physiological investigations of motor unit properties, it is rarely applied in clinical routine, because of the need for human interaction and the difficulty in interpreting the quantitative data provided by EMG signal decomposition to support clinical decisions. The current clinical use of intramuscular EMG signals relates to the diagnosis of myopathies, of diseases of the α-motor neuron and of the neuromuscular junction through the analysis of the interference signal or of the shape of some motor unit action potentials, usually without a full decomposition of the signal.

“…There is increased perception of pain when more than one muscle is sampled and in the upper extremities (including genioglossus in this study). Another consideration is the effect of using smaller pediatric concentric needles instead of standard concentric needles, which may lower motor unit action potential (MUAP) amplitude without a significant effect on MUAP duration . With these considerations, it is judicious to initially choose the most appropriate muscle to sample.…”

Utility and practice of electrodiagnostic testing in the pediatric population: An AANEM consensus statement

Nerve conduction studies and needle electromyography, collectively known as electrodiagnostic (EDX) studies, have been available for pediatric patients for decades, but the accessibility of this diagnostic modality and the approach to testing vary significantly depending on the physician and institution. The maturation of molecular diagnostic approaches and other diagnostic technologies such as neuromuscular ultrasound indicate that an analysis of current needs and practices for EDX studies in the pediatric population is warranted. The American Association of Neuromuscular & Electrodiagnostic Medicine convened a consensus panel to perform literature searches, share collective experiences, and develop a consensus statement. The panel found that electrodiagnostic studies continue to have high utility for the diagnosis of numerous childhood neuromuscular disorders, and that standardized approaches along with the use of high-quality reference values are important to maximize the diagnostic yield of these tests in infants, children, and adolescents.
