NASCIMENTO, Gerlane Karla Bezerra Oliveira et al. Surface electromyography of the masseter muscle during chewing: a systematic review. Rev. CEFAC [online]. 2012, vol.14, n.4, pp.725-731.  Epub 29-Maio-2012. ISSN 1982-0216.

The chewing, a complex action controlled by the central nervous system, is one of the most important functions of the Stomatognathic System. During this action, the electrical activity of the masticatory muscles may be quantified using a surface electromyography. In order to systematically review the literature, on the methods and foods used in EMGS masseter muscle during mastication, we carried out a search in the databases SciELO, Brazil, Lilacs and Medline / Pubmed, from September to October 2009. We included population-based studies and excluded review studies without clear methodological definition and studies with children, adolescents and elderly. About 657 articles were found at the intersection of the following descriptors and their corresponding in English: chewing and masseter and electromyography, which 12 of them selected. It was found that the methods involved in the execution of surface electromyography of the masseter muscle during mastication, vary according to each author, and there is no standard for a specific food in order to perform the examination.
