Evaluation of female pelvic floor muscles using surface electromyography: literature review

Abstract

Surface electromyography has clinical and research importance for the physiotherapist. Although capturing electrical activity promoted by recruitment of motor units, there is a good correlation between the number of activated units and muscle strength. This is one of the methods of higher specificity in pelvic floor evaluation, although the lack of consensus regarding its application. The aim of this literature review was to cluster information regarding to the use of surface electromyography in the evaluation of pelvic floor. Papers were searched in Medline, Pubmed Lilacs, SciELO and Cochrane Library. Were selected papers which methods used surface electromyography to evaluate the pelvic floor. Although its methodology still lacks standardization, is an instrument that should be considered in scientific research in our country because it seems to have good reproducibility and reliability. Women with pelvic floor disorders have changes in the activation time of the pelvic floor muscles (PFM) and abdominal muscles. With respect to pregnancy and postpartum, there is a lack of evidence on possible changes in electrical activation of PFM in these periods.
