Shear wave elastography is an effective method for studying the condition of various musculoskeletal soft tissues. The primary aim of this study was the objective elastographic and electromyographic assessment of the pelvic floor during the rest and contraction of the pelvic floor muscles (PFM) in postmenopausal women. Methods. This was a prospective observational study that was carried out at the University Hospital in Wroclaw, Poland, between January 2017 and December 2019. Patients. The target group of the study included postmenopausal women with stress urinary incontinence. The primary outcomes were the features of the elastographic assessment of the pelvic floor during rest and contraction of the PFM obtained using shear wave elastography. Results. Based on the inclusion and exclusion criteria for the study, 14 patients took part in the measurements. There was a significant difference between the elastographic assessment of the pelvic floor during rest and contraction of the PFM at all locations in front of the urethra. No statistically significant correlation was found between the results of elastography and the bioelectrical activity of PFM. Conclusion. The elasticity of the periurethral structures is higher during active pelvic floor muscle contraction than at rest, it seems that shear wave elastography is an effective test that objectively assesses the strength of PFM contraction.<\/jats:p>","DOI":"10.3390\/diagnostics11112051","type":"journal-article","created":{"date-parts":[[2021,11,5]],"date-time":"2021-11-05T10:33:09Z","timestamp":1636108389000},"page":"2051","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["Assessment of the Elastographic and Electromyographic of Pelvic Floor Muscles in Postmenopausal Women with Stress Urinary Incontinence Symptoms"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5690-5226","authenticated-orcid":false,"given":"Kuba","family":"Ptaszkowski","sequence":"first","affiliation":[{"name":"Department of Clinical Biomechanics and Physiotherapy in Motor System Disorders, Wroclaw Medical University, Grunwaldzka 2, 50-355 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5933-3753","authenticated-orcid":false,"given":"Bartosz","family":"Ma\u0142kiewicz","sequence":"additional","affiliation":[{"name":"Department of Urology and Oncologic Urology, Wroclaw Medical University, Borowska 213, 50-556 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romuald","family":"Zdrojowy","sequence":"additional","affiliation":[{"name":"Department of Urology and Oncologic Urology, Wroclaw Medical University, Borowska 213, 50-556 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Malgorzata","family":"Paprocka-Borowicz","sequence":"additional","affiliation":[{"name":"Department of Clinical Biomechanics and Physiotherapy in Motor System Disorders, Wroclaw Medical University, Grunwaldzka 2, 50-355 Wroclaw, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lucyna","family":"Ptaszkowska","sequence":"additional","affiliation":[{"name":"Institute of Health Science, University of Opole, Katowicka 68, 45-060 Opole, Poland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,11,5]]},"reference":[{"key":"ref_1","first-page":"1140","article-title":"Symptoms at Postmenopause: Genetic and Psychosocial Factors","volume":"19","author":"Malacara","year":"2012","journal-title":"Menopause"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"160","DOI":"10.1016\/j.maturitas.2008.12.004","article-title":"Stress, Psychological Distress, Psychosocial Factors, Menopause Symptoms and Physical Health in Women","volume":"62","author":"Bauld","year":"2009","journal-title":"Maturitas"},{"key":"ref_3","doi-asserted-by":"crossref","first-page":"940","DOI":"10.1111\/j.1365-2702.2007.02112.x","article-title":"Menopausal Symptom Perception and Severity: Results from a Screening Questionnaire","volume":"17","author":"Berg","year":"2008","journal-title":"J.
