However, appropriate approaches to the underwear design are still being explored. In order to establish an appropriate first-order design strategy for supportive underwear, clarifying the relationship between the pressure from the underwear and the amount of elevation of the bladder neck is necessary. We constructed a finite element model of the pelvis based on magnetic resonance images of a subject in an upright position, experimentally explored Young\u2019s modulus of the soft tissue and analyzed the amount of elevation of the bladder neck when changing the combination of applied pressures from the underwear. The position of the bladder neck relatively elevated when the pressure in the region from the abdomen to the pubis decreased and when the pressure in the region from the perineum to the coccyx increased, suggesting an appropriate design for the supportive underwear.<\/jats:p>","DOI":"10.1177\/09544119211047058","type":"journal-article","created":{"date-parts":[[2021,9,21]],"date-time":"2021-09-21T11:17:25Z","timestamp":1632223045000},"page":"269-278","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":3,"title":["Development of primary design guidelines for supportive underwear to elevate the bladder neck in women based on finite element analysis of the pelvis"],"prefix":"10.1177","volume":"236","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7083-8659","authenticated-orcid":false,"given":"Daisuke","family":"Tawara","sequence":"first","affiliation":[{"name":"Department of Mechanical Engineering and Robotics, Ryukoku University, Otsu, Shiga, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohiro","family":"Nishiki","sequence":"additional","affiliation":[{"name":"Medical Equipment Division, Engineering Department, Shiga Equipment Factory, TAKARA BELMONT Corp., Konan, Shiga, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanae","family":"Ninomiya","sequence":"additional","affiliation":[{"name":"Faculty of Nursing, Osaka Medical and Pharmaceutical University, Takatsuki, Osaka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hisayo","family":"Okayama","sequence":"additional","affiliation":[{"name":"Faculty of Medicine, University of Tsukuba, Tsukuba, Ibaraki, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiyoko","family":"Naito","sequence":"additional","affiliation":[{"name":"Faculty of Education Welfare, Biwako-Gakuin University, Higashi-Omi, Shiga, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shigehiro","family":"Morikawa","sequence":"additional","affiliation":[{"name":"Molecular Neuroscience Research Center, Shiga University of Medical Science, Otsu, Shiga, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2021,9,21]]},"reference":[{"key":"bibr1-09544119211047058","doi-asserted-by":"publisher","DOI":"10.2217\/WHE.13.17"},{"key":"bibr2-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1111\/j.1464-410X.2009.08427.x"},{"key":"bibr3-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2006.09.019"},{"key":"bibr4-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1016\/j.urology.2006.03.035"},{"key":"bibr5-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2014.12.012"},{"key":"bibr6-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-015-2626-8"},{"key":"bibr7-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1111\/luts.12185"},{"key":"bibr8-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1016\/j.maturitas.2010.11.006"},{"key":"bibr9-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1016\/j.eururo.2009.04.006"},{"key":"bibr10-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1007\/s00192-007-0452-3"},{"key":"bibr11-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1111\/j.1442-2042.2008.02117.x"},{"key":"bibr12-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1590\/S1516-31802007000500003"},{"key":"bibr13-09544119211047058","doi-asserted-by":"publisher","DOI":"10.1111\/luts.12023"},{"key":"bibr14-09544119211047058","unstructured":"B\u00f8 K, Berghmans B, M\u00f8rkved S, et al.
