Although toes play an important role in stabilizing standing posture and walking, many aspects of the effects of FT on the body remain unclear. To our knowledge, there have been no reports about the relationship between FT and postural stability, especially in children. This study aimed to clarify the prevalence of FT and its relationship with static postural stability in children. Of the 400 children aged 8 years who participated in our cohort study, 396, who were examined for static postural stability, were included in this study. Postural stability and FT were assessed using a foot pressure plate. The sway path length of the center of pressure and the area of the ellipse defined as the size of the area marked by the center of pressure, were measured as an evaluation of static postural stability. We calculated the \u201cfloating toe score (FT score: small FT score indicates insufficient ground contact of the toes)\u201d using the image of the plantar footprint obtained at the postural stability measurement. The rate of FT was elevated at more than 90%, and the FT score in the eyes-closed condition was significantly higher than that in the eyes-open condition in both sexes. The FT score significantly correlated with the center of pressure path and area. Our results suggest that ground contact of the toes is not directly related to static postural stability in children, but it may function to stabilize the body when the condition becomes unstable, such as when the eyes are closed.<\/jats:p>","DOI":"10.1371\/journal.pone.0246010","type":"journal-article","created":{"date-parts":[[2021,3,24]],"date-time":"2021-03-24T13:44:01Z","timestamp":1616593441000},"page":"e0246010","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":15,"title":["Prevalence of floating toe and its relationship with static postural stability in children: The Yamanashi adjunct study of the Japan Environment and Children\u2019s Study (JECS-Y)"],"prefix":"10.1371","volume":"16","author":[{"given":"Taro","family":"Fujimaki","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6311-7909","authenticated-orcid":true,"given":"Masanori","family":"Wako","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kensuke","family":"Koyama","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Naoto","family":"Furuya","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ryoji","family":"Shinohara","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanae","family":"Otawa","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Kobayashi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sayaka","family":"Horiuchi","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Megumi","family":"Kushima","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zentaro","family":"Yamagata","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5630-9600","authenticated-orcid":true,"given":"Hirotaka","family":"Haro","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"on behalf of The Yamanashi adjunct study of the Japan Environment and Children\u2019s Study Group","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"340","published-online":{"date-parts":[[2021,3,24]]},"reference":[{"key":"pone.0246010.ref001","doi-asserted-by":"crossref","first-page":"459","DOI":"10.1136\/pgmj.8.86.459","article-title":"Use and abuse of toes","volume":"8","author":"C Lambrinudi","year":"1932","journal-title":"Postgrad Med J"},{"key":"pone.0246010.ref002","doi-asserted-by":"crossref","first-page":"549","DOI":"10.1002\/jor.20661","article-title":"The role of the great toe in balance performance","volume":"27","author":"SW Chou","year":"2009","journal-title":"J Orthop Res"},{"key":"pone.0246010.ref003","doi-asserted-by":"crossref","first-page":"245","DOI":"10.1302\/0301-620X.72B2.2312564","article-title":"The importance of the toes in walking","volume":"72","author":"J Hughes","year":"1990","journal-title":"J Bone Joint Surg"},{"key":"pone.0246010.ref004","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1589\/jpts.23.33","article-title":"Occurrence of floating toe from the viewpoint of the structure of foot arch","volume":"23","author":"K Fukuyama","year":"2011","journal-title":"J Phys Ther Sci"},{"key":"pone.0246010.ref005","doi-asserted-by":"crossref","first-page":"3159","DOI":"10.1589\/jpts.27.3159","article-title":"Incidence of floating toe and its association with the physique and foot morphology of Japanese children","volume":"27","author":"T Araki","year":"2015","journal-title":"J Phy Ther Sci"},{"key":"pone.0246010.ref006","doi-asserted-by":"crossref","first-page":"1507","DOI":"10.1302\/0301-620X.87B11.16590","article-title":"The Weil osteotomy.
