On the standardized left and right footprints of 46 healthy adults (23 women and 23 men; 19\u201326 years old), the outline of each foot excluding the toes was identified and its shape was quantified independently from size by the elliptic Fourier analysis. The symmetry in shape was quantified on an intra\u2010subject basis by calculating a morphologic distance D between the mathematical reconstructions of the left and right footprints of each subject, Symmetry in size was assessed by the right\u2010to\u2010left area ratio and found to be very good for all subjects; it ranged from 0.948 to 1.049. The subjects were also grouped by sex, and mean values were calculated, Within\u2010subject symmetry in the footprint shape appeared high, with morphologic distances ranging between 8.94 and 2.66 in men and between 7.15 and 3.09 in women, No consistent associations between footprint symmetry and age, body height and weight, or shoe size were found, On average, women had more symmetric size\u2010standardized footprints than did men (women: mean 4.57, SD 1.14; men: mean 5.46. SD 1.7; p 0.05), Mean size\u2010independent shapes of male and female left and right footprints were also calculated, Together with the analysis of individual asymmetry, they could be used for the quantitative diagnosis of borderline patients.<\/jats:p>","DOI":"10.1002\/jor.1100160619","type":"journal-article","created":{"date-parts":[[2005,2,24]],"date-time":"2005-02-24T06:20:24Z","timestamp":1109226024000},"page":"758-765","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":28,"title":["Foot asymmetry in healthy adults: Elliptic fourier analysis of standardized footprints"],"prefix":"10.1002","volume":"16","author":[{"given":"Chiarella","family":"Sforza","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni","family":"Michielon","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicola","family":"Fragnito","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Virgilio F.","family":"Ferrario","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2005,2,18]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.7547\/87507315-83-12-674"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/107110079601700306"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/0021-9290(93)90004-X"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1007\/BF02522509"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1834-7819.1991.tb00806.x"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/0003-9969(93)90027-J"},{"key":"e_1_2_1_8_2","first-page":"103","article-title":"A three\u2010dimensional evaluation of human facial asymmetry","volume":"186","author":"Ferrario VF","year":"1995","journal-title":"J Anat"},{"key":"e_1_2_1_9_2","doi-asserted-by":"crossref","first-page":"247","DOI":"10.1080\/08869634.1995.11678076","article-title":"New television technique for natural head and body posture analysis","volume":"13","author":"Ferrario VF","year":"1995","journal-title":"Cranio"},{"key":"e_1_2_1_10_2","first-page":"208","article-title":"Elliptic Fourier analysis of mandibular shape","volume":"16","author":"Ferrario VF","year":"1996","journal-title":"J Craniofac Genet Dev Biol"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3913(96)90176-6"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1097\/00004424-199601000-00001"},{"key":"e_1_2_1_13_2","first-page":"3","article-title":"Asymmetry in the human skeleton: a study on prehistoric Polynesians and Thais","volume":"33","author":"Huggare J","year":"1995","journal-title":"Eur J Morphol"},{"key":"e_1_2_1_14_2","first-page":"507","article-title":"The inheritance of vertebral shape in the mouse.
