Previous research on the MLA includes measuring the calcaneal\u2013first metatarsal angle using a static sagittal plane radiograph, a dynamic height-to-length ratio using marker clusters with a multisegment foot model, and a contained angle using single point markers with a multisegment foot model. The objective of this study was to use biplane fluoroscopy to measure a contained MLA angle between foot types: pes planus (low arch), pes cavus (high arch), and normal arch. Fifteen participants completed the study, five from each foot type. Markerless fluoroscopic radiostereometric analysis (fRSA) was used with a three-dimensional model of the foot bones and manually matching those bones to a pair of two-dimensional radiographic images during midstance of gait. Statistically significant differences were found between barefoot arch angles of the normal and pes cavus foot types (p\u2009=\u20090.036), as well as between the pes cavus and pes planus foot types (p\u2009=\u20090.004). Dynamic walking also resulted in a statistically significant finding compared to the static standing trials (p\u2009=\u20090.014). These results support the classification of individuals following a physical assessment by a foot specialist for those with pes cavus and planus foot types. The differences between static and dynamic kinematic measurements were also supported using this novel method.<\/jats:p>","DOI":"10.1115\/1.4034463","type":"journal-article","created":{"date-parts":[[2016,8,22]],"date-time":"2016-08-22T16:44:02Z","timestamp":1471884242000},"update-policy":"https:\/\/doi.org\/10.1115\/crossmarkpolicy-asme","source":"Crossref","is-referenced-by-count":18,"title":["Medial\nLongitudinal Arch Angle Presents Significant Differences Between Foot Types: A Biplane Fluoroscopy\nStudy"],"prefix":"10.1115","volume":"138","author":[{"given":"Megan E.\nR.","family":"Balsdon","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristen\nM.","family":"Bushey","sequence":"first","affiliation":[{"name":"Wolf Orthopaedic Biomechanics Lab,Fowler Kennedy Sport Medicine Clinic,Western University,London, ON N6A 3K7, Canada;"},{"name":"Department of Mechanicaland Materials Engineering,Faculty of Engineering,Western University,London, ON N6A 5B9, Canadae-mail:\u2002kristen.bushey@gmail.com"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Colin\nE.","family":"Dombroski","sequence":"first","affiliation":[{"name":"SoleScience Inc.,Fowler Kennedy Sport Medicine Clinic,Western University,London, ON N6A 3K7, Canada;"},{"name":"Department of Physical Therapy,Faculty of Health Science,Western University,London, ON N6A 5B9, Canadae-mail:\u2002colin@solescience.ca"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Marie-Eve","family":"LeBel","sequence":"first","affiliation":[{"name":"Roth-McFarlane Hand and Upper Limb Centre,St. Joseph's Hospital,268 Grosvenor St.,London, ON N6A 4V2, Canadae-mail:\u2002mlebel4@uwo.ca"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas R.","family":"Jenkyn","sequence":"first","affiliation":[{"name":"Wolf Orthopaedic Biomechanics Lab,Fowler Kennedy Sport Medicine Clinic,Western University,London, ON N6A 3K7, Canada;"},{"name":"Department of Mechanicaland Materials Engineering,Faculty of Engineering,Western University,London, ON N6A 5B9, Canada;"},{"name":"School of Kinesiology,Faculty of Health Sciences,Western University,London, ON N6A 3K7, Canadae-mail:\u2002tjenkyn@uwo.ca"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"33","published-online":{"date-parts":[[2016,9,1]]},"reference":[{"issue":"3","key":"2020051311441016000_bib1","doi-asserted-by":"publisher","first-page":"452","DOI":"10.1016\/j.gaitpost.2012.09.008","article-title":"Foot Type Biomechanics Part 2: are Structure and Anthropometrics Related to Function?","volume":"37","year":"2013","journal-title":"Gait Posture"},{"issue":"5","key":"2020051311441016000_bib2","first-page":"688","article-title":"Pes Cavus and Pes Planus\u2014Analyses and Treatment","volume":"67","year":"1987","journal-title":"Phys.
