Ankle-foot orthoses are often prescribed to improve gait mechanics in individuals with lower extremity injuries; however, their design may compromise how the foot rolls over the ground.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Objectives:<\/jats:title>\n            <jats:p>The aim of this study was to investigate the effects of the sagittal plane ankle-foot orthosis alignment on roll-over shape and center of pressure velocity in individuals with lower limb reconstructions.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Study design:<\/jats:title>\n            <jats:p>Randomized cross-over study with a control group comparison.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Methods:<\/jats:title>\n            <jats:p>In total, 12 individuals with lower limb reconstruction who used a custom carbon ankle-foot orthosis and 12 uninjured controls underwent gait analysis. Ankle-foot orthosis users were tested in their clinically-provided ankle-foot orthosis alignment, with an alignment that was 3\u00b0 more plantarflexed, and with an alignment that was 3\u00b0 more dorsiflexed. Components of roll-over shape and center of pressure velocity were calculated from heel strike on the ankle-foot orthosis limb to contralateral heel strike.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results:<\/jats:title>\n            <jats:p>Roll-over shape radius was not affected by 3\u00b0 changes to alignment and was not significantly different from controls. Aligning the ankle-foot orthosis in more dorsiflexion than clinically provided resulted in a smaller peak center of pressure velocity that occurred later in stance.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusion:<\/jats:title>\n            <jats:p>Individuals using custom carbon ankle-foot orthoses can accommodate 3\u00b0 alterations in the dorsiflexion or plantarflexion alignment.<\/jats:p>\n          <\/jats:sec>","DOI":"10.1177\/0309364620971407","type":"journal-article","created":{"date-parts":[[2020,11,21]],"date-time":"2020-11-21T05:24:28Z","timestamp":1605936268000},"page":"147-152","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":10,"title":["The effect of custom carbon ankle-foot orthosis alignment on roll-over shape and center of pressure velocity"],"prefix":"10.1097","volume":"45","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5321-0333","authenticated-orcid":false,"given":"Elizabeth","family":"Russell Esposito","sequence":"first","affiliation":[{"name":"DoD-VA Extremity Trauma and Amputation Center of Excellence, San Antonio, TX, USA"},{"name":"Center for Limb Loss and Mobility, VA Puget Sound, Seattle, WA, USA"},{"name":"Center for the Intrepid, Brooke Army Medical Center, San Antonio, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8331-2485","authenticated-orcid":false,"given":"Mitchell D","family":"Ruble","sequence":"additional","affiliation":[{"name":"Center for the Intrepid, Brooke Army Medical Center, San Antonio, TX, USA"},{"name":"Henry M.
