Individuals with ankle dorsiflexion restriction may present altered movement patterns and cause a series of dysfunction. Therefore, the aim of this research was to clearly determine the effects of peak ankle dorsiflexion angle on lower extremity biomechanics and pelvic motion during walking and jogging.<\/jats:p><\/jats:sec><jats:sec><jats:title>Method<\/jats:title><jats:p>This study involved 51 subjects tested for both walking and jogging. The motion capture system and force measuring platforms were used to synchronously collect kinematics and kinetics parameters during these activities. Based on the peak ankle dorsiflexion angle during walking, the 51 subjects were divided into a restricted group (RADF group, angle &amp;lt;10\u00b0) and an ankle dorsiflexion-unrestricted group (un-RADF group, angle &amp;gt;10\u00b0). Independent-Sample <jats:italic>T<\/jats:italic>-tests were performed to compare the pelvic and lower limb biomechanics parameters between the groups during walking and jogging test on this cross-sectional study.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The parameters that were significantly smaller in the RADF group than in the un-RADF group at the moment of peak ankle dorsiflexion in the walking test were: ankle plantar flexion moment (<jats:italic>p<\/jats:italic> &amp;lt;\u20090.05), hip extension angle (<jats:italic>p<\/jats:italic> &amp;lt;\u20090.05), internal ground reaction force (<jats:italic>p<\/jats:italic> &amp;lt;\u20090.05), anterior ground reaction force (<jats:italic>p<\/jats:italic> &amp;lt;\u20090.01), pelvic ipsilateral tilt angle (<jats:italic>p<\/jats:italic> &amp;lt;\u20090.05). In contrast, the external knee rotation angle was significantly greater in the RADF group than in the un-RADF group (<jats:italic>p<\/jats:italic> &amp;lt;\u20090.05). The parameters that were significantly smaller in the RADF group than in the un-RADF group at the moment of peak ankle dorsiflexion in the jogging test were: peak ankle dorsiflexion angle (<jats:italic>p<\/jats:italic> &amp;lt;\u20090.01); the anterior ground reaction force (<jats:italic>p<\/jats:italic> &amp;lt;\u20090.01), the angle of pelvic ipsilateral rotation (<jats:italic>p<\/jats:italic> &amp;lt;\u20090.05).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>This study shows that individuals with limited ankle dorsiflexion experience varying degrees of altered kinematics and dynamics in the pelvis, hip, knee, and foot during walking and jogging. Limited ankle dorsiflexion alters the movement pattern of the lower extremity during walking and jogging, diminishing the body\u2019s ability to propel forward, which may lead to higher injury risks.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fneur.2023.1269061","type":"journal-article","created":{"date-parts":[[2024,2,1]],"date-time":"2024-02-01T12:14:31Z","timestamp":1706789671000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":33,"title":["Effects of peak ankle dorsiflexion angle on lower extremity biomechanics and pelvic motion during walking and jogging"],"prefix":"10.3389","volume":"14","author":[{"given":"Yi","family":"Rao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nan","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianyu","family":"Gao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Si","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haitao","family":"Shi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yiqun","family":"Lu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuang","family":"Ren","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongshi","family":"Huang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2024,2,1]]},"reference":[{"key":"ref1","volume-title":"Kinesiology of the musculoskeletal system: foundations for rehabilitation 2nd edition, chapter 14: ankle and foot","author":"Neumann","year":"2013"},{"key":"ref2","doi-asserted-by":"publisher","first-page":"73","DOI":"10.1016\/s0966-6362(02)00196-0","article-title":"High- and low-ankle flexibility and motor task performance","volume":"18","author":"Moseley","year":"2003","journal-title":"Gait Posture"},{"key":"ref3","doi-asserted-by":"publisher","first-page":"955","DOI":"10.1093\/ptj\/67.6.955","article-title":"Evaluation of functional ankle dorsiflexion using subtalar neutral position.
