However, previously used tasks have been controlled, and it is unclear whether clinical measurements of the ankle DF-ROM, are associated with landing positions during sport-specific task. This study sought to determine the relationship between ankle DF-ROM and landing positions.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>Thirty male soccer players participated in this study. The ankle DF-ROM was measured by the weight bearing lunge test in degrees using a cell phone app (TiltMeter). Landing patterns were assessed during a soccer-specific task using landing error scoring system items using Kinovea software. Simple correlations were used to evaluate the relationships between ankle DF-ROM and landing error scores.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>Significant correlations were found between ankle DF-ROM and landing errors (<jats:italic>r<\/jats:italic> = -0.450, P = 0.006). A decreased ankle DF-ROM was associated with greater landing errors in a soccer specific situation.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusion<\/jats:title>\n<jats:p>These results suggest that ankle DF-ROM may serve a useful clinical measure for identifying poor landing posture in the real-world environment. Therefore, assessment of ankle DF-ROM could be included in the screening process, which could help identify the cause of the faulty motion.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0283150","type":"journal-article","created":{"date-parts":[[2023,3,16]],"date-time":"2023-03-16T17:40:40Z","timestamp":1678988440000},"page":"e0283150","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":17,"title":["Ankle dorsiflexion range of motion and landing postures during a soccer-specific task"],"prefix":"10.1371","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7899-5528","authenticated-orcid":true,"given":"Hadi","family":"Akbari","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2981-2470","authenticated-orcid":true,"given":"Yohei","family":"Shimokochi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0278-6890","authenticated-orcid":true,"given":"Bahram","family":"Sheikhi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2023,3,16]]},"reference":[{"issue":"8","key":"pone.0283150.ref001","doi-asserted-by":"crossref","first-page":"473","DOI":"10.1136\/bjsm.2004.015511","article-title":"Soccer injury in the lower extremities","volume":"39","author":"P Wong","year":"2005","journal-title":"Br J Sports Med"},{"issue":"1","key":"pone.0283150.ref002","doi-asserted-by":"crossref","first-page":"16","DOI":"10.1007\/s00167-013-2739-x","article-title":"Prevention of non-contact anterior cruciate ligament injuries in sports.
