An understanding of the relationship between postural orientation and physical function may help guide decision making in rehabilitation. The aims were to evaluate (1) sex differences in visual assessment of Postural Orientation Errors (POEs) and (2) the association between POEs and objective and patient-reported physical function, in men and women with anterior cruciate ligament reconstruction (ACLR).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Twenty-four women and 29 men (mean 26.7 (SD 6.5) years) with ACLR were included. Six POEs (lower extremity and trunk) were scored from a video of five tasks with varying difficulty to compute POE scores (total and subscores). Objective physical function was evaluated with the single-leg hop for distance and side hop. Patient-reported physical function was evaluated using patient-reported outcome measures (PROMs).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Women had significantly more POEs than men (median difference 5.5\u201325, p\u22640.028). More POEs were associated with shorter hop distance and fewer side hops in women (r<jats:sub>s<\/jats:sub>= \u22120.425 to \u22120.518, p&lt;0.038), but not in men (r<jats:sub>s<\/jats:sub>&lt;0.301, p&gt;0.05). No associations were found between POE scores and PROMs, in either sex (r<jats:sub>s<\/jats:sub>&lt; \u20130.246, p&gt;0.05).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Women with ACLR seem to have more POEs compared with men, indicating worse postural orientation. More POEs were associated with worse hop performance, suggesting that POE scores may be used as criteria for rehabilitation progression. The lack of associations between POE scores and PROMs indicate that these measures complement each other.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/bmjsem-2021-001045","type":"journal-article","created":{"date-parts":[[2021,5,19]],"date-time":"2021-05-19T13:35:40Z","timestamp":1621431340000},"page":"e001045","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":6,"title":["Sex differences in postural orientation errors and association with objective and patient-reported function in patients with ACL injury: an exploratory cross-sectional study"],"prefix":"10.1136","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4072-6207","authenticated-orcid":false,"given":"Jenny","family":"Nae","sequence":"first","affiliation":[{"name":"Health Sciences, Lund University, Lund, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark W","family":"Creaby","sequence":"additional","affiliation":[{"name":"School of Exercise Science, Australian Catholic University, Brisbane, Queensland, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Cronstr\u00f6m","sequence":"additional","affiliation":[{"name":"Health Sciences, Lund University, Lund, Sweden"},{"name":"Department of Community Medicine and Rehabilitation, Ume\u00e5 Univerisity, Ume\u00e5, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8639-3006","authenticated-orcid":false,"given":"Eva","family":"Ageberg","sequence":"additional","affiliation":[{"name":"Health Sciences, Lund University, Lund, Sweden"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2021,5,19]]},"reference":[{"key":"2025083109485168000_7.2.e001045.1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2015-095898"},{"key":"2025083109485168000_7.2.e001045.2","doi-asserted-by":"crossref","first-page":"33","DOI":"10.1016\/j.berh.2019.01.018","article-title":"Evidence-based recommendations for the management of anterior cruciate ligament (ACL) rupture","volume":"33","author":"Filbay","year":"2019","journal-title":"Best Pract Res Clin Rheumatol"},{"key":"2025083109485168000_7.2.e001045.3","doi-asserted-by":"crossref","first-page":"ii7","DOI":"10.1093\/ageing\/afl077","article-title":"Postural orientation and equilibrium: what do we need to know about neural control of balance to prevent falls?","volume":"35 Suppl 2","author":"Horak","year":"2006","journal-title":"Age Ageing"},{"key":"2025083109485168000_7.2.e001045.4","doi-asserted-by":"crossref","first-page":"863","DOI":"10.2519\/jospt.2017.7270","article-title":"Measurement properties of a test battery to assess postural orientation during functional tasks in patients undergoing anterior cruciate ligament injury rehabilitation","volume":"47","author":"Nae","year":"2017","journal-title":"J Orthop Sports Phys Ther"},{"key":"2025083109485168000_7.2.e001045.5","doi-asserted-by":"crossref","first-page":"1542","DOI":"10.1093\/ptj\/pzaa092","article-title":"Extended version of a test battery for visual assessment of postural orientation errors: face validity, internal consistency, and reliability","volume":"100","author":"Nae","year":"2020","journal-title":"Phys Ther"},{"key":"2025083109485168000_7.2.e001045.6","doi-asserted-by":"publisher","DOI":"10.1177\/0363546510376053"},{"key":"2025083109485168000_7.2.e001045.7","doi-asserted-by":"publisher","DOI":"10.1177\/0363546504269591"},{"key":"2025083109485168000_7.2.e001045.8","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2016-096274"},{"key":"2025083109485168000_7.2.e001045.9","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2016.07.107"},{"key":"2025083109485168000_7.2.e001045.10","doi-asserted-by":"crossref","first-page":"8","DOI":"10.1016\/j.ptsp.2019.04.006","article-title":"Factors affecting knee abduction during weight-bearing activities in individuals with anterior cruciate ligament reconstruction","volume":"38","author":"Cronstr\u00f6m","year":"2019","journal-title":"Phys Ther Sport"},{"key":"2025083109485168000_7.2.e001045.11","doi-asserted-by":"crossref","DOI":"10.1186\/1471-2474-15-430","article-title":"Association between sensory function and medio-lateral knee position during functional tasks in patients with anterior cruciate ligament injury","volume":"15","author":"Cronstr\u00f6m","year":"2014","journal-title":"BMC Musculoskelet Disord"},{"key":"2025083109485168000_7.2.e001045.12","doi-asserted-by":"crossref","first-page":"917","DOI":"10.1007\/s40279-019-01093-x","article-title":"What is the evidence for and validity of Return-to-Sport testing after anterior cruciate ligament reconstruction surgery?
