Participants completed three trials of both planned and unplanned single\u2010leg landing onto an inverted force platform while reactive joint kinematic data were collected from initial\u2010contact to 200\u2009ms after initial\u2010contact. Two\u2010way repeated measures ANOVAs were used to examine the differences between condition (planned\u2010, unplanned\u2010conditions) and group (CAI, coper, control).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>There were significant group by condition interactions for total ankle displacement in the frontal plane (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.01) and maximum ankle inversion velocity (<jats:italic>p<\/jats:italic>\u00a0=\u00a00.01).

Current data suggest that altered reactive joint kinematics under the unanticipated condition in CAI patients may contribute to the condition of CAI after ankle sprains. Clinicians should focus on rehabilitation programs to recover and\/or develop feedback control for CAI patients during functional movements under unanticipated condition to prevent further injuries.<\/jats:p><\/jats:sec>","DOI":"10.1111\/sms.14342","type":"journal-article","created":{"date-parts":[[2023,2,25]],"date-time":"2023-02-25T07:44:35Z","timestamp":1677311075000},"page":"1116-1124","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Effects of anticipation on joint kinematics during inversion perturbation in individuals with chronic ankle instability"],"prefix":"10.1111","volume":"33","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2037-7668","authenticated-orcid":false,"given":"Seunguk","family":"Han","sequence":"first","affiliation":[{"name":"Department of Exercise Sciences Brigham Young University  Provo Utah USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4007-9898","authenticated-orcid":false,"given":"Hyunwook","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Exercise Sciences Brigham Young University  Provo Utah USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jon Tyson","family":"Hopkins","sequence":"additional","affiliation":[{"name":"Department of Exercise Sciences Brigham Young University  Provo Utah USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,3,5]]},"reference":[{"issue":"4","key":"e_1_2_9_2_1","first-page":"364","article-title":"Functional anatomy, pathomechanics, and pathophysiology of lateral ankle instability","volume":"37","author":"Hertel J","year":"2002","journal-title":"J Athl Train"},{"key":"e_1_2_9_3_1","doi-asserted-by":"publisher","DOI":"10.4085\/1062-6050-447-17"},{"key":"e_1_2_9_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40279-013-0111-4"},{"key":"e_1_2_9_5_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40279-013-0102-5"},{"key":"e_1_2_9_6_1","doi-asserted-by":"publisher","DOI":"10.1097\/00005768-199905000-00013"},{"key":"e_1_2_9_7_1","doi-asserted-by":"publisher","DOI":"10.1123\/jsr.2018-0061"},{"key":"e_1_2_9_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jelekin.2017.11.009"},{"key":"e_1_2_9_9_1","doi-asserted-by":"publisher","DOI":"10.4085\/1062-6050-43.2.179"},{"issue":"2","key":"e_1_2_9_10_1","first-page":"154","article-title":"Development and reliability of the ankle instability instrument","volume":"41","author":"Docherty CL","year":"2006","journal-title":"J Athl Train"},{"key":"e_1_2_9_11_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2013-093175"},{"key":"e_1_2_9_12_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.humov.2019.01.013"},{"key":"e_1_2_9_13_1","doi-asserted-by":"publisher","DOI":"10.1177\/1071100715576517"},{"key":"e_1_2_9_14_1","doi-asserted-by":"publisher","DOI":"10.1249\/MSS.0000000000001255"},{"key":"e_1_2_9_15_1","doi-asserted-by":"publisher","DOI":"10.1109\/TBME.1979.326551"},{"key":"e_1_2_9_16_1","doi-asserted-by":"publisher","DOI":"10.4085\/1062-6050-49.3.28"},{"key":"e_1_2_9_17_1","doi-asserted-by":"publisher","DOI":"10.1123\/mcj.7.3.264"},{"key":"e_1_2_9_18_1","doi-asserted-by":"publisher","DOI":"10.1097\/00003086-200408000-00027"},{"issue":"2","key":"e_1_2_9_19_1","first-page":"121","article-title":"Reactive muscle firing of anterior cruciate ligament\u2010injured females during functional activities","volume":"34","author":"Swanik CB","year":"1999","journal-title":"J Athl Train"},{"key":"e_1_2_9_20_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546508328102"},{"key":"e_1_2_9_21_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546511422323"},{"key":"e_1_2_9_22_1","doi-asserted-by":"publisher","DOI":"10.1080\/02640414.2013.868917"},{"key":"e_1_2_9_23_1","doi-asserted-by":"publisher","DOI":"10.1249\/MSS.0000000000002282"},{"key":"e_1_2_9_24_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.gaitpost.2021.09.182"}],"container-title":["Scandinavian Journal of Medicine &amp;
