A prolonged peroneus longus reaction time (PRT) is a hallmark neuromuscular deficit of CAI, but whether it forecasts the training response is unknown.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>We retrospectively analysed 183 adults with CAI who completed a supervised 12-week proprioceptive programme. Baseline PRT to sudden inversion was measured by surface electromyography. The primary outcome was the change in the Cumberland Ankle Instability Tool (CAIT); the Star Excursion Balance Test (SEBT) was secondary. Associations were tested with Pearson and partial correlation, analysis of covariance, multivariable linear regression and receiver-operating-characteristic analysis.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>CAIT improved from 18.4 to 22.2 points (mean change +3.8, p &lt; 0.001). Baseline PRT was inversely related to the CAIT gain (Pearson r = -0.51, 95% CI -0.61 to -0.39; partial r adjusted for baseline CAIT = -0.57). In the adjusted model PRT remained the strongest predictor (partially standardized \u03b2 = -2.09 CAIT points per SD, p &lt; 0.001). PRT discriminated non-responders with an area under the curve of 0.78 (95% CI 0.71-0.84).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>A shorter baseline peroneal reaction time was associated with a larger improvement after proprioceptive training. PRT is an inexpensive candidate marker that may help stratify CAI patients, although the retrospective single-centre design warrants prospective confirmation.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/10225536261480760","type":"journal-article","created":{"date-parts":[[2026,9,10]],"date-time":"2026-09-10T06:22:46Z","timestamp":1789021366000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Baseline peroneus longus reaction time predicts the response to proprioceptive training in chronic ankle instability: A single-centre retrospective cohort study"],"prefix":"10.1177","volume":"34","author":[{"given":"Fawu","family":"A","sequence":"first","affiliation":[{"name":"Beijing Jishuitan Hospital Guizhou Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0002-8277-938X","authenticated-orcid":false,"given":"Shengzhong","family":"Wu","sequence":"additional","affiliation":[{"name":"Beijing Jishuitan Hospital Guizhou Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jie","family":"Yang","sequence":"additional","affiliation":[{"name":"Beijing Jishuitan Hospital Guizhou Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kailiang","family":"Zhou","sequence":"additional","affiliation":[{"name":"Beijing Jishuitan Hospital Guizhou Hospital"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,9,9]]},"reference":[{"key":"e_1_3_6_2_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13047-021-00480-w"},{"key":"e_1_3_6_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jcot.2023.102328"},{"key":"e_1_3_6_4_2","doi-asserted-by":"publisher","DOI":"10.4085\/1062-6050-344-18"},{"key":"e_1_3_6_5_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-2007-1024683"},{"key":"e_1_3_6_6_2","doi-asserted-by":"publisher","DOI":"10.1111\/sms.14535"},{"key":"e_1_3_6_7_2","doi-asserted-by":"publisher","DOI":"10.3389\/fnhum.2024.1366443"},{"key":"e_1_3_6_8_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-025-00175-3"},{"key":"e_1_3_6_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/jfa2.70088"},{"key":"e_1_3_6_10_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13643-024-02455-x"},{"key":"e_1_3_6_11_2","doi-asserted-by":"publisher","DOI":"10.1186\/s12891-024-07800-8"},{"key":"e_1_3_6_12_2","doi-asserted-by":"publisher","DOI":"10.1186\/s13102-024-00845-1"},{"key":"e_1_3_6_13_2","doi-asserted-by":"publisher","DOI":"10.1371\/journal.pone.0311355"},{"key":"e_1_3_6_14_2","doi-asserted-by":"publisher","DOI":"10.7547\/23-008"},{"key":"e_1_3_6_15_2","doi-asserted-by":"publisher","DOI":"10.1038\/s41598-024-55555-y"},{"key":"e_1_3_6_16_2","doi-asserted-by":"publisher","DOI":"10.1177\/19417381231219198"},{"key":"e_1_3_6_17_2","doi-asserted-by":"publisher","DOI":"10.3390\/sports12100282"},{"key":"e_1_3_6_18_2","doi-asserted-by":"publisher","DOI":"10.1177\/10538127261419234"},{"key":"e_1_3_6_19_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsams.2018.11.001"},{"key":"e_1_3_6_20_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2006.05.022"},{"key":"e_1_3_6_21_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.apmr.2017.01.003"},{"key":"e_1_3_6_22_2","doi-asserted-by":"publisher","DOI":"10.1002\/jfa2.70115"}],"container-title":["Journal of Orthopaedic Surgery"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/10225536261480760","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/10225536261480760","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/10225536261480760","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,12]],"date-time":"2026-09-12T10:52:05Z","timestamp":1789210325000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/10225536261480760"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9]]},"references-count":21,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2026,9]]}},"alternative-id":["10.1177\/10225536261480760"],"URL":"https:\/\/doi.org\/10.1177\/10225536261480760","relation":{},"ISSN":["1022-5536","2309-4990"],"issn-type":[{"value":"1022-5536","type":"print"},{"value":"2309-4990","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,9]]},"article-number":"10225536261480760"}}
