However, postural stability and the underpinning joint action remain unclear. This study aimed to identify differences in postural response to a mediolateral moving platform during single\u2010leg stance between individuals with CAI and healthy controls (HC). Twenty\u2010three CAI and 23 HC participants performed balance tasks during 1\u2010s mediolateral perturbation. Ground reaction force and kinematic data were recorded, and margin of stability (MoS), and joint torques in the frontal plane were calculated for their first successful trial. The CAI group showed increased MoS during sudden changes in platform movement direction (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.045) and the phase after platform stop (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009=\u20090.033) compared to the HC, suggesting a less effective postural response to external perturbations. These findings suggest a less stable postural strategy in people with CAI during single\u2010leg stance with perturbation. The weaker relationship between MoS and hip\u2010 and trunk\u2010 torque in the CAI than HC group in response to the perturbation provided evidence for reduced effectiveness of joint actions in postural control. Sudden base of support changes, such as accelerations and decelerations, are shown to be effective in identifying postural impairments in CAI. Further research is needed to determine whether these impairments can be improved through practice.\n                  <\/jats:p>","DOI":"10.1111\/sms.70345","type":"journal-article","created":{"date-parts":[[2026,7,10]],"date-time":"2026-07-10T12:07:51Z","timestamp":1783685271000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Reduced Effective Postural Responses to External Perturbations in Chronic Ankle Instability"],"prefix":"10.1111","volume":"36","author":[{"given":"Xiaohan","family":"Xu","sequence":"first","affiliation":[{"name":"Public Health and Sports Sciences Department University of Exeter  Exeter UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joanna","family":"Bowtell","sequence":"additional","affiliation":[{"name":"Public Health and Sports Sciences Department University of Exeter  Exeter UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William R.","family":"Young","sequence":"additional","affiliation":[{"name":"Public Health and Sports Sciences Department University of Exeter  Exeter UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel T.
