These alterations negatively affect functional mobility and movement efficiency. Although gait retraining is commonly recommended in rehabilitation, objective evidence on its short-term biomechanical effects remains limited. This study aimed to evaluate the immediate impact of a single-session standardized movement training intervention on gait biomechanics in children with JIA. Methods: Seventeen children with JIA underwent pre\u2013post gait assessments using the Xsens MVN Awinda wearable motion capture system. The intervention focused on step symmetry, stride length, heel\u2013toe progression, and upright trunk posture, delivered by an experienced physiotherapist following a standardized protocol. Scalar kinematic outcomes were analyzed using paired statistical tests, and time-normalized kinematic waveforms were compared with healthy reference data from 25 age-matched participants derived from the COMPWALK-ACL dataset. Results: Significant improvements were observed in multiple gait parameters following the intervention. Trunk lateral lean decreased significantly (p = 0.0002; d = \u22121.35), indicating enhanced postural stability. Significant changes were also found in ankle dorsiflexion\u2013plantarflexion (p = 0.0081; d = 0.83) and knee flexion\u2013extension (p = 0.0252; d = 0.68). Waveform analyses showed increased similarity to healthy patterns, particularly in trunk and knee kinematics. Spatiotemporal parameters reflected a slower, more controlled gait pattern, with increased stride time and stance duration. Conclusions: A single session of standardized movement training can produce immediate improvements in gait biomechanics in children with JIA, especially in trunk control and lower-limb kinematics. Wearable motion analysis provides a sensitive tool for detecting these short-term adaptations and supports the inclusion of structured movement training in pediatric JIA rehabilitation.<\/jats:p>","DOI":"10.3390\/jcm15103650","type":"journal-article","created":{"date-parts":[[2026,5,11]],"date-time":"2026-05-11T17:17:42Z","timestamp":1778519862000},"page":"3650","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Short-Term Effects of Targeted Movement Training on Gait Kinematics in Children with Juvenile Idiopathic Arthritis: A Motion Analysis Study"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1553-3304","authenticated-orcid":false,"given":"Sibel","family":"\u00d6zbal","sequence":"first","affiliation":[{"name":"Department of Biomedical Engineering, Graduate School of Natural and Applied Sciences, Acibadem Mehmet Ali Aydinlar University, Istanbul 34752, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Asya","family":"Albayrak","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy and Rehabilitation, Faculty of Health Sciences, Istanbul Kent University, Istanbul 34406, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0764-205X","authenticated-orcid":false,"given":"Asena","family":"Yekdaneh","sequence":"additional","affiliation":[{"name":"Program of Physiotherapy, Vocational School of Health Services, Fenerbah\u00e7e University, Istanbul 34758, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0003-7438-8829","authenticated-orcid":false,"given":"\u0130rem","family":"D\u00f6nmez","sequence":"additional","affiliation":[{"name":"Physiotherapy and Rehabilitation Master of Science Program, Institute of Graduate Studies, Istanbul University-Cerrahpasa, Istanbul 34320, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3594-7387","authenticated-orcid":false,"given":"Nuray","family":"Aktay Ayaz","sequence":"additional","affiliation":[{"name":"Division of Pediatric Rheumatology, Department of Pediatrics, Istanbul Faculty of Medicine, Istanbul University, Istanbul 34093, T\u00fcrkiye"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0830-6595","authenticated-orcid":false,"given":"Nilay","family":"Arman","sequence":"additional","affiliation":[{"name":"Department of Physiotherapy and Rehabilitation, Faculty of Health Sciences, Istanbul University-Cerrahpasa, Istanbul 34320, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hande","family":"Argunsah","sequence":"additional","affiliation":[{"name":"Department of Biomedical Engineering, Graduate School of Natural and Applied Sciences, Acibadem Mehmet Ali Aydinlar University, Istanbul 34752, Turkey"},{"name":"Department of Biomedical Engineering, Faculty of Engineering and Natural Sciences, Acibadem Mehmet Ali Aydinlar University, Istanbul 34752, Turkey"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,5,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Leblebici, G., K\u0131sa, E.P., Tarakc\u0131, E., and Kasap\u00e7opur, \u00d6.
