This study examined differences in average velocity, average step length, and single- and double-support percentages during gait under increasing task demands in individuals with a history of concussion. Sixty participants aged 18 to 35 years were recruited, including 32 individuals with a concussion within the past 3 to 18 months and 28 healthy controls. Gait data were collected using an instrumented pressure-sensitive walkway across four conditions: single-task and dual-task walking, with and without obstacles. Repeated-measures analyses of covariance were used to assess group and condition effects, with sex as a covariate, which showed a significant group-by-condition effect for step length, single-support percentage, and double-support percentage. These findings identify step length, single-support percentage, and double-support percentage as candidate sensor-derived gait biomarkers for detecting persistent post-concussion motor control alterations. The results directly support the use of pressure-based gait sensing to quantify deficits missed by conventional clinical measures; however, future work is needed to determine whether these features translate to wearable or real-world monitoring systems.<\/jats:p>","DOI":"10.3390\/s26144346","type":"journal-article","created":{"date-parts":[[2026,7,9]],"date-time":"2026-07-09T08:50:56Z","timestamp":1783587056000},"page":"4346","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Modified Gait Support in Adults Three to Eighteen Months After Concussion"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5157-9265","authenticated-orcid":false,"given":"Tyler A.","family":"Wood","sequence":"first","affiliation":[{"name":"College of Health and Human Sciences, School of Rehabilitation and Performance Sciences, Northern Illinois University, DeKalb, IL 60115, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5649-2006","authenticated-orcid":false,"given":"Nicholas E.","family":"Grahovec","sequence":"additional","affiliation":[{"name":"College of Health and Human Sciences, School of Rehabilitation and Performance Sciences, Northern Illinois University, DeKalb, IL 60115, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,7,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"695","DOI":"10.1136\/bjsports-2023-106898","article-title":"Consensus statement on concussion in sport: The 6th international conference on concussion in sport-amsterdam, October 2022","volume":"57","author":"Patricios","year":"2023","journal-title":"Br.
