Recovery time (days) and protracted recovery (&gt;30\u2009days) were the primary outcomes. Multivariable regression models were used to evaluate the association between VOMS symptom provocation and (1) recovery time (days) and (2) protracted recovery. Measures of VOMS validity, predictive ability and receiver operator curves were used to assess VOMS as a prognostic tool to accurately classify a normal\/protracted recovery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>After adjustment, any symptom provocation across all VOMS domains was associated (p&lt;0.05) with greater recovery time, except the convergence test (p=0.08) in females. All VOMS test thresholds (\u22651\u2009to \u226510) in males and (\u22651\u2009to \u22655) in females were associated (p&lt;0.05) with recovery time. However, the VOMS test performed poorly among males (receiver operating characteristic (ROC) area=0.66) and failed among females (ROC area=0.56) as a prognostic tool to identify those that will have a normal\/protracted recovery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>In this sample, overall, the VOMS test was associated with recovery time (days); however, the VOMS was not a valid stand-alone prognostic tool to identify a delayed recovery, but may be useful in combination with other concussion symptomology assessments. Future studies should confirm these findings in larger samples while taking into consideration other comorbid factors that may influence recovery time.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1136\/bmjsem-2020-000970","type":"journal-article","created":{"date-parts":[[2022,10,25]],"date-time":"2022-10-25T15:01:31Z","timestamp":1666710091000},"page":"e000970","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":22,"title":["Evaluation of the vestibular and ocular motor screening (VOMS) as a prognostic tool for protracted recovery following paediatric sports-related concussion"],"prefix":"10.1136","volume":"7","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5067-544X","authenticated-orcid":false,"given":"Gregory","family":"Knell","sequence":"first","affiliation":[{"name":"Center for Pedatric Population Health, Children's Health System of Texas and University of Texas Health Science Center at Houston, Dallas, TX, USA"},{"name":"Epidemiology, Human Genetics, and Environmental Sciences, University of Texas Health Science Center at Houston, Dallas, TX, USA"},{"name":"Andrews Institute for Orthopaedics and Sports Medicine, Children's Health System of Texas, Plano, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Todd","family":"Caze","sequence":"additional","affiliation":[{"name":"Andrews Institute for Orthopaedics and Sports Medicine, Children's Health System of Texas, Plano, TX, USA"},{"name":"Department of Psychiatry, University of Texas Southwestern Medical School, Dallas, Texas, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott O","family":"Burkhart","sequence":"additional","affiliation":[{"name":"Andrews Institute for Orthopaedics and Sports Medicine, Children's Health System of Texas, Plano, TX, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2021,3,25]]},"reference":[{"key":"2025083109443831000_7.1.e000970.1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2017-097699"},{"key":"2025083109443831000_7.1.e000970.2","doi-asserted-by":"crossref","DOI":"10.1542\/peds.2015-4635","article-title":"Sports- and Recreation-Related concussions in US youth","volume":"138","author":"Bryan","year":"2016","journal-title":"Pediatrics"},{"key":"2025083109443831000_7.1.e000970.3","doi-asserted-by":"crossref","first-page":"396","DOI":"10.1177\/0363546517738742","article-title":"Effects of the New York State Concussion Management and Awareness Act (\"Lystedt Law\") on Concussion-Related Emergency Health Care Utilization Among Adolescents, 2005-2015","volume":"46","author":"Baker","year":"2018","journal-title":"Am J Sports Med"},{"key":"2025083109443831000_7.1.e000970.4","doi-asserted-by":"crossref","first-page":"163","DOI":"10.1001\/jamapediatrics.2014.2320","article-title":"Analyzing the effect of state legislation on health care utilization for children with concussion","volume":"169","author":"Gibson","year":"2015","journal-title":"JAMA Pediatr"},{"key":"2025083109443831000_7.1.e000970.5","unstructured":"Green L .
