Fifteen National Collegiate Athletic Association (NCAA) Division 1 football players underwent DTI of the cervical spinal cord (vertebral level C1\u20134) at pre-season (before any contact practices began) and post-season (within 1 week of the last regular season game) intervals. Helmet accelerometer data were also collected in parallel throughout the season. From pre-season to post-season, a significant decrease (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u20090.05) of axial diffusivity was seen within the right spino-olivary tract. In addition, a significant decrease (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u20090.05) in global white matter fractional anisotropy (FA) along with increases (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u20090.05) in global white matter mean diffusivity (MD) and radial diffusivity (RD) were found. These changes in FA from pre-season to post-season were significantly moderated by previous concussion history (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u20090.05) and number of HAEs over 80 g (\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u20090.05). Despite the absence of sports-related concussion (SRC), we present measurable changes in the white matter integrity of the cervical spinal cord suggesting injury from repetitive HAEs, or SRC, may include the entirety of the CNS, not just the brain.\n                  <\/jats:p>","DOI":"10.1089\/neur.2020.0035","type":"journal-article","created":{"date-parts":[[2021,2,18]],"date-time":"2021-02-18T15:47:44Z","timestamp":1613663264000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":4,"title":["Changes in White Matter of the Cervical Spinal Cord after a Single Season of Collegiate Football"],"prefix":"10.1177","volume":"2","author":[{"given":"Brian","family":"Johnson","sequence":"first","affiliation":[{"name":"Department of Radiology, University of Texas Southwestern Medical Center, Dallas, Texas, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexa E.","family":"Walter","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, The Pennsylvania State University, University Park, Pennsylvania, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"James R.","family":"Wilkes","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, The Pennsylvania State University, University Park, Pennsylvania, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Linda","family":"Papa","sequence":"additional","affiliation":[{"name":"Department of Emergency Medicine, Orlando Regional Medical Center, Orlando, Florida, USA."},{"name":"Department of Neurology and Neurosurgery, McGill University, Montreal, Quebec, Canada."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Semyon M.","family":"Slobounov","sequence":"additional","affiliation":[{"name":"Department of Kinesiology, The Pennsylvania State University, University Park, Pennsylvania, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,2,18]]},"reference":[{"key":"e_1_3_5_2_2","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2017-097699"},{"key":"e_1_3_5_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/JSM.0b013e318295bbb1"},{"key":"e_1_3_5_4_2","doi-asserted-by":"publisher","DOI":"10.1089\/neu.2007.0331"},{"key":"e_1_3_5_5_2","doi-asserted-by":"publisher","DOI":"10.1089\/jwh.2018.7282"},{"key":"e_1_3_5_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jmpt.2008.11.014"},{"key":"e_1_3_5_7_2","first-page":"1590161","article-title":"Cervical spine involvement in mild traumatic brain injury: a review","volume":"2016","author":"Morin M.","year":"2016","unstructured":"Morin M., , Langevin P., , and Fait P.
