However, methodological limitations in the extant literature limit our understanding of the role of SWD in SRC. This study examined the association between acute\/subacute SRC and two sleep behaviors\u2014sleep duration and efficiency\u2014as measured by self-report and commercially available actigraphy (CA) in a sample of football players enrolled in a larger prospective longitudinal study of concussion. Fifty-seven high school and Division 3 male football players with SRC (mean [M] age\u2009=\u200918.00 years, standard deviation [SD]\u2009=\u20091.44) and 26 male teammate controls (M age\u2009=\u200918.54 years, SD\u2009=\u20092.21) were enrolled in this prospective pilot study. Sleep duration and sleep efficiency were recorded nightly for 2 weeks (starting 24\u201348\u2009h post-injury in the SRC group) via CA and survey delivered via mobile application. There was no significant relationship between SRC and objectively recorded sleep measures, a null finding. However, the SRC group reported a brief (3-day) reduction in sleep efficiency after injury (M SRC\u2009=\u200982.18, SD\u2009=\u200912.24; M control\u2009=\u200989.2, SD\u2009=\u20094.25;\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u20090.013; Cohen's\n                    <jats:italic toggle=\"yes\">d<\/jats:italic>\n                    \u2009=\u20090.77), with no change in sleep duration. Self-reported and actigraph-assessed hours of sleep were weakly and insignificantly correlated in the SRC group (\n                    <jats:italic toggle=\"yes\">r<\/jats:italic>\n                    \u2009=\u2009\u22120.21,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u20090.145), whereas they were robustly correlated in the non-injured control group (\n                    <jats:italic toggle=\"yes\">r<\/jats:italic>\n                    \u2009=\u20090.65,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009=\u20090.004). SWD post-SRC was not observed in objectively measured sleep duration or sleep efficiency and was modest and time-limited based on self-reported sleep efficiency. The weak correlation between self-reported and objective sleep behavior measures implies that subjective experience of SWD post-SRC may be due to factors other than actual changes in these observable sleep behaviors. Clinically, SWD in the early-subacute stages of recovery from SRC may not be adequately measurable via current CA. Subjective SWD may require alternative methods of evaluation (e.g., clinical actigraph or sleep study).\n                  <\/jats:p>","DOI":"10.1089\/neur.2021.0008","type":"journal-article","created":{"date-parts":[[2021,4,27]],"date-time":"2021-04-27T00:15:23Z","timestamp":1619482523000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":8,"title":["Relationship between Sport-Related Concussion and Sleep Based on Self-Report and Commercial Actigraph Measurement"],"prefix":"10.1177","volume":"2","author":[{"given":"Ciaran M.","family":"Considine","sequence":"first","affiliation":[{"name":"Department of Neurology, Vanderbilt University Medical Center, Nashville, Tennessee, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Daniel L.","family":"Huber","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Medical College of Wisconsin, Milwaukee Wisconsin, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Niemuth","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Medical College of Wisconsin, Milwaukee Wisconsin, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Danny","family":"Thomas","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, Medical College of Wisconsin, Milwaukee Wisconsin, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael A.","family":"McCrea","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Medical College of Wisconsin, Milwaukee Wisconsin, USA."},{"name":"Department of Neurology, Medical College of Wisconsin, Milwaukee Wisconsin, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lindsay D.","family":"Nelson","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Medical College of Wisconsin, Milwaukee Wisconsin, USA."},{"name":"Department of Neurology, Medical College of Wisconsin, Milwaukee Wisconsin, USA."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2021,4,26]]},"reference":[{"key":"e_1_3_4_2_2","unstructured":"World Health Organization.
