They did not differ from controls on other clinical outcome measures. There were no differences in cortical thickness between the groups. Professional players had smaller whole brain (p = .003), bilateral hippocampi (ps = .03), and left amygdala volumes (p = .01) compared to healthy controls. Within the players group, there were significant associations between greater alcohol use and smaller bilateral hippocampi and left amygdala volumes. There were no associations between structural volumes and history of concussions or memory performance. Conclusions: The literature examining cortical thickness in athletes with a history of multiple concussions is mixed. We did not observe differences in cortical thickness in professional rugby league players compared to controls. However, smaller subcortical volumes were found in players that were, in part, associated with greater alcohol consumption.]]> Tue 20 Sep 2022 10:48:22 AEST ]]> National rugby league match scheduling and rate of concussion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37702 Tue 16 Mar 2021 18:05:52 AEDT ]]> The epidemiology of sport-related concussion: what the rehabilitation clinician needs to know https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:41923 Tue 16 Aug 2022 09:09:24 AEST ]]> Chronic traumatic encephalopathy neuropathology might not be inexorably progressive or unique to repetitive neurotrauma https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48321 Tue 14 Mar 2023 16:19:38 AEDT ]]> Cortical thickness and subcortical brain volumes in professional rugby league players. https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:43132 Tue 13 Sep 2022 15:07:23 AEST ]]> Effects of exercise on Sport Concussion Assessment Tool-Third Edition performance in professional athletes https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:34340 Tue 03 Sep 2019 18:31:33 AEST ]]> The use of sideline video review to facilitate management decisions following head trauma in Super Rugby https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33782 Tue 03 Sep 2019 18:19:06 AEST ]]> 3D biomechanics of rugby tackle techniques to inform future rugby research practice: a systematic review https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:38088 Tue 03 Aug 2021 18:28:58 AEST ]]> A systematic review of potential long-term effects of sport-related concussion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:30362 Thu 28 Oct 2021 13:02:41 AEDT ]]> Tackle Risk Factors for Head Injury Assessments (HIAs) in Sub-Elite Rugby League and Recommendations for Prevention: Head Contacts from Upright Tackles Increase the HIA Risk to Both Ball Carrier and Tackler https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:56055 Thu 25 Jul 2024 08:15:11 AEST ]]> Tacklers' shoulder abduction and flexion at contact alter when engaging in different front-on, one-on-one tackle instructions from an expert coach https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:56056 Thu 25 Jul 2024 08:08:51 AEST ]]> Usefulness of video review of possible concussions in National Youth Rugby League https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32340 Thu 24 May 2018 10:50:09 AEST ]]> MR spectroscopy findings in retired professional rugby league players https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32339 Thu 24 May 2018 10:50:05 AEST ]]> Video and clinical screening of national rugby league players suspected of sustaining concussion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:32338 Thu 24 May 2018 10:49:58 AEST ]]> Systematic Review of Pre-injury Migraines as a Vulnerability Factor for Worse Outcome Following Sport-Related Concussion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51858 Thu 21 Sep 2023 09:41:25 AEST ]]> Systematic review of preinjury mental health problems as a vulnerability factor for worse outcome after sport-related concussion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:37497 Thu 21 Jan 2021 17:11:20 AEDT ]]> White matter abnormalities in retired professional rugby league players with a history of concussion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39028 n = 11) with a history of multiple self-reported concussions compared with age- and education-matched controls (n = 13) who have had no history of brain trauma. Diffusion-weighted images were acquired with a Siemens 3T scanner. All participants completed a clinical interview. There were no significant differences between groups on measures of depression, anxiety, stress, or post-concussion symptoms; however, NRL players scored significantly higher on the alcohol use disorder identification test (AUDIT). Voxelwise analyses of DTI measures were performed using tract-based spatial statistics (TBSS) with age and AUDIT scores included as covariates. TBSS revealed significantly reduced fractional anisotropy (FA), and increased radial diffusivity (RD), axial diffusivity (AD), and trace (TR) in white matter regions of recently retired NRL players compared with controls. FA was significantly reduced in the right superior longitudinal fasciculus and right corticospinal tract while TR, RD, and AD were increased in these regions, as well as the corpus callosum, forceps major, right uncinate fasciculus, and left corticospinal tract. In summary, DTI in a small cohort of recently retired professional NRL players with a history of multiple concussions showed differences in white matter microstructure compared with age- and education-matched controls with no history of brain trauma.]]> Thu 21 Apr 2022 15:32:34 AEST ]]> Incidence of Concussion and Time to Return-to-Play in the National Rugby League https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:48417 Thu 16 Mar 2023 14:10:52 AEDT ]]> Reliability of using the proposed international consensus video signs of potential concussion for national rugby league head impact events https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39611 Thu 16 Jun 2022 10:15:01 AEST ]]> Tacklers' Head Inertial Accelerations Can Be Decreased by Altering the Way They Engage in Contact with Ball Carriers' Torsos https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53753 Thu 11 Jan 2024 12:22:15 AEDT ]]> Cerebrovascular reactivity assessed by transcranial Doppler ultrasound in sport-related concussion: a systematic review https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:26978 Sat 24 Mar 2018 07:26:58 AEDT ]]> Systematic review of multivariable prognostic models for mild traumatic brain injury https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:28122 Sat 24 Mar 2018 07:24:59 AEDT ]]> A prospective investigation of changes in the sensorimotor system following sports concussion.

Testing was completed by the medical staff. Normative reference values were calculated for the components of the SCAT5, including the Standardized Assessment of Concussion, modified Balance Error Scoring System, and the Symptom Scale. A small case series of players who sustained concussions were included to illustrate the use of the new normative data. Results: The median Standardized Assessment of Concussion total score was 27.0 (M = 26.9, SD = 2.1). The median modified Balance Error Scoring System score was 2.0 (M = 2.4, SD = 2.2). The median number of symptoms score was 1.0 (M = 3.2, SD = 4.7) and the median symptom severity score was 2.0 (M = 5.4, SD = 8.2). The most common baseline symptom was fatigue or low energy (33%), followed by trouble sleeping (24%), headache (23%), neck pain (22%), and difficulty remembering (21%). In the total sample, 41% reported no symptoms. The clinical interpretation of these new normative data to a case series of women with concussions is provided. Conclusions: Normative reference values are provided for the SCAT5 for women who are professional rugby league players. Using these normative data will improve clinical interpretation of SCAT5 scores following a concussion.]]> Fri 28 Oct 2022 14:22:30 AEDT ]]> Symptoms of traumatic encephalopathy syndrome are common in the US general population https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39813 Fri 24 Jun 2022 09:35:06 AEST ]]> Prevalence of chronic traumatic encephalopathy in the Sydney Brain Bank https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:51905 Fri 22 Sep 2023 10:10:51 AEST ]]> Objective clinical tests of dual-task dynamic postural control in youth athletes with concussion https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42173 Fri 19 Aug 2022 09:29:17 AEST ]]> Predictors and correlates of depression in retired elite level rugby league players https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:47232 Fri 16 Dec 2022 12:08:56 AEDT ]]> Comparison of dynamic response and maximum principal strain of diagnosed concussion in professional men’s rugby league https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50927 Fri 11 Aug 2023 16:01:02 AEST ]]> Traumatic brain injury results in cellular, structural and functional changes resembling motor neuron disease https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:33164 Fri 07 Sep 2018 16:40:24 AEST ]]> Functional connectivity changes in retired rugby league players: a data-driven functional magnetic resonance imaging study https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:39976 controls group contrast.
