    ABSTRACT: To examine the effect of soccer heading ball speed on S-100B serum concentration, concussion sideline assessments and linear head impact acceleration. Sixteen division I soccer players participated in this pre-test post-test design study. Athletes performed five standing headers over a 10 minute period at 30 (n = 5), 40 (n = 5) or 50 (n = 6) miles per hour (mph) (randomized). S-100B serum concentration (ng mL(-1)) and sideline concussion assessments were measured prior to and post-heading. Peak resultant linear head acceleration (gravitational units; g) was measured during soccer heading. No statistically significant interaction effects were identified between ball velocity groups over time on S100B (effect sizes ranged from 0.03-0.23) or concussion assessments tests. There was a non-significant increase (p = 0.06) in head impact acceleration from the 30 (30.6; SD = 6.2 g) to 50 mph (50.7; SD = 7.7 g) ball speed. In this controlled setting, an acute bout of soccer heading across various ball velocities did not affect S100B or concussion assessment test scores. These findings are preliminary, as the small sample size in each group may have played a role in the lack of significant findings.

    ABSTRACT: Information is scant concerning enduring brain injury effects of participation in the contact sport of Rugby Union (hereafter rugby) on early adolescents. The objective was prospectively to investigate differences between young adolescent male rugby players and non-contact sports controls on neurocognitive test performance over 3 years and academic achievement over 6 years. A sample of boys from the same school and grade was divided into three groups: rugby with seasonal concussions (n = 45), rugby no seasonal concussions (n = 21) and non-contact sports controls (n = 30). Baseline neurocognitive testing was conducted pre-season in Grade 7 and post-season in Grades 8 and 9. Year-end academic grades were documented for Grades 6-9 and 12 (pre-high school to year of school leaving). A mixed model repeated measures ANOVA was conducted to investigate comparative neurocognitive and academic outcomes between the three sub-groups. Compared with controls, both rugby groups were significantly lower on the WISC-III Coding Immediate Recall sub-test. There was a significant interaction effect on the academic measure, with improved scores over time for controls, that was not in evidence for either rugby group. Tentatively, the outcome suggests cognitive vulnerability in association with school level participation in rugby.

    ABSTRACT: To describe differences in outpatient follow-up and academic accommodations received by children with and without persistent post-concussion symptoms (PPCS) after emergency department (ED) evaluation. It was hypothesized that children with PPCS would have more outpatient visits and receive academic accommodations more often than children without PPCS and that follow-up would be positively associated with receiving accommodations. Children aged 8-18 years with acute (≤6hours) concussion at time of presentation to a paediatric ED were enrolled in an observational study. Outcomes were assessed through a telephone survey 30 days after injury. Of 234 enrolled participants, 179 (76%) completed follow-up. PPCS occurred in 21%. Only 45% of subjects had follow-up visits after ED discharge. Follow-up visit rates were similar for those with and without PPCS (58% vs. 41%, respectively; p = 0.07). Children with PPCS missed twice as many school days as those without (3 vs. 1.5; p < 0.001), but did not differ in receiving academic accommodations (36% vs. 53%; p = 0.082). Outpatient follow-up was associated with receiving academic accommodations (RR = 2.2; 95% CI = 1.4-3.5). Outpatient follow-up is not routine for concussed children. Despite missing more school days, children with PPCS do not receive academic accommodations more often. Outpatient follow-up may facilitate academic accommodations.

    ABSTRACT: Participation is considerably restricted in children and adolescents with acquired brain injury (ABI) as compared to their healthy peers. This systematic review aims to identify which factors are associated with participation in children and adolescents with ABI. A systematic search in Medline and various other electronic databases from January 2001-November 2014 was performed. All clinical studies describing determinants of participation at least 1 year after the diagnosis of ABI by means of one or more pre-defined instruments in patients up to 18 years of age were included. Extracted data included study characteristics, patient characteristics, participation outcome and determinants of participation (categorized into: health conditions (including characteristics of ABI), body functions and structures, activities, personal factors and environmental factors). The methodological quality of the studies was evaluated based on three quality aspects (selection, information and statistical analysis bias) and scored as low, moderate or high. Eight studies using an explicit participation outcome measure were selected after review, including a total of 1863 patients, with a follow-up ranging from 1 up to 288 months. Three studies included patients with a traumatic or a non-traumatic brain injury (TBI or NTBI) and five studies with only TBI patients. Factors consistently found to be associated with more participation restrictions were: greater severity of ABI, impaired motor, cognitive, behavioural and/or sensory functioning, limited accessibility of the physical environmentand worse family functioning. Fewer participation problems were associated with a supportive/nurturing parenting style, higher household income, acceptance and support in the community and availability of special programmes. The overall methodological quality of the included studies was high in two and moderate in six studies. This systematic review shows that only a few, moderate quality, studies on the determinants of participation after paediatric ABI using recommended explicit measurement instruments are available. Various components of the ICF model: health condition, body functions and structures and environmental factors were consistently found to be associated with participation. More methodologically sound studies, using the recommended explicit outcome measures, a standardized set of potential determinants and long-term follow-up are suggested to increase the knowledge on participation in children and youth with ABI.

    ABSTRACT: To extend previous observations by investigating if differences exist in time to initiation or to recovery of total oral intake in patients with acquired brain injury assessed by either Facial-Oral Tract Therapy (F.O.T.T.®) or Fibreoptic Endoscopic Evaluation of Swallowing (FEES) and to investigate whether other factors influence these outcomes. Randomized controlled trial. One hundred and nineteen patients with dysphagia in inpatient neurorehabilitation were randomized. The main outcome was time to maximum on the Functional Oral Intake Scale. There was no difference in time to initiation or recovery of total oral intake using F.O.T.T.® or FEES. Oral intake was initiated for 42% on admission and 92% at discharge; 2.5% of the patients were on total oral intake within 24 hours of admission and 37% at discharge. The likelihood of recovery to total oral intake before discharge was found to depend on age, Functional Independence Measure score, length of stay and number of dysphagia interventions. There was no significant difference in time to initiation and recovery of total oral intake before discharge, whether assessed by F.O.T.T.® or FEES, indicating that an instrumental assessment is unnecessary for standard evaluation. Age, functional independence and length of stay had a significant influence.

    ABSTRACT: This preliminary investigation studies selected aspects of validity of the Upper Limb Performance Analysis (ULPA), an occupation-based functional upper limb (UL) measure. The study investigated the ULPA-Task Performance Mastery (ULPA-TPM) in 35 community dwelling adults with upper motor neuron syndrome following acquired brain injury and 26 healthy controls. Construct and concurrent validity of the ULPA were determined via group discrimination between adults with and without ABI; and ABI participants who were and were not referred for UL spasticity management with botulinum toxin-A injections (injected and non-injected group). Concurrent validity was examined by investigating the relationships between the ULPA and an existing functional UL measure, the Action Research Arm Test, using Spearman's rank-order correlation. Significant differences in UL performance were demonstrated between the ABI and the Control group on all ULPA sub-scales (including: Omission (z = -2.6 to -3.6, rspb = 0.37-0.48), Accuracy (z = -5.8 to -6.0, rspb = 0.78-0.82), Repetition (z = -5.1 to -5.4, rspb = 0.63-0.73) and Timing errors (z = -5.9 to -6.2, rspb = 0.77-0.88). Those in the Injected group demonstrated more task performance errors than the Non-injected group, with significant differences in Accuracy (z = -2.1 to -2.4, rspb = 0.37-0.45), Repetition (z = -2.5 to -2.1, rspb = 0.43) and Timing (z = -2.0, rspb = 0.37). This study demonstrated good construct and concurrent validity of the ULPA-TPM.

    ABSTRACT: To characterize and identify trends in sports-related traumatic brain injury (TBI) emergency department (ED) visits from 2006-2011. This study reviewed data on sports-related TBI among individuals under age 65 from the Nationwide Emergency Department Sample from 2006-2011. Visits were stratified by age, sex, injury severity, payer status and other criteria. Variations in incidence and severity were examined both between groups and over time. Odds of inpatient admission were calculated using regression modelling. Over the period examined, 489 572 sports-related TBI ED visits were reported. The majority (62.2%) of these visits occurred among males under the age of 18. The average head Abbreviated Injury Severity score among these individuals was 1.93 (95% CI = 1.93-1.94) and tended to be lowest among those in middle school and high school age groups; these were also less likely to be admitted. The absolute annual number of visits grew 65.9% from 2006 until 2011, with the majority of this growth occurring among children under age 15. Hospitalization rates dropped 35.6% over the same period. Changes in year-over-year presentation rates vs. hospitalization rates among young athletes suggest that players, coaches and parents may be more aware of sports-related TBI and have developed lower thresholds for seeking medical attention.

    ABSTRACT: To investigate trajectories and predictors of trajectories of anxiety and depression in relatives of patients with a severe brain injury during the first year after injury. A prospective longitudinal study with four repeated measurements. Ninety relatives of patients with severe brain injury. The relatives were assessed on the anxiety and depression scales from the Symptom Checklist-90-Revised and latent variable growth curve models were used to model the trajectories. The effects of patient's age, patient's Glasgow Coma Score, level of function and consciousness, gender and relationship of the relatives were modelled. Improvement was found in both symptoms of anxiety and depression during the 12-month study period. The analysis revealed different trajectories for symptoms of anxiety and depression, as anxiety had a more rapid improvement. Higher initial level of symptoms of depression was seen in female relatives. Higher initial level of anxiety was associated with younger patient age, lower level of function and consciousness in the patient and the relative being female or the spouse. Future research and interventions should focus not only on specific deficits in the patient, but also on how the emotional state and well-being of the relatives evolve, while trying to adjust and cope with a new life-situation.

    ABSTRACT: The aim of this study was to examine community integration by the Community Integration Questionnaire (CIQ) 2 years after injury in a divided TBI sample of moderately and severely injured patients. The second aim was to identify social-demographic, injury-related and rehabilitation associated predictors of CIQ. A cohort study. Outpatient follow-up. Fifty-seven patients with moderate (n = 21) or severe (n = 36) TBI were examined with the Community Integration Questionnaire (CIQ) at 2 years after injury. Possible predictors were analysed in a regression model using CIQ total score at 2 years as the outcome measure. The Community Integration Questionnaire. At 2 years follow-up, there was significant difference between the moderately and severely injured patients in the productivity scores (p < 0.003), while difference in the total CIQ scores approached the significance level (p = 0.074). Significant predictors of a higher CIQ score were living with a spouse, higher Glasgow Coma Scale (GCS) in the acute phase, shorter Post-Traumatic Amnesia (PTA), longer rehabilitation stay (LOS) and use of rehabilitation service. Use of rehabilitation service (B = 7.766) and living with a spouse (B = 4.251) had the largest influence. This means that living with a spouse, better score on the GCS scale, shorter PTA, longer LOS and use of rehabilitation service after discharge equated to better community integration 2 years after TBI Conclusions: Two years after TBI the moderately injured patients have a higher productivity level than the severely injured patients. Marital status, injury severity and rehabilitation after injury were associated with community integration 2 years after TBI.

    ABSTRACT: Primary objective and hypothesis: To test the hypothesis that there is a significant relationship between WeeFIM ratings of cognitive functioning and performance on neuropsychological tests of children with traumatic brain injury (TBI). Retrospective analysis of archival data. Data from 52 children with severe TBI collected during inpatient rehabilitation. Multiple regression analysis with Neuropsychological test scores from Wechsler Abbreviated Scale of Intelligence (WASI) and Children's Memory Scale (CMS) entered as predictor variables and WeeFIM cognitive ratings as criteria variables. Analyses revealed significant relationships between WeeFIM cognitive rating and neuropsychological test scores. Delayed verbal memory was most highly associated with WeeFIM cognitive ratings. Results support the hypothesis of significant relationships between neuropsychological performance and WeeFIM ratings of children with TBI and support generalizability of neuropsychological performance to daily cognitive functioning.

    ABSTRACT: This prospective longitudinal study aimed to identify rates and predictors of productivity outcomes (educational or vocational) at 1 year post-injury in young people studying prior to sustaining a traumatic brain injury (TBI). A total of n = 145 with complicated mild-severe injuries, studying at secondary (45.2%) or tertiary (54.8%) levels pre-injury, participated. Mean age at injury = 18.6 years (SD = 3.29) and mean duration of PTA = 21.9 days (SD = 27.18). Pre-injury demographic (gender, age, level of study, living situation), injury related (severity, physical injuries) and concurrent post-injury (independence in ADLs and self-reported cognitive, behavioural, emotional sequelae) predictors were entered into logistic regressions. Of those participants categorized as 'productive' (79.3%), 60% were studying, with 40% employed. Participants with longer PTA and those with reduced initiative and self-centredness were less likely to be 'productive'. The overall relationship between PTA and productivity appeared to be linear in nature, with PTA duration of more than 80 days, reducing the probability of being productive at 1 year to 50%. PTA duration and behavioural sequelae were the strongest predictors of productivity in those studying prior to injury. Allied health supports should be targeted towards reducing the impact of and compensating for barriers such as reduced initiative in order to maximize productive outcomes in this group.

    ABSTRACT: To characterize an acute stress reaction (ASR) following an improvised explosive device (IED) blast-related mild traumatic brain injury (mTBI). Participants were male, US military personnel treated in Afghanistan within 4 days following an IED-related mTBI event (n = 239). Demographics, diagnosis of ASR, injury history and self-reported mTBIs, blast exposures and psychological health histories were recorded. In total, 12.5% of patients met ASR criteria. Patients with ASR were significantly younger and junior in rank (p < 0.05). Patients with ASR were more likely to experience the IED-blast while dismounted, report a loss of consciousness (LOC) and higher pain levels (p < 0.05). Adjusting for age and rank, multivariate logistic regression showed an association between mTBI history and ASR (AOR = 1.405; 95% CI = 1.105-1.786, p < 0.01). Adjusting for mechanism of injury (dismounted vs. mounted), LOC and pain, multivariate logistic regression showed an association between mTBI history and ASR (AOR = 1.453; 95% CI = 1.132-1.864, p < 0.01). Prior blast exposure and past psychological health issues were not associated with ASR. A history of multiple mTBIs is associated with increased risk of ASR. Future research is warranted.

    ABSTRACT: Fall is a common mechanism of injury (MOI) in young children and an important risk factor for traumatic brain injury (TBI). Most children who fall have a minor head injury (MHI), defined as a blunt head trauma that occurred in a patient who is conscious and responsive. To seek a possible association between MOI and injury severity. A single centre cohort study was conducted. Data were collected on patients aged 0-2 years with MHI. Clinically-significant TBI (csTBI), defined as head injury resulting in death, intubation or neurosurgery, was the primary outcome measure. Traumatic finding on CT scan (TFCT) was the secondary outcome measure. Five hundred and ninety-five patients were analysed. Eight types of falls were identified: from ground-level, down stairs, from a bed, from a changing table, from furniture, from adult-hold, from a playground-device and from a stroller/baby-carriage. One patient (0.16%) had csTBI. Thirty-one (5.2%) underwent CT scans, TFCT was diagnosed in 17 (2.8%) patients; 10 (1.7%) linear skull-fractures, two (0.3%) depressed skull-fractures and five (0.8%) intracranial haemorrhages. Regression analysis did not reveal a statistically significant association between any of the MOI and the presence of TFCT. The risk for csTBI was low and no association was found between MOI and injury severity.

    ABSTRACT: This article explores the challenges, support needs and coping strategies of caregivers of people with an acquired brain injury (ABI). Semi-structured interviews were conducted with caregivers (n = 20) to explore their support services received, access barriers, utility of services, needed supports, coping strategies and factors promoting life satisfaction. The team recorded, transcribed verbatim and inductively analysed all interviews. Through thematic data analysis, three central themes were revealed: (a) barriers impeding quality-of-life, (b) support needed to improve quality-of-life and (c) factors enabling quality-of-life. All perspectives from the participants involved are synthesized to provide a rich depiction of caregivers' support needs and coping strategies. Two specific findings of interest include a negative association between severity of brain injury and caregiver's desire to direct treatment, as well as a distinct service gap in assistance for caregivers who are caring for someone with violent/offending behaviours. This study recommends short- and long-term changes, given Australia's upcoming National Disability Insurance Scheme, to increase caregiver quality-of-life, which will ultimately affect the rehabilitation outcomes of persons with ABI.

    ABSTRACT: Visinin-like protein-1 (VILIP-1) has shown potential utility as a biomarker for neuronal injury in cerebrospinal fluid. This study investigated serum VILIP-1 as a diagnostic and prognostic marker in sports-related concussion. This multi-centre prospective cohort study involved the 12 teams of the professional ice hockey league in Sweden. A total of 288 players consented to participate in the study. Thirty-five players sustained concussions, of whom 28 underwent repeated blood samplings at 1, 12, 36 and 144 hours after the trauma or when the player returned to play (7-90+ days). The highest levels of VILIP-1 were measured 1 hour after concussion and the levels decreased during rehabilitation, reaching a minimum level at the 36-hour sampling. However, the levels of serum VILIP-1 at 1 hour after concussion were not significantly higher than pre-season baseline values. Serum levels of VILIP-1 1 hour post-concussion did not correlate with the number of days for the concussion symptoms to resolve. Further, serum levels of VILIP-1 increased after a friendly game in players who were not concussed. These results provide evidence that serum VILIP-1 may not be a useful biomarker for diagnosis and prognosis of sports-related concussion.

    ABSTRACT: Data from the World Health Organization estimates the global incidence of traumatic brain injury resulting in hospitalization or mortality to be close to 10 million people each year. People who sustain a blast-related TBI are more likely to sustain visual impairment than people injured by other means. There is a lack of published literature regarding the most effective means to assist a patient's recovery from TBI with new vision loss. The aim of this report is to describe the physical therapy management of a person regaining functional mobility when newly blind following a blast-related TBI. This case report describes the inpatient rehabilitation physical therapy (PT) services provided for a single subject who experienced a blast-related TBI with complete vision loss. The subject spent 3.5 weeks in IPR and participated in 21 PT sessions before being discharged home. Improvements in cognition, transfers and functional mobility with adaptations for vision loss were achieved, as well as caregiver training, to provide 24-hour supervision in the home. Collaborating with a blind specialist teacher assisted the rehabilitation of this subject. Further research is needed regarding the effective interventions for those with TBI and vision loss.

    ABSTRACT: Each year, more than 1.7 million Americans suffer a traumatic brain injury (TBI) and the lifetime prevalence of major depressive disorder following TBI is between 25-50%. There are no validated established strategies to treat TBI depression. Repetitive transcranial magnetic stimulation (rTMS) is a novel putative treatment option for post-TBI depression, which, compared with standard pharmacological agents, may provide a more targeted treatment with fewer side-effects. However, TBI is associated with an increased risk of both early and late spontaneous seizures, a significant consideration in evaluating rTMS as a potential treatment for TBI depression. Whilst the risk of seizure from rTMS is low, underlying neuropathology may somewhat increase that risk. This review focuses on the safety aspects of rTMS in TBI patients. The authors review why low frequency rTMS might be less likely to trigger a seizure than high frequency rTMS and propose low frequency rTMS as a safer option in TBI patients. Because there is little data on the safety of rTMS in TBI, the authors also review the safety of rTMS in patients with other brain pathology. It is concluded that pilot safety and tolerability studies should be first conducted in persons with TBI and neuropsychiatric comorbidities. These results could be used to help design larger randomized controlled trials.
