    ABSTRACT: Primary objective: Brain injury survivors experience many transitions post-injury and it is important that they experience these in the most supportive and integrative ways possible. This study provided a group of chronic brain injury survivors the opportunity to share their insights and experience of residential transition and to suggest strategies to help maximize the transition experience and outcomes. Research design: This study used a qualitative design that consisted of semi-structured interviews. Methods and procedures: Twenty-one adults with chronic acquired brain injury residing in community-based supported group houses answered a series of scripted questions. Interviews were recorded and participant statements were transcribed and coded according to prospectively developed transition themes. Main outcomes and results: Participants discussed positive and negative insights and experiences regarding residential transitions. Themes of balance between support and independence, life purpose and transition to more or less structure were frequently addressed. Participants suggested caregiver-targeted strategies to facilitate successful transitions before, during and after a move. Conclusions: The insights and suggestions shared by this group of chronic acquired brain injury survivors add to already existing knowledge of post-injury residential transitions and strategies professional caregivers may use to maximize the ease and success of the survivor's transitional experience.

    ABSTRACT: Objective: This study evaluated the reliability and validity of a convenient method that uses the real-time feedback surface electromyography (sEMG) to control muscle activation while measuring the MEP recorded from the quadriceps muscle in patients with stroke. Methods: It measured the MEP parameters as well as the clinical assessment at initial test. Participants were directed to adjust their quadriceps contraction to extend the knee isometrically and maintain the EMG amplitude at 0.2 mV. MEPs were measured 2 weeks after the initial test again to assess the reliability of this measurement. Results: A good test-re-test reliability was demonstrated with an intra-class correlation coefficient (ICC) > 0.8 for the motor threshold and a moderate reliability (ICC > 0.6) for the MEP latency and MEP amplitude, for both paretic and non-paretic legs. Patients with present MEPs had significantly higher scores in muscle power, the Fugl-Meyer assessment, the balance sub-scale of performance-oriented mobility assessment and the Barthel index; and lower NIHSS scores than those of patients with absent MEPs (all p < 0.05). Conclusion: The sEMG-guided low level muscle activation is suitable for MEP assessment in patients with leg weakness after a stroke and may be used for long-term follow-up studies.

    ABSTRACT: Background: Traumatic-brain-injury (TBI) is a devastating-condition resulting in cerebral edema and ischemia. This study investigates the association of mild-TBI (mTBI) to sub-clinical atherosclerosis and cardiovascular (CV) mortality. Methods: Five hundred and forty-three veterans without known coronary artery disease or diagnosed mental disorder, who underwent coronary artery calcium (CAC) scanning for clinical indications, were followed for a median of 4-years. Veterans' medical diagnoses and neuropsychiatric health status (mTBI vs non-mTBI) were evaluated using VA electronic medical records. CAC was defined as 0, 1-100, 101-400 and 400+. Results: CAC was higher in mTBI, compared to without-mTBI (p < 0.05). TBI was more prevalent with the-severity of CAC (p < 0.05). Regression-analyses revealed that mTBI is an independent-predictor of CAC (p < 0.01). The CV mortality rate was 25% in mTBI and 10.5% in without-mTBI (p = 0.0001). Multivariable survival regression analyses revealed a significant-association between mTBI and CAC, with increased-risk of CV mortality (p < 0.05). The hazard-ratio of CV mortality was 5.25 in mTBI & CAC > 0, compared to without-mTBI & CAC = 0 (p < 0.05). The risk of CV-mortality was 2.25 for mTBI & CAC = 1-100, 4.93 for mTBI & CAC = 101-400 and 7.06 for mTBI & CAC ≥ 400, compared to matched CAC-categories without-mTBI (p < 0.05). The area under ROC curve to predict CV mortality was 0.64 for mTBI, 0.69 for mTBI & PTSD, 0.85 for mTBI & CAC > 0 and 0.92 for the combination. The prognostication of mTBI to predict CV mortality is superior to the Framingham risk score. Also the combination of mTBI & PTSD provided incremental prognostic values to predict CV mortality (p < 0.05). Conclusions: mTBI is associated with the severity of sub-clinical coronary atherosclerosis and independently predicts CV mortality.

    ABSTRACT: Introduction: Literature remains sparse regarding decompressive craniectomy (DC) in traumatic brain injury (TBI) in very young children. This study analysed the indications, complications and outcome of young children undergoing DC for TBI at our institute. Study design: Retrospective. Observations: The total number of patients was 71. Mean age was 1.6 years. Mean duration from injury to surgery was 11.9 hours (range = 3-80 hours). Around 50% had severe head injury. Intracranial pressure (ICP) monitoring was done in 33 patients. Mean ICP was 22.2 mm Hg (range = 9-50 mm Hg). The threshold ICP for surgery was 15 mm Hg. Perioperative mortality was 50% each for severe TBI (18/36) and diffuse cerebral edema (7/14), and 58% for infants (4/7). Ninety per cent of expired patients had ICP > 20 mm Hg. Mean follow-up duration was 19.6 months (range = 2-42 months). Except one, all survivors had good-to-excellent outcomes (Glasgow outcome scale extended; GOS-E = 7-8). Conclusions: Decompressive craniectomy offers a survival advantage in almost 50% of young children with severe TBI and should be used judiciously. The highest mortality was within the 1st week of surgery. The cut-off limit of 20 mm Hg for surgical decompression might not be applicable to young children and a low threshold ICP needs to be considered. Factors associated with increased mortality are high opening ICP (>20 mm Hg), GCS <8, diffuse cerebral oedema and infant age group. Timing of DC remains crucial. Further prospective studies are necessary to optimize the timing and ICP limit for surgical decompression.

    ABSTRACT: Primary objective: To explore experiences of pathways, outcomes and choice after motor vehicle accident (MVA) acquired severe traumatic brain injury (sTBI) under fault-based vs no-fault motor accident insurance (MAI). Methods: In-depth qualitative interviews with 10 adults with sTBI and 17 family members examined experiences of pathways, outcomes and choice and how these were shaped by both compensable status and interactions with service providers and service funders under a no-fault and a fault-based MAI scheme. Participants were sampled to provide variation in compensable status, injury severity, time post-injury and metropolitan vs regional residency. Interviews were recorded, transcribed and thematically analysed to identify dominant themes under each scheme. Results: Dominant themes emerging under the no-fault scheme included: (a) rehabilitation-focused pathways; (b) a sense of security; and (c) bounded choices. Dominant themes under the fault-based scheme included: (a) resource-rationed pathways; (b) pressured lives; and (c) unknown choices. Participants under the no-fault scheme experienced superior access to specialist rehabilitation services, greater surety of support and more choice over how rehabilitation and life-time care needs were met. Conclusions: This study provides valuable insights into individual experiences under fault-based vs no-fault MAI. Implications for an injury insurance scheme design to optimize pathways, outcomes and choice after sTBI are discussed.

    ABSTRACT: Objective: The relationship between moderate/severe traumatic brain injury (TBI) and cognitive deficits is well known. The nature, duration and predictors of cognitive difficulties post-mild TBI remain unclear. This study examined cognitive, mood and post-concussion outcomes of mild TBI over 1-year post-injury. Method: Adults (>15 years) with mild TBI (n = 260) completed neuropsychological (CNS-Vital Signs, Behavioural Dyscontrol Scale), mood (Hospital Anxiety Depression Scale) and behavioural assessments (Cognitive Failures Questionnaire, Rivermead Post-Concussion Questionnaire) at baseline, 1-, 6- and 12-months post-injury. Results: Over the 12-months post-injury self-reported cognition (p = 0.027), post-concussion symptoms (p < 0.001), depression (p < 0.001), anxiety (p < 0.001) and dyscontrol (p = 0.025) improved significantly. Assessments of memory, processing speed, executive function, psychomotor speed/reaction time, complex attention and flexibility also improved significantly. At baseline >20% of individuals produced very low scores on executive ability, complex attention and cognitive flexibility. At 1- and 6-month follow-ups >20% of participants were very low for complex attention, with 16.3% remaining so at 12-months. Executive abilities and speed were related to post-concussion symptoms, mood and self-reported cognition at 12-months. Conclusions: Whilst significant improvements were noted across measures over time, a significant proportion of individuals still perform poorly on neuropsychological measures 12-months after mild TBI; and these were linked to post-concussion symptoms, mood and self-reported cognitive outcomes. This implies a longer trajectory for recovery than has previously been suggested, which has implications for provision of assessment and rehabilitation services for more extended periods.

    ABSTRACT: Background: Long-term outcomes after TBI are examined to a large extent, but longitudinal studies with more than 1-year follow-up time after injury have been fewer in number. The course of recovery may vary due to a number of factors and it is still somewhat unclear which factors are contributing. Aim: The aim of this study was to describe the functional level at four time points up to 24 months after traumatic brain injury (TBI) and to evaluate the predictive impact of pre-injury and injury-related factors. Design: A cohort study. Setting: Outpatient. Population: Sixty-five patients with moderate (n = 21) or severe (n = 44) TBI. Methods: The patients with TBI were examined with Functional Independence Measure (FIM) and Glasgow Outcome Scale Extended (GOSE) at 3 months, 12 months and 24 months after injury. Possible predictors were analysed in a regression model using FIM total score at 24 months as the outcome measure. Results: FIM scores improved significantly from rehabilitation unit discharge to 24 months after injury, with peak levels at 3 and 24 months after injury (p < 0.001), for the whole TBI group and the group with severe TBI. The moderate TBI group did not show significant FIM score improvement during this time period. GOSE scores for the whole group and the moderate group improved significantly over time, but the severe group did not. FIM at admission to the rehabilitation unit and GCS score at admission to the rehabilitation unit were closest to being significant predictors of FIM total scores 24 months after injury (B = 0.265 and 2.883, R(2 )= 0.39, p = 0.073, p = 0.081). Conclusion: FIM levels improved during the period from rehabilitation unit discharge to 3 months follow-up; thereafter, there was a 'plateauing' of recovery. In contrast, GOSE 'plateauing' of recovery was at 12 months. Clinical rehabilitation impact: The study results may indicate that two of the most used outcome measures in TBI research are more relevant for assessment of the functional recovery in a sub-acute phase than in later stages of TBI recovery.

    ABSTRACT: Primary objective: The aim of this study is to assess if laser evoked potentials (LEPs) examination should be considered as an objective evidence of potential or residual pain perception capacity in vegetative (VS) and minimally conscious state (MCS) patients and if it could be a feasible methodology in order to differentiate these two clinical entities. Research design: This is a cross-sectional observational study focusing on the role of LEP examination, which is an easy and objective neurophysiological approach of the nociceptive system. Methods and procedures: Thirteen VS and 10 MCS patients were enrolled. All subjects were evaluated clinically by using validated behavioural scales and underwent to upper and lower limbs LEP recording. Main outcomes and results: Intra-group LEPs analysis in VS patients highlighted significant differences for N2P2 latency (p = 0.036) and amplitude (p = 0.018). Inter-group LEPs analysis showed significant differences in post-anoxic condition for N2P2 latency (p = 0.034), amplitude (p = 0.034) and a trend in N2P2 latency in brain trauma (p = 0.07). Interestingly, correlation analysis showed a significant relationship between N2P2 amplitude and Coma Recovery Scale-Revised scoring in the post-traumatic VS (r = 0.823, p = 0.044). Conclusions: The findings lead to detection of potential markers of conscious pain perception in patients with DOC, with important impact on therapeutic and rehabilitative management, and provide new information that may allow a better differential diagnosis.

    ABSTRACT: This study describes the case of a 57 year old gentleman with a previous severe brain injury who developed a severe psychotic disorder 19 years after the injury. This appears to have been precipitated by heavy psychedelic substance use, including cannabis, salvia divinorum, ketamine, LSD, cocaine and DMT amongst others. The psychosis remained in the absence of drug intoxication and was associated with prominent apathy, lack of concern and abulia. This study discusses the heavy psychedelic substance misuse possibly potentiating a transition to psychosis in this individual. Little work has been undertaken in this area as substance misuse has traditionally been an exclusion criteria for investigating psychosis in this patient group. It is suggested that psychedelic substance misuse should be investigated as a risk factor for psychotic illness in patients with brain injury, as this case clearly suggests.

    ABSTRACT: The goal of this investigation is to examine the prevalence of poor subjective sleep in patients with a history of mild traumatic brain injury (mTBI) and examine the relationship between subjective sleep quality and postconcussive symptoms (PCS), above and beyond the typical demographic and psychological distress variables. Individuals with a history of mTBI completed online questionnaires. Regression analysis was utilized to determine if subjective sleep quality would predict PCS severity, above and beyond demographic variables and psychological distress. Individuals with a history of mTBI (n = 158) completed surveys online. Sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI) and PCS with the Neurobehavioral Symptom Inventory (NSI). Demographic information was collected and psychological distress was measured using the Brief Symptom Inventory-18 (BSI-18). In this sample, 92% of patients with mTBI reported poor sleep. Sleep quality significantly accounted for the variance in PCS, above and beyond demographics, time since injury and psychological distress (p < 0.001), although only a small amount of the variance in PCS was explained. Results indicate that poor subjective sleep quality is a significant problem in those with mTBI. While sleep is associated with PCS severity, psychological distress is a more potent predictor.
