Abstract
Cognitive impairments have frequently been reported in individuals with spinal cord injury (SCI) across different domains such as working memory, attention, and executive function. The mechanism of cognitive impairment after SCI is not well understood due to the heterogeneity of SCI sample populations, and may possibly be due to factors such as cardiovascular dysfunction, concomitant traumatic brain injury (TBI), hypoxia, sleep disorders, and body temperature dysregulation. In this study, we implement the Neuropsychiatric Unit Cognitive Assessment Tool (NUCOG) to assess cognitive differences between individuals with SCI and age-matched able-bodied (AB) controls. We then use an N-back working memory task and functional near-infrared spectroscopy (fNIRS) to elucidate the neurovascular correlates of cognitive function in individuals with SCI. We observed significant differences between the SCI and AB groups on measures of executive function on the NUCOG test. On the N-back task, across the three levels of difficulty: 0-back, 2-back, and 3-back, no significant differences were observed between the SCI and AB group; however, both groups performed worse as the level of difficulty increased. Although there were no significant differences in N-back performance scores between the two groups, functional brain hemodynamic activity differences were observed between the SCI and AB groups, with the SCI group exhibiting higher maximum oxygenated hemoglobin concentration in the right inferior parietal lobe. These findings support the use of fNIRS to study cognitive function in individuals with SCI and may provide a useful tool during rehabilitation to obtain quantitative functional brain activity metrics.

Furlan JC. Concomitant traumatic brain injury as a determinant of survival, and neurological and functional outcomes after traumatic spinal cord injury: A retrospective cohort study. PM R 2023. [PMID: 38151464 DOI: 10.1002/pmrj.13123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Revised: 09/22/2023] [Accepted: 11/02/2023] [Indexed: 12/29/2023]
Abstract
BACKGROUND Although concomitant traumatic brain injury (TBI) is not infrequently associated with spinal cord injury (SCI), there is relatively scarce information about the effects of concomitant TBI on outcomes after SCI. OBJECTIVE To assess the impact of concomitant mild-to-moderate TBI on survival, and neurological and functional outcomes within the first year after acute traumatic SCI. DESIGN Retrospective cohort study. SETTING Acute spine trauma centers in the United States. PARTICIPANTS This study includes all individuals who were enrolled into the Third National Spinal Cord Injury Study (NASCIS-3). The study population was classified into SCI + TBI group and SCI-alone group. TBI was defined as a Glasgow Coma Scale score <15 on admission. INTERVENTION Not applicable. MAIN OUTCOME MEASURES Both groups were compared regarding their survival and neurological outcomes (ie, NASCIS motor, sensory and pain scores) and functional outcome (ie, Functional Independence Measure score) within the first year following SCI. Data analyses were adjusted for major potential confounders. RESULTS There were 413 individuals in the SCI-alone group and 86 individuals in the SCI + TBI group (17.2%). Both groups were comparable regarding gender distribution (p = .621). However, the SCI + TBI group was older (p < .001), had a higher proportion of complete (p = .006) and cervical SCI (p = .003), and had a higher blood alcohol level (p < .001) than the SCI-alone group. The SCI + TBI group did not significantly differ from the SCI-alone group regarding survival within the first year after SCI (p = .768). Among the survivors, concomitant mild-to-moderate TBI did not significantly affect neurological and functional outcomes at 1 year after SCI in the multiple regression analyses after adjusting for major potential confounders. CONCLUSIONS The results of this study suggest that concomitant mild-to-moderate TBI did not have a significant impact on survival, neurological recovery, and functional outcomes at 1 year after SCI, even though there were some epidemiological differences between SCI-alone and SCI + TBI groups.

The incidence and impact of 'Tandem Neurotrauma'. BRAIN & SPINE 2023; 3:102702. [PMID: 38021005 PMCID: PMC10668105 DOI: 10.1016/j.bas.2023.102702] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/31/2023] [Revised: 09/14/2023] [Accepted: 10/20/2023] [Indexed: 12/01/2023]
Abstract
Introduction The epidemiology and prognosis of the isolated traumatic brain injury (TBI) and spinal cord injury (SCI) are well studied. However, the knowledge of the impact of concurrent neurotrauma is very limited. Research questions To characterize the longitudinal incidence of concurrent TBI and SCI and to investigate their combined impact on clinical care and outcomes, compared to a comparative but isolated SCI or TBI. Materials and methods Data from 167,793 patients in the Trauma Audit and Research Network (TARN) registry collected in England and Wales between 2008 and 2018 were analysed. Tandem neurotrauma was defined as patients with concurrent TBI and SCI. The patient with isolated TBI or SCI was matched to the patient with tandem neurotrauma using propensity scores. Results The incidence of tandem neurotrauma increased tenfold between 2008 and 2018, from 0.21 to 2.21 per 100,000 person-years. Patients in the tandem neurotrauma group were more likely to require multiple surgeries, ICU admission, longer ICU and hospital LOS, higher 30-day mortality, and were more likely to be transferred to acute hospitals and rehabilitation or suffer death at discharge, compared to patients with isolated TBI. Likewise, individuals with tandem neurotrauma compared to those with isolated SCI had a higher tendency to receive more than one surgery, ICU admission, longer LOS for ICU and higher mortality either at 30-day follow-up or at discharge. Discussion and conclusions The incidence of tandem neurotrauma has increased steadily during the past decade. Its occurrence leads to greater mortality and care requirements, particularly when compared to TBI alone. Further investigations are warranted to improve outcomes in tandem neurotrauma.

Abstract
PURPOSE OF REVIEW Trauma affecting the nervous system can have widespread consequences, depending on the location and severity of injury. The sensorimotor and cognitive deficits due to neurotrauma have been studied extensively. Although the overall mortality due to neurotrauma has reduced, the disability and morbidity due to neurotrauma has not significantly reduced and focus on urogenital disturbances in these patients has been limited. This article reviews the limited evidence and scientific literature on this topic. RECENT FINDINGS Lower urinary tract symptoms are commonly reported in patients with neurotrauma, both acutely and over the long term. Multiple medical and surgical approaches are available for managing bladder dysfunction in these patients. Sexual dysfunction and changes in sexual behaviour are reported by patients with neurotrauma and are usually multifactorial. Treatment options for sexual dysfunction are available and their management requires a holistic approach. SUMMARY Urogenital dysfunction contributes significantly to the overall functional outcome and impaired quality of life in patients with neurotrauma. A better understanding of the mechanisms behind the urogenital abnormalities is needed for efficient management and treatment.

Abstract
Spinal cord injury (SCI) is a catastrophic event with multiple comorbidities including spastic paralysis, sensory loss, autonomic dysfunction with sympathetic blunting, neurogenic orthostatic hypotension, neurogenic restrictive and obstructive lung disease, neuropathic pain, spasticity, neurogenic bladder, neurogenic bowel, immobilization hypercalcemia, osteopenia/osteoporosis, neurogenic obesity, and metabolic dysfunction. Cervical and thoracic SCI is all too often accompanied by traumatic brain injury (TBI), which carries its own set of comorbidities including headaches, seizures, paroxysmal sympathetic hyperactivity, aphasia, dysphagia, cognitive dysfunction, memory loss, agitation/anxiety, spasticity, bladder and bowel incontinence, and heterotopic ossification. This manuscript will review the etiology and epidemiology of dual diagnoses, assessment of both entities, and discuss some of the most common comorbidities and management strategies to optimize functional recovery.

Abstract
OBJECTIVE Cervical spine injury screening is common practice for traumatic brain injury (TBI) patients. However, risk factors for concomitant thoracolumbar trauma remain unknown. We characterized epidemiology and clinical risk for concomitant thoracolumbar trauma in TBI. METHODS We conducted a multi-center, retrospective cohort analysis of TBI patients in the National Trauma Data Bank from 2011-2014 using multivariable logistic regression. RESULTS Out of 768,718 TBIs, 46,654 (6.1%) and 42,810 (5.6%) patients were diagnosed with thoracic and lumbar spine fractures, respectively. Only 11% of thoracic and 7% of lumbar spine fracture patients had an accompanying spinal cord injury at any level. The most common mechanism of injury was motor vehicle accident (67% of thoracic and 71% and lumbar fractures). Predictors for both thoracic and lumbar fractures included moderate (thoracic: OR 1.26, 95%CI 1.21-1.31; lumbar: OR 1.13, 95%CI 1.08-1.18) and severe Glasgow Coma Scale (GCS) score (OR 1.71, 95%CI 1.67-1.75; OR 1.17, 95%CI 1.13-1.20) compared to mild; epidural hematoma (OR 1.36, 95%CI 1.28-1.44; OR 1.1, 95%CI 1.04-1.19); lower extremity injury (OR 1.38, 95%CI 1.35-1.41; OR 2.50, 95%CI 2.45-2.55); upper extremity injury (OR 2.19, 95%CI 2.14-2.23; OR 1.15, 95%CI 1.13-1.18); smoking (OR 1.09, 95%CI 1.06-1.12; OR 1.12, 95%CI 1.09-1.15); and obesity (OR 1.39, 95%CI 1.34-1.45; OR 1.29, 95%CI 1.24-1.35). Thoracic injuries (OR 4.45; 95% CI 4.35-4.55) predicted lumbar fractures, while abdominal injuries (OR 2.02; 95% CI 1.97-2.07) predicted thoracic fractures. CONCLUSIONS We identified GCS, smoking, upper and lower extremity injuries, and obesity as common risk factors for thoracic and lumbar spinal fractures in TBI.

Abstract
PURPOSE To help individuals make informed choices regarding the optimal type and timing of restorative surgical treatment for cervical spinal cord injury (SCI), more precise information is needed on their ability to perform activities of daily living. The goal of this work was to describe functional independence achieved by individuals with differing levels of cervical SCI. METHODS Using the comprehensive European Multicenter Study of Spinal Cord Injury dataset, analysis was undertaken of individuals with traumatic SCI, motor-level C5-C8. Data on feeding, bladder management, and transfers (bed to wheelchair) were compared between individuals with different levels of injury. Subgroup analyses of symmetrical and asymmetrical SCI and between complete and incomplete SCI were performed. The impact of age, sex, and time postinjury on functional independence was ascertained. RESULTS Data were available for individuals with symmetrical (n = 204) and asymmetrical (n = 95) patterns of SCI. Independence with feeding, urinary function, and transfer ability was increased in individuals with strong finger flexion. Unexpectedly, the presence of strong elbow extension did not uniformly result in the ability to transfer independently. There was no change in any of the analyzed activities between 6 and 12 months postinjury. CONCLUSIONS People with cervical SCI who gain finger flexion have greater independence with feeding, urinary, and transfer activities. Restoration of finger flexion should be a reconstructive priority for individuals with midcervical-level SCI. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic IV.

Abstract
OBJECTIVE To compare and contrast the contributory effects of traumatic brain injury (TBI) and spinal cord injury (SCI) on sexual function and social relationship opportunities, hypothesizing that patterns of change in sexual function would follow etiology. DESIGN Cross-sectional, case-matched survey of community living individuals with TBI, SCI or both (termed dual diagnosis). PARTICIPANTS Consecutive sample of participants with TBI (n = 25), SCI (n = 24) and dual diagnosis (n = 28), an average 3.6 years post-rehabilitation discharge. METHODS Participants were interviewed using a modified version of the 'Sexuality after Spinal Injury Questionnaire.' RESULTS Almost all respondents (97%) perceived adverse post-injury change in their experience of neurosexual function and/or social relationships. Physiological aspects of sexual function (e.g., erection, orgasm) were most affected by SCI whereas social relationships appeared more affected by TBI. People with dual diagnoses exhibited a combination of features. Participants with SCI (with or without TBI) were significantly more likely to have their concerns about sexual function discussed during rehabilitation than the TBI group. CONCLUSION TBI and SCI produce predictable impacts upon sexual function following injury, the impact of which were less frequently addressed during inpatient rehabilitation for those with TBI.

A prospective cohort study investigating contributors to mild cognitive impairment in adults with spinal cord injury: study protocol. BMC Neurol 2020; 20:341. [PMID: 32917161 PMCID: PMC7484605 DOI: 10.1186/s12883-020-01899-7] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2020] [Accepted: 08/23/2020] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Studies report rates of mild cognitive impairment (MCI) in spinal cord injury (SCI) range between 10 and 60%. This broad estimate of MCI in SCI is most likely a result of: (i) inconsistent operationalization of MCI; (ii) heterogeneity among individuals with SCI; (iii) failure to account for MCI subtypes, thereby adding to the heterogeneity of samples; and, (iv) poor control for traumatic brain injury (TBI) that obscures differentiation of MCI attributable to TBI versus other factors. There is a paucity of longitudinal studies following the course of MCI in SCI, and none that account for multiple predictors of MCI, including interactions among predictors. METHODS An inception cohort longitudinal study will assess approximately 100 individuals aged 17-80 years with acute SCI, with measures taken at three timepoints (baseline, 3 months post-baseline, and 12 months post-injury). Data relevant to medical care received within the first 24-48 h of presentation to the emergency department will be analysed, as will measures of cognition, injury characteristics, medical history, personal factors, psychological status, psychosocial functioning, and quality of life. Latent class mixture modelling will determine trajectories for the primary outcome of interest, cognitive functioning and its subtypes, and secondary outcomes of interest such as depression. Multiple regression analyses will identify predictors of MCI and its subtypes. DISCUSSION The prospective design will reveal change in cognitive functioning across time and unveil different outcome trajectories; thus addressing the lack of knowledge on trajectories of MCI and MCI subtypes in SCI. Through subtyping MCI, we hope to yield groups of cognitively impaired individuals with SCI that are potentially more homogenous and thereby stable and predictable. This is the first study to capture emergency department and acute care diagnostic evidence of mild TBI, which has been poorly controlled in previous studies. Our study will also be the first to distinguish the contribution of TBI from other factors to the development of MCI in individuals with SCI. TRIAL REGISTRATION The study was prospectively registered with the Australian and New Zealand Clinical Trial Registry ( ACTRN12619001702101 ) on 3rd December 2019.

Abstract
OBJECTIVES To examine predictors of profiles of cognitive functioning among individuals receiving acute inpatient spinal cord injury (SCI) rehabilitation, as well as associations between their cognitive functioning and psychological well-being (life satisfaction and depression) 6 months after the baseline assessment. DESIGN Prospective observational study design, with 2 assessments approximately 6 months apart. SETTING A rehabilitation unit at a level 1 trauma hospital during acute SCI hospitalization and outpatient setting after discharge. PARTICIPANTS Individuals (N=89) with SCI. INTERVENTION None. MAIN OUTCOME MEASURES Cognitive functioning (assessed by the Repeatable Battery for the Assessment of Neuropsychological Status), life satisfaction (measured by the Life Satisfaction Index A), and depressive symptoms (measured by the Patient Health Questionnaire-9). RESULTS Latent profile analysis identified 3 classes of individuals with similar patterns of cognitive functioning: class1 (average levels of cognitive performance across all assessed domains; n=48), class 2 (average cognitive performance, except in recall and memory; n=23), and class 3 (low cognitive functioning across multiple domains of cognition; n=18). Fewer years of education, history of smoking, history of substance use other than alcohol, and greater postconcussion symptoms were associated with higher odds of classification in class 3 (P<.05). Six months post baseline, individuals in class 3 reported significantly lower levels of life satisfaction than individuals in class 1 (χ2(1)=5.86; P=.045) and marginally higher depressive symptoms than individuals in class 2 (χ2(1)=5.48; P=.057). CONCLUSIONS: The impact of impaired cognition during acute rehabilitation may persist after discharge and influence the psychological well-being of individuals with SCI. Identifying individuals with cognitive dysfunction and attending to modifiable risk factors and may help ameliorate maladjustment after SCI.

PM R 2020; 13:683-694. [PMID: 32710463 DOI: 10.1002/pmrj.12456] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Revised: 06/04/2020] [Accepted: 07/21/2020] [Indexed: 11/07/2022]
Abstract
INTRODUCTION Evidence of the effect of comorbid spinal cord injury (SCI) on cognitive outcomes in persons undergoing rehabilitation following newly diagnosed traumatic brain injury (TBI) is limited. We conducted a population-based study to investigate this effect. OBJECTIVE To compare cognitive outcomes in patients with TBI with and without a comorbid SCI. SETTING/PARTICIPANTS Adult patients diagnosed with TBI were identified and followed for 1 year through provincial health administrative data; those who entered inpatient rehabilitation were studied. DESIGN A retrospective matched cohort study using the National Rehabilitation Reporting System data of all acute care and freestanding rehabilitation hospitals in Ontario, Canada. MAIN MEASURES The exposure was a comorbid SCI in patients with diagnosed TBI. Exposed patients were matched to unexposed (TBI-only) on sex, age, injury severity, and income, in a ratio of one to two. Gain differences in the cognitive subscale of the Functional Independence Measure were compared between exposed and unexposed patients using multivariable mixed linear model, controlling for comorbidity propensity score, gains in motor function, and rehabilitation care indicators. RESULTS Over the first year post injury, 12 750 (0.84%) of all TBI patients entered inpatient rehabilitation, of whom 1359 (10.66%) had a comorbid SCI. A total of 1195 exposed patients (65.4% male, mean age 50.9 ± 20.6 for male and 61.8 ± 21.8 for female patients) were matched to 2390 unexposed patients. Controlling for confounding, exposed patients had lower cognitive gain (beta -0.43; 95% CI -0.72, -0.15), for both male (beta -0.39; 95% CI -0.75, -0.03) and female (beta -0.51; 95% CI -0.97, -0.05) patients. The adverse effects of comorbid SCI were driven largely by lower gains in problem solving and comprehension. CONCLUSIONS Adult patients with TBI and comorbid SCI showed a lower cognitive domain response to inpatient rehabilitation than patients with TBI alone. Identifying patients at risk for worse cognitive outcomes may facilitate the development of targeted strategies that improve cognitive outcomes.

Abstract
STUDY DESIGN Retrospective cohort study. OBJECTIVE Aim of the study is to evaluate the impact of complications at admission on the functional status of spinal cord lesions patients. SETTING Rehabilitation hospital in Italy. METHODS Two hundred and seven patients with complications (mostly pressure ulcers) at admission to rehabilitation were matched for neurological level of injury and AIS grade with 207 patients without complications. MEASURES International Standards for Neurological Classification of Spinal Cord Injury, Spinal Cord Independence Measure, Rivermead Mobility Index, and Walking Index for Spinal Cord Injury. These measures were recorded at admission to rehabilitation and at discharge. We also recorded length of acute and rehabilitation stay and discharge destination. STATISTICS Student's T test for paired samples, McNemar's chi-square test. RESULTS Patients with complications at admission suffered more often from a traumatic lesions. The functional status at admission and discharge of the patients without complications was significantly better than the functional status of patients with complications (Spinal Cord Independence Measure mean difference between the two groups 5.7 (CI 2.8-8.5) at admission, and 10 (CI 5.3-14.7) at discharge). Length of stay was significantly higher in patients with complications. Patients with complications were more often institutionalized than their counterparts (46/161 vs. 20/187, odds ratio 0.4 (CI 0.2-0.7)). CONCLUSIONS Complications seem to be more frequent in patients with traumatic lesions. The presence of complications has a negative effect on patients' functional status at discharge and length of stay, and it determines a higher risk of being institutionalized.

Abstract
: Individuals with concomitant spinal cord injury and traumatic brain injury have cognitive deficits that may limit the ability to learn novel motor tasks necessary for functional independence. Errorless learning has been shown to improve cognitive task performance in persons with brain injury but little is known about its usefulness for improving novel motor task learning. CASE DESCRIPTION A 44-year-old man with traumatic spinal cord and brain injuries from a motor vehicle accident was admitted to an inpatient rehabilitation hospital. His spinal cord injury was classified as T4 American Spinal Injury Association Impairment Scale (AIS) A, and his cognitive status was level IV on the Ranchos Los Amigos Scale. Initially, the patient required maximal assistance from 2 clinicians to complete a slide board transfer, propelled his wheelchair 25 ft with minimal assistance, and scored 9/56 on the Function in Sitting Test. INTERVENTION The therapist applied traditional motor-learning approaches during the first 37 days of the patient's inpatient rehabilitation facility stay without meaningful gains in functional mobility. A subsequent change to errorless learning was made for the following 32 days until discharge. OUTCOMES After use of errorless learning, the patient performed novel mobility-related tasks of slide board transfers with minimal assistance and wheelchair propulsion without physical assistance up to 150 ft; the Function in Sitting Test score improved to 18/56. His sensorimotor system progressed to an AIS classification of AIS B, while his cognition emerged to a level V on the Ranchos Los Amigos Scale. DISCUSSION Errorless learning may have facilitated acquisition of novel transfer and mobility skills in this individual with dual diagnoses. This approach may have value for patients with neurologic conditions who have both motor and cognitive impairment.Video Abstract available for more insights from the authors (see Video, Supplemental Digital Content 1, http://links.lww.com/JNPT/A201).

Abstract
Despite indications that TBI may be a precursor of cognitive decline and subsequent development of Alzheimer's disease, little is known about the time course of this relationship and the factors involved. This systematic review summarizes the evidence pertinent to this subject matter. All English language studies of longitudinal design, and works cited within them, found in six literature databases, were considered, and their quality assessed. Of 65 articles appraised, 44 studies were selected. Results were organized by timing of assessments, injury severity, and cognitive domains assessed. Differences in the course of cognitive performance were observed across injury severity groups and cognitive domains, with differential proportions of reports of improvement, decline, or no change over time. The evidence for genetic, sex-, age-, and injury-related factors as determinants of cognitive outcome was inconsistent. The non-uniform trajectory of cognitive performance post-TBI supports the notion that this construct is non-homogeneous, and that different factors influence its course. Agreement on a core set of predictors and consideration of psychometric properties of outcome measures is needed.

Abstract
Traumatic brain injury (TBI) is the cause for long-term disability in more than 3 million patients in the US alone, with chronic pain being the most frequently reported complain. To date, predisposing mechanisms for chronic pain in TBI patients are largely unknown. Psychological disorders, including post-traumatic stress disorder, depression and anxiety following TBI are commonly reported comorbidities to post-traumatic pain. Long term consequences can be debilitating and affect quality of life even when the injury is mild. In this review, we present the most commonly reported chronic pain conditions across the spectrum of severity of TBI, mainly focusing on mild TBI. We discuss chronic post- traumatic headaches, widespread pain as well as post-traumatic central pain. We discuss pain in the context of injury severity and military versus civilian populations. We are only starting to understand the biological mechanisms behind post-traumatic pain and associated psychological distress following TBI, with genetic, biochemical and imaging studies pointing to the dopaminergic, neurotrophic factors and the role of Apolipoprotein. Physiological and neurological mechanisms are proposed to partially explain this interaction between post-traumatic pain and psychological distress. Nevertheless, the evidence for the role of structural brain damage remains incomplete and to a large extent debatable, as it is still difficult to establish clear causality between brain trauma and chronic pain. Finally, general aspects of management of chronic pain post-TBI are addressed.

Abstract
Objective To examine the occurrence and severity of co-occurring traumatic brain injury (TBI) in persons with traumatic spinal cord injury (SCI), i.e. dual diagnosis (DD), and to describe differences in functional outcomes between persons with DD and SCI only from an inpatient rehabilitation facility (IRF) perspective. Design Retrospective clinical chart review. Setting Acute Midwest SCI inpatient rehabilitation facility. Participants 256 persons age 18-80 years with acute traumatic SCI (AIS A-E, C1-S3 level of injury) from 2002-2012. Interventions Neuroimaging and electronic medical records were reviewed to identify those with co-occurring TBI. Outcomes were then compared between the SCI only and DD groups. Outcome Measures Length of stay (LOS), discharge location and functional independence measures (FIM) Results Forty-one percent of persons with traumatic SCI experienced co-occurring TBI. Rehabilitation LOS for the DD groups did not differ significantly from the SCI only group. Those with Moderate-Severe DD had significantly lower Total admission FIM (P < 0.001), Cognitive admission and discharge FIM (both P < 0.001) and Motor FIM efficiency scores (P = 0.03) compared to those with SCI only and were significantly less likely to discharge home (P = 0.05). Conclusions Persons admitted to IRFs with Moderate-Severe DD compared to those with SCI only are less efficient in obtaining motor skills and may require ongoing rehabilitation to safely return home. It is therefore imperative to initiate early discharge planning and educate rehabilitation team members and families on the additional time and resources necessary to achieve more successful outcomes in those with Moderate-Severe DD.

Abstract
OBJECTIVE To systematically examine the incidence of cognitive impairment in individuals with spinal cord injury (SCI), as well as identify potential contributing and confounding factors. METHODS Studies quantitatively reporting cognitive ability after spinal cord injury were searched electronically via Medline, CINAHL, Embase, and PsycINFO. Manual screening for references within articles was also performed. A total of 2,481 studies were screened and a total of 70 were included in this review, 21 reporting cognitive function after SCI compared to an able-bodied control group and 49 with no able-bodied controls. Studies were analyzed for the incidence of impairment and the interactions with concomitant traumatic brain injury, psychological or somatic complaints, decentralized cardiovascular control, sleep apnea, neurologic level of injury, and age. RESULTS There is a high volume of evidence reporting substantial cognitive impairment in individuals with SCI. Potential co-contributors include concomitant brain injury, psychological or somatic comorbidities, decentralized cardiovascular control, and sleep apnea. Cognitive functioning was negatively correlated with age. No clear agreement was found for the incidence of cognitive impairment or its association with level of injury. CONCLUSION Current evidence suggests that individuals with SCI should be examined and addressed for cognitive impairment. Future studies aimed at identifying potential secondary causative factors should employ stringent controls for co-occurring brain trauma since it appears to be a major contributor and confounder to impaired cognition.

Abstract
Background Concomitant traumatic brain injury with spinal cord injury is likely to worsen prognosis and increase hospital length of stay. This study assessed the duration of in-patient rehabilitation and outcome in patients with both traumatic brain injury and spinal cord injury. Methods Retrospective study of all patients with concomitant traumatic brain injury and spinal cord injury over a 3-year period who had 5 years of subsequent follow-up at the Midlands Centre for Spinal Injuries. Results Twenty-seven patients had concomitant injuries of which five had severe traumatic brain injury, nine had moderate traumatic brain injury and the remaining thirteen had mild traumatic brain injury with spinal cord injury of grades A–D; commonest mechanisms of injury were motor vehicle collision (55%) and falls (37%). Thirteen (48%) had tetraplegia and 14 (52%) had paraplegia. Mean functional independence measure score at admission was 52.1 and 103.4 at 5 years. Patients with mild traumatic brain injury gained a mean functional independence measure score of 67.1; the moderate and severe traumatic brain injury patients gained mean functional independence measure score of 60.1 and 69.2, respectively. The mean length of stay was 138.3, 139.4 and 153.4 days for mild, moderate and severe traumatic brain injury, respectively. Conclusion Hospital length of stay and patient’s functioning at 5 years were not affected by traumatic brain injury severity in this subgroup; however, functional independence measure on its own may not be very sensitive to cognitive deficits.

Abstract
INTRODUCTION Traumatic brain injury (TBI) is among the most disabling injuries, resulting in a range of cognitive impairments. Traumatic spinal cord injury (SCI) often occurs in conjunction with TBI; the two are best considered together in the context of trauma to the central nervous system (CNS). Despite strong indications of cognitive dysfunction in CNS trauma, little is known about its natural history or relationship with other factors. The current protocol outlines a strategy for a systematic review of the current evidence examining CNS trauma as a prognostic factor of cognitive decline in the adult population. METHODS AND ANALYSIS The review will be conducted and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. All peer-reviewed English language publications with a longitudinal design that focus on cognition in adults (ages 18 and older) with either TBI or SCI, or both from inception to December 2016 found through Medline, Central, Embase, Scopus, PsycINFO, supplemental PubMed and bibliographies of identified articles will be considered eligible. Quality will be evaluated using published guidelines. Results will be grouped by: (1) prognostic factors of cognitive deficits; and (2) development of, or time until development of, cognitive deficit in patients with CNS trauma. Close attention will be paid to the evaluative properties of the measurements used to assess cognition. ETHICS AND DISSEMINATION The authors will publish findings from this review in a peer-reviewed scientific journal(s) and present the results at national and international conferences. This work will advance scientific certainty regarding natural history and prognostic factors of cognitive status in males and females with CNS trauma, informing clinicians, policymakers and future researchers on the topic.

Abstract
The objectives were to test the properties, via a psychometric study, of the Overt Behaviour Scale-Self-Report (OBS-SR), a version of the OBS-Adult Scale developed to provide a client perspective on challenging behaviours after acquired brain injury. Study sample 1 consisted of 37 patients with primary brain tumour (PBT) and a family-member informant. Sample 2 consisted of 34 clients with other acquired brain injury (mixed brain injury, MBI) and a service-provider informant. Participants completed the OBS-SR (at two time points), and the Awareness Questionnaire (AQ) and Mayo Portland Adaptability Inventory-III (MPAI-III) once; informants completed the OBS-Adult and AQ once only. PBT-informant dyads displayed "good" levels of agreement (ICC2,k = .74; OBS-SR global index). Although MBI-informant dyads displayed no agreement (ICC2,k = .22; OBS-SR global index), the sub-group (17/29) rated by clinicians as having moderate to good levels of awareness displayed "fair" agreement (ICC2,k = .58; OBS-SR global index). Convergent/divergent validity was demonstrated by significant correlations between OBS-SR subscales and MPAI-III subscales with behavioural content (coefficients in the range .36 -.61). Scores had good reliability across one week (ICC2,k = .69). The OBS-SR took approximately 15 minutes to complete. It was concluded that the OBS-SR demonstrated acceptable reliability and validity, providing a useful resource in understanding clients' perspectives about their behaviour.

Abstract
OBJECTIVES To determine the diagnostic accuracy of a self-report measure of traumatic brain injury (TBI) in people with spinal cord injury (SCI), and to assess the potential effect of TBI on acute and postacute outcomes. DESIGN Incident TBI as determined by self-report was compared with systematic medical records review by physicians blinded to self-reported TBI. SETTING Inpatient rehabilitation unit. PARTICIPANTS From 155 consecutive admissions, participants (N=105; 73% men; mean age, 45.9y; 73% white; 58% with tetraplegia) who met inclusion criteria and were admitted on the day of injury were recruited and assessed. INTERVENTIONS Not applicable. MAIN OUTCOME MEASURE Step 2 of the Traumatic Brain Injury-4 (TBI-4) interview was used to estimate the presence and severity of TBI. RESULTS Estimated incidence of TBI was 33% by chart review and 60% based on Step 2 of the TBI-4. Ninety-one percent of those with TBI based on chart review sustained mild injuries. At the optimal cutoff of "possible TBI," the TBI-4 had a sensitivity of 83% (95% confidence interval, 66%-93%), a specificity of 51% (95% confidence interval, 39%-64%), and a Youden Index of 0.3 (95% confidence interval, 0.2-0.5). Compared with those without TBI, those with chart review-determined TBI had nonsignificant trends toward a longer acute care length of stay and a higher functional status at rehabilitation discharge, but equivalent 1-year outcomes. CONCLUSIONS Step 2 of theTBI-4 did not meet Youden's criteria (≥0.8) for good diagnostic accuracy in the context of recent SCI. Comorbid TBIs were almost exclusively mild and not associated with poorer outcomes 1 year after SCI.

Abstract
Traumatic spinal cord injury (SCI) may result in tetraplegia (motor and/or sensory nervous system impairment of the arms, trunk and legs) or paraplegia (motor and/or sensory impairment of the trunk and/or legs only). The adverse effects of SCI on health, fitness and functioning are frequently compounded by profoundly sedentary behaviour. People with paraplegia (PP) and tetraplegia (TP) have reduced exercise capacity due to paralysis/paresis and reduced exercising stroke volume. TP often further reduces exercise capacity due to lower maximum heart-rate and respiratory function. There is strong, consistent evidence that exercise can improve cardiorespiratory fitness and muscular strength in people with SCI. There is emerging evidence for a range of other exercise benefits, including reduced risk of cardio-metabolic disease, depression and shoulder pain, as well as improved respiratory function, quality-of-life and functional independence. Exercise recommendations for people with SCI are: ≥30min of moderate aerobic exercise on ≥5d/week or ≥20min of vigorous aerobic ≥3d/week; strength training on ≥2d/week, including scapula stabilisers and posterior shoulder girdle; and ≥2d/week flexibility training, including shoulder internal and external rotators. These recommendations may be aspirational for profoundly inactive clients and stratification into "beginning", "intermediate" and "advanced" will assist application of the recommendations in clinical practice. Flexibility exercise is recommended to preserve upper limb function but may not prevent contracture. For people with TP, Rating of Perceived Exertion may provide a more valid indication of exercise intensity than heart rate. The safety and effectiveness of exercise interventions can be enhanced by initial screening for autonomic dysreflexia, orthostatic hypotension, exercise-induced hypotension, thermoregulatory dysfunction, pressure sores, spasticity and pain.
