The Impact of the COVID-19 Pandemic on Traumatic Brain Injury Management: Lessons Learned Over the First Year.

The COVID-19 pandemic has had widespread consequences on health care systems around the world. It resulted in extensive changes to the referral patterns, management, and rehabilitation of surgical conditions. We aimed to evaluate the effect the COVID-19 pandemic has had on traumatic brain injury (TBI) specifically. We reviewed the literature published on COVID-19 and TBI referrals, management, and rehabilitation. Significant changes were seen in the referral patterns of TBIs worldwide, explained by changes in societal behaviors and changes in the mechanism of injury. Implementation of strict infection control measures and COVID-19 screening was commonplace, with some reporting changes to operating room protocols. TBI was more likely to be conservatively managed. Rehabilitation services were restricted, with a greater shift towards telemedicine to provide rehabilitative therapy remotely.

Prelude to the special issue on novel neurocircuit, cellular and molecular targets for developing functional rehabilitation therapies of neurotrauma.

The poor endogenous recovery capacity and other impediments to reinstating sensorimotor or autonomic function after adult neurotrauma have perplexed modern neuroscientists, bioengineers, and physicians for over a century. However, despite limited improvement in options to mitigate acute pathophysiological sequalae, the past 20 years have witnessed marked progresses in developing efficacious rehabilitation strategies for chronic spinal cord and brain injuries. The achievement is mainly attributable to research advancements in elucidating neuroplastic mechanisms for the potential to enhance clinical prognosis. Innovative cross-disciplinary studies have established novel therapeutic targets, theoretical frameworks, and regiments to attain treatment efficacy. This Special Issue contained eight papers that described experimental and human data along with literature reviews regarding the essential roles of the conventionally undervalued factors in neural repair: systemic inflammation, neural-respiratory inflammasome axis, modulation of glutamatergic and monoaminergic neurotransmission, neurogenesis, nerve transfer, recovery neurobiology components, and the spinal cord learning, respiration and central pattern generator neurocircuits. The focus of this work was on how to induce functional recovery from manipulating these underpinnings through their interactions with secondary injury events, peripheral and supraspinal inputs, neuromusculoskeletal network, and interventions (i.e., activity training, pharmacological adjuncts, electrical stimulation, and multimodal neuromechanical, brain-computer interface [BCI] and robotic assistance [RA] devices). The evidence suggested that if key neurocircuits are therapeutically reactivated, rebuilt, and/or modulated under proper sensory feedback, neurological function (e.g., cognition, respiration, limb movement, locomotion, etc.) will likely be reanimated after neurotrauma. The efficacy can be optimized by individualizing multimodal rehabilitation treatments via BCI/RA-integrated drug administration and neuromechanical protheses.

Automation of training and testing motor and related tasks in pre-clinical behavioural and rehabilitative neuroscience.

Testing and training animals in motor and related tasks is a cornerstone of pre-clinical behavioural and rehabilitative neuroscience. Yet manually testing and training animals in these tasks is time consuming and analyses are often subjective. Consequently, there have been many recent advances in automating both the administration and analyses of animal behavioural training and testing. This review is an in-depth appraisal of the history of, and recent developments in, the automation of animal behavioural assays used in neuroscience. We describe the use of common locomotor and non-locomotor tasks used for motor training and testing before and after nervous system injury. This includes a discussion of how these tasks help us to understand the underlying mechanisms of neurological repair and the utility of some tasks for the delivery of rehabilitative training to enhance recovery. We propose two general approaches to automation: automating the physical administration of behavioural tasks (i.e., devices used to facilitate task training, rehabilitative training, and motor testing) and leveraging the use of machine learning in behaviour analysis to generate large volumes of unbiased and comprehensive data. The advantages and disadvantages of automating various motor tasks as well as the limitations of machine learning analyses are examined. In closing, we provide a critical appraisal of the current state of automation in animal behavioural neuroscience and a prospective on some of the advances in machine learning we believe will dramatically enhance the usefulness of these approaches for behavioural neuroscientists.

Neurorehabilitation in the times of Covid-19: insights from the Spanish Neurorehabilitation Society (SENR).

The entire world is experiencing an unprecedented global health crisis and Spain has been one of the most heavily affected countries within Europe. Unexpected rapid changes and reorganization of medical services that occurred during the pandemic lead to an impact in the practice of neurorehabilitation. The idiosyncrasies typical of neurorehabilitation management, specially in acute facilities, that makes it susceptible as a vector of dissemination of Covid but also because of the need of finding new wards and intensive care units for Covid patients, the interventions in neurorehabilitation has suffered enormous changes. There is a need for rethinking the future to treat a new wave of patients with neurorehabilitation necessities such as those recovering from Covid 19 with neurological sequelae but also of those neurorehab patients who were unable to access the health system during the locke down period. This article is intended to invite to reflect on and discuss the redesign of our current neurorehabilitation plans after the experience on the Covid 19 pandemic.

What can virtual reality offer to stroke patients? A narrative review of the literature.

BACKGROUND: Studies demonstrated the efficacy of virtual reality (VR) as a method supporting the post-stroke neuro-rehabilitation process by activating motor learning processes. Nevertheless, stroke is frequently accompanied by serious psychological problems including depression, which is associated with an increased risk of mortality, lower post-stroke physical activity, and higher disability in stroke patients. OBJECTIVES: To explore the current use of VR as a method supporting the neuro-rehabilitation process, both in physical and psychological dimensions. METHODS: An exploratory review was conducted with a narrative synthesis. PubMed was used for literature search. Search includes the use of VR in physical rehabilitation, and as support therapy in psychiatric disorders. Both primary research and systematic reviews were included. RESULTS: In neurological disorders rehabilitation, out of 22 studies, 16 concerned stroke survivors. In psychiatric disorders, 44 literature reviews were included. CONCLUSION: The studies confirmed the effectiveness of various forms of VR treatment in the alleviation of psychological and behavioral problems and psychiatric disorders. There is a shortage of VR-based technological solutions that would, besides physical rehabilitation, offer stroke patients therapeutic tools to alleviate psychological disturbance and improve the patient's mood and motivation. Such solutions will most likely become a field of intensive research in the coming years.

Adipokines as Potential Biomarkers in the Neurorehabilitation of Obese Stroke Patients.

BACKGROUND: Limited studies concern the influence of obesity-induced dysregulation of adipokines in functional recovery after stroke neurorehabilitation. OBJECTIVE: To investigate the relationship between serum leptin, resistin, and adiponectin and functional recovery before and after neurorehabilitation of obese stroke patients. The adipokine potential significance as prognostic markers of rehabilitation outcomes was also verified. METHODS: Twenty obese post-acute stroke patients before and after neurorehabilitation and thirteen obese volunteers without-stroke, as controls, were examined. Adipokines were determined by commercially available enzyme-linked immunosorbent assay (ELISA) kits. Functional deficits were assessed before and after neurorehabilitation with the Barthel Index (BI), modified Rankin Scale (mRS), and Functional Independence Measure (FIM). RESULTS: Compared to controls, higher leptin and resistin values and lower adiponectin values were observed in stroke patients before neurorehabilitation and no correlations were found between adipokines and clinical outcome measures. Neurorehabilitation was associated with improved scores of BI, mRS, and FIM. After neurorehabilitation, decreased values of Body Mass Index (BMI) and resistin together increased adiponectin were detected in stroke patients, while leptin decreased but not statistically. Comparing adipokine values assessed before neurorehabilitation with the outcome measures after neurorehabilitation, correlations were observed for leptin with BI-score, mRS-score, and FIM-score. No other adipokine levels nor BMI assessed before neurorehabilitation correlated with the clinical measures after neurorehabilitation. The forward stepwise regression analysis identified leptin as prognostic factor for BI, mRS, and FIM. CONCLUSION: Our data show the effectiveness of neurorehabilitation in modulating adipokines levels and suggest that leptin could assume the significance of biomarker of functional recovery.

Spinal cord injury and development of pressure injury during acute rehabilitation in Norway: a national retrospective cross-sectional study.

STUDY DESIGN: A national, retrospective, cross-sectional study. OBJECTIVES: To analyze the prevalence of pressure injury (PI), and characteristics associated with PI development in the hospitalized population of persons with a newly acquired spinal cord injury (SCI) between 2004 and 2014. SETTING: All three specialized Spinal Cord Units in Norway. METHODS: Demographic data related to prevalence and potential risk factors were retrieved from the electronic medical record (EMR). Statistical analyses were performed, using IBM SPSS Statistics, version 23. RESULTS: We identified 1012 individuals with a new SCI. Mean age at injury was 48 years (SD 19). The period prevalence of PI was 16% (95% CI = 0.14-0.19), and identified PI associations were complete SCI (OR = 0.1), being injured abroad (OR = 2.4), bowel (OR = 13), and bladder (OR = 9.2) dysfunction; comorbidities like diabetes mellitus 1 (OR = 7.9), diagnosed depression (OR = 3.8), ventilator support (OR = 3.0), drug abuse (OR = 3.0), and concurrent traumatic brain injury (OR = 1.7). Individuals in the age group of 15-29 years had higher odds of PI compared with middle-aged individuals (45-59 years). CONCLUSION: PI is a serious complication after SCI. The association between depression or comorbidity and PI occurrence should be investigated more thoroughly. We recommend implementation of a simple follow-up program regarding observation and prevention of PI. Increased awareness of factors that could contribute to PI will help to focus on better prevention and early recognition of PI. This will contribute to more optimal rehabilitation.

[Second look: practical diagnostic and therapeutic checks in neurorehabilitation]. / Der zweite Blick: praktische diagnostische und therapeutische Checks in der rehabilitativen Neurologie.

Post-acute inpatient neurorehabilitation facilities are increasingly treating patients who are not only severely ill and multimorbid but who are also referred from non-neurological departments. These patients are still often medically unstable so that the previous diagnostics and treatment must be reevaluated and when necessary adapted or supplemented. Certain interdisciplinary diagnostic and therapeutic problems, such as antithrombotic therapy, regularly reoccur. This article presents these problems in a checklist fashion, which should provide indications in individual cases when previously carried out measures need to be questioned and adapted.

Community reintegration following holistic milieu-oriented neurorehabilitation up to 30 years post-discharge.

BACKGROUND: The primary goal of neurorehabilitation for individuals with acquired brain injury (ABI) is successful community reintegration, which commonly focuses on home independence, productivity, and social engagement. Previous research has demonstrated that holistic treatment approaches have better long-term outcomes than other treatment approaches. Holistic approaches go beyond the fundamental components of neurorehabilitation and address metacognition and self-awareness, as well as interpersonal and functional skills. OBJECTIVES: The present study aimed to examine community reintegration of individuals with ABI who completed holistic milieu-oriented neurorehabilitation at the Center for Transitional Neuro-Rehabilitation (CTN), Barrow Neurological Institute (BNI) at up to 30-years post-discharge. We evaluated (a) functional independence, (b) productivity and driving status, and (c) psychosocial profiles of the brain injury survivors. METHOD: Participants included 107 individuals with ABI with heterogeneous etiologies who attended holistic milieu-oriented neurorehabilitation between 1986 and 2016. These participants completed the Mayo-Portland Adaptability Inventory-4 (MPAI-4) and a long-term outcome questionnaire (LOQ) specifically developed for this study. RESULTS: The results demonstrate that 89% of participants were productive at up to 30 years post-discharge (73% engaged in competitive work and/or school) after excluding the retired participants. Almost all of the participants who were engaged in work and/or school reported using compensatory strategies on a long-term basis. Furthermore, only 14% out of 102 study participants were driving at the time of program admission; whereas 58% out of 96 were driving at the time of discharge; and impressively, 70% out of 107 participants were driving at the time of follow-up. Regression analyses revealed that older age at the time of injury, shorter duration between injury and treatment, and better functionality indicated by lower MPAI-4 Ability Index scores significantly predicted a return to driving status at the time of study participation. Psychosocial data from the LOQ revealed positive findings with respect to patients' marital status, living situation, income, and quality of social life. CONCLUSION: The findings from this study suggest that functional gains made during holistic neurorehabilitation have enduring effects and that patients can benefit highly from holistic milieu therapy beyond the early post-acute phases of their recovery. Additionally, they provide evidence that there is potential to return to driving, years after treatment completion.Our holistic milieu treatment approach addressing metacognition, self-awareness, social and coping skills training, and actively transitioning to community settings, is thought to have contributed to the exceptional and long-lasting outcomes in this study.

JNER at 15 years: analysis of the state of neuroengineering and rehabilitation.

On JNER's 15th anniversary, this editorial analyzes the state of the field of neuroengineering and rehabilitation. I first discuss some ways that the nature of neurorehabilitation research has evolved in the past 15 years based on my perspective as editor-in-chief of JNER and a researcher in the field. I highlight increasing reliance on advanced technologies, improved rigor and openness of research, and three, related, new paradigms - wearable devices, the Cybathlon competition, and human augmentation studies - indicators that neurorehabilitation is squarely in the age of wearability. Then, I briefly speculate on how the field might make progress going forward, highlighting the need for new models of training and learning driven by big data, better personalization and targeting, and an increase in the quantity and quality of usability and uptake studies to improve translation.

Demographical and clinical indices for long-term evolution of patients in vegetative or in minimally conscious state.

Objective. To evaluate the prognostic value of demographical, anamnestic, and clinical findings on long-term outcome (up to 36 months) in individuals with severe brain injury in vegetative state (VS) or in minimally conscious state (MCS).Participants. Patients (N = 216) in VS (N = 159) or in MCS (N = 57) consecutively admitted to a neurorehabilitation unit within 1-3 months after severe anoxic (n = 71), vascular (n = 96), or traumatic (n = 49) brain injury.Main outcome. Mortality and improvements in clinical diagnosis at 12, 24, and 36 months after brain injury. Multivariable logistic regression analyses were performed to verify independent relationships of variables collected at study entry with outcome measures.Results. In patients in VS, at the 12-month follow-up, higher level of responsiveness assessed by the Coma Recovery Scale-Revised (CRS-R) total scores at study entry predicted a higher likelihood of both survival and clinical improvement, whereas younger age predicted survival only. At 24 months, female sex and higher CRS-R total scores tended to be associated with clinical improvements. In patients in MCS, younger age and female predicted consciousness recovery at 12 months.Conclusions. Several patients' features easy to collect in rehabilitation setting might help clinicians in prognostication of long-term mortality and clinical evolution of VS and MCS.

Desarrollo y validación externa de un modelo pronóstico precoz para supervivientes de una parada cardiaca extrahospitalaria / Development and external validation of an early prognostic model for survivors of out-of-hospital cardiac arrest

Introducción y objetivos: A pesar del uso de la hipotermia terapéutica, los pacientes recuperados tras sufrir una parada cardiaca extrahospitalaria tienen un elevado riesgo de muerte o deterioro neurológico grave. Se analizaron la utilidad de diversas variables disponibles al ingreso hospitalario para predecir su evolución a los 6 meses. Métodos: Se desarrolló un estudio multicéntrico en 3 unidades de cuidados intensivos cardiacos. El análisis se realizó sobre 153 pacientes ingresados en dos centros tras sufrir una parada cardiaca extrahospitalaria recuperada y que se trataron con control de temperatura, entre enero de 2007 y julio de 2015. Se consideraron secuelas neurológicas significativas si la Cerebral Performance Categories Scale > 2 a los 6 meses. Los resultados se validaron externamente con los datos procedentes de otros 91 pacientes ingresados en un tercer hospital, durante el mismo periodo de tiempo. Resultados: Del total de 244 pacientes (mediana de edad, 60 años; 77,1% varones; 50,0% en el contexto de isquemia miocárdica aguda), 107 (43,8%) sobrevivieron a los 6 meses con una evolución neurológica favorable. Se calculó un modelo predictivo que incluyó 5 variables (primer ritmo, edad, lactato al ingreso, tiempo hasta recuperación de circulación espontánea y diabetes), con un área bajo la curva de 0,90 (IC95%, 0,85-0,95). Cuando se realizó la validación externa del modelo, la sensibilidad fue de 73,5%, con una especificidad de 78,6% y un área bajo la curva de 0,82 (IC95%, 0,73-0,91). Conclusiones: Un modelo predictivo que incluye cinco variables disponibles en el momento de ingreso de pacientes recuperados tras sufrir una parada cardiaca extrahospitalaria puede ayudar a predecir la probabilidad de supervivencia libre de secuelas neurológicas graves en el seguimiento

Introduction and objectives: Despite therapeutic hypothermia, unconscious survivors of out-of-hospital cardiac arrest have a high risk of death or poor neurologic function. Our objective was to assess the usefulness of the variables obtained in the early moments after resuscitation in the prediction of 6-month prognosis. Methods: A multicenter study was performed in 3 intensive cardiac care units. The analysis was done in 153 consecutive survivors of out-of-hospital cardiac arrest who underwent targeted temperature management between January 2007 and July 2015. Significant neurological sequelae at 6 months were considered to be present in patients with Cerebral Performance Categories Scale > 2. An external validation was performed with data from 91 patients admitted to a third hospital in the same time interval. Results: Among the 244 analyzed patients (median age, 60 years; 77.1% male; 50.0% in the context of acute myocardial ischemia), 107 patients (43.8%) survived with good neurological status at 6 months. The prediction model included 5 variables (Shockable rhythm, Age, Lactate levels, Time Elapsed to return of spontaneous circulation, and Diabetes - SALTED) and provided an area under the curve of 0.90 (95%CI, 0.85-0.95). When external validation was performed, the predictive model showed a sensitivity of 73.5%, specificity of 78.6%, and area under the curve of 0.82 (95%CI, 0.73-0.91). Conclusions: A predictive model that includes 5 clinical and easily accessible variables at admission can help to predict the probability of survival without major neurological damage following out-of-hospital cardiac arrest

Effectiveness of intensive neurorehabilitation in obese subacute stroke patients.

The relationship between abdominal subcutaneous adipose tissue thickness (aSAT), body fat percentage (BFP), waist-to-hip ratio (WHR) and body mass index (BMI) and outcome measures of neurological deficit and functional recovery was evaluated in obese subacute stroke patients before and after neurorehabilitation. Decreased National Institutes of Health Stroke Scale (p = 0.0001) and modified Rankin Scale (mRS) (p= 0.002) scores, as well as increased Barthel Index (p= 0.0001) scores were detected after neurorehabilitation. Decreased BMI, aSAT, BFP and WHR observed after neurorehabilitation did not penalize the overall functional recovery as shown by correlations between the clinical measure scores and fat mass indices. The correlation observed after neurorehabilitation between BMI and mRS (rho = 0.4526, p < 0.05) suggests that a high BMI may compromise functional recovery. Monitoring of body fat mass indices may provide information aimed at improving the disability of obese stroke patients.
