Abstract Neurofibromatosis Type 1 (NF1) is a rare cause of ischemic stroke (IS) in the general population. We report a case of a young patient with NF1 in whom IS was caused by fibromuscular dysplasia. An angiographic study demonstrated occlusion in the right internal carotid artery (ICA), just after its origin, and the left ICA, just before the intracranial portion, and brain magnetic resonance imaging showed the limits of an area of brain infarction in the right frontoparietal region. Despite these concomitant neuroimaging findings, this association is rare, and it is difficult to establish the contribution to the outcome made by each of these diseases, which treatment is the best to implement, or what prognosis is.

Resumo A neurofibromatose tipo 1 (NF1) é uma causa rara de acidente vascular cerebral isquêmico (AVCi) na população geral. Neste estudo, relatamos o caso de um paciente jovem com AVCi, com diagnóstico de NF1 associada a displasia fibromuscular. O estudo angiográfico demonstrou oclusão da carótida interna direita, logo após sua origem, e esquerda, antes da porção intracraniana. A ressonância magnética do encéfalo mostrou delimitação de um infarto na região frontoparietal direita. Apesar desses achados concomitantes na neuroimagem, essa associação é rara, sendo difícil de estabelecer a contribuição de cada uma dessas doenças no desfecho, tampouco qual o melhor tratamento a ser implementado e qual o prognóstico.

RESUMO A avaliação da velocidade de processamento cognitivo por meio do tempo de reação de escolha (TRE) pode ser uma ferramenta objetiva para acompanhar as alterações cognitivas após a COVID-19. Objetivo: Avaliar o TRE em pacientes após infecção aguda por COVID-19 ao longo de um ano. Métodos: Foram avaliados 30 indivíduos (sexo masculino: nove; feminino: 21) com estado funcional leve-moderado após infecção por COVID-19 e 30 (sexo masculino: oito; feminino: 22) sem COVID-19. A avaliação foi feita pelo Montreal Cognitive Assessment (MoCA) e pela Escala Hospitalar de Ansiedade e Depressão. O TRE (milissegundos) foi avaliado pela diferença entre o sinal luminoso e a latência de início da atividade muscular (EMG) do deltoide anterior (DA), do bíceps braquial (BB) e do tríceps durante uma tarefa de alcance. O TRE foi avaliado ao longo de um ano: avaliação inicial (>4 semanas após diagnóstico de COVID-19), em 3–6 meses e em 6–12 meses. Resultados: Houve redução do TRE do DA no grupo COVID-19 em 3–6 meses (p=0,001) e 6–12 meses (p<0,001) em comparação com o grupo de controle. Também foi observada redução na TRE do tríceps em 6–12 meses (p=0,002) e do BB em 0–3 meses (p<0,001), 3–6 meses (p<0,001) e 6–12 meses (p<0,001) no grupo COVID-19 em comparação com o grupo de controle. Correlações moderadas foram observadas entre MoCA e TRE do DA (r=-0,63; p=0,002) e BB (r=-0,67; p=0,001) aos 6–12 meses no grupo COVID-19. Conclusões: Houve redução do TRE após COVID-19 ao longo de um ano, além de correlação negativa entre MoCA e TRE no período de seis a 12 meses após COVID-19.

ABSTRACT Assessment of cognitive processing speed through choice reaction time (CRT) can be an objective tool to assess cognitive functions after COVID-19 infection. Objective: This study aimed to assess CRT in individuals after acute COVID-19 infection over 1 year. Methods: We prospectively analyzed 30 individuals (male: 9, female: 21) with mild-moderate functional status after COVID-19 and 30 individuals (male: 8, female: 22) without COVID-19. Cognitive and neuropsychiatric symptoms were evaluated using the Montreal Cognitive Assessment (MoCA) and Hospital Anxiety and Depression Scale (HADS), respectively. CRT (milliseconds) was evaluated by finding the difference between the photodiode signal and the electromyographic (EMG) onset latency of anterior deltoid, brachial biceps, and triceps during the task of reaching a luminous target. CRT was evaluated three times over 1 year after COVID-19: baseline assessment (>4 weeks of COVID-19 diagnosis), between 3 and 6 months, and between 6 and 12 months. Results: The multiple comparison analysis shows CRT reduction of the anterior deltoid in the COVID-19 group at 3-6 (p=0.001) and 6-12 months (p<0.001) compared to the control group. We also observed CRT reduction of the triceps at 6-12 months (p=0.002) and brachial biceps at 0-3 (p<0.001), 3-6 (p<0.001), and 6-12 months (p<0.001) in the COVID-19 compared to the control group. Moderate correlations were observed between MoCA and CRT of the anterior deltoid (r=-0.63; p=0.002) and brachial biceps (r=-0.67; p=0.001) at 6–12 months in the COVID-19 group. Conclusions: There was a reduction in CRT after acute COVID-19 over 1 year. A negative correlation was also observed between MoCA and CRT only from 6 to 12 months after COVID-19 infection.

RESUMO As Diretrizes Brasileiras para Reabilitação do AVC são fruto de um esforço conjunto do Departamento Científico de Reabilitação Neurológica da Academia Brasileira de Neurologia com o objetivo de orientar os profissionais envolvidos no processo de reabilitação para a redução da incapacidade funcional e aumento da autonomia dos indivíduos. Membros do grupo acima participaram de fóruns de discussão na web com pré-temas, seguidos de reuniões por videoconferência em que as controvérsias foram discutidas, levando a um consenso. Essas diretrizes, divididas em duas partes, focam as implicações de recentes ensaios clínicos, revisões sistemáticas e metanálises sobre reabilitação do AVC. O objetivo principal é servir de orientação a médicos, fisioterapeutas, fonoaudiólogos, terapeutas ocupacionais, enfermeiros, nutricionistas e demais profissionais envolvidos no cuidado pós-AVC. As recomendações e níveis de evidência foram adaptados de acordo com a literatura disponível atualmente. Aqui é apresentada a Parte I sobre tópicos de reabilitação na fase aguda, prevenção e tratamento de doenças e comorbidades frequentes após o AVC.

ABSTRACT The Guidelines for Stroke Rehabilitation are the result of a joint effort by the Scientific Department of Neurological Rehabilitation of the Brazilian Academy of Neurology aiming to guide professionals involved in the rehabilitation process to reduce functional disability and increase individual autonomy. Members of the group participated in web discussion forums with predefined themes, followed by videoconference meetings in which issues were discussed, leading to a consensus. These guidelines, divided into two parts, focus on the implications of recent clinical trials, systematic reviews, and meta-analyses in stroke rehabilitation literature. The main objective was to guide physicians, physiotherapists, speech therapists, occupational therapists, nurses, nutritionists, and other professionals involved in post-stroke care. Recommendations and levels of evidence were adapted according to the currently available literature. Part I discusses topics on rehabilitation in the acute phase, as well as prevention and management of frequent conditions and comorbidities after stroke.

RESUMO Antecedentes: O acidente vascular cerebral (AVC) é uma das principais causas de morte e sequelas neurológicas no mundo. Muitas escalas auxiliam os profissionais no reconhecimento precoce da doença. Entretanto, nenhum desses instrumentos foi desenvolvido no Brasil. Objetivos: Traduzir a escala Los Angeles Prehospital Stroke Screen (LAPSS) para o português brasileiro, adaptar transculturalmente e validá-la na população brasileira. Métodos: Este estudo ocorreu em duas fases sendo a primeira constituída no processo de validação e adaptação transcultural da LAPSS e a segunda num estudo transversal de dados coletados prospectivamente em pacientes com suspeita de AVC tratados em um pré-hospitalar brasileiro e encaminhados a um centro de AVC. Utilizou-se análise estatística para avaliar a sensibilidade, especificidade e precisão da escala. O coeficiente Kappa de Cohen (κ) foi usado para avaliação psicométrica. Resultados: Após a tradução e adaptação transcultural, a escala foi aplicada em 86 pacientes. O instrumento final apresentou sensibilidade de 83,8%, valor preditivo positivo de 79,60%, especificidade de 40,70%, valor preditivo negativo de 47,80% e acurácia de 77%. O coeficiente Kappa de Cohen foi calculado com os dados de 26 pacientes (30,23%), demonstrando excelente confiabilidade interobservador em 52,96% dos itens da escala. Conclusões: A escala foi traduzida e adaptada transculturalmente para uso no Brasil apresentando alta sensibilidade e acurácia porém baixa especificidade. O coeficiente de Kappa demostrou confiança interobservador. A maior dificuldade ocorreu quando a avaliação física do paciente incluiu identificações subjetivas. Além disso, a escala exclui pacientes com idade menor do que 45 anos como suspeitos de AVC.

ABSTRACT Background: Stroke is one of the leading causes of death and neurological disability in the world. Several scales help professionals in the early recognition of the disease. However, none of these were developed in Brazil. Objectives: To translate the Los Angeles Prehospital Stroke Screen (LAPSS) into Brazilian Portuguese, and cross-culturally adapt and validate the scale in a representative sample of the Brazilian population. Methods: This study was carried out in two phases: the first consisted in the translation and cross-cultural validation of the LAPSS, and the second in a cross-sectional study with prospectively collected data in patients with suspected stroke treated in a Brazilian prehospital and referred to a stroke center. Statistical analysis was used to assess the sensitivity, specificity, and accuracy of the scale. Cohen's Kappa coefficient (κ) was used for psychometric assessment. Results: After translation and cross-cultural adaptation, the scale was applied to 86 patients. The scale presented a sensitivity of 83.8%, positive predictive value of 79.50%, specificity of 40.70%, negative predictive value of 47.80%, and accuracy of 77%. Cohen’s kappa coefficient was calculated using data from 26 (30.23%) patients and the results showed excellent inter-rater reliability in the majority of the items (52.96%). Conclusions: The scale was translated and cross-culturally adapted for use in Brazil. The scale presented high sensitivity and accuracy but low specificity, and the Cohen’s kappa demonstrated inter-rater reliability. The greatest difficulties occurred when the evaluation included subjective identifications. The scale excluded patients < 45 years old as stroke suspects.

RESUMO Antecedentes: Há alta demanda de dados de pacientes com acidente vascular cerebral (AVC) nos sistemas de saúde de países de baixa e média renda. Objetivo: Desenvolver um banco de dados de AVC para integrar dados clínicos ou funcionais e indicadores de qualidade de pacientes com AVC. Métodos: Estudo observacional, transversal e prospectivo. Foi desenvolvida uma ferramenta para coletar dados clínicos durante as internações por AVC por meio de um editor eletrônico de formulários estruturados integrado ao prontuário eletrônico. A validação dos campos no editor eletrônico foi programada em linguagem de consulta estruturada (SQL). Para armazenar os resultados da SQL, uma tabela virtual foi criada e programada para atualização diária. Para desenvolver interface entre os dados e o usuário, foram utilizados o software Embarcadero Delphi e o componente DevExpress para gerar informações apresentadas na tela. Os dados foram extraídos dos campos do formulário e também do cruzamento de outras informações do sistema informatizado, incluindo pacientes internados na unidade de AVC. Resultados: O banco de dados foi criado e integrado ao sistema eletrônico do hospital, permitindo coleta diária de dados. Indicadores de qualidade foram criados no banco de dados para que o sistema acompanhasse e realizasse a tomada de decisão com os gestores dos serviços de saúde, resultando em melhoria no processo e no atendimento ao paciente após AVC. Foi criado um portal inteligente, no qual eram registradas as informações referentes aos pacientes. Conclusões: Com a coleta de dados semiautomática, foi possível criar um banco de dados de AVC dinâmico e otimizado em unidade de AVC no Brasil.

ABSTRACT Background: There is a high demand for stroke patient data in the public health systems of middle and low-income countries. Objective: To develop a stroke databank for integrating clinical or functional data and benchmarks from stroke patients. Methods: This was an observational, cross-sectional, prospective study. A tool was developed to collect all clinical data during hospitalizations due to stroke, using an electronic editor of structured forms that was integrated with electronic medical records. Validation of fields in the electronic editor was programmed using a structured query language (SQL). To store the results from SQL, a virtual table was created and programmed to update daily. To develop an interface between the data and user, the Embarcadero Delphi software and the DevExpress component were used to generate the information displayed on the screen. The data were extracted from the fields of the form and also from cross-referencing of other information from the computerized system, including patients who were admitted to the stroke unit. Results: The database was created and integrated with the hospital electronic system, thus allowing daily data collection. Quality indicators (benchmarks) were created in the database for the system to track and perform decision-making in conjunction with healthcare service managers, which resulted in improved processes and patient care after a stroke. An intelligent portal was created, in which the information referring to the patients was accessible. Conclusions: Based on semi-automated data collection, it was possible to create a dynamic and optimized Brazilian stroke databank.

Abstract Aim: This study aims to evaluate the additional acute effect of virtual reality (VR) head-mounted displays (HMD) when associated with balance exercises in balance outcomes in non-disabled individuals. Methods: Thirty individuals were randomized into two groups: balance exercise group (GBE; n = 15); and virtual reality + balance exercise group (GVR + BE; n = 15). The individuals were evaluated by static and dynamic balance using the tandem test (TT), single-leg stance (SLS), and Fukuda stepping test (FST). Both groups performed 30 min of balance exercises. The GVR + BE performed 8 additional minutes of virtual reality prior to balance exercises. A roller coaster application was used for the HMD. The Mann-Whitney test was used for intra-group and differences of inter-group analysis, considering a significance level of p < 0.05. Results: In the GBE group analysis, there was observed an increase of time in TT with closed eyes (p = 0.025) and SLS with closed eyes (p = 0.003). In the same way, the GVR + BE group increase TT with closed eyes (p = 0.003) and SLS with closed eyes (p = 0.002) after the intervention. In the intergroup analysis, the increase in the SLS with closed eyes was superior in the GVR + BE group when compared with GBE (p = 0.006; d = 1.67). Conclusion: The use of HMD in combination with balance exercise has an acute effect on increasing static balance in non-disabled individuals.

Resumo Antecedentes: A percepção errônea da verticalidade é relativamente comum em pacientes após Acidente Vascular Cerebral (AVC) e pode ser avaliada pelas: (a) vertical visual subjetiva (SVV), (b) vertical háptica subjetiva (SVH) e (c) vertical postural subjetiva (SPV). Para melhor compreender esses métodos de avaliação, realizamos uma revisão sistemática das características metodológicas de diferentes protocolos para avaliações de SVV, SHV e SVP em indivíduos após AVC. Objetivo: Padronizar as características metodológicas de protocolos de avaliação da verticalidade após AVC. Métodos: Foi realizada busca nas bases de dados PUBMED, Portal Regional da BVS (MEDLINE, LILACS, IBECS, CUBMED, Psychology Index, LIS), CINAHL, SCOPUS, Web of Science, Science Direct, Biblioteca Cochrane e PEDro. Dois revisores avaliaram independentemente o QUADAS (Avaliação da Qualidade dos Estudos de Precisão de Diagnóstico) e extraíram os resultados. Resultados: Foram incluídos 21 estudos: a maioria (80,9%) utilizando a SVV, oito (38,1%) a SPV e quatro (19,0%) a SHV. Observou-se grande variabilidade na avaliação da verticalidade, devido às posições dos pacientes, dispositivos utilizados, número de repetições e ângulo de inclinação para iniciar os testes. Conclusão: Esta revisão sistemática é uma das primeiras a explorar todos os métodos de avaliação da verticalidade após o AVC e fornece informações cruciais sobre como realizar os testes para orientar os futuros pesquisadores e clínicos.

Abstract Background: Verticality misperception is relatively common among patients after stroke, and it may be evaluated in terms of (a) subjective visual vertical (SVV), (b) subjective haptic vertical (SHV) and (c) subjective postural vertical (SPV). To better understand these assessment methods, we conducted a systematic review of the methodological characteristics of different protocols for evaluating SVV, SHV and SPV among individuals after stroke. Objective: To standardize the methodological characteristics of protocols for evaluating verticality perception after stroke. Methods: We searched the following databases: PUBMED, regional BVS portal (MEDLINE, LILACS, IBECS, CUBMED, Psychology Index and LIS), CINAHL, SCOPUS, Web of Science, Science Direct, Cochrane Library and PEDro. Two review authors independently used the QUADAS method (Quality Assessment of Diagnostic Accuracy Studies) and extracted data. Results: We included 21 studies in the review: most (80.9%) used SVV, eight (38.1%) used SPV and four (19.0%) used SHV. We observed high variability in assessments of verticality perception, due to patient positions, devices used, numbers of repetitions and angle of inclination for starting the tests. Conclusion: This systematic review was one of the first to explore all the methods of assessing verticality perception after stroke, and it provides crucial information on how to perform the tests, in order to guide future researchers/clinicians.

RESUMO Antecedentes: O sistema nervoso autônomo pode ser modulado pelo exercício físico após o acidente vascular cerebral (AVC), mas faltam evidências que demonstrem que a reabilitação pode ser eficaz no aumento da variabilidade da frequência cardíaca (VFC). Objetivo: Investigar a eficácia e segurança dos programas de reabilitação na modulação da VFC após o AVC. Métodos: A estratégia de busca foi baseada na estratégia PICOT (pacientes: AVC; intervenções: reabilitação; comparações: qualquer grupo de controle; desfechos: VFC; tempo: fase aguda, subaguda e crônica). Foi realizada busca nas bases MEDLINE, CENTRAL, CINAHL, LILACS e SCIELO sem restrições de idioma, sendo incluídos ensaios clínicos randomizados (ECRs), ensaios clínicos quasi-randomizados (quasi-ECRs) e ensaios clínicos não-randomizados (não-ECRs). Dois autores avaliaram independentemente o risco de viés e a metodologia GRADE para classificar a certeza das evidências para cada estudo incluído. Resultados: Quatro estudos (dois ECRs com baixa certeza de evidência e dois não-ECRs com muito baixa certeza de evidência) foram incluídos. Três deles apresentaram modulação autonômica cardíaca durante e após a reabilitação: a razão LF/HF (low frequency/high frequency) foi maior durante a mobilização precoce; maior equilíbrio autonômico foi observado após prática de interação corpo-mente após AVC; e SDNN (desvio padrão dos intervalos R-R normais) foi significativamente menor em pacientes com AVC indicando menor adaptação autonômica cardíaca durante diferentes atividades. Conclusões: Não há conclusão definitivas sobre as principais repercussões cardíaca autonômica nos pacientes com AVC na reabilitação, embora todas as intervenções foram seguras para os pacientes após AVC.

ABSTRACT Background: It has been shown that the autonomic nervous system can be modulated by physical exercise after stroke, but there is a lack of evidence showing rehabilitation can be effective in increasing heart rate variability (HRV). Objective: To investigate the effectiveness and safety of rehabilitation programs in modulating HRV after stroke. Methods: The search strategy was based in the PICOT (patients: stroke; interventions: rehabilitation; comparisons: any control group; outcomes: HRV; time: acute, subacute and chronic phases of stroke). We searched MEDLINE, CENTRAL, CINAHL, LILACS, and SCIELO databases without language restrictions, and included randomized controlled trials (RCTs), quasi-randomized controlled trials (quasi-RCTs), and non-randomized controlled trials (non-RCTs). Two authors independently assessed the risk of bias and we used the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology to rate the certainty of the evidence for each included study. Results: Four studies (two RCTs with low certainty of the evidence and two non-RCTs with very low certainty of the evidence) were included. Three of them showed significant cardiac autonomic modulation during and after stroke rehabilitation: LF/HF ratio (low frequency/high frequency) is higher during early mobilization; better cardiac autonomic balance was observed after body-mind interaction in stroke patients; and resting SDNN (standard deviation of normal R-R intervals) was significantly lower among stroke patients indicating less adaptive cardiac autonomic control during different activities. Conclusions: There are no definitive conclusions about the main cardiac autonomic repercussions observed in post-stroke patients undergoing rehabilitation, although all interventions are safe for patients after stroke.

RESUMO Introdução: O uso de instrumentos padronizados internacionalmente para auxiliar os profissionais de saúde a reconhecer precocemente o AVC é recomendado. O processo de tradução e adaptação transcultural tem sido importante para garantir que a escala seja interpretada da mesma maneira em diferentes idiomas, assegurando sua aplicabilidade em vários países. Objetivo: Traduzir para o idioma português do Brasil, adaptar transculturalmente e validar a Cincinnati Prehospital Stroke Scale na população brasileira. Método: O estudo incluiu pacientes com suspeita de acidente vascular cerebral (AVC) atendidos por um Serviço de Atendimento Móvel Urgência (SAMU) 192 e encaminhados para uma Unidade de Cuidado Integral ao AVC. Foram realizados um processo sistemático de tradução e adaptação transcultural da escala original e a aplicação do instrumento final, que possibilitou a realização dos testes de sensibilidade, especificidade e acurácia, de acordo com o estudo original, além do índice de Cohen de Kappa, para avaliar a confiabilidade interobservador. Resultados: Após a tradução e a adaptação transcultural, a escala foi aplicada em 64 pacientes, apresentando acurácia de 93,0% e sensibilidade de 92,4% em relação ao diagnóstico final, considerado padrão-ouro. Em 26 pacientes (40,6%) foi possível calcular o índice de Cohen de Kappa, evidenciando excelente confiabilidade interobservador entre os itens da escala (0,8385 a 1,0000). Conclusão: A escala apresenta ótima acurácia, sensibilidade e concordância interobservador. Trata-se de um instrumento útil para auxiliar os profissionais da saúde durante a avaliação inicial do paciente com suspeita de AVC, uma vez que contribui significativamente para o reconhecimento precoce da doença de uma maneira simples e rápida.

ABSTRACT Background: Use of internationally standardized instruments to assist healthcare professionals in accurately recognizing stroke early is recommended. The process of translation and cross-cultural adaptation is important for ensuring that scales are interpreted in the same way in different languages, thus ensuring applicability in several countries. Objective: To translate into Brazilian Portuguese, cross-culturally adapt and validate the Cincinnati Prehospital Stroke Scale, using a representative sample of the Brazilian population. Method: The present study included patients with suspected stroke who were treated at a Brazilian emergency medical service and referred to a stroke center. A systematic process of translation and cross-cultural adaptation of the original scale and application of the final instrument was performed. Statistical analysis was used to assess the sensitivity, specificity and accuracy of the scale. Cohen’s kappa coefficient was used to assess inter-rater reliability. Results: After translation and cross-cultural adaptation, the scale was applied to 64 patients. It showed 93.0% accuracy and 92.4% sensitivity in relation to the final “gold standard” diagnosis. Cohen’s kappa coefficient was calculated using data from 26 patients (40.6%) and showed excellent inter-rater reliability between items on the scale (0.8385 to 1.0000). Conclusion: The scale demonstrated excellent accuracy, sensitivity and inter-rater reliability. It was a useful tool for assisting healthcare professionals during initial assessments on patients with suspected stroke and significantly contributed to early recognition of stroke in a simple and quick manner.

ABSTRACT Purpose: this study aimed to verify the occurrence of abnormal vectoelectronystagmography findings in patients with temporomandibular disorders (TMDs). Methods: in this cross-sectional study, patients diagnosed with TMDs underwent an otorhinolaryngological examination, audiological evaluation, and balance and vestibular function examinations, using vectoelectronystagmography. The tests performed were 1) spontaneous nystagmus, 2) saccadic movements, 3) pendular tracking, 4) optokinetic nystagmus gain and velocity, 5) rotational chair testing, and 6) post-caloric vertigo and the direction and velocity of the slow component of nystagmus. Results: thirty patients were selected (22 females and 8 males) with mean age of 30.8(14.9 years. Sensorineural hearing loss was seen in four patients (13.3%); the other patients (86.7%) had results within the normal range at all frequencies. Five patients (16.7%) showed abnormalities on the Romberg test and seven (23.3%) on the Tandem test. Abnormalities on the caloric test were seen in 40.0% of patients. More prevalence of headache (p<0.0001) and tinnitus (p<0.0001) was observed in patients with unilateral hyperreflexia, and dizziness, depression, anxiety, gait imbalance and falls in patients with bilateral hyperreflexia. Conclusion: patients with TMDs may present vectoelectronystagmography abnormalities characterized by unilateral or bilateral hyperreflexia and unilateral hyporeflexia of post-caloric nystagmus.

Abstract Aim: Learning by action observation (AO) is a fundamental cognitive ability existing from birth either in live or in the video. However, the specific AO training, in live or in the video, can influence decision making and motor planning in healthy children? This study aimed to evaluate if a single session of both practices (live and video) modifies the choice reaction time during reaching tasks in healthy children. Methods: This is a cross-sectional and randomized study with 22 children aged 6 to 8 years. We measured the choice reaction time (CRT) by electromyography at baseline and after both practices. Data were analyzed using Friedman and posthoc Dunn non-parametric tests for each age group individually as well as all ages combined. Kurtosis analysis was performed to assess data variability. Results: Significant decrease in CRT was observed after action observation in the video in 8-year-olds. Also, we observed choice reaction time variability reduction in 8-year-olds after both practices compared to that at baseline. Conclusion: A decrease in CRT was observed after the single session of action observation in the video in 8-year-olds. Additionally, there was a reduced variability in CRT after performing both practices in the same age group.

Resumo Contexto A neuroimagem é amplamente utilizada para o diagnóstico e tratamento do acidente vascular cerebral (AVC). No entanto, pouco se sabe se a dose de radiação recebida nesses exames está de acordo com as diretrizes internacionais de segurança. Objetivos O objetivo deste estudo foi avaliar a dose de radiação efetiva (DRE) durante a hospitalização por AVC. Métodos Trata-se de estudo transversal com 109 pacientes hospitalizados com diagnóstico de AVC isquêmico. A gravidade do AVC foi avaliada pela National Institutes of Health Stroke Scale, a topografia pela classificação clínica de Bamford e a etiologia pelo Trial of ORG 10172 in Acute Stroke Treatment (TOAST). O índice de dose recebida no exame de tomografia computadorizada (TC) e as estimativas de dose específicas foram usados para calcular a DRE recebida durante a hospitalização. O teste de Mann-Whitney foi utilizado para comparar a DRE recebida por pacientes trombolisados e não trombolisados. Estatísticas não paramétricas foram utilizadas para analisar os dados. Resultados Durante o período do estudo, a DRE foi de 10,9 mSv. O tempo de internação não foi associado à exposição à radiação. Nenhuma diferença foi demonstrada na DRE de acordo com a etiologia e classificação clínica de Bamford. Os pacientes que fizeram perfusão (isolada, associada à TC ou angiotomografia) receberam a maior DRE (46,5 mSv) em comparação aos que não fizeram (10,8 mSv), sendo estatisticamente significativo (p <0,001). Não foram encontradas diferenças na DRE entre pacientes trombolisados e não trombolisados. Não houve correlação entre a DRE durante a hospitalização com a gravidade do AVC. Conclusões De acordo com as atuais diretrizes nacionais, o protocolo de exame de imagens na unidade de AVC é seguro em relação à DRE recebido pelo paciente durante a internação. Não houve diferença na DRE dos pacientes de acordo com o tratamento trombolítico e a gravidade do AVC.

Abstract Background Neuroimaging is widely used for diagnosis and treatment of stroke. However, little is known about whether the radiation doses received by patients comply with international safety guidelines. Objectives The aim of this study was to evaluate the effective radiation dose received while in hospital for stroke and analyze its safety according to current guidelines. Methods This cross-sectional study included 109 patients who were hospitalized and diagnosed with ischemic stroke. The National Institutes of Health Stroke Scale was used to evaluate stroke severity, the Bamford clinical classification was used for topography, and the TOAST classification was used for etiology. The computed tomography dose index and size-specific dose estimates were used to calculate the effective radiation dose (ERD) received while in hospital. A Mann-Whitney test was used to compare the ERD received by thrombolysed and non-thrombolysed patients. Non-parametric statistics were used to analyze the data with a 95% confidence interval. Results During the study period, the median ERD received was 10.9 mSv. Length of stay was not associated with radiation exposure. No differences were demonstrated in ERD according to stroke etiology or Bamford clinical classification. Patients who had CT perfusion (only or in addition to CT or angiotomography) received the highest ERD (46.5 mSv) and the difference compared to those who did not (10.8 mSv) was statistically significant (p<0.001). No differences were found in the ERD between thrombolysed and non-thrombolysed patients. There was no correlation between ERD while in hospital and stroke severity. Conclusions According to the current national guidelines, the protocol for examining images at our stroke unit is safe in terms of the ERD received by the patient while in hospital. There was no difference in the ERD received by patients stratified by thrombolytic treatment or stroke severity.
