A criança com paralisia cerebral na educação infantil: um olhar sobre a prática docente

La inclusión de los niños con discapacidad en la educación infantil, además de ser un tema poco planteado en la comunidad científica, es un reto actual en lo que se refiere a la práctica docente. Basándose en este aspecto, nuestro objetivo en esta investigación realizada, que resultó en la elaboración de este trabajo, fue analizar cómo se procesa la práctica docente con vistas a la inclusión escolar de un niño con parálisis cerebral, en un Centro Municipal de Educación Infantil (CMEI), en la ciudad de Natal / RN. Más específicamente, buscamos: reflexionar sobre la práctica de la profesora responsable por la clase, en lo que se refiere al desarrollo del niño con parálisis cerebral; analizar las interacciones entre educador y niño con parálisis cerebral; observar la práctica docente en la perspectiva de favorecer la interacción entre el niño con parálisis cerebral y otros niños. Para ello, realizamos una pesquisa exploratoria, cualitativa, y así que optamos por el método del Estudio de Caso. Utilizamos como procedimientos metodológicos el análisis documental, la investigación bibliográfica, la entrevista semiestructurada, la observación y la filmación de escenas relacionadas a la práctica docente. Los sujetos de la investigación fueron la profesora y el niño con parálisis cerebral. Los datos construidos durante la investigación señalaron el hecho de que la práctica de la profesora no estaba encaminada a las necesidades específicas de la alumna con parálisis cerebral, todavía, se desarrollaba de una manera similar para todos los niños en la clase. La presencia de limitaciones significativas para la inclusión de la niña con parálisis cerebral en la educación infantil puede ser considerado como el resultado de la ausencia de una adecuada preparación docente, tanto en el nivel de la formación inicial, cuanto de una formación continua y también la escasez de directrices para el maestro, en proceso; directrices estas acerca de la educación de los niños con parálisis cerebral, lo que hacía imposible a la profesora contribuir de manera efectiva a su mayor desarrollo cognitivo y social.

Efeito agudo da respiração abdominal lenta sobre a atividade cerebral, respostas emocionais e cardiovasculares

Introduction: Slow abdominal breathing (SAB) stimulates baroreflex and generates respiratory sinus arrhythmia, changing cardiovascular, emotional and cerebral systems acute and chronically. However, although meditative practices have been receiving increasingly attention in the last years, there is no agreement on the neurophysiological changes underlying them, mainly because of the lack of topographical pieces of information. Purpose: We aimed to analyze the acute effect of SAB on brain activity, emotional and cardiovascular responses in untrained subjects in meditative techniques. Methods: Seventeen healthy adults’ men were assessed into two different sessions in a random and crossed order. Into experimental session, they breathed in 6 cycles/minute and in control session they kept breathing in normal rate, both for 20 minutes. xi Before, during, and after each session we assessed brain activity using electroencephalography (EEG), anxiety, mood, heart rate variability (HRV) and blood pressure. The sLORETA software was used to analyze EEG data for source localization of brain areas in which activity was changed. Results: The sLORETA showed that beta band frequency was reduced in frontal gyrus (P<0.01) and anterior cingulate cortex (P<0.05) both during and after SAB (P<0.05) compared to the moment before it. There was no change in brain activity in control session. Additionally, a two-way repeated measures ANOVA showed that there was no effect on anxiety (P>0.8) and mood (P>0.08). There were improvements in HRV (P<0.03), with increased RR interval and decreased HR after SAB, as well as increased SDNN, RMSSD, pNN50, low frequency, LF/HF ratio, and total power during it, with no changes in SBP and DBP. Conclusions: We conclude that SAB is able to change brain activity in areas responsible for emotional processing, even without behavioral changes. Furthermore, SAB improves HRV and does not change blood pressure in normotensive.

Atividade eletroencefalográfica de pacientes com acidente vascular cerebral na aprendizagem motora de um jogo baseado em realidade virtual

Stroke is the leading cause of long-term disability among adults and motor relearning is essential in motor sequelae recovery. Therefore, various techniques have been proposed to achieve this end, among them Virtual Reality. The aim of the study was to evaluate electroencephalographic activity of stroke patients in motor learning of a virtual reality-based game. The study included 10 patients with chronic stroke, right-hande; 5 with left brain injury (LP), mean age 48.8 years (± 4.76) and 5 with injury to the right (RP), mean age 52 years (± 10.93). Participants were evaluated for electroencephalographic (EEG) activity and performance while performing 15 repetitions of darts game in XBOX Kinect and also through the NIHSS, MMSE, Fugl-Meyer and the modified Ashworth scale. Patients underwent a trainning with 45 repetitions of virtual darts game, 12 sessions in four weeks. After training, patients underwent reassessment of EEG activity and performance in virtual game of darts (retention). Data were analyzed using ANOVA for repeated measures. According to the results, there were differences between the groups (PD and PE) in frequencies Low Alpha (p = 0.0001), High Alpha (p = 0.0001) and Beta (p = 0.0001). There was an increase in alpha activation powers and a decrease in beta in the phase retention of RP group. In LP group was observed increased alpha activation potency, but without decrease in beta activation. Considering the asymmetry score, RP group increased brain activation in the left hemisphere with the practice in the frontal areas, however, LP group had increased activation of the right hemisphere in fronto-central areas, temporal and parietal. As for performance, it was observed a decrease in absolute error in the game for RP group between assessment and retention (p = 0.015), but this difference was not observed for LP group (p = 0.135). It follows then that the right brain injury patients benefited more from darts game training in the virtual environment with respect to the motor learning process, reducing neural effort in ipsilesionais areas and errors with the practice of the task. In contrast, patients with lesions in left hemisphere decrease neural effort in contralesionais areas important for motor learning and showed no performance improvements with practice of 12 sessions of virtual dart game. Thus, the RV can be used in rehabilitation of stroke patients upper limb, but the laterality of the injury should be considered in programming the motor learning protocol.

Novel Virtual Environment for Alternative Treatment of Children with Cerebral Palsy

Cerebral palsy is a severe condition usually caused by decreased brain oxygenation during pregnancy, at birth or soon after birth. Conventional treatments for cerebral palsy are often tiresome and expensive, leading patients to quit treatment. In this paper, we describe a virtual environment for patients to engage in a playful therapeutic game for neuropsychomotor rehabilitation, based on the experience of the occupational therapy program of the Nucleus for Integrated Medical Assistance (NAMI) at the University of Fortaleza, Brazil. Integration between patient and virtual environment occurs through the hand motion sensor “Leap Motion,” plus the electroencephalographic sensor “MindWave,” responsible for measuring attention levels during task execution. To evaluate the virtual environment, eight clinical experts on cerebral palsy were subjected to a questionnaire regarding the potential of the experimental virtual environment to promote cognitive and motor rehabilitation, as well as the potential of the treatment to enhance risks and/or negatively influence the patient’s development. Based on the very positive appraisal of the experts, we propose that the experimental virtual environment is a promising alternative tool for the rehabilitation of children with cerebral palsy.

Observação da ação na reabilitação do membro superior de pacientes com acidente vascular cerebral: uma revisão sistemática com metanálise

Background: stroke causes long-term impairments, limitation of activities and restriction in participation in daily life situations, especially for upper limb impairment (UL). Action Observation (AO) has been used for the rehabilitation of UL in these patients. It's a multisensory therapy which consists in observing a healthy subject performing a motor task, followed by physical practice. Objectives: assess whether the AO improves motor function of UL and dependence for activities of daily living (ADLs) of stroke patients or cause any adverse effects. Search methods: a search strategy was words and terms used for the identification of articles, in the following scientific basis Cochrane Central Register of Controlled Trials; MEDLINE; PsycINFO; CINAHL and LILACS. In addition to manual search of the references of articles and search for theses and dissertations in Portal Capes and LILACS. The identification of the studies was conducted from October to December 2015, being the last search on December 3. Selection criteria: randomised controlled trials (RCT) involving adults with stroke who had deficits in upper limb function and used AO as an intervention. Data collection and analysis: the data extracted from the studies were used to analyze the risk of bias, the effect of the treatment and the quality of the body of evidence. Main results: 6 studies were included, totaling 270 patients. The primary outcome analyzed was the motor function of MS. Were combined in meta-analyzes studies comparing AO versus placebo or an active control, considering the immediate and long-term effect (n=241). Regarding the motor function of the arm (5 trials), the estimated effect for the therapy was not significant. However, when considering the hand function estimating the effect was favorable to the group that conducted the AO, in short (mean difference = 6.93, 95% CI 1.48 to 12.39; P = 0.01) and long-term (mean difference = 7.57; 95% CI 1.34 the 13.80; p = 0.02). Unable to perform the analysis for functional dependency. The studies showed a low or uncertain risk of bias, but the quality of evidence the body was considered low and very low quality. Authors’ conclusions: AO was effective in improving hand function of stroke patients. Despite the low quality evidence that the use of OA in clinical practice should not be discouraged. RCT new studies should be conducted with greater methodological rigor and larger samples, covering important outcomes such as functional dependence for ADLs.

Efeitos do treino de marcha em esteira com adição de carga ao membro inferior não parético de indivíduos com acidente vascular cerebral: ensaio clínico controlado e randomizado

Introduction: Gait after stroke is characterized by a significant asymmetry between the lower limbs, with predominant use of the non-paretic lower limb (NPLL) over using the paretic lower limb. Accordingly, it has been suggested that adding load/weight to the NPLL as a form of restricting the movement of this limb may favor the use of the paretic limb, reducing interlimb asymmetry. However, few studies have been conducted up to this moment, which only investigated the immediate effects of this practice. Objectives: 1) Investigating whether there is an influence of adding load to the NPLL during treadmill training on cardiovascular parameters and on gait performance of individuals with stroke, compared to treadmill training without load addition; 2) Analyzing the effects of treadmill training with and without load added to the NPLL on kinematic parameters of each lower limb during gait; 3) Analyzing the effects of treadmill training with and without load added to the NPLL on measurements of functional mobility and postural balance of these patients. Materials and Methods: This is a randomized single blinded clinical trial involving 38 subjects, with a mean age of 56.5 years, at the subacute post-stroke phase (with mean time since stroke of 4.5 months). Participants were randomly assigned into an experimental group (EG) or control group (CG). EG (n= 19) was submitted to gait training on a treadmill with the addition of load to the NPLL by ankle weights equivalent to 5% of body weight. CG (n= 19) was only submitted to gait training on a treadmill. Behavioral strategies which included home exercises were also applied to both groups. The interventions occurred daily for two consecutive weeks (Day 1 to Day 9), being of 30 minutes duration each. Outcome measures: postural balance (Berg Functional Balance Scale – BBS), functional mobility (Timed Up and Go – TUG; kinematic variables of 180° turning) and kinematic gait variables were assessed at baseline (Day 0), after four training sessions (Day 4), after nine training sessions (Day 9), and 40 days after completion of training (Follow-up). Cardiovascular parameters (mean arterial pressure and heart rate) were evaluated at four moments within each training session. Analysis of variance (ANOVA) was used to compare outcomes between EG and CG in the course of the study (Day 0, Day 4, Day 9 and Follow-up). Unpaired t-tests allowed for intergroup comparison at each training session. 5% significance was used for all tests. Results: 1) Cardiovascular parameters (systemic arterial pressure, heart rate and derivated variables) did not change after the interventions and there were no differences between groups within each training session. There was an improvement in gait performance, with increased speed and distance covered, with no statistically significant difference between groups. 2) After the interventions, patients had increased paretic and non-paretic step lengths, in addition to exhibiting greater hip and knee joint excursion on both lower limbs. The gains were observed in the EG and CG, with no statistical difference between the groups and (mostly) maintained at follow-up. 3) After the interventions, patients showed better postural balance (higher scores on BBS) and functional mobility (reduced time spent on the TUG test and better performance on the 180° turning). All gains were observed in the EG and CG, with no statistically significant difference between groups and were maintained at follow-up. Conclusions: The addition of load to the NPLL did not affect cardiovascular parameters in patients with subacute stroke, similar to treadmill training without load, thus seemingly a safe training to be applied to these patients. However, the use of the load did not bring any additional benefits to gait training. The gait training program (nine training sessions on a treadmill + strategies and exercises for paretic limb stimulation) was useful for improving gait performance and kinematics, functional mobility and postural balance, and its use is suggested to promote the optimization of these outcomes in the subacute phase after stroke.

Entorno de realidad virtual controlado en tiempo real por señales motoras para la rehabilitación del miembro superior en pacientes con daño cerebral

Este trabajo tiene como meta el desarrollo de un sistema de neurorrehabilitación mediante realidad virtual para pacientes con problemas motores en las extremidades superiores provocados por un daño cerebral. Para entender y enfrentarse de manera correcta al problema, se han revisado todos los aspectos concernientes al daño cerebral y déficits motores derivados así como las terapias empleadas para su rehabilitación, como las que utilizan tecnologías asistidas como la realidad virtual. Se han expuesto las ventajas que han llevado a utilizar esta terapia en el proyecto y se han mencionado algunos estudios de investigación previos y con resultados favorables. Por último, se ha hecho hincapié en las novedades (embodiment y neuronas espejo) que aporta este proyecto con las que se podría acelerar la rehabilitación de los pacientes incidiendo en la plasticidad cerebral. En lo que se refiere al desarrollo del entorno, se ha utilizado el motor de videojuegos Unity 3D, con el que se ha integrado el dispositivo Myo Armband, para capturar el movimiento, y las gafas de realidad virtual Oculus Rift DK2. Durante la terapia, el paciente tiene que superar una serie de niveles definidos por el terapeuta y, para ello, debe realizar un alcance y tocar un botón un número de veces por cada nivel. En cada nivel, el esfuerzo que tiene que realizar el paciente es distinto, dependiendo de la distancia a la que se encuentre el botón (relativa al calibrado previo del paciente) e igualmente, está definido por el terapeuta. También se lleva a cabo un registro de las aceleraciones y del porcentaje de acierto del paciente en un fichero, para llevar un control de su progreso. Como conclusión, cabe mencionar que el entorno desarrollado es adaptable a las posibilidades de cada paciente, permitiendo una recuperación óptima. Se trata de un sistema de bajo coste, intuitivo y que lleva a cabo un registro de datos de la actividad del paciente, lo que posibilita, como trabajo futuro, el control de forma remota por parte del terapeuta. Todos estos aspectos dejan abierta la posibilidad de que el paciente lo utilice a domicilio, con las ventajas que conlleva. Del mismo modo, el sistema se podría adaptar fácilmente para la rehabilitación de las extremidades inferiores. Tras su análisis, los investigadores expertos en la materia del Consejo Superior de Investigaciones Científicas afirman que el sistema satisface con creces su propósito. Con todo esto, se concluye que este entorno tiene un excelente presente y un futuro muy prometedor.

Organización cerebral en el reconocimiento de caras conocidas y no conocidas en niños con autismo

Disponemos hoy de dos sistemas de clasificación diagnóstica: uno el establecido por la Asociación Psiquiátrica Norteamericana, el Manual Diagnóstico y Estadístico de Trastornos Mentales, DSM-IV-TR, (APA, 2002); y otro, el desarrollado por la Organización Mundial de la Salud, la Clasificación Internacional de Enfermedades CIE- 10 (OMS, 1992) en su décima versión, que se utiliza de manera oficial para codificar las enfermedades en muchos países. En el DSM-IV-TR, el autismo viene incluido dentro del grupo de los trastornos generalizados del desarrollo (TGD) como una categoría diagnóstica que tiene su principal afectación en la alteración cualitativa de la interacción social, la flexibilidad, los intereses restringidos, el lenguaje y la imaginación o el juego. En los últimos años, y muy usado actualmente, se incorpora el término trastornos del espectro autista (TEA). Además de los aspectos ya aceptados en la denominación TGD, el término TEA resalta la noción dimensional de un “continuo” (no una categoría), en el que se altera cualitativamente un conjunto de capacidades en la interacción social, la comunicación y la imaginación. Esta semejanza no es incompatible con la diversidad del colectivo: diversos trastornos, diversa afectación de los síntomas clave, desde los casos más acentuados a aquellos rasgos fenotípicos rozando la normalidad; desde aquellos casos asociados a discapacidad intelectual marcada, a otros con alto grado de inteligencia; desde unos vinculados a trastornos genéticos o neurológicos, a otros en los que aún no somos capaces de identificar las anomalías biológicas subyacentes...

Associação entre comprometimento motor, mobilidade e qualidade de vida em crianças com paralisia cerebral espástica, nível I, II e III do Gross Motor Function Classification System

The objective of this study was to verify the association between some mobility items of the International Classification Functionality (ICF), with the evaluations Gross Motor Function Measure (GMFM-88), 1-minute walk test (1MWT) and if the motor impairment influences the quality of life in children with Cerebral Palsy (PC), by using the Paediatric Quality of Life Inventory (PedsQL 4.0 versions for children and parents). The study included 22 children with cerebral palsy spastic, classified in levels I, II, and III on the Gross Motor Function Classification System (GMFCS), with age group of 9.9 years old. Among those who have participated, seven of them were level I, eight of them were level II and seven of them were level III. All of the children and teenagers were rated by using check list ICF (mobility item), GMFM-88, 1-minute walk test and PedsQL 4.0 questionnaires for children and parents. It was observed a strong correlation between GMFM-88 with check list ICF (mobility item), but moderate correlation between GMFM-88 and 1-minute walk test (1MWT). It was also moderate the correlation between the walking test and the check list ICF (mobility item). The correlation between PedsQl 4.0 questionnaires for children and parents was weak, as well as the correlation of both with GMFM, ICF (mobility item) and the walking test. The lack of interrelation between physical function tests and quality of life, indicates that, regardless of the severity of the motor impairment and the difficulty with mobility, children and teenagers suffering of PC spastic, functional level I, II and III GMFCS and their parents have a varied opinion regarding the perception of well being and life satisfaction.

Pelo olhar de quem não sente a diferença : comparação dos Cores Sets da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF) para a Paralisia Cerebral com a perspetiva de crianças/ jovens e cuidadores, de Portugal

Introdução: A CIF foi considerada, por alguns clínicos, como não sendo totalmente viável para a aplicação na rotina clínica, já que este sistema de classificação contém mais de 1400 categorias. Posto isto, o processo de desenvolvimento de Core Sets da CIF tem sido priorizado pela OMS, tornando a CIF acessível para a avaliação das cs específicas. Estes pretendem orientar uma avaliação multidisciplinar abrangente, incluindo as categorias da CIF para descrever, de uma forma suficiente, a funcionalidade e incapacidade dos indivíduos. Contudo, podem existir divergências entre a perspetiva de crianças e jovens portugueses com PC e cuidadores sobre a sua cs e os core sets da CIF estabelecidos para a mesma. Objetivo: Identificar os problemas percecionados pelas crianças e jovens com paralisia cerebral e pelos cuidadores em Portugal e analisar em que medida estes aspetos são representados pela versão atual do Comprehensive Core Set da CIF para esta cs. Metodologia: Este estudo é qualitativo, tendo-se utilizado uma amostra conveniente de crianças/jovens com PC e cuidadores. Todos os dados foram recolhidos por meio de entrevistas e posteriormente analisados segundo o protocolo de Coenen. Foi efetuado o linking dos conceitos obtidos das entrevistas para as categorias da CIF, tendo sido comparadas com os Core Sets da CIF para esta condição. Resultados: Este estudo tem uma amostra de 48 indivíduos, sendo que 28 eram crianças e jovens com PC e os restantes 20 eram cuidadores. A média de idades das crianças/jovens incluídos foi 13,04 (±3,26), sendo que a idade mínima incluída foi 8 anos e a idade máxima, 18 anos. A média de idades dos cuidadores incluídos foi de 35,20 (±8,01) anos, sendo que a idade mínima incluída foi 22 anos e a idade máxima 55 anos. Das 256 categorias identificadas, 101 estão contempladas nas categorias dos Comprehensive Core Set da CIF. Estas encontram-se presentes em 58 categorias de 2º nível dos Comprehensive Core Set de um total de 135, correspondendo a 43% dos mesmos. Conclusões: Tendo em conta os resultados obtidos, podemos concluir que os Comprehensive Core Set da CIF para a PC contemplam a grande maioria dos problemas percecionados pela população-alvo, ainda que integre várias categorias que não foram relevantes para esta população em estudo.
