O Gross Motor Function System Expanded and Revised (GMFCS E & R) e o Manual Ability Classification System (MACS) têm sido amplamente utilizados na pesquisa e na prática clínica como complemento ao diagnóstico da paralisia cerebral (PC). Ambos consistem em cinco níveis, sendo que o nível V indica maior limitação funcional. O objetivo deste estudo foi realizar o processo de tradução e adaptação transcultural do GMFCS E & R e MACS, avaliar a confiabilidade inter-avaliadores (entre terapeutas e entre terapeutas e pais) e intra-avaliadores (terapeutas) acerca dos sistemas de classificação (GMFCS E & R e MACS) e verificar a influência de fatores relacionados à criança (tipo de PC) e aos pais (escolaridade, renda, ocupação e idade) na confiabilidade entre terapeutas e pais. Participaram 100 crianças com PC, que eram acompanhadas pelo serviço de neurologia ou de reabilitação de um hospital terciário no interior paulista na faixa etária entre 4 a 18 anos, e seus pais. Para a aplicação dos sistemas de classificação realização da tradução e adaptação transcultural do GMFCS E & R, seguiram-se seis estágios: tradução, síntese das traduções, retrotradução para língua de origem, comitê de análise, submissão aos autores e pré-teste. A coleta de dados foi feita por dois terapeutas com diferentes níveis de experiência na área de neuropediatria. Os terapeutas classificaram a função motora grossa da criança (GMFCS E & R) através da observação direta (controle de cabeça, tronco, transferências, mobilidade) e os pais responderam ao GMFCS Family Report Questionnaire, onde deveriam selecionar uma opção, dentre cinco, correspondente ao nível motor da criança. Quanto à habilidade manual (MACS), os terapeutas observaram a criança manipulando objetos (brinquedos, alimentação, vestuário) e obtiveram informações dos pais. Os pais realizaram a classificação da habilidade manual da criança com base na leitura do folheto explicativo do MACS. Foram realizadas filmagens das observações das crianças para avaliação da confiabilidade intra-avaliadores (terapeutas), após um mês da avaliação inicial. Utilizou-se o coeficiente Kappa (k) para avaliação da confiabilidade inter-avaliadores (entre terapeutas e entre terapeutas e pais) e intra-avaliadores (terapeutas) acerca do GMFCS E & R e MACS e o teste do qui-quadrado (x2) para verificar a associação entre os fatores relacionados à criança e aos pais. Após realizados os seis estágios referentes à tradução e adaptação transcultural do GMFCS E & R e MACS, as versões em português foram aprovadas pelos autores. Em relação à confiabilidade inter-avaliadores (AV1 e AV2), obteve-se concordância quase perfeita para o GMFCS E & R e MACS (K = 0,902 e 0,90 respectivamente), assim como intra-avaliadores, obtendo-se concordância quase perfeita para ambos avaliadores acerca do GMFCS E & R (k=1,00) e MACS (K= 0,958 para AV1 e K= 0,833 para AV2). Em relação à confiabilidade entre terapeutas e pais, esta foi substancial para GMFCS E & R (K = 0,716) e considerável para MACS (K =0, 368). Em relação ao GMFCS E & R, verificou-se que o porcentual de discordâncias no grupo de pais que não trabalha fora é significativamente superior ao porcentual de discordância de quem trabalha fora (x 2 =4,79; p= 0,03), quando comparada à classificação do terapeuta. Maior freqüência de pais classificaram as crianças como severamente limitada, comparada à classificação do terapeuta (x 2 =4,26; p= 0,04). Em relação ao MACS, verificou-se que as discordâncias entre terapeutas e pais foram significativamente superiores nas crianças de 4 a 6 e 6 a 12 anos do que em relação às crianças de 12 a 18 anos (p=0,05), assim como pais na faixa etária de 20 a 30 anos discordaram significativamente mais do terapeuta (p=0,04). É importante considerar a influência de fatores ambientais no desempenho típico da criança com PC em relação à função motora grossa e habilidade manual. Portanto, embora terapeutas e pais apresentem diferentes perspectivas em relação a tais aspectos, por julgarem diferentes contextos como referência (pais consideram o desempenho em casa, escola, ambientes externos; o terapeuta, o ambiente clínico), os dois pontos de vista necessitam ser apreciados conjuntamente. Conclui-se que as versões traduzidas para o português Brasil do GMFCS E & R, GMFCS Family Report Questionnaire são confiáveis para classificar crianças com PC por pais e terapeutas. / The Gross Motor Function System Expanded and Revised (GMFCS E & R) and Manual Ability Classification System (MACS) has been widely used in research and clinical practice to complement the diagnosis of cerebral palsy (CP). Both consist of five levels where the level V indicates greater functional limitation. The aim of this study was to carry out the process of translation and cultural adaptation of the GMFCS E & R and MACS, evaluate the inter-rater reliability (between therapists and between therapists and parents) and intra-rater (therapists) about rating systems and verify the influence of factors related to the child (type PC) and parents (education, income, occupation and age) in reliability between therapists and parents. Participants 100 children with CP who were accompanied by the department of neurology and rehabilitation of a tertiary hospital in São Paulo aged 4-18 years and their parents. To perform the translation and cultural adaptation of the GMFCS E & MACS, followed by six stages: translation, synthesis of translations, back translation for source language, analysis committee, submission to the authors and pretest. Data collection was done by two therapists with different levels of experience in neuropediatric.Therapists rated the child\'s gross motor function (GMFCS & E) through direct observation (head control, trunk, transfers, mobility) and parents responded to GMFCS Family Report Questionnaire, which should select an option Among five, corresponding to the child\'s motor. As for manual ability (MACS), therapists observed the child handling objects (toys, food and clothing) and obtained information from parents. Parents held the classification of manual ability of the child based on reading the brochure MACS. Were filmed observations of children to assess intra-rater reliability (therapists), one month after the initial evaluations. To assess the reliability used the kappa coefficient (k) and the chi-square (x2) to determine the association between factors related to the child and parents, the reliability between therapists and parents. Performed after the six stages related to translation and cultural adaptation of the GMFCS E & R and MACS, the Portuguese versions were approved by the authors. Regarding inter-rater reliability (AV1 and AV2), we obtained almost perfect agreement for the GMFCS E & R and MACS (K = 0.902 and 0.90 respectively) as well as intra-rater, yielding almost perfect agreement for both evaluators about the GMFCS E & R(k = 1.00) and MACS (K = 0.958 for AV1 and AV2 for K = 0.833). Regarding reliability between therapists and parents, this was substantial for GMFCS E & R (K = 0.716) and to considerable MACS (K = 0, 368). Regarding the GMFCS E & R, it was found that the percentage of disagreements in the group of parents who do not work out is significantly higher than the percentage of those working outside of disagreement (x 2 = 4.79, p = 0.03), compared to ratings of therapist. Parents classify children as more severely limited than therapists (x 2 = 4.26, p = 0.04). It is important to consider the influence of environmental factors on the performance of children with PC in relation to gross motor function and manual ability. Therefore, parents and therapists have different perspectives regarding such aspects, judging by different contexts as reference (parents consider performance at home, school, outdoors, therapist, the clinical setting), the two points of view need to be assessed together. We conclude that the translated versions for Portuguese - Brazil\'s GMFCS E & R, GMFCS Family Report Questionnaire are reliable to classify children with CP by parents and therapists.

O AVC está entre a principais causas de mortalidade e disfuncionalidade no mundo. A recuperação da função motora pós-AVC é normalmente incompleta; uma vez que as terapias atuais tem impacto limitado na promoção da plasticidade cerebral. Novas abordagens que podem intensificar a plasticidade cerebral têm sido estudadas para melhorar a reabilitação motora pós- AVC, entre eles a fluoxetina e a estimulação magnética transcraniana (EMTr) alcançaram resultados promissores. Portanto, nós conduzimos um ensaio clínico exploratório randomizado, duplo-cego, placebo controlado, avaliando os efeitos da combinação da EMTr em baixa frequência com a fluoxetina para aumentar a função motora do membro superior em pacientes com AVC. Vinte e sete pacientes hemiplégicos secundários a AVC isquêmico que apresentaram o evento nos últimos 2 anos foram randomizados em três grupos: EMTr ativa + fluoxetina, sham EMTr + fluoxetina e placebo (sham EMTr + fluoxetina placebo). Os participantes receberem 18 sessões (10 sessões diárias seguidas de 8 sessões semanais) de EMTr a 1 Hz sobre o córtex motor primário (M1) do hemisfério não afetado, combinadas com 90 dias de fluoxetina (20 mg/dia). As escalas de Jebsen Taylor (JTHF) e Fugl-Myer (FMA) foram utilizadas. Além disso, desfechos secundários incluíram questionário de segurança e comportamentais. Nossos resultados demonstraram melhora significativa na FMA e JTHF após o tratamento nos três grupos. Após ajustar para o tempo desde o evento isquêmico houve um aumento significativo na melhora da função motora de acordo com o JTHF no grupo que combinou EMTr ativa + fluoxetina quando comparados os grupos placebo ou fluoxetina exclusivamente. Essa análise mostrou uma melhora menos significativa na função motora no grupo fluoxetina quando comparada com o grupo placebo quando avaliada pelo JTHF (p=0.038) e pelo FMA (p=0.039), sugerindo um efeito potencialmente prejudicial da medicação ativa quando comparada com o placebo. Por fim, observamos que os desfechos de humor, função cognitiva e a segurança não foram significativos. A combinação da EMTr com a fluoxetina demonstrou melhoras significativas na função motora pós-AVC quando comparada com placebo, a terapia exclusiva com fluoxetina parece causar um efeito negativo / Stroke is among the leading causes of mortality and disability worldwide. Post stroke recovery of motor function is usually incomplete; these poor effects are believed to be due to the limited impact of current therapies in promoting brain plasticity. Novel approaches that can enhance brain plasticity have been studied to improve motor rehabilitation after stroke, among them fluoxetine and repetitive transcranial magnetic stimulation (rTMS) yielded promising results. Therefore, we conducted a randomized, double-blinded, sham-controlled, exploratory trial evaluating the effects of the combination of low-frequency rTMS and fluoxetine to increase upper limb motor function in stroke patients. Twenty-seven hemiplegic ischemic stroke patients within 2 years post event were randomized into three groups: active rTMS+fluoxetine, sham rTMS+fluoxetine, or placebo (sham rTMS+ placebo fluoxetine). Participants received 18 sessions (10 daily sessions followed by 8 weekly sessions) of 1Hz rTMS applied over the primary motor cortex (M1) over the unaffected hemisphere combined with 90 days of fluoxetine (20 mg/day). A blinded rater assessed motor function as indexed by Jebsen Taylor hand function (JTHF) and Fugl-Myer (FMA) scales. Additional secondary outcomes included safety and behavioral questionnaires. Our results showed a significant improvement in FMA and JTHF post treatment in all three groups. After adjusting for time since stroke there was a significantly larger improvement in motor function as indexed by JTHF seen in the combined active rTMS+fluoxetine group when compared to placebo and fluoxetine only groups. Additionally, this analysis showed significant less improvement in motor function in the fluoxetine group when compared to placebo group as indexed by JTHF (p=0.038) and FMA (p=0.039); consequently, suggesting a potential detrimental effect of the active medication when compared to placebo. Lastly, we observed that mood, cognitive performance and safety outcomes were not significantly. Despite establishing that the combination of TMS and fluoxetine leads to higher/greater improvements in motor function post stroke when compared to placebo, solely therapy with fluoxetine seemed to lead to a negative effect and thus it is plausible to believe that the benefit observed in the combined group is more likely due to the effects of TMS intervention

Delayed gastric emptying, that manifests clinically as intolerance to enteral feeding, occurs in over 50% of critically ill patients and has a major impact on patient morbidity and mortality. Despite the recognition that the proximal stomach has a major role in gastric emptying of liquids, only the motor activity of the antro-pyloro-duodenal region has been evaluated in detail. In addition, many of the proposed risk factors for the gastric dysmotility, particularly a prior history of diabetes mellitus, have not been evaluated formally but have been extrapolated from data from non-critically ill patients. The currently available prokinetic drugs, erythromycin and metoclopramide, are considered to be the first line treatment for feed intolerance. However, neither data comparing the effectiveness of these agents nor the data on the effects of combination of therapy in the treatment of feed intolerance are available. The aims of this thesis were, therefore, to examine: (i) proximal gastric motor activity and the association between proximal and distal motility; (ii) the relationship between entero-gastric humoral responses to nutrients, gastric emptying and feed intolerance; (iii) the impact of admission diagnoses, choice of sedations, timing of initiation of feeding, and pre-existing history of diabetes mellitus on gastric emptying and feed intolerance; and (iv) the efficacy of erythromycin, metoclopramide and combination of these drugs in treatment of feed intolerance in critically ill patients. The current thesis indicates that motor activity is impaired in multiple regions of the stomach in the critically ill. When compared to healthy humans, proximal gastric relaxation was prolonged and fundic wave activity was educed during small intestinal nutrient infusion in critically ill patients. In addition, simultaneous assessment of proximal and distal gastric motility demonstrated a possible disruption of the motor integration between the proximal and distal stomach. In light of the recent data that suggested a significantly greater proportion of meal distributed proximally in critically ill patients with delayed gastric emptying (Nguyen, et al. 2006), the disruption of the gastric motor integration and the prolonged gastric relaxation in response to duodenal nutrients may play a significant role in the pathogenesis of slow gastric emptying during critical illness, especially as liquid formulae. The entero-gastric hormonal feedback responses were also disturbed during critical illness. Both fasting and duodenal nutrient-stimulated plasma CCK and PYY concentrations were significantly higher in critically ill patients, particularly those who did not tolerated gastric feeds. The rate of gastric emptying of a liquid meal was inversely related to both fasting and postprandial plasma CCK and PYY concentrations, supporting the potential role of plasma CCK and PYY in the pathogenesis of gastric dysmotility in critically ill patients. Admission diagnosis, choice of sedative drug and blood glucose control but not the timing of enteral feeds were important factors for delayed gastric emptying and feed intolerance in these patients. In particular, delaying enteral feeding by 4 days had no impact on the rate of gastric emptying, intra-gastric meal distribution, or plasma CCK and PYY concentrations. Contrary to traditional belief, critically ill patients with a pre-existing diagnosis of type 2 DM have only a minor disturbance to the proximal stomach, a relatively normal gastric emptying and are at no higher risk of feed intolerance than those without DM, suggesting the presence of pre-existing DM 2 in critically ill patients should not influence the standard practice of gastric feeding. Therapeutically, short-term treatment with low dose erythromycin was more effective than metoclopramide, but the effectiveness decreased rapidly overtime at similar rate as observed with metoclopramide. In patients who failed to response to either agent, treatment with both agents was highly effective in re-establishing feeding success. The use of combination therapy as the initial treatment for feed intolerance was also more effective than erythromycin alone and had less tachyphylaxis. Treatment with erythromycin and metoclopramide, either as a single agent or in combination did not associated with major cardiovascular adverse side effects. Although diarrhoea was a common side effect and was highest with combination therapy, it was not associated with Clostridium difficile infection and settled quickly after the cessation of the prokinetic therapy. In summary, the work performed in the current thesis has provided substantial insights into the understanding of the nature, risk factors, pathogenesis and treatment of disturbed gastric motor function in critically ill patients. Not only do these findings stimulate further research into the mechanisms responsible for gastric dysmotility in critical illness, they also lead to the development of new strategies for optimizing the management of feed intolerance. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1320667 / Thesis (Ph.D.) -- University of Adelaide, School of Medicine, 2008

INTRODUCTION AND BACKGROUND: Cerebral palsy (CP) is the most common physical disability in childhood with a prevalence of approximately 2-2.5 per 100 live births. Improvements in paediatric care have increased the survival of individuals with CP. Overall 90% are expected to grow into adulthood yet little is known about the outcomes of young adults with this condition. In order to provide holistic services for this population, an understanding of various aspects of their lives is required. / AIMS: To examine the outcome of young adults with CP from the perspective of perceived health status, functional ability, pain, quality of life (QOL), social participation, and healthcare service utilizations, compared with their able-bodied peers. To explore the determinants that contribute to the variation of these outcomes in the context of impairments, activity, participation, and personal and environmental factors. / METHODS: This is a population based cross sectional study of young adults with CP based on the WHO International Classification of Functioning, Disability and Health (ICF) model. A cohort of 335 young adults with cerebral palsy born in Victoria, aged 20 to 30 years, was recruited from the Victorian Cerebral Palsy Register. Data of typically developed peers selected from the Household, Income and Labour Dynamics in Australia Survey 2004 were used for comparison for the outcomes of perceived health, pain, and social participation. Data from a population-based sample of 751 young adults in U.S. were used for comparative analyses of QOL. Participants were asked to complete a multidimensional questionnaire by self report, or proxy report by parents or carers for those with intellectual or severe physical impairments. The questionnaire was comprised of the Quality of Life Instrument for Young Adults, the Short Form-36 Health Survey Questionnaire version 2, the Gross Motor Function Classification System, the Barthel Index, and a demographic section. / RESULTS: A total of 335 young adults with CP participated; 207 (62%) were able to self report and 128 (38%) were proxy reported. Compared with their able-bodied peers, self reported physical health in this population was lower but mental health was similar. Gross motor function, independence in self care, and limb distribution together explained 60% of the variance in the physical health data. They experienced more pain, impaired function, and reduced social participation, but despite this, their contact with medical and allied health professionals was low. Pain was linked with limb distribution and had a negative impact on functional ability, employment participation and QOL. Impaired functional ability, intellectual disability, and communication impairments had major effects in reducing social participation. Self reported QOL was similar to their peers in social relationship and environmental context domains, but was lower in the domains of physical health, psychological well-being, and role function. The impact of CP on the individuals’ QOL was on physical and functional aspects, and sometimes on social relationships, but not on psychological well-being. / CONCLUSION: This study has demonstrated that greater efforts are needed to improve the health, function, QOL, and social participation in individuals with CP, accompanied by more research to monitor the effectiveness of interventions for them.

Dentre as características deste quadro encontram-se também queixas de distúrbios de sono, com causas ainda não totalmente elucidadas e que possivelmente prejudicam o desempenho motor e cognitivo nesta população. Apesar da importância, ainda não está claro o quanto aspectos da comunicação e do desenvolvimento motor poderiam estar comprometidos pela presença de distúrbios de sono na PC. Dentre as possíveis causas para distúrbios de sono em diversos quadros patológicos está o déficit na produção do hormônio melatonina, fato que também ainda não foi investigado nessa população. O objetivo deste estudo foi caracterizar e correlacionar aspectos motores, de comunicação, os distúrbios de sono e o conteúdo de melatonina em indivíduos com PC. Para isso foram avaliados 33 indivíduos com PC, de 2 a 15 anos de idade, classificados pelos sistemas de classificação de função motora grossa (GMFCS), e de função de comunicação (CFCS) e por questionários de sono. O teor de melatonina foi analisado por kits comerciais ELISA. Os resultados indicaram que: 9% dos indivíduos com PC nível I; 18% nível II; 24,5% nível III; 15% nível IV e 33,5% nível V no GMFCS. 30,5% dos indivíduos com PC apresentaram nível I; 12% nível II, 12% nível III; 0% nível IV e 45,5% nível V em função de comunicação. Os distúrbios do sono foram encontrados em 78% das crianças com PC. O grupo PC apresentou menor conteúdo de melatonina noturna que os controles. As análises de correlação mostraram que quanto maior a deficiência motora, maior o comprometimento da comunicação e piores os distúrbios de sono. Além disso, quanto maior o índice da escala de distúrbio de sono pior o desempenho funcional motor em relação ao que era esperado para cada indivíduo. Todas as crianças do grupo PC que apresentaram distúrbios de sono apresentaram também déficits no conteúdo de melatonina. Os resultados permitem concluir que houve uma relação direta entre as características motoras e de comunicação, entre os baixos níveis de melatonina e os distúrbios de sono e entre os distúrbios de sono e as habilidades motoras na PC. / Cerebral palsy (CP) encompasses a set of changes in tone, posture and movements resulting in functional limitations at different levels attributed to non-progressive frames that occurred in the fetal development or the child´s still immature brain. Among the characteristics of this picture are also complaints of sleep disorders, with causes not yet fully elucidated and possibly impair motor and cognitive performance in this population, despite the importance, it is still not clear how much aspects of communication and motor development could be compromised by the presence of sleep disorders in the CP. Among the possible causes for sleep disorders in several pathological conditions is the deficit in the production of the hormone melatonin, a fact that has not yet been investigated in this population. The objective of this study was to characterize and correlate motor, communication, sleep disorders and melatonin content in individuals with CP. For this purpose, 33 individuals with CP, 2 to 15 years of age, classified by gross motor function classification (GMFCS), and communication function (CFCS) and sleep questionnaires were evaluated. The melatonin content was analyzed by commercial ELISA kits. The results indicated that: 9% of individuals with CP level I; 18% level II; 24,5% level III; 15% level IV and 33,5% level V in GMFCS. 30,5% of individuals with CP had Level I; 12% level II; 12% level III; 0% level IV and 45,5% level V as function of communication. Sleep disturbances were found in 78% of children with CP. The CP group had lower nocturnal melatonin content than controls. Correlation analyzes showed that the greater the motor impairment the greater the impairment of communication and the worse the sleep disorders. In addition, the higher the index of sleep disturbance scale the worse the motor functional performance compared to what was expected for each individual. All children in the CP group who presents sleep disorders also presented deficits in melatonin content. The results allow us to conclude that there was direct relationship between motor and communication characteristics, between low levels of melatonin and sleep disorders, and between sleep disorders and motor skills in CP.

Motor Function Evaluation of Hydrocephalus Children Background: Hydrocephalus constitutes a pathological condition that is manifested through signals and symptoms, including neurological and motor deficits that can result functional ability limitations. However, there are few studies that show the motor function of children with this illness. Objectives: To evaluate the kinetic and functional framework of hydrocephalus children; to identify the condition of muscle tone; to check the static and dynamic functional activities; to verify the association between tone alterations and functional activities in hydrocephalus children. Methods: A cross-sectional, descriptive, exploratory and field study, using qualitative and quantitative approach, performed at the University Hospital in Aracaju city, from August 2009 to March 2010. Results: From 50 evaluated children, 30 (60%) had hypertonia; 10 (20%) were hypotonic; and 10 (20%) showed no muscle tone alteration. The age average was considerably lower in hypertonic children and higher in hypotonic and without tone alteration children. The average of carried through surgeries was more expressive in hypertonic children. Motor sequels were present in 92% of the sample. The static functional activities, as well as dynamic ones, were lower in hypertonic children and higher in hypotonic and normal tone children. Conclusions: Muscle tone exacerbation is more present in hydrocephalus children and motor function is impaired, being the neuropsychomotor development delayed more evident in spastic children group and less pronounced in children with normal muscle tone. / Fundamento: A hidrocefalia constitui uma condição patológica que se manifesta através de sinais e sintomas, incluindo déficits neuromotores que podem resultar em limitações nas habilidades funcionais. No entanto, há poucos estudos que avaliem a função motora de crianças com esta doença. Objetivos: Avaliar o quadro cinético-funcional de crianças com hidrocefalia; identificar a condição do tônus muscular; verificar as atividades funcionais estáticas e dinâmicas; verificar a associação entre as alterações de tônus e as atividades funcionais nas crianças com hidrocefalia. Métodos: Estudo transversal, de caráter descritivo, exploratório e de campo, sob abordagem quali-quantitativa, realizado no ambulatório do Hospital Universitário, do município de Aracaju, no período de agosto de 2009 a março de 2010. Resultados: Das 50 crianças avaliadas, 30 (60%) apresentavam hipertonia; 10 (20%) eram hipotônicas; e 10 (20%) não apresentavam alteração de tônus muscular. A média de idade foi consideravelmente menor nas crianças hipertônicas em relação às crianças hipotônicas e normotônicas. O número de procedimentos cirúrgicos realizados foi mais expressivo no grupo de crianças com hipertonia muscular. As sequelas motoras estiveram presentes em 92% da amostra. As atividades funcionais estáticas, bem como as dinâmicas, encontraram-se mais comprometidas nas crianças hipertônicas do que nas hipotônicas e normotônicas. Conclusões: A hipertonia muscular foi a alteração tônica mais presente nas crianças com hidrocefalia, e a função motora é deficitária, sendo o atraso no desenvolvimento neuropsicomotor mais evidente no grupo de crianças espásticas e menos pronunciado nas crianças com tônus muscular sem alterações.

O Gross Motor Function System Expanded and Revised (GMFCS E & R) e o Manual Ability Classification System (MACS) têm sido amplamente utilizados na pesquisa e na prática clínica como complemento ao diagnóstico da paralisia cerebral (PC). Ambos consistem em cinco níveis, sendo que o nível V indica maior limitação funcional. O objetivo deste estudo foi realizar o processo de tradução e adaptação transcultural do GMFCS E & R e MACS, avaliar a confiabilidade inter-avaliadores (entre terapeutas e entre terapeutas e pais) e intra-avaliadores (terapeutas) acerca dos sistemas de classificação (GMFCS E & R e MACS) e verificar a influência de fatores relacionados à criança (tipo de PC) e aos pais (escolaridade, renda, ocupação e idade) na confiabilidade entre terapeutas e pais. Participaram 100 crianças com PC, que eram acompanhadas pelo serviço de neurologia ou de reabilitação de um hospital terciário no interior paulista na faixa etária entre 4 a 18 anos, e seus pais. Para a aplicação dos sistemas de classificação realização da tradução e adaptação transcultural do GMFCS E & R, seguiram-se seis estágios: tradução, síntese das traduções, retrotradução para língua de origem, comitê de análise, submissão aos autores e pré-teste. A coleta de dados foi feita por dois terapeutas com diferentes níveis de experiência na área de neuropediatria. Os terapeutas classificaram a função motora grossa da criança (GMFCS E & R) através da observação direta (controle de cabeça, tronco, transferências, mobilidade) e os pais responderam ao GMFCS Family Report Questionnaire, onde deveriam selecionar uma opção, dentre cinco, correspondente ao nível motor da criança. Quanto à habilidade manual (MACS), os terapeutas observaram a criança manipulando objetos (brinquedos, alimentação, vestuário) e obtiveram informações dos pais. Os pais realizaram a classificação da habilidade manual da criança com base na leitura do folheto explicativo do MACS. Foram realizadas filmagens das observações das crianças para avaliação da confiabilidade intra-avaliadores (terapeutas), após um mês da avaliação inicial. Utilizou-se o coeficiente Kappa (k) para avaliação da confiabilidade inter-avaliadores (entre terapeutas e entre terapeutas e pais) e intra-avaliadores (terapeutas) acerca do GMFCS E & R e MACS e o teste do qui-quadrado (x2) para verificar a associação entre os fatores relacionados à criança e aos pais. Após realizados os seis estágios referentes à tradução e adaptação transcultural do GMFCS E & R e MACS, as versões em português foram aprovadas pelos autores. Em relação à confiabilidade inter-avaliadores (AV1 e AV2), obteve-se concordância quase perfeita para o GMFCS E & R e MACS (K = 0,902 e 0,90 respectivamente), assim como intra-avaliadores, obtendo-se concordância quase perfeita para ambos avaliadores acerca do GMFCS E & R (k=1,00) e MACS (K= 0,958 para AV1 e K= 0,833 para AV2). Em relação à confiabilidade entre terapeutas e pais, esta foi substancial para GMFCS E & R (K = 0,716) e considerável para MACS (K =0, 368). Em relação ao GMFCS E & R, verificou-se que o porcentual de discordâncias no grupo de pais que não trabalha fora é significativamente superior ao porcentual de discordância de quem trabalha fora (x 2 =4,79; p= 0,03), quando comparada à classificação do terapeuta. Maior freqüência de pais classificaram as crianças como severamente limitada, comparada à classificação do terapeuta (x 2 =4,26; p= 0,04). Em relação ao MACS, verificou-se que as discordâncias entre terapeutas e pais foram significativamente superiores nas crianças de 4 a 6 e 6 a 12 anos do que em relação às crianças de 12 a 18 anos (p=0,05), assim como pais na faixa etária de 20 a 30 anos discordaram significativamente mais do terapeuta (p=0,04). É importante considerar a influência de fatores ambientais no desempenho típico da criança com PC em relação à função motora grossa e habilidade manual. Portanto, embora terapeutas e pais apresentem diferentes perspectivas em relação a tais aspectos, por julgarem diferentes contextos como referência (pais consideram o desempenho em casa, escola, ambientes externos; o terapeuta, o ambiente clínico), os dois pontos de vista necessitam ser apreciados conjuntamente. Conclui-se que as versões traduzidas para o português Brasil do GMFCS E & R, GMFCS Family Report Questionnaire são confiáveis para classificar crianças com PC por pais e terapeutas. / The Gross Motor Function System Expanded and Revised (GMFCS E & R) and Manual Ability Classification System (MACS) has been widely used in research and clinical practice to complement the diagnosis of cerebral palsy (CP). Both consist of five levels where the level V indicates greater functional limitation. The aim of this study was to carry out the process of translation and cultural adaptation of the GMFCS E & R and MACS, evaluate the inter-rater reliability (between therapists and between therapists and parents) and intra-rater (therapists) about rating systems and verify the influence of factors related to the child (type PC) and parents (education, income, occupation and age) in reliability between therapists and parents. Participants 100 children with CP who were accompanied by the department of neurology and rehabilitation of a tertiary hospital in São Paulo aged 4-18 years and their parents. To perform the translation and cultural adaptation of the GMFCS E & MACS, followed by six stages: translation, synthesis of translations, back translation for source language, analysis committee, submission to the authors and pretest. Data collection was done by two therapists with different levels of experience in neuropediatric.Therapists rated the child\'s gross motor function (GMFCS & E) through direct observation (head control, trunk, transfers, mobility) and parents responded to GMFCS Family Report Questionnaire, which should select an option Among five, corresponding to the child\'s motor. As for manual ability (MACS), therapists observed the child handling objects (toys, food and clothing) and obtained information from parents. Parents held the classification of manual ability of the child based on reading the brochure MACS. Were filmed observations of children to assess intra-rater reliability (therapists), one month after the initial evaluations. To assess the reliability used the kappa coefficient (k) and the chi-square (x2) to determine the association between factors related to the child and parents, the reliability between therapists and parents. Performed after the six stages related to translation and cultural adaptation of the GMFCS E & R and MACS, the Portuguese versions were approved by the authors. Regarding inter-rater reliability (AV1 and AV2), we obtained almost perfect agreement for the GMFCS E & R and MACS (K = 0.902 and 0.90 respectively) as well as intra-rater, yielding almost perfect agreement for both evaluators about the GMFCS E & R(k = 1.00) and MACS (K = 0.958 for AV1 and AV2 for K = 0.833). Regarding reliability between therapists and parents, this was substantial for GMFCS E & R (K = 0.716) and to considerable MACS (K = 0, 368). Regarding the GMFCS E & R, it was found that the percentage of disagreements in the group of parents who do not work out is significantly higher than the percentage of those working outside of disagreement (x 2 = 4.79, p = 0.03), compared to ratings of therapist. Parents classify children as more severely limited than therapists (x 2 = 4.26, p = 0.04). It is important to consider the influence of environmental factors on the performance of children with PC in relation to gross motor function and manual ability. Therefore, parents and therapists have different perspectives regarding such aspects, judging by different contexts as reference (parents consider performance at home, school, outdoors, therapist, the clinical setting), the two points of view need to be assessed together. We conclude that the translated versions for Portuguese - Brazil\'s GMFCS E & R, GMFCS Family Report Questionnaire are reliable to classify children with CP by parents and therapists.
