Theoretical-Methodological Foundations for the Global Integration Method (Método de Integração Global-MIG) in the Treatment of Autism Spectrum Disorder.

Currently, there is no intervention model for autism spectrum disorder (ASD) that addresses all levels and factors of the International Classification of Functioning, Disability and Health (ICF, WHO). The most researched programs focus on naturalistic, developmental and behavioral approaches to socio-communication. Less attention has been paid to motor and environmental reactivity aspects (behavior/interest restriction and sensory reactivity). The evidence rationale for the Global Integration Method (MIG, "Método de Integração Global"), a model addressing sensorimotor reactivity in addition to socio-communication, is presented. MIG is an integrative, interdisciplinary, family-oriented intervention and naturalistic program that addresses all levels and moderating factors of ASD's impact. MIG's theoretical rationale is based on the predictive coding impairment and embodied cognition hypotheses. MIG incorporates both bottom-up (flexible therapeutic suit, social-motor synchronization) and top-down (schematic social information processing, narratives, imagery) strategies to promote the building and use of accurate, flexible and context-sensitive internal predictive models. MIG is based on the premises that predictive coding improves both socio-communication and environmental reactivity, and that the postural stabilization provided by the flexible therapeutic suit frees information processing resources for socio-cognitive learning. MIG builds on interdisciplinary, professionally and parentally mediated work based on behavioral principles of intensive training in a situated environment.

What are the barriers and facilitators to participation of people with Down syndrome? A scoping review.

AIM: To determine the barriers and facilitators of active community participation of children, adolescents, and adults with Down syndrome. METHOD: Searches were completed in five electronic databases to identify original studies about participation of children, adolescents (ages < 18 years), and adults (ages 18-59 years) with Down syndrome. Barriers and facilitators to participation were categorized into four factors: personal, social, environmental, and policy and programme. Findings were analysed and validated by a young adult with Down syndrome and a family member, using the public and patient involvement strategy. RESULTS: Fourteen studies were included: eight with children and adolescents and six with adults. Of the 14 studies, 10 were qualitative and four quantitative. Most studies (n = 9) investigated participation in physical activities, while only a few examined participation in community/social activities (n = 3), daily activities (n = 2), and leisure activities (n = 1). The most commonly cited barriers and facilitators were the availability of programmes and specialized professionals, transportation, as well as attitudes and behaviours. Physical and psychological characteristics of people with Down syndrome and facilities were also frequently mentioned as barriers. On the other hand, the desire to stay active and personal interest in the activity were among the most frequently reported facilitators. INTERPRETATION: The participation of people with Down syndrome is mainly influenced by physical or psychological factors, the support and attitudes of parents/caregivers, and the availability of specialized programmes. Given the scarcity of research investigating the participation of people with Down syndrome in community activities, daily activities, and leisure, especially in adults, more studies are still needed.

Quais são as barreiras e facilitadores para a participação de pessoas com Síndrome de Down? Uma Revisão de Escopo.

OBJETIVO: Determinar as barreiras e facilitadores da participação ativa na comunidade de crianças, adolescentes e adultos com Síndrome de Down (SD). Métodos: Foram realizadas buscas em cinco bases de dados eletrônicas para identificar estudos originais sobre a participação de crianças, adolescentes (idades <18 anos) e adultos (idades de 18 a 59 anos) com SD. Barreiras e facilitadores para a participação foram categorizados em fatores: pessoais, sociais, ambientais e de políticas e programas. Os achados foram analisados e validados por um jovem adulto com SD e um membro da família, utilizando a estratégia de Envolvimento do Público e Paciente. RESULTADOS: Quatorze estudos foram incluídos, oito com crianças e adolescentes e seis com adultos. Dos 14 estudos, dez eram qualitativos e quatro quantitativos. A maioria dos estudos (n = 9) investigou a participação em atividades físicas, enquanto apenas alguns estudos examinaram a participação em atividades comunitárias/sociais (n = 3), atividades diárias (n = 2) e atividades de lazer (n = 1). As barreiras e facilitadores mais frequentemente citados foram a disponibilidade de programas e profissionais especializados, transporte, bem como atitudes e comportamentos. As características físicas e psicológicas das pessoas com SD e as instalações também foram frequentemente mencionadas como barreiras. Por outro lado, o desejo de se manter ativo e o interesse pessoal na atividade estavam entre os facilitadores mais frequentemente relatados. INTERPRETAÇÃO: A participação de pessoas com SD é principalmente influenciada por fatores físicos ou psicológicos, o apoio e as atitudes dos pais/cuidadores e a disponibilidade de programas especializados. Dada a escassez de pesquisas investigando a participação de pessoas com SD em atividades comunitárias, atividades diárias e lazer, especialmente em adultos, mais estudos ainda são necessários.

Characterization of environmental factors in children and adolescents with cerebral palsy in Minas Gerais: Participa Minas.

OBJECTIVE: To characterize the environmental factors of children and adolescents with Cerebral Palsy (CP) in the state of Minas Gerais (MG), Brazil. METHODS: This is a cross-sectional study involving 164 caregivers of children/adolescents with CP, aged 1-14 years. The Gross Motor Function Classification System (GMFCS) and the Manual Ability Classification System (MACS) were used to classify the participants' functioning, and environmental factors were evaluated by an on-line questionnaire that examined products and technologies, physical environment, services, and systems. A descriptive analysis was performed using percentage and frequency. RESULTS: Most participants had bilateral CP (66.9%) and 45% of them were spastic. Levels II and V of the GMFCS and MACS were the most frequent. About half (49.4%) used anticonvulsants, 27.4% underwent botulinum toxin application, and 29% went through orthopedic surgery in the lower limbs. Among the participants, 71.3% used orthoses in the lower limbs, and 51.8% used the public health care system. Most had access to physiotherapy (91.5%), but found difficulties to access interventions with other professionals, such as psychologists (28%) and nutritionists (37.8%). The school was the most frequently adapted environment (78%), and had the highest level of structural adaptation (42.7%). CONCLUSIONS: The results of this study suggest that the barriers to access health services and barriers to the physical environment may impact participation and social inclusion.

Analysis of the Brazilian-Portuguese Content on Autism Spectrum Disorder Available on YouTube Videos.

AIMS: Information about Autism Spectrum Disorder (ASD) is available in different videos on YouTube. However, these videos might present inaccurate or outdated information. The aims of this study were to 1) identify characteristics of Brazilian-Portuguese videos about ASD (i.e., type of content, number of views, likes, and dislikes); 2) analyze the content of informative videos about ASD, by assessing their trustworthiness and overall quality; and 3) investigate the most popular topics of informative videos about ASD over time. METHODS: This is a cross-sectional study that investigated Brazilian-Portuguese ASD content on YouTube. Videos were selected by two examiners and categorized as experiential or informative. The Discern checklist and the Global Quality Score (GQS) were used to analyze the trustworthiness and quality of informative videos. RESULTS: In total, 216 videos were analyzed, of which 19.5% and 85% were classified as experiential and informative, respectively. The majority of informative videos presented moderate trustworthiness and quality. Videos about ASD clinical aspects were the most popular. CONCLUSION: YouTube offers a large number of experiential and informative videos on ASD. However, some of these videos fail to present reliable and additional sources of information for stakeholders. Efforts to promote knowledge translation about ASD on YouTube are necessary.

Sports Stars Brazil in children with autism spectrum disorder: A feasibility randomized controlled trial protocol.

BACKGROUND: Autism Spectrum Disorder (ASD) children have lower levels of participation in recreational and sporting activities when compared to their peers. Participation has been defined based on the Family of Participation-Related Constructs (fPRC) which defines participation as including both attendance and involvement, with sense of self, preferences and activity competence related to a child's participation. Modified sports interventions such as Sports Stars can act on physical literacy and some of the fPRCs components. This study aims to assess the feasibility of the Sports Stars Brazil intervention for children with ASD. METHODS: This study will be conducted with 36 participants with ASD aged 6 to 12 years old following the CONSORT for pilot and feasibility recommendation. Participants will be randomly allocated into two groups. Intervention group will receive eight, weekly Sports Stars sessions. Each session will include of sports-focused gross motor activity training, confidence building, sports-education and teamwork development. Study assessments will occur at baseline, immediately post-intervention and 20-weeks post-randomization. First, we will assess process feasibility measures: recruitment, assessment completion, adherence, adverse events and satisfaction. Second, we will investigate the scientific feasibility of the intervention by estimating the effect size and variance at the level of achievement sports-related activity and physical activity participation goals (Goal Attainment Scaling), activity competence (Ignite Challenge, Test of Gross Motor Development-second edition, Physical Literacy Profile Questionnaire, Pediatric Disability Assessment Inventory-Computer Adaptive Test-PEDI-CAT-mobility, 10×5 Sprint Test and Muscle Power Sprint Test), sense of self (PEDI-CAT-responsibility), and overall participation at home, school and community, (Participation and Environment Measure for children and young people, PEM-CY). DISCUSSION: The results of this feasibility study will inform which components are critical to planning and preparing a future RCT study, aiming to ensure that the RCT will be feasible, rigorous and justifiable. TRIAL REGISTRATION: The trial was registered with the Brazilian Registry of Clinical Trials database (ID: RBR-9d5kyq4) on June 15, 2022.

I Would Like to Do It Very Much! Leisure Participation Patterns and Determinants of Brazilian Children and Adolescents With Physical Disabilities.

PURPOSE: To describe the patterns, preferences, and predictors of participation in leisure activities of children and young people with physical disabilities from Brazil. METHODS: This is a cross-sectional study that included 50 children/young people with physical disabilities from the southeast of Brazil. The children were assessed using the Children's Assessment of Participation and Enjoyment and Preferences for Activities. RESULTS: Children/young people participated in an average of 38% of the activities, with a greater number and frequency of informal, recreational, social, and self-improvement activities. The average frequency of participation in the activities was twice in the previous 4 months. The enjoyment in the participated activities was high. There was a greater preference for recreational, social, and physical activities. Age and functional classification were predictors of participation. CONCLUSION: This study of children with disabilities from the southeast of Brazil supports studies in other low- and middle-income countries, demonstrating low diversity and intensity of participation in leisure activities, but with high levels of enjoyment.

Practitioner-led, peer-group sports intervention combined with a context-focused intervention for children with cerebral palsy: a protocol of a feasibility randomised clinical trial.

BACKGROUND: There is a need to investigate relevant, acceptable and feasible approaches that promote participation in leisure-time physical activity for children with cerebral palsy (CP). The aim of this study is to assess the feasibility of a randomised controlled trial comparing a peer-group intervention focused on improving physical literacy (Sports Stars) with the combination of Sports Stars and a context-focused intervention (Pathways and Resources for Engagement and Participation, PREP) for ambulant children with CP in Brazil. METHODS: In this feasibility trial, 18 ambulant children (aged 6-12 years) with CP will be randomised into two groups (nine per group): (1) Sports Stars and (2) Sports Stars plus PREP. The Sports Stars group will receive 8 weekly group sessions, focusing on developing the physical, social, cognitive and psychological skills required to participate in popular Brazilian sports. The combined Sports Stars and PREP group will receive Sports Stars in addition to eight individual PREP sessions focused on overcoming environmental barriers to participation. The primary outcome will include feasibility measures: willingness to participate in an RCT, eligibility and recruitment rates, maintenance of evaluator blinding, acceptability of screening procedures and random allocation, feasibility of evaluating outcomes, contamination between the groups, intervention adherence, treatment satisfaction, understanding of the intervention and implementation resources. Additional instruments will be applied to obtain data related to leisure-time physical activity participation goals, overall participation (home, school and community), physical literacy, level of physical activity and family empowerment. Outcomes will be assessed before, after and 12 weeks after intervention. ETHICS AND DISSEMINATION: This feasibility trial has been approved by ethical Federal University of Minas Gerais' Ethics Review Committee (CAAE: 33238520.5.0000.5149). All potential subjects will provide written informed consent. The results of this study will be published in peer-reviewed journals and be presented at academic conferences. TRIAL REGISTRATION NUMBERS: RBR-4m3b4b6, U1111-1256-4998.

Effectiveness of Physical Therapy Interventions in Children with Brachial Plexus Birth Injury: A Systematic Review.

AIM: To systematically review the effectiveness of physical therapy interventions in infants, children and adolescents with brachial plexus birth injury (BPBI). METHODS: Systematic review of randomized controlled trials including patients under 18 years old with BPBI was conducted on Medline, Cochrane, Embase, Amed and Pedro databases. Methodological quality was assessed by the PEDro score and quality of evidence by the GRADE system. The primary outcomes measured were range of motion, muscle strength and bone mineral density. RESULTS: Seven studies were included, two in infant and 5 in children, of 932 title and abstracts screened. The interventions, characteristics of the participants and outcomes were diverse. The largest effect was found when other intervention was combined with conventional physical therapy in the primary outcomes, with low quality of evidence. CONCLUSION: Physical therapy interventions alone or in combination with other treatment modalities are effective in improving short-term disabilities in children with BPBI.

Moving together is better: a systematic review with meta-analysis of sports-focused interventions aiming to improve physical activity participation in children and adolescents with cerebral palsy.

PURPOSE: To analyze the effectiveness of sports-focused interventions on the participation of children and adolescents with cerebral palsy (CP). METHODS: Study searches were conducted on EMBASE, PubMed, Scielo, PEDro, CINAHL, SPORTDiscuss in June 2022. We included randomized controlled trials that investigated the effectiveness of sports-focused interventions in children and adolescents with CP in comparison with control. Risk of bias was assessed with PEDro scale and evidence certainty with GRADE approach. Data were pooled in random-effects meta-analyses and results were presented as standardized mean differences. RESULTS: Ten RCTs were selected with different modalities, mostly for ambulant children and adolescents. Significant pooled effects on participation in leisure-time physical activity were seen only in group interventions (modified sports, gross motor training, and fitness training), in comparison with control [SMD(95% CI) = 0.32(0.01-0.73) p = 0.04]. No pooled effects were seen in participation in other life areas in comparison with control (p > 0.05). Current certainty of evidence of all sports-focused interventions included was moderate due to imprecision. CONCLUSION: Positive results on leisure-time participation were seen at short-term follow-up for group interventions. Sports-focused interventions did not improve participation in other life areas, reinforcing the importance of specificity when conducting participation interventions. Studies investigating sports-focused interventions including non-ambulatory individuals are still necessary. IMPLICATIONS FOR REHABILITATIONSports-focused interventions target leisure-time physical activity participation.They present moderate evidence of their effectiveness to improve physical activity participation in individuals with cerebral palsy.Group interventions are effective in improving leisure-time physical activity participation.Sports-focused interventions did not improve participation in other life areas.

A eficácia da terapia de movimento induzido por contensão em crianças menores de 3 anos: uma revisão sistemática / The efficacy of restraint-induced movement therapy in children under 3 years of age: asystematic review

Introdução: A terapia de movimento induzido por contensão (TMIC) é a abordagem de tratamento mais utilizada na reabilitação do membro superior de crianças com Paralisia Cerebral Unilateral (PCU) e Paralisia Braquial Perinatal (PBP). Protocolos adaptados da TMIC (Baby-TMIC) têm sido utilizados em crianças menores que três anos, porém seus benefícios não são totalmente conhecidos. Objetivo: Avaliar a eficácia da Baby-TMIC na reabilitação do membro superior de crianças com comprometimentos unilaterais menores que 3 anos de idade. Métodos: Trata-se de uma revisão sistemática. A busca e a seleção dos estudos foram realizadas por dois investigadores independentes durante o período de maio de 2021, nas bases Pubmed, Embase, PEDro, Lilacs e Scielo. A escala PEDro foi utilizada para avaliar a qualidade metodológica dos estudos. A qualidade geral das evidências e a força das recomendações foram avaliadas pela GRADE. Resultados: Cinco estudos foram incluídos e incorporaram um total de 190 crianças, com idade variando de 6 a 30 meses. Quatro estudos envolveram crianças com PCU e apenas um estudo envolveu crianças com PBP. Os escores da escala PEDro variaram de 5 a 7, com média 5,8 pontos. A Baby-TMIC resultou em melhorias no desempenho bimanual, unimanual, função motora grossa, atividades de vida diária e movimentação ativa. A qualidade da evidência variou de baixa a muito baixa. Conclusão: Esta revisão fornece as evidências mais atualizadas sobre a eficácia da Baby-TMIC na reabilitação do membro superior de crianças com PCU e PBP menores de 3 anos.

Body experience influences lexical-semantic knowledge of body parts in children with hemiplegic cerebral palsy.

Background: Disorders in different levels of body representation (i.e., body schema, body structural description, and body image) are present in hemiplegic cerebral palsy (HCP). However, it remains unclear whether the body image develops from aspects of body schema and body structural description, and how this occurs in children with HCP. Objective and methods: In a cross-sectional study, we investigated 53 children with HCP (mean age about 10 years) and 204 typically developing (TD) control children to qualitatively evaluate whether and how body schema (related sensorimotor experiences) and body structural description (related visuospatial experiences) affect the development of children's body image and whether this development is delayed through HCP. Graph analysis was used to create a lexical-semantic map of body representation from data of a semantic word fluency task. Results: Results indicated a similar qualitative pattern of influences of sensorimotor and visuospatial experiences on lexical-semantic knowledge of body parts, with a delayed developmental course in children with HCP compared to TD children. Conclusion: These findings suggest that children's body image seemed to be influenced by body schema and body structural descriptions as indicated by poorer lexical-semantic knowledge of body parts in children with HCP due to missing physical experiences of the affected body parts. This might imply that "body talk" may beneficially complement physical therapy for children with HCP to promote body image development.

Neuromotor examination in unilateral cerebral palsy: Bilateral impairments in different levels of motor integration.

Unilateral cerebral palsy (UCP) usually results in damage to the unilateral pyramidal system. However, the clinical presentation of neuromotor deficits also suggests lesions to the extrapyramidal and cerebellar systems bilaterally. In this study, we developed and tested a behavioral neuromotor examination protocol assessing impairments at three levels of motor integration for children with UCP, also considering impairments of the non-paretic upper limb as well as the influences of the laterality of the lesion. We included 30 children with UCP (10.79 ± 2.61 years) and 60 healthy children (8.27 ± 1.57 years) in the study. All children were assessed on general cognitive ability and classified according to the manual ability classification system (MACS). Our neuromotor examination protocol incorporated specific tasks for each level of motor integration: pyramidal, extrapyramidal and cerebellar. Children with UCP and controls did not differ with respect to general cognitive abilities and sex but children with UCP were significantly older. Controls performed significantly better than children with UCP on neuromotor tasks at all levels of motor integration. Additionally, performance of the non-plegine hand in children with UCP was significantly inferior to controls. With the exception of fine motor skills (pyramidal level), children with right and left UCP did not differ. Our behavioral neuromotor examination was sensitive to reveal impairments at all three levels of motor integration bilaterally in children with UCP-although more subtle for the non-paretic limb.

Relação entre função motora e cognitiva na paralisia cerebral hemiplégica / Relationship between motor and cognitive function in hemiplegic cerebral palsy

Introdução: Crianças com paralisia cerebral hemiplégica (PCH) exibem dificuldades funcionais na utilização do membro superior hemiparético, repercutindo negativamente no desempenho em realizar atividades de vida diária. Atualmente, os déficits motores nessa população são acompanhados por distúrbios sensoriais, dificuldades na aprendizagem, alterações de comportamento e comunicação e défices cognitivos gerais. Objetivo: Investigar a possível associação entre os déficits motores e cognitivos de crianças com PCH, verificando ainda a influência da lateralidade da hemiplegia. Métodos: Participaram do estudo 30 crianças com PCH (idade média = 10,48 ± 2,46 anos). Os participantes foram submetidos aos seguintes testes: Assisting Hand Assessment (AHA), Matrizes Progressivas Coloridas de Raven, o Subteste cubos do Wechsler Intelligence Scale for Children fourth Edition - WISC IV e a fluência verbal semântica de animais. Resultados: Os grupos foram homogêneos em relação ao sexo e idade (p > 0.05). Os grupos não diferiram em relação ao nível de desempenho motor, memória de trabalho, inteligência e fluência verbal (p > 0,05). O desempenho motor correlacionou com todas as variáveis cognitivas. Conclusão: Em crianças com PCH o desempenho motor correlacionou fortemente com funções cognitivas. Além disso, a lateralidade da lesão cerebral não influenciou o desempenho em tarefas motoras e cognitivas. (AU)

Introduction: Children with hemiplegic cerebral palsy (HCP) exhibit functional difficulties in using the hemiparetic upper limb, negatively impacting their performance in carrying out activities of daily living. Currently, motor deficits in this population are accompanied by sensory disorders, learning difficulties, changes in behavior and communication and general cognitive deficits. Objective: To investigate the possible association between motor and cognitive deficits in children with PCH, also verifying the influence of laterality in hemiplegia. Methods: Thirty children with PCH participated in the study (mean age = 10.48 ± 2.46 years). Participants were subjected to the following tests: Assisting Hand Assessment (AHA), Raven's Colorful Progressive Matrices, the Wechsler Intelligence Scale for Children fourth Edition - WISC IV Subtest and the semantic verbal fluency of animals. Results: The groups were homogeneous in relation to sex and age (p > 0.05). The groups did not differ in relation to the level of motor performance, working memory, intelligence and verbal fluency (p> 0.05). Motor performance correlated with all cognitive variables. Conclusion: In children with PCH, motor performance correlated strongly with cognitive functions. In addition, the laterality of the brain injury did not influence performance in motor and cognitive tasks. (AU)

Motor Imagery Development in Children: Changes in Speed and Accuracy With Increasing Age.

Although motor imagery has been pointed as a promising strategy for the rehabilitation of children with neurological disorders, information on their development throughout childhood and adolescence is still scarce. For instance, it is still unclear at what age they reach a development comparable to the motor imagery performance observed in adults. Herein we used a mental rotation task to assess motor imagery in 164 typically developing children and adolescents, which were divided into four age groups (6-7, 8-9, 10-11, and 12-13 years) and 30 adults. The effects of biomechanical constraints, accuracy, and reaction time of the mental rotation task were considered. ANOVA showed that all groups had the effect of biomechanical restrictions of the mental rotation task. We found a group effect for accuracy [F (4, 180) = 17,560; p < 0.00; η2 = 3.79] and reaction time [F (4, 180) = 17.5; p < 0.001, η2 = 0.615], with the results of children groups 6-7 and 8-9 years being significantly lower than the other groups (p < 0.05). In all the analyses, there were no differences regarding accuracy and reaction time among the participants of the age groups 10-11 and 12-13 years and adults (p > 0.05). Concluding, children aged 6-7 years were able to perform motor imagery, motor imagery ability improved as the participants' ages increased, and children aged 10 and over-performed similarly to adults.

Reabilitação dos membros inferiores na paralisia cerebral diplégica / Rehabilitation of lower limbs in diplegic cerebral palsy

A paralisia cerebral (PC) é uma das causas mais comuns de incapacidade motora na infância. Resulta de uma perturbação não progressiva no cérebro imaturo. A diplégica espástica (DE) é a forma mais comum de PC e cursa com deficiência nos membros inferiores e no padrão de marcha. Tal limitação tem impacto negativo no desempenho da criança para realizar tarefas básicas de vida diária. O presente estudo objetivou revisar a literatura científica acerca das principais técnicas utilizadas para reabilitar os membros inferiores de crianças com DE. A pesquisa bibliográfica foi realizada nas bases de dados Lilacs, Scielo, Pubmed e incluiu artigos publicados, entre 2010 e 2018, em inglês e português. Após aplicar os critérios de inclusão e exclusão, um total de 28 estudos foi selecionado para a revisão. As principais técnicas encontradas no tratamento da DE foram: método Pilates, Equoterapia, Esteira, Hidroterapia, Therasuit, Bobath, Estimulação Elétrica Funcional e Realidade Virtual. Todos os estudos encontraram efeitos positivos. Os resultados revelaram que o uso isolado de uma das técnicas não é tão eficaz quanto o uso concomitante de duas ou mais delas. A maioria dos estudos revisados são estudos de caso. Novos estudos controlados e com amostras maiores ainda são necessários. (AU)

Cerebral palsy (CP) is one of the most common causes of motor incapacity in childhood. It results from a non-progressive disorder in the immature brain. Spastic diplegia (SD) is the most common form of CP with deficits in the lower limbs and walking pattern. Such a limitation has a negative impact on the child's performance to perform basic tasks of daily living. The present study aimed to review the scientific literature about the main techniques used to rehabilitate the lower limbs of children with SD. This review was carried out in Lilacs, Scielo, Pubmed and included articles published between 2010 and 2018, in English and Portuguese. After applying the inclusion and exclusion criteria, 28 studies were selected. The main techniques found in the treatment of SD were Pilates, Equine Therapy, Treadmill, Hydrotherapy, Therasuit, Bobath, Functional Electrical Stimulation and Virtual Reality. All studies found positive effects. The results revealed that the isolated use of one of the techniques is not as effective as the concomitant use of two or more of them. Most of the studies reviewed are case studies. New controlled studies and larger samples are still needed. (AU)

Effect of motor imagery combined with physical practice on upper limb rehabilitation in children with hemiplegic cerebral palsy.

INTRODUCTION: Evidence indicates that motor deficits in hemiplegic cerebral palsy (HCP) impair both motor execution and planning. However, current rehabilitation efforts focus mainly on relieving impairments in motor execution. Motor imagery (MI) is a promising method for stimulating neural networks underlying the planning and control of movements. OBJECTIVE: Evaluate the effectiveness of MI combined with physical practice in improving the function of the upper limbs in children with HCP. METHOD: Twenty-four participants, aged 7-14 years were divided into two groups: intervention group (IG) and control group (CG). The IG was subjected to MI training and physical practice twice a week for eight consecutive weeks, while the CG received conventional therapy. Participants were assessed with the Assisting Hand Assessment (AHA) at pre-intervention, post-intervention, and follow up. RESULTS: The results showed improved motor functions in both groups. Analysis using the general linear model (analysis of covariance) and Bonferroni post hoc tests showed significant improvements from pre-intervention to post-intervention in the AHA for the IG. The CG showed non-significant improvement in AHA scores. CONCLUSIONS: These findings suggest that the MI training, combined with the physical practice program used in this study, was effective in improving upper limb function in children with HCP.

Body representation in children with hemiplegic cerebral palsy.

Clinical observations indicate that many children with hemiplegic cerebral palsy refrain from using or disregard the affected upper limb. The aim of the present study is to investigate deficits in different body representations (body schema, body structural description, and body image) in children with hemiplegic cerebral palsy (HCP) compared to typically-developing (TD) children. Three groups of children participated in this study: 42 TD children (aged 5.17-10.91 years), 23 children with right HCP (aged 5.83-10.92 years), and 22 children with left HCP (aged 5.67-10.90 years). The results demonstrate generalized deficits in all three body representations in children with HCP, and do not offer evidence for an effect of hemiplegia laterality.
