RESUMEN
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.
RESUMEN
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.

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.
RESUMEN
Cognitive impairment is frequent in cerebral palsy (CP) and there is a lack of multiprofessional screening instruments. OBJECTIVE: The aim of this study was to investigate the utility of the Mini-Mental State Examination for Children (MMC), an adapted version of the Mini-Mental State Examination, in screening for cognitive impairments in children with CP. METHODS: We assessed 397 Brazilian children, 310 with typical development and 87 with CP (hemiplegic and quadriplegic forms), aged 5-16 years. Association between the MMC and general intelligence was assessed by the Colored Progressive Matrices instrument. RESULTS: Psychometric indexes for the MMC were adequate. ROC analyses revealed effective diagnostic accuracy in all ages assessed. Cut-off values are reported. Major difficulties on the MMC were observed in children with CP, particularly individuals with the quadriplegic form. Moreover, the MMC showed moderate correlation with the intelligence test, and was reliable in discriminating, among clinical cases, those with poorer cognitive abilities. CONCLUSION: The MMC could be useful as a multiprofessional screening instrument for cognitive impairment in children with hemiplegic CP. Results of the MMC in quadriplegic CP children should be interpreted with caution. Diagnosis should be confirmed by further psychological testing.

As análises ROC revelaram eficácia diagnóstica para todas as idades avaliadas. Os valores de corte são relatados. Dificuldades importantes na MMC foram observadas em crianças com PC, principalmente em crianças tetraplégicas. Além disso, MMC mostrou correlação moderada com o teste de inteligência e boa precisão na identificação das crianças com PC que possuem habilidades cognitivas prejudicadas. CONCLUSÃO: O MMC poderia ser útil como um instrumento de triagem multiprofissional para comprometimento cognitivo em crianças hemiplégicas. Os resultados de MMC em crianças tetraplégicas devem ser interpretados cuidadosamente. O diagnóstico deve ser confirmado por mais testes psicológicos.

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.

Crianças pré-termo podem apresentar distúrbios leves do desenvolvimento motor, que podem ser imperceptíveis até a idade pré-escolar ou escolar. O objetivo desse estudo foi comparar o desenvolvimento motor de crianças pré-termo moderadas com crianças a termo aos sete e oito anos de idade. Foram coletados dados de 13 crianças pré-termo e 13 crianças a termo de uma escola da rede municipal de Betim. Foi utilizada a Escala de Desenvolvimento Motor para avaliar motricidade fina, motricidade global, equilíbrio, esquema corporal, organização espacial e organização temporal, bem como a idade motora geral e o quociente motor geral. O teste Mann-Whitney foi utilizado para comparar as idades motoras e os quocientes motores entre os grupos. Foi encontrada diferença significativa somente nos valores da motricidade fina entre os grupos (p=0,01), sendo que o grupo pré-termo apresentou desempenho inferior. Dessa forma, crianças pré-termo moderadas que não apresentam características de alto risco biológico ao nascimento também podem necessitar de acompanhamento ambulatorial até a idade escolar.
Preterm children may have light motor developmental impairments, which may be imperceptible until pre-school age or even school age. The aim of this study was to compare the motor development of moderate preterm children with full-term ones at seven and eight years of age. Data from 13 preterm and 13 full-term children were collected from a public school in Betim-MG. The Motor Development Scale was used to access fine and global motricity, balance, body scheme, spatial organization, time organization, as well as general motor age and general motor quotient. The Mann-Whitney's Test was used to compare the motor ages and motor quotients between the groups. A significant difference was only found in the fine motricity values between the groups (p=0.01), the preterm group having shown a poorer performance. Therefore, moderate preterm children who do not have highly risky biological characteristics at birth may also need outpatient assistance up to school age.

Crianças com diplegia espástica apresentam um padrão de marcha caracterizado pela posição do tornozelo em flexão plantar, flexão excessiva do joelho associado ao valgismo e aumento da adução e rotação interna do quadril. A postura em flexão plantar do tornozelo, secundária á espasticidade, é um dos principais fatores que interferem na função plantar da marcha. Foi realizado um relato de caso para descrever e avaliar a atuação fisioterap~eutica associada à aplicação da toxina botulínica tipo A (Dysport) nos flexores plantares de uma criança com diplegia espática. A criança foi avaliada pré-aplicação da toxina botulínica, 30 e 60 dias após a sua aplicação pelo Sistema de Classificação da Função Motora Grossa (GMFCS), da Medida da Função Motora Grossa (GMFM), da goniometria do tornozelo e do Vídeo Gait Analysis (VGA). O programa de fisioterapia iniciou-se no dia seguinte à aplicação. Foi verificada mudança de um nível no GMFCS com melhora de 15º com o joelho fletido e 17º com joelho estendido e no tornozelo esquerdo uma melhora de 3º e 10º, respectivamente. No VGA ocorreu alteração de um grau no tornozelo esquerdo. Isso demonstra que um programa de fisioterapia associado à aplicação da toxina botulínica interferiu positivamente no desempemho da funcionallidade de uma criança com diplegia espástica e encustamento dos flexores plantares
Children with spastic diplegia presents a gait pattern characterized by the position of the ankle in plantar flexion, excessive knee flexion associated with valgus alignment and increased adduction and internal rotation of the hip. The plantar flexion position of the ankle, secondary to the spasticity, is one of the main factors that impairs gait function. A case report was carried out to describe and to evaluate a physical therapy program associated to the application of botulinum toxin type A (Dysport) in plantar flexors of one child with spastic diplegia. The child was evaluated daily before, 30 and 60 days after the application of the botulinum toxin by Gross Motor Function Classification System (GMFCS), Gross Motor Function Measure (GMFM), ankle goniometry and Video Gait Analysis (VGA). The physical therapy program was initiated in the day following to application. A level change in GMFCS was verified accompanied by a improvement of 9,4% in the GMFM score. Right ankle range of motion showed a 15º improvement when assessed with knee joint in flexion and 17º when assessed with knee joint in extension, in the left ankle, improvements of 3º and 10º were checked, respectively. VGA revealed a one degree change in the left ankle. This demonstrates that association of the physical therapy program with botulinum toxin application showed a positive effect in functional outcomes in a child with spastic diplegia and plantar flexors muscle shortening.
