Catquest-9SF questionnaire: validation of the Portuguese version using the Rasch analysis.

PURPOSE: The aim of this study was to validate the Portuguese version of Catquest-9SF through its application in a native Brazilian population with cataracts and to determine the correlation of the questionnaire scores with preoperative visual acuity. METHODS: A prospective study was conducted to validate the Catquest-9SF questionnaire, which was translated and back-translated, generating a final version in Portuguese. A total of 120 Brazilian patients awaiting cataract surgery were recruited to answer the questionnaire and to document their preoperative data and visual acuity. The Rasch analysis was used to assess the instrument's psychometric properties. RESULTS: The Portuguese version of Catquest-9SF demonstrated an acceptable adjustment of the items (item fit statistics ranging from 0.7 to 1.3), unidimensionality (principal component analysis), and good organization in the item response categories (thresholds of the categories: -2.79, 0.57, and 2.22, respectively). The questionnaire contains items with stable relationships if considered at the same level of visual impairment in the comparison between the two groups (absence of differential item functioning). The separation of people (person separation index, 3.07) was adequate. The visual acuity in the logarithm of the minimum angle of resolution (logMAR) in the best eye with the best optical correction showed a statistically significant correlation with the Catquest-9SF logit score (r=0.282 and p=0.004). CONCLUSIONS: The Portuguese version of Catquest-9SF presents evidence of validity and reliability, in addition to being linguistically and culturally understandable for Portuguese-speaking patients born in Brazil. The questionnaire is easy to understand and quick to apply, as it could adequately estimate the subjective visual functioning in patients with cataracts. We found a significant correlation between visual acuity and the questionnaire score.

Can tactile reactivity in preterm born infants be explained by an immature cortical response to tactile stimulation in the first year? A pilot study.

This study aimed to compare preterm (PT) and full-term (FT) infants' adaptive behavior and functional cortical response to tactile stimulus, as measured by Test of Sensory Functions in Infants and functional Near-Infrared Spectroscopy (fNIRS). Outcome measures were taken at 6 (PT = 26/FT = 21 infants) and 12 months (PT = 15/FT = 14 infants). At 6 months, poorer tactile reactivity was observed in PT, but not confirmed at 12 months. At 6 months, cortical response to tactile stimulus was found in the primary sensorimotor cortex and differences between groups did not reach significance. At 12 months, cortical response was found in the primary sensorimotor cortex and premotor area and in the somatosensory associative area, with significant less frequent response in premotor area in PT. The findings reinforce fNIRS as a tool to complement the knowledge of tactile adaptive behaviors in PT in early life.

Cognitive assessment in preterms by Bayley-III: development in the first year and associated factors.

OBJECTIVE: To analyze the cognitive development of preterm infants at six and 12 months of corrected age and the associations with perinatal and socioeconomic factors. METHODS: Cognitive development of 40 infants (20 preterm and 20 full-term) at six and 12 months of age was evaluated using the Bayley-III scale. Correlations between cognitive outcome and associated factors were assessed using Spearman correlation. Stepwise multiple linear regression analysis with covariance was applied to identify changes on cognitive score between six and 12 months. RESULTS: Bayley-III cognitive score in preterm group was significantly lower than in full-term group at both six and 12 months of age. Birth weight correlated with cognitive performance at six months and head circumference at birth at 12 months, in full-terms infants. The occurrence of necrotizing enterocolitis was inversely associated with cognitive score in preterms at 12 months. An increase in cognitive score was observed between six and 12 months in both groups, but the gain was more pronounced in preterms. CONCLUSIONS: These findings suggest some cognitive recovery capacity in the first year despite the restrictions imposed by premature birth and emphasize the importance of early interventions in this population.

Survey of Well-Being of Young Children (SWYC): Preliminary Norms for Screening for Developmental Delay in Brazilian Children Younger than 65 Months.

OBJECTIVE: The objective of this study was to investigate the reliability and validity of the Developmental Milestones Questionnaire of the Survey of Wellbeing of Young Children Brazilian version (DM-SWYC-BR) and establish the preliminary norms to identify suspected developmental delay in Brazilian children up to 65 months. METHODS: A psychometric study was conducted on 1535 children from 3 Brazilian regions. The caregivers answered the Brazilian Portuguese cross-culturally adapted version of the DM-SWYC. We calculated the internal consistency and performed an exploratory factor analysis (EFA). The clinical threshold for the suspected developmental delay was set at 85% from the DM-SWYC-BR mean score for each age. The prevalence of suspected delay was calculated using current preliminary cutoffs and original norms. RESULTS: EFA confirmed the unidimensionality of the DM-SWYC-BR items (average variance extracted = 0.78). Cronbach's alpha was 0.97. At most ages, the difference between the cutoff points in the Brazilian and North American samples was lower than or equal to 2 points, except at 18, 23, 29, 44, 45, 46, and from 54 to 58 months. There was a marked divergence in the prevalence of suspected developmental delay by age ranges using the Brazilian or North American cutoff points. However, the general mean prevalence was quite similar (27.5% vs. 28.2%, respectively). CONCLUSIONS: We established the cutoff points to interpret the DM-SWYC-BR results when screening for developmental delays in Brazilian children. The satisfactory psychometric properties support its use for screening developmental delays in the public health system. Reliable assessment tools are critical to promoting child development effectively, ensuring timely intervention.

[Cross-cultural adaptation and analysis of the psychometric properties of the Brazilian version of the Motor Activity Log]. / Adaptação transcultural e análise das propriedades psicométricas da versão brasileira do instrumento Motor Activity Log.

OBJECTIVE: To describe the translation into Brazilian Portuguese and cross-cultural adaptation of the Motor Activity Log (MAL), an instrument specifically designed to assess function of the more severely affected upper limb in hemiplegics. METHODS: The MAL was translated and adapted according to standardized procedures and submitted to test-retest reliability assessment (intraclass correlation coefficient, ICC). Other psychometric properties were investigated using Rasch analysis in 77 chronic hemiplegics (41 men, mean age = 57.5 ± 12.4 years). RESULTS: An excellent ICC (0.98) was obtained for the total scores of both the quantity and quality MAL scales. When assessing degree of difficulty, "using a key to unlock the door" was the most difficult item on the quantity scale, whereas "washing hands" was the easiest one. On the quality scale, the most difficult item was "using the TV remote control," and the easiest one was "drying hands." The analyses showed that the set of items as a whole fit into the model; however, the individual analyses indicated that four items did not meet the expectations of the model in both the quantity (items 21, 16, 14, and 13) and quality (items 9, 21, 23, and 22) scales. Irregular response patterns were observed, and five subjects obtained the minimum score. There was disagreement between item difficulty and sample ability, suggesting that the abilities of individuals were below the degree of difficulty of the assessed items. A significant correlation was observed between grip strength of the more severely affected upper limb and motor skill measurement among individuals on the quantity (r = 0.51, P < 0.0001) and quality scales (r = 0.57, P < 0.0001), and also between the two scales when measuring the individuals' motor skills (r = 0.97, P < 0.0001). CONCLUSIONS: MAL-Brazil is potentially useful to evaluate the more severely affected upper limb in Brazilian patients with chronic hemiplegia. However, the instrument has limitations for use with individuals with severe limb impairments. Also, construct validity was affected by the presence of irregular score patterns. MAL-Brazil should be applied to additional samples to further investigate its validity.

Efficacy of CO-OP Approach With and Without Parental Coaching: RCT Study Protocol: Efficacité de l'approche CO-OP avec et sans coaching parental : protocole d'essai clinique randomisé.

BACKGROUND.: Developmental coordination disorder (DCD) leads to decreased occupational performance and restricted participation. Cognitive Orientation to daily Occupational Performance Approach (CO-OP) is effective, and as parental support is a key element, it seems relevant to investigate. PURPOSE.: To describe a study protocol that will compare CO-OP with and without Occupational Performance Coaching (OPC) on activity and participation of children with DCD. METHOD.: Randomized controlled with seven to 12-year-olds, assigned to either experimental (CO-OP+OPC) or control (CO-OP) group, both receiving traditional CO-OP, with four additional parental group sessions for the experimental group. KEY ISSUES.: Actual and perceived occupational performance and satisfaction of children's chosen goals and participation, motor performance and executive function. Measures will be obtained at baseline, post-intervention, and at 3-month follow-up. IMPLICATIONS.: Detailed description of an intervention protocol may help further replication and may contribute to clarify if a boost on parents' participation promotes better outcomes for children with DCD. TRIAL REGISTRATION.: Clinical Trials, NCT02893852. (https://clinicaltrials.gov/ct2/show/NCT02893852).

Brazilian versions of the Measure of Processes of Care-20 and Measure of Processes of Care-Service Providers: translation, cross-cultural adaptation and reliability.

BACKGROUND: The Measure of Processes of Care (MPOC) questionnaires evaluate Family-Centered Practice (FCP) in services for children with developmental disorders. The MPOC-20 and MPOC-SP are completed by parents and by rehabilitation professionals, respectively, and are widely used in several countries. OBJECTIVES: To translate and cross-culturally adapt the MPOC-20 and MPOC-SP to Brazilian Portuguese and evaluate their reliability and internal consistency. METHODS: this study included translation, back-translation, cognitive interviews, testing of the pre-final versions, analysis of reliability and of internal consistency of the final versions. Respondents included parents and rehabilitation professionals from rehabilitation centers in four capital cities in Brazil. RESULTS: Translation and cultural-adaptation procedures ensured the Brazilian versions were understandable and semantically equivalent to the original MPOC-20 and MPOC-SP. Pre-final and final versions were analyzed and vetted by the original authors. The MPOC-20 internal consistency Cronbach's alpha varied between 0.61 and 0.91 (n=107), the test-retest reliability ICC varied between 0.44 and 0.83 and the standard error of measurement varied between 0.66 and 0.85 (n=50). The MPOC-SP internal consistency Cronbach's alpha varied between 0.52 and 0.83 (n=92), the test-retest reliability ICC between 0.83 and 0.90, and the standard error of measure between 0.34 and 0.46 (n=62). CONCLUSION: The Brazilian versions of the MPOC-20 and the MPOC-SP are in general stable and sufficiently reliable. They are relevant to the evaluation of FCP and provide information that can improve health services and ensure better care.

Effects of early interventions focused on the family in the development of children born preterm and/or at social risk: a meta-analysis.

OBJECTIVE: To verify whether early intervention focused on the family improves the cognitive, motor, and language development of children born preterm and/or at social risk in the first 3 years of life. SOURCE OF DATA: Meta-analysis of clinical trials published between 2008 and 2018, in the following databases: CINAHL, MEDLINE - PubMed, MEDLINE - BVS, LILACS - BVS, IBECS - BVS, PEDro and Cochrane Reviews. Experimental studies on early interventions focused on the family, whose target groups were children born preterm and/or at social risk, with assessment of cognitive and/or motor and/or language development up to 3 years were included. The studies were rated using the PEDro Scale. DATA SYNTHESIS: Twelve studies were included from a total of 3378 articles. Early intervention focused on the family contributed to the development of the cognitive (Standardized Mean Difference - SMD=0.48, 95% CI: 0.34-0.61) and motor (SMD=0.76, 95% CI: 0.55-0.96) domains of preterm infants. Regarding cognitive development, performance improvement was observed at 12, 24 and 36 months, while in the motor domain, the effect was observed only at 12 months in preterm infants. There was no benefit of the intervention in the cognitive, motor, and language outcomes of children with the social risk factor associated to biological risk. CONCLUSION: Early intervention focused on the family has a positive effect on the cognition of preterm infants. The effect on motor development was lower, possibly due to the emphasis on interventions in family-child interaction. The effect of interventions on the development of children at social risk and on the language domain was inconclusive, due to the scarcity of studies in the area.

Bilateral coordination and motor sequencing in Brazilian children: preliminary construct validity and reliability analysis.

This study examined aspects of reliability and validity of the bilateral coordination and motor sequencing items of the Assessment of Motor Coordination and Dexterity (AMCD) for Brazilian children ages 4, 6 and 8 years old. The AMCD aims to identify children with developmental coordination disorder (DCD). A total of 84 children were evaluated. Among the 35 items piloted, all but one presented interrater reliability above 0.80 and 16 (45.7%) items presented intraclass correlation coefficient over 0.60 for test-retest reliability. Most items were sensitive to age difference and only items involving ball handling exhibited significant gender differences. As a result, this section of the AMCD could be reduced to the 20 items that were found to be reliable and more discriminative for age-related differences. This study advances on the development of the AMCD, but a limitation was the noninclusion of children with DCD. Future research should investigate whether the selected items are useful in differentiating the motor skills of children with and without coordination problems.

Efficacy of the cognitive orientation to daily occupational performance with Brazilian children with developmental coordination disorder.

BACKGROUND: Children with Developmental Coordination Disorder (DCD) have difficulties performing daily activities which reflects negatively on participation, impacting their lives. OBJECTIVES: To examine the effects of the cognitive orientation to daily occupational performance Approach (CO-OP Approach) protocol on occupational performance and satisfaction of Brazilian children who have DCD; to examine whether children could transfer strategies and skills learned during CO-OP to untrained goals. METHODS: A pre-post group comparison design with eight boys aged 6-10 years old. Children participated in 12 CO-OP sessions with their parents twice a week, with an extra session added to the protocol for parents´ orientation. The Canadian Occupational Performance Measure and the Performance Quality Rating Scale were used as outcome measures. The study was registered by the United States Institutes of Health at ClinicalTrials.gov (NCT03112746). RESULTS: Intervention resulted in higher, clinically and statistically significant, occupational performance measures according to parents, children's, and external evaluators' perspectives. All children improved occupational performance on their selected goals and five children could transfer the ability to use cognitive strategies to tasks not addressed in therapy. CONCLUSIONS: This study provides initial directions for future research to investigate the applicability and to implement CO-OP approach on pediatric settings in Brazil.

Percepção de cuidadores de pré-escolares com TEA sobre seu comportamento e desempenho ocupacional durante a pandemia da COVID-19 / Perception of caregivers of preschool children with ASD on their behavior and occupational performance during the COVID-19 pandemic

Resumo Introdução Crianças com Transtorno do Espectro Autista (TEA) podem apresentar questões comportamentais, no processamento sensorial, na cognição e na linguagem, que afetam seu desempenho ocupacional, necessitando de acesso a serviços escolares, terapêuticos e de saúde. O acesso a esses serviços esteve restrito durante a pandemia de COVID-19, tornando essa população particularmente ainda mais vulnerável às restrições sociais impostas à época. Objetivo Descrever a percepção dos pais cuidadores de pré-escolares com TEA acerca do comportamento e desempenho ocupacional de seus filhos durante a pandemia da COVID-19. Método Estudo transversal, descritivo, quantitativo e qualitativo baseado em entrevistas com 60 cuidadores de pré-escolares com TEA. Os participantes responderam à seguinte pergunta: Você está notando alguma diferença no comportamento e desempenho da criança durante a pandemia? Para caracterização das crianças, foram utilizados o Sistema de Classificação de Funcionalidade no Autismo: Comunicação Social (ACSF:SC), o Inventário de Avaliação Pediátrica de Incapacidade - Teste Adaptativo de Computador (PEDI-CAT) e o Perfil Sensorial 2 (SP-2). Todas as entrevistas foram anotadas e 15 delas foram gravadas e transcritas. O material foi submetido à análise temática de conteúdo. Resultados Foram entrevistadas 43 mães, 15 casais e dois pais de crianças com TEA. Das 60 crianças, 46 (76,7%) eram meninos, com idade de 3 a 5 anos (53,6 ±10,18 meses). Os cuidadores perceberam mudanças no comportamento e desempenho ocupacional, com prevalência de relatos de piora. Houve aumento nas estereotipias, rigidez e hiperfoco, bem como menor engajamento nas atividades cotidianas. A presença dos cuidadores beneficiou algumas crianças, mas há relato de estresse, especialmente por parte das mães. Conclusão Houve variação nos relatos, com maior tendência à piora no comportamento e desempenho ocupacional das crianças com TEA.

Abstract Introduction Children with Autism Spectrum Disorder (ASD) face behavioral, sensory processing, cognitive, and language challenges that affect their ability to perform activities of daily living (ADL) and necessitate access to educational, therapeutic, and health services. The COVID-19 pandemic limited access to these essential services, exacerbating the challenges faced by this vulnerable population due to imposed social distancing measures. Objective To explore the perceptions of parent caregivers of preschoolers with ASD regarding their children's behavior and performance in ADL during the COVID-19 pandemic. Method This cross-sectional, descriptive study utilized both quantitative and qualitative approaches, interviewing 60 caregivers of preschoolers with ASD. Participants were asked about any observed changes in their child's behavior and ability to engage in ADL during the pandemic. Child characterization involved the Autism Classification System of Functioning: Social Communication (ACSF:SC), the Pediatric Evaluation of Disability Inventory - Computer Adaptive Test (PEDI-CAT), and the Sensory Profile 2 (SP-2). Interviews were documented, with 15 recorded and transcribed for thematic content analysis. Results Participants included 43 mothers, 15 couples, and two fathers, totaling 60 children, of whom 46 (76.7%) were boys aged between 3 and 5 years (mean age 53.6 ±10.18 months). Caregivers reported changes in behavior and performance in ADL, predominantly noting deterioration. Increases in stereotypic behaviors, rigidity, and hyperfocus were observed, along with decreased participation in ADL. While the presence of caregivers benefited some children, it also led to reported stress, particularly among mothers. Conclusion The study found a predominant trend of deteriorating behavior and performance in ADL among children with ASD during the pandemic, based on caregiver reports.

Cognitive assessment in preterms by Bayley-III: development in the first year and associated factors / Avaliação cognitiva em crianças pré-termo usando Bayley-III: desenvolvimento no primeiro ano de vida e fatores associados

ABSTRACT Objective: To analyze the cognitive development of preterm infants at six and 12 months of corrected age and the associations with perinatal and socioeconomic factors. Methods: Cognitive development of 40 infants (20 preterm and 20 full-term) at six and 12 months of age was evaluated using the Bayley-III scale. Correlations between cognitive outcome and associated factors were assessed using Spearman correlation. Stepwise multiple linear regression analysis with covariance was applied to identify changes on cognitive score between six and 12 months. Results: Bayley-III cognitive score in preterm group was significantly lower than in full-term group at both six and 12 months of age. Birth weight correlated with cognitive performance at six months and head circumference at birth at 12 months, in full-terms infants. The occurrence of necrotizing enterocolitis was inversely associated with cognitive score in preterms at 12 months. An increase in cognitive score was observed between six and 12 months in both groups, but the gain was more pronounced in preterms. Conclusions: These findings suggest some cognitive recovery capacity in the first year despite the restrictions imposed by premature birth and emphasize the importance of early interventions in this population.

RESUMO Objetivo: Avaliar o desenvolvimento cognitivo de crianças pré-termo aos seis e 12 meses de idade corrigida e as associações com fatores perinatais e socioeconômicos. Métodos: O desenvolvimento cognitivo de 40 crianças (20 pré-termo e 20 a termo) foi avaliado aos seis e 12 meses de idade, utilizando a escala Bayley-III. Correlações entre resultados cognitivos e fatores associados foram avaliadas pelo teste de correlação de Spearman. A análise de regressão linear múltipla stepwise com covariância foi aplicada para identificar mudanças na pontuação cognitiva entre seis e 12 meses. Resultados: O escore cognitivo no grupo pré-termo foi significativamente menor que no grupo a termo aos seis e 12 meses. O peso ao nascer foi diretamente associado com o desempenho cognitivo aos seis meses e perímetro cefálico ao nascimento aos 12 meses, nas crianças a termo. A ocorrência de enterocolite necrosante foi inversamente associada ao desempenho cognitivo em pré-termos, aos 12 meses. Verificou-se aumento na pontuação cognitiva entre seis e 12 meses nos dois grupos, porém mais pronunciado no pré-termo. Conclusões: O estudo sugere que crianças pré-termo apresentam alguma capacidade de recuperação cognitiva no primeiro ano, apesar das restrições impostas pelo nascimento prematuro, e enfatizam a importância de acompanhamento dessa população desde os primeiros meses de vida.

OBSERVATION OF NEONATAL BEHAVIOR: CROSS-CULTURAL ADAPTATION OF THE NEWBORN BEHAVIORAL OBSERVATIONS. / OBSERVAÇÃO DO COMPORTAMENTO NEONATAL: ADAPTAÇÃO TRANSCULTURAL DO NEWBORN BEHAVIORAL OBSERVATIONS.

OBJECTIVE: To conduct the cross-cultural adaptation for Brazilian Portuguese of the Newborn Behavioral Observations (NBO), a new resource for observing neonatal behavior and sharing information with parents. METHODS: Methodological study of translation and cultural adaptation of the NBO system, which includes the Recording Form, with 18 items, the Recording Guidelines, with instructions to score each item, the Summary Form, to record suggestions based on the observation, and the Parent Questionnaire, to record the parents' experiences. The adaptation process followed international recommendations for cross-cultural adaptation of health care protocols, which included requesting permission from the authors, translation, back translation and pre-test, followed by external evaluators who scored the quality of the adaptation, which was analyzed quantitatively. The quality of the adaptation of the instruments' items was evaluated by the index of agreement between evaluators for conceptual and cultural equivalence. RESULTS: Expert panel evaluation showed that the cross-cultural adaptation of the NBO protocols was both well understood conceptually and culturally appropriate, with 140 (77.8%) items presenting concordance index higher than 90% for conceptual and cultural equivalence. Items that did not reach adequate level of agreement were revised according to experts' suggestions. CONCLUSIONS: The Brazilian version of the NBO system can be safely used, since the methodology was rigorous enough to ensure equivalence between the original and translated versions. The NBO should be tried in clinical practice, as it can contribute to improve the quality of maternal and child care.

Foram seguidas as recomendações internacionais para adaptação transcultural de protocolos da área de saúde, o que incluiu solicitação de autorização para tradução aos autores, tradução, retrotradução e pré-teste, seguido de avaliação externa por painel de especialistas, que avaliou a qualidade da adaptação de cada item, com cálculo do índice de concordância entre os avaliadores quanto à equivalência conceitual e cultural. RESULTADOS: A avaliação do painel de especialistas evidenciou que a versão adaptada transculturalmente do sistema NBO foi bem compreendida conceitualmente e adequada culturalmente, com 140 (77,8%) itens apresentando índice de concordância maior que 90% quanto à equivalência conceitual e cultural. Itens que não obtiveram níveis adequados de concordância foram revisados conforme sugestões dos especialistas. CONCLUSÕES: A versão brasileira do sistema NBO pode ser utilizada com segurança, já que a metodologia empregada foi rigorosa, garantindo equivalência entre o original e a tradução. O sistema NBO está pronto para ser usado clinicamente, podendo contribuir para a melhora de qualidade da assistência materno-infantil.

Clinical application of the Newborn Behavioral Observation (NBO) System to characterize the behavioral pattern of newborns at biological and social risk.

OBJECTIVE: To compare the behavior of preterm newborns and full-term newborns using the Newborn Behavioral Observation and to evaluate the mothers' experience when participating in this observation. METHOD: This was a cross-sectional study performed at a referral hospital for high-risk births, involving mothers and neonates before hospital discharge. The mothers answered the sociodemographic questionnaire, participated in the Newborn Behavioral Observation session, and evaluated the experience by answering the parents' questionnaire at the end. The characteristics of the preterm newborn and full-term newborn groups and the autonomic, motor, organization of states, and responsiveness scores were compared. Linear regression was performed to test the association of the characteristics of mothers and neonates with the scores in the autonomic, motor, organization of states, and responsiveness domains. RESULTS: The Newborn Behavioral Observation was performed with 170 newborns (eight twins and 77% preterm newborns). Approximately 15% of the mothers were adolescents and had nine years of schooling, on average. The groups differed regarding weight for gestational age, age at observation, APGAR score, feeding, and primiparity. The linear regression adjusted for these variables showed that only prematurity remained associated with differences in the scores of the motor (p=0.002) and responsiveness (p=0.02) domains. No statistical difference was observed between the groups in the score attributed to one's own knowledge prior to the session (p=0.10). After the session, these means increased in both groups. This increase was significantly higher in the preterm newborn group (p=0.02). CONCLUSIONS: The Newborn Behavioral Observation increased the mothers' knowledge about the behavior of their children, especially in mothers of preterm newborns, and identified differences in the behavior of preterm newborns and full-term newborns regarding the motor and responsiveness domains.

Terapia motora cognitiva: descrição e análise clínica de crianças com Transtorno do Desenvolvimento da Coordenação (TDC), / Cognitive motor therapy: description and clinical analysis of children with Developmental Coordination Disorder (DCD)

Resumo Introdução Estima-se que 6% das crianças em idade escolar apresentam Transtorno do Desenvolvimento da Coordenação (TDC), caracterizado por dificuldades motoras que restringem a participação em casa, na comunidade e na escola. A Cognitive Orientation to Daily Occupational Performance Approach (CO-OP) é efetiva para melhorar o desempenho funcional dessas crianças, mas há poucos dados clínicos sobre variações na resposta à intervenção. Objetivo Identificar e descrever as características mais relevantes de crianças com TDC que influenciam sua resposta à CO-OP. Método Estudo de caso conduzido com quatro crianças com TDC submetidas à CO-OP: as duas que obtiveram maior e menor ganho com a intervenção. Os dados obtidos no estudo foram categorizados e sintetizados para compor uma descrição clínica das características dos participantes. Resultados Os pais das crianças com melhor desempenho apresentaram melhor estilo parental. A observação não estruturada das pesquisadoras durante as coletas identificou que as famílias das crianças com maior progresso compareceram mais vezes às coletas e eram mais engajadas. Maior apoio familiar parece proporcionar mais confiança às crianças, além de aumentar a motivação para alcançar os objetivos em terapia. Conclusão O apoio oferecido pelos pais é fator relevante para o bom desempenho de crianças com TDC na intervenção usando a CO-OP. A descrição clínica de crianças com TDC auxilia o raciocínio durante a prática profissional por identificar características que podem influenciar o progresso na intervenção.

Abstract Introduction It is estimated that 6% of school-age children have Developmental Coordination Disorder (DCD), characterized by motor difficulties that restrict participation at home, in the community and at school. The Cognitive Orientation to Daily Occupational Performance Approach (CO-OP) is effective in improving the functional performance of these children, but there is little clinical data on variations in the response to the intervention. Objective To identify and describe the most relevant characteristics of children with DCD that influence their response to CO-OP. Method Case study conducted with four children with DCD who underwent CO-OP: the two who had the highest gain and the two who had the lowest gain with the intervention. The data obtained in this study were categorized and synthesized to compose a clinical description of the participants' characteristics. Results Parents of children with better performance showed better parenting style. Unstructured observation of the researchers during the collections showed that the families of the children with greater progress attended the collections more often and were more engaged. Greater family support seems to provide children with more confidence, as well as increase motivation to achieve goals in therapy. Conclusion The support offered by parents is a relevant factor for the good performance of children with DCD in the intervention using the CO-OP. The clinical description of children with DCD assists in the reasoning during professional practice because it identifies characteristics that can influence progress in the intervention.

Catquest-9SF questionnaire: validation of the Portuguese version using the Rasch analysis / Questionário Catquest-9SF: validação da versão em português utilizando análise Rasch

ABSTRACT Purpose: The aim of this study was to validate the Portuguese version of Catquest-9SF through its application in a native Brazilian population with cataracts and to determine the correlation of the questionnaire scores with preoperative visual acuity. Methods: A prospective study was conducted to validate the Catquest-9SF questionnaire, which was translated and back-translated, generating a final version in Portuguese. A total of 120 Brazilian patients awaiting cataract surgery were recruited to answer the questionnaire and to document their preoperative data and visual acuity. The Rasch analysis was used to assess the instrument's psychometric properties. Results: The Portuguese version of Catquest-9SF demonstrated an acceptable adjustment of the items (item fit statistics ranging from 0.7 to 1.3), unidimensionality (principal component analysis), and good organization in the item response categories (thresholds of the categories: -2.79, 0.57, and 2.22, respectively). The questionnaire contains items with stable relationships if considered at the same level of visual impairment in the comparison between the two groups (absence of differential item functioning). The separation of people (person separation index, 3.07) was adequate. The visual acuity in the logarithm of the minimum angle of resolution (logMAR) in the best eye with the best optical correction showed a statistically significant correlation with the Catquest-9SF logit score (r=0.282 and p=0.004). Conclusions: The Portuguese version of Catquest-9SF presents evidence of validity and reliability, in addition to being linguistically and culturally understandable for Portuguese-speaking patients born in Brazil. The questionnaire is easy to understand and quick to apply, as it could adequately estimate the subjective visual functioning in patients with cataracts. We found a significant correlation between visual acuity and the questionnaire score.

Existe correlação significativa com a acuidade visual e a pontuação obtida no questionário.

Association between hemodynamic activity and motor performance in six-month-old full-term and preterm infants: a functional near-infrared spectroscopy study.

This study aimed to assess task-induced activation in motor cortex and its association with motor performance in full-term and preterm born infants at six months old. A cross-sectional study of 73 six-month-old infants was conducted (35 full-term and 38 preterm infants). Motor performance was assessed using the Bayley Scales of Infant Development third edition-Bayley-III. Brain hemodynamic activity during motor task was measured by functional near-infrared spectroscopy (fNIRS). Motor performance was similar in full-term and preterm infants. However, differences in hemodynamic response were identified. Full terms showed a more homogeneous unilateral and contralateral activated area, whereas in preterm-born the activation response was predominantly bilateral. The full-term group also exhibited a shorter latency for the hemodynamic response than the preterm group. Hemodynamic activity in the left sensorimotor region was positively associated with motor performance measured by Bayley-III. The results highlight the adequacy of fNIRS to assess differences in task-induced activation in sensorimotor cortex between groups. The association between motor performance and the hemodynamic activity require further investigation and suggest that fNIRS can become a suitable auxiliary tool to investigate aspects of neural basis on early development of motor abilities.

SENSORY PROCESSING DURING CHILDHOOD IN PRETERM INFANTS: A SYSTEMATIC REVIEW. / PROCESSAMENTO SENSORIAL NO PERÍODO DA INFÂNCIA EM CRIANÇAS NASCIDAS PRÉ-TERMO: REVISÃO SISTEMÁTICA.

OBJECTIVE: To conduct a systematic search for grounded and quality evidence of sensory processing in preterm infants during childhood. DATA SOURCE: The search of the available literature on the theme was held in the following electronic databases: Medical Literature Analysis and Retrieval System Online (Medline)/PubMed, Latin American and Caribbean Literature in Health Sciences (Lilacs)/Virtual Library in Health (BVS), Índice Bibliográfico Español de Ciencias de la Salud (IBECS)/BVS, Scopus, and Web of Science. We included only original indexed studies with a quantitative approach, which were available in full text on digital media, published in Portuguese, English, or Spanish between 2005 and 2015, involving children aged 0-9years. DATA SYNTHESIS: 581 articles were identified and eight were included. Six studies (75%) found high frequency of dysfunction in sensory processing in preterm infants. The association of sensory processing with developmental outcomes was observed in three studies (37.5%). The association of sensory processing with neonatal characteristics was observed in five studies (62.5%), and the sensory processing results are often associated with gestational age, male gender, and white matter lesions. CONCLUSIONS: The current literature suggests that preterm birth affects the sensory processing, negatively. Gestational age, male gender, and white matter lesions appear as risk factors for sensoryprocessing disorders in preterm infants. The impairment in the ability to receivesensory inputs, to integrateand to adapt to them seems to have a negative effect on motor, cognitive, and language development of these children. We highlight the feasibility of identifying sensory processing disorders early in life, favoring early clinical interventions.

OBJETIVO: Buscar sistematicamente evidências fundamentadas e de qualidade sobre o processamento sensorial em crianças nascidas pré-termo no período da infância. FONTES DE DADOS: A busca da literatura disponível sobre o tema foi realizada nas bases de dados eletrônicas Sistema Online de Busca e Análise de Literatura Médica (Medline)/PubMed, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs)/Biblioteca Virtual em Saúde (BVS), Índice Bibliográfico Español de Ciencias de la Salud (IBECS)/BVS, Scopus e Web of Science. Foram incluídos estudos indexados, originais, quantitativos e disponíveis na íntegra em meio digital, publicados em português, inglês ou espanhol, entre 2005 e 2015, envolvendo crianças entre zero e 9 anos de idade. SÍNTESE DOS DADOS: A busca identificou 581 artigos, e oito foram incluídos conforme critérios de elegibilidade. Destes, seis estudos (75%) encontraram alta frequência de processamento sensorial alterado em crianças pré-termo. A associação entre processamento sensorial e desfechos de desenvolvimento foi observada em três estudos (37,5%). Verificou-se associação entre processamento sensorial e características neonatais em cinco estudos (62,5%). Os resultados de processamento sensorial frequentemente se associam a idade gestacional, sexo masculino e lesões da substância branca. CONCLUSÕES: Análise da literatura atual sugere que prematuridade tem impacto negativo no processamento sensorial. Idade gestacional, sexo masculino e lesões de substância branca aparecem como fatores de risco para alterações de processamento sensorial em crianças nascidas pré-termo. O prejuízo na capacidade de receber informações sensoriais, de integrar e de adaptar-se a elas parece interferir negativamente no desenvolvimento motor, cognitivo e de linguagem dessas crianças. Destaca-se a viabilidade da identificação das alterações de processamento sensorial nos primeiros anos de vida, favorecendo o encaminhamento precoce para intervenções clínicas.

[Cross-cultural adaptation and analysis of the psychometric properties in the Brazilian version of the Human Activity Profile]. / Adaptação transcultural e análise das propriedades psicométricas da versão brasileira do Perfil de Atividade Humana.

The aim of the present study was to evaluate the psychometric properties in the Brazilian version of the Human Activity Profile (HAP), an instrument for the assessment of daily functions and level of physical activity. The HAP was translated into Portuguese following the recommended methodology and applied to 230 community-dwelling elderly (66.32 +/- 8.5 years) from the city of Belo Horizonte, Minas Gerais State, Brazil. The data were submitted to Rasch analysis, which detected very easy and difficult items, making it possible to employ the instrument with both frail and highly functional individuals. The separation index of 3.1 indicated that the items divided the individuals into three levels of functional ability. Of the 94 HAP items, six (6.38%) did not fit the statistical model, which jeopardized its construct validity, since the items did not fit into a continuum. Therefore, caution should be taken when employing the HAP to individuals having similar characteristics. If HAP is applied to different samples and the proportion of erratic items is still more than 5%, modification, substitution, or exclusion of those items is suggested to guarantee that HAP measures a unidimensional construct.
