Is screening for motor skill deficits in Tyrolean preschool children warranted and feasible? A protocol for a two-stage cross-sectional study.

INTRODUCTION: Children with developmental coordination disorder (DCD) show deviations in motor development and motor skills in early childhood where the learning and execution of coordinated motor skills are below the level expected for their age. Early detection of DCD is critical to provide an opportunity for intervention and support, yet many cases remain undetected until school age. The study described aims to determine the warranty, feasibility and validity of a mobility screening in Tyrolean kindergartens and evaluate its potential benefit to enhance the motor development prospects of affected children. METHODS AND ANALYSIS: This research employs a two-stage cross-sectional approach with 6 months of follow-up assessments. The initial stage involves a playful mobility screening for all participating kindergarten children, followed by individual assessments for those displaying conspicuous motor skills. Motor skills will be evaluated using MobiScreen 4-6 and the Movement Assessment Battery for Children-2. Prior to the screening, informed consent is obtained from kindergarten bodies and authorities, parents and the children themselves. Parents are provided with information sheets and questionnaires to assess their attitudes and their child's eligibility. The study described aims to form a representative sample of kindergarten children, aged 4-6, in Tyrol. To target approximately 20-40 children with DCD for follow-up, the goal is to include 650 children, assuming an incidence of 3%-6%. For the follow-up, matching control groups will be formed and information about how identified motor deficits were addressed, including therapies or sports, will be gathered. Quantitative data will mainly be analysed descriptively, while feedback from kindergarten teachers regarding the practical implementation will be analysed using qualitative content analyses, according to Mayring. ETHICS AND DISSEMINATION: The study has been approved by the Research Committee for Scientific Ethical Questions (RCSEQ 3369/24). Findings will be disseminated through contributions, peer-reviewed journals, and conferences.

Predictive validity of the Developmental Coordination Disorder Questionnaire as a screening tool to identify motor skill problems: A systematic review and meta-analysis.

BACKGROUND: The Developmental Coordination Disorder Questionnaire (DCDQ) has been used to screen children who probably have developmental coordination disorder (DCD). AIMS: We systematically reviewed studies on the predictive validity of the DCDQ and performed a meta-analysis on its diagnostic accuracy. METHODS AND PROCEDURES: Literature was searched through four electronic databases: MEDLINE, Embase, CINAHL, and PsycArticles. A total of 27 studies was selected based on the inclusion criteria. The sensitivity and specificity of the DCDQ were assessed using summary receiver operating characteristic (sROC) curves. Subgroup analyses were conducted according to the DCDQ type, reference standard, and participant type. OUTCOMES AND RESULTS: Overall, the DCDQ has a sensitivity of 0.70 and a specificity of 0.77, showing moderate diagnostic accuracy (area under the curve, 0.80). Subgroup analysis showed that the revised version of the DCDQ had higher diagnostic accuracy than the original version. When the reference standard was the Diagnostic and Statistical Manual of Mental Disorders, the sensitivity and specificity of the DCDQ were 0.87 and 0.83, respectively. The diagnostic accuracy was higher in clinical samples compared to the general population. CONCLUSIONS AND IMPLICATIONS: This study demonstrated that the DCDQ has adequate diagnostic accuracy, suggesting it can help screen children with motor skill deficits.

Criterion Validity and Applicability of Motor Screening Instruments in Children Aged 5-6 Years: A Systematic Review.

The detection of motor developmental problems, especially developmental coordination disorder, at age 5-6 contributes to early interventions. Here, we summarize evidence on (1) criterion validity of screening instruments for motor developmental problems at age 5-6, and (2) their applicability. We systematically searched seven databases for studies assessing criterion validity of these screening instruments using the M-ABC as reference standard. We applied COSMIN criteria for systematic reviews of screening instruments to describe the correlation between the tests and the M-ABC. We extracted information on correlation coefficients or area under the receiver operating curve, sensitivity and specificity, and applicability in practice. We included eleven studies, assessing eight instruments: three performance-based tests (MAND, MOT 4-6, BFMT) and five questionnaires (DCD-Q, PQ, ASQ-3, MOQ-T-FI, M-ABC-2-C). The quality of seven studies was fair, one was good, and three were excellent. Seven studies reported low correlation coefficients or AUC (<0.70), four did not report these. Sensitivities ranged from 21-87% and specificities from 50-96%, with the MOT4-6 having the highest sensitivity and specificity. The DCD-Q, PQ, ASQ-3, MOQ-T-FI, and M-ABC-2-C scored highest on applicability. In conclusion, none of the instruments were sufficiently valid for motor screening at age 5-6. More research is needed on screening instruments of motor delay at age 5-6.

Impact of New Motor Deficit on HRQOL After Adult Spinal Deformity Surgery: Subanalysis From Scoli Risk 1 Prospective Study.

STUDY DESIGN: International, multicenter, prospective, longitudinal observational cohort. OBJECTIVE: To assess how new motor deficits affect patient reported quality of life scores after adult deformity surgery. SUMMARY OF BACKGROUND DATA: Adult spinal deformity surgery is associated with high morbidity, including risk of new postoperative motor deficit. It is unclear what effect new motor deficit has on Health-related Quality of Life scores (HRQOL) scores. METHODS: Adult spinal deformity patients were enrolled prospectively at 15 sites worldwide. Other inclusion criteria included major Cobb more than 80°, C7-L2 curve apex, and any patient undergoing three column osteotomy. American Spinal Injury Association (ASIA) scores and standard HRQOL scores were recorded pre-op, 6 weeks, 6 months, and 2 years. RESULTS: Two hundred seventy two complex adult spinal deformity (ASD) patients enrolled. HRQOL scores were worse for patients with lower extremity motor score (LEMS). Mean HRQOL changes at 6 weeks and 2 years compared with pre-op for patients with motor worsening were: ODI (+12.4 at 6 weeks and -4.7 at 2 years), SF-36v2 physical (-4.5 at 6 weeks and +2.3 at 2 years), SRS-22r (0.0 at 6 weeks and +0.4 at 2 years). Mean HRQOL changes for motor-neutral patients were: ODI (+0.6 at 6 weeks and -12.1 at 2 years), SF-36v2 physical (-1.6 at 6 weeks and +5.9 at 2 years), and SRS-22r (+0.4 at 6 weeks and +0.7 at 2 years). For patients with LEMS improvement, mean HRQOL changes were: ODI (-0.6 at 6 weeks and -16.3 at 2 years), SF-36v2 physical (+1.0 at 6 weeks and +7.0 at 2 years), and SRS-22r (+0.5 at 6 weeks and +0.9 at 2 years). CONCLUSION: In the subgroup of deformity patients who developed a new motor deficit, total HRQOLs and HRQOL changes were negatively impacted. Patients with more than 2 points of LEMS worsening had the worst changes, but still showed overall HRQOL improvement at 6 months and 2 years compared with pre-op baseline.Level of Evidence: 3.

Investigating fine motor deficits during maintenance therapy in children with acute lymphoblastic leukemia.

OBJECTIVES: Children diagnosed with acute lymphoblastic leukemia (ALL) in their early childhood are more susceptible to neuromuscular and musculoskeletal impairments. This cross-sectional study was designed to address different types of fine motor impairments in Egyptian children diagnosed with ALL. METHODS: Fifty-four children treated for ALL in maintenance phase aged from four to seven years were compared with an age- and sex-matched control group. Fine motor performance was assessed using the total fine motor form of the Bruininks-Oseretsky Test of Motor Proficiency-second edition (BOT-2). Sex- and age-specific norms of BOT-2 were used to calculate scale and standard scores in both groups. RESULTS: Children with ALL had significantly impaired fine motor skills in all subtests and composites of BOT-2 compared with the typically developing group (P < 0.00001). Cumulative doses of vincristine, methotrexate, and dexamethasone revealed no significant correlation with any BOT-2 measure. Males performed significantly better than females in all BOT-2 scores except for the fine motor integration subtest and the total fine motor control composite as no significant differences were observed. The protocol risk stratum, duration of maintenance treatment, and the age at assessment did not significantly affect the BOT-2 measures. CONCLUSION: About 67% of children with ALL on maintenance treatment experienced fine motor difficulties. Periodic evaluation along the course of chemotherapy could identify specific impaired fine motor domains providing the base for a successful rehabilitation program.

Are boys and girls just different? Gender differences in the Movement Assessment Battery for Children, 2nd edition (M ABC-2) suggests that they are.

INTRODUCTION: The second edition of the Movement Assessment Battery for Children (M ABC-2) is a standardised, norm referenced assessment that is frequently used by therapists to identify children with motor difficulties. The norms for the M ABC-2 were derived from a sample of children in the United Kingdom (UK) and are combined across the age groups for boys and girls. The aims of this research were to investigate gender differences in the performance of 8- and 9-year-old Australian children and if the norms in our cohort differed from UK-based M ABC-2 norms. METHODS: Children aged 8 or 9 years of age who underwent major neonatal cardiac or non-cardiac surgery and healthy controls were assessed using the M ABC-2 as part of the Development After Infant Surgery (DAISy) study. RESULTS: There were statistically significant differences in the scores for boys and girls aged 8- and 9-years old on the M ABC-2. Girls performed better than boys in manual dexterity and on total standard scores. Our control group compared to the assessment norms scored significantly poorer in manual dexterity, aiming and catching and total standard scores. CONCLUSION: Caution should be used when interpreting the results of the M ABC-2 for Australian 8- and 9-year olds. Contemporary Australian, gender-specific M ABC-2 norms should be considered. Further research is required to investigate gender differences and differences in performance of Australian children compared to the assessment norms in other age groups on the M ABC-2.

ABSTRACT This study aimed to translate and adapt the Clinical Utility Scale of Tyson and Connell into Brazilian Portuguese, in addition to evaluating intra- and inter-rater reliability. The process of cross-cultural translation and adaptation was developed in five stages: translation, synthesis of translations, retro translation, evaluation by the committee of experts and testing of the pre-final version. To evaluate the intra- and inter-rater reliability of the Clinical Utility Scale of Tyson and Connell, 20 assessment instruments were independently assessed by two examiners (inter-rater reliability). In addition, one of the examiners performed all assessments at two different times with a 30-day interval (intra-rater reliability). The translation and cross-cultural adaptation were performed in a systematic way, following the proposed criteria, and only minor changes in two items were necessary to make the scale more useful to all instruments currently available in the literature. Regarding the inter-rater reliability of the Clinical Utility Scale of Tyson and Connell, the value found was ICC=0.85 (IC 95%, 0,79-0,87), while for intra-rater reliability the result was ICC=0,89 (IC 95%, 0,85-0,93). The results of this process indicated an adequate degree of semantic, conceptual and cultural equivalence. In addition, intra- and inter-rater reliability measures were considered adequate. These findings have shown the scale is adequate to assess the clinical utility of evaluation instruments usually applied to patients. Therefore, it must be incorporated into clinical practice and research when choosing the best evaluation instrument to be used.

ABSTRACT Congenital heart defects (CHD) are among the main causes of morbidity and mortality in infants who has this impairment may present delays in neuropsychomotor development (NPMD). This study assesses the influence of CHD on NPMD of infants. This is an observational study assessing neuropsychomotor development performed by Bayley Scales of Infant and Toddler Development - BSID-III. The Brazilian Economic Classification Criteria was used to verify the socioeconomic status of the families and also the maternal and infants' clinical conditions were verified in the medical discharge report and in the child's health handbook. For the association between the quantitative and qualitative variables with the NPMD, the Spearman's correlation coefficient and the likelihood ratio test were used. A total of 18 infants were assessed, with a predominance of females (72.2%). Most mothers (47.1%) had complete high school or incomplete higher education, with a mean age of 27.2±5.5 years. There was a correlation between the BSID-III scales and the quantitative variables analyzed: motor scale with weight (p=0.02 and r=0.54) and oxygen therapy (p=0.009 and r=−0.591); besides that, the qualitative variables correlation were: motor scale and socioeconomic condition (p=0.015), motor scale and Interatrial Communication - IAC (p=0.023) and language with IAC scales (p=0.038). CHD influences the delay of NPMD, mainly for motor aspect. Furthermore, weight, diagnosis of IAC, use of oxygen therapy and socioeconomic status were considered the main risk factors for the delay in NPMD.

Ktk motor test: review of the main influencing variables / Teste motor ktk: revisão das principais variáveis influenciadoras

ABSTRACT Objective: To analyze the scientific literature regarding the effects of external variables on KTK motor test scores and to verify which motor tests are associated with KTK. Data sources: Four databases (PubMed, Science Direct, Scientific Electronic Library Online - SciELO - and Latin American and Caribbean Health Sciences Literature - LILACS) were used to search for studies in which the descriptors Körperkoordinationstest für Kinder and KTK were presented in the title, abstract and keywords. Inclusion criteria were: articles published in English or Portuguese from January 2006 to December 2016; free access to the article in full and texts available online; presenting the descriptor terms mentioned above in the title, abstract or keywords; containing sample with children and adolescents aged 4 to 16 years old; being indexed in a journal with a rating of B2 or higher (WebQualis; Qualis 2016) for the area of physical education. The following were excluded: studies in books, chapters of books, theses and dissertations; duplicate scientific articles; conference summaries; articles published in proceedings and abstracts of congresses. Data synthesis: After the three stages of selection (identification, screening and eligibility) and the criteria proposed at the PICOS scale, 29 studies were included in this review. Conclusions: Body composition and the regular practice of physical activities were the variables that presented the greatest influence on KTK. It is important that health professionals working with the pediatric public encourage regular physical activity to improve body composition and, thus, to obtain better KTK scores. Additionally, the Movement Assessment Battery for Children (M-ABC) test had the highest positive correlation with the KTK test.

Molecular and Histopathological Characterization of Patients Presenting with the Duchenne Muscular Dystrophy Phenotype in a Tertiary Care Center in Southern India.

OBJECTIVE: To study the histopathological characteristics and mutation spectrum of patients presenting with the Duchenne muscular dystrophy (DMD) phenotype. METHODS: This was a descriptive study conducted over a period of 8 years. Multiplex ligation-dependent probe amplification (MLPA) was done in patients presenting with the DMD phenotype. If MLPA was negative, patients were offered muscle biopsy for histopathological studies and/or next generation sequencing (NGS) based multigene panel testing for muscular dystrophies. RESULTS: Of the 510 patients included, mutation in the DMD gene was detected by MLPA in 372 (72.9%), of whom 342 (67.1%) had exonic deletions and 30 (5.9%) had exonic duplications. Exons 45-55 were most commonly involved in large deletions and exons 1-10 were the commonest exons involved in duplications. In the MLPA-negative cohort, 27 proceeded for muscle biopsy. NGS was done in 14 patients, 10 of whom had pathogenic mutations in the DMD gene, 3 were non dystrophinopathies and no pathogenic variant could be identified in one patient. CONCLUSIONS: For patients presenting with the DMD phenotype, MLPA of the DMD gene has a high diagnostic rate of about 73%, and non-dystrophinopathies may constitute a small but significant proportion.

A School-Based Screening Tool for Adolescents With Low Motor Coordination Abilities.

This study sought to select the most relevant test items from the Bruininks-Oseretsky Test of Motor Proficiency, Second Edition (BOTMP-2) and from a selection of health-related fitness tests for identifying school teenagers with poor motor coordination. The 241 participants in this study (144 boys, 97 girls aged 13-14 years old) were tested on the short form of the BOTMP-2 and on the following additional fitness tests: (a) seated medicine ball test, (b) broad jump, (c) handgrip strength, (d) alternate hand ball wall toss, (e) 10 × 5-meter agility shuttle run, and (f) Chester step test. We performed a factor analysis of participant scores on these various tasks and BOTMP-2 test items to reduce them to the least number of meaningful and useful items. Four factors explained 45% of the data variance: gross motor skills and power (including broad jump, hand ball toss, shuttle run, and sit-ups tests); fine motor skills (including copying star, following the maze and paper folding); core strength and balance (including push-ups, hopping, and balance beam); and general body strength (including medicine ball throw and handgrip). We conclude that an efficient school-based battery of test items to screen 13-14 year old adolescents for fitness and coordination should assess these four factors and might especially rely upon the broad jump, copying a star shape, hopping handgrip strength, aerobic fitness, and wall ball toss.

Fall risk in stroke survivors: Effects of stroke plus dementia and reduced motor functional capacity.

BACKGROUND: Despite extensive research on falls among individuals with stroke, little is known regarding the impact of neurological conditions with comorbid diagnoses and motor functional capacity on the risk of falls in these individuals. Hence, the purpose of this study was to determine the fall risk and the contribution of reduced motor functional capacity to fall risk in individuals with stroke, dementia, and stroke plus dementia. METHODS: Data from the National Health and Aging Trends Study (NHATS), a nationally-representative sample of Medicare beneficiaries, were analyzed for this cross-sectional study. The odds of self-reported falls within the past month in three subgroups of neurological conditions [stroke (n = 751), dementia (n = 369), and stroke plus dementia (n = 141)] were evaluated with a reference group of individuals with no stroke/dementia [i.e., controls (n = 6337)] using logistic regression models. RESULTS: The prevalence of a recent fall was significantly higher (P < .05) in the three neurological disorder groups compared with controls. After adjusting for sociodemographics, mobility device use, and other comorbidities (i.e., chronic disease, vision impairment, and major surgery), the odds of a recent fall were significantly elevated in individuals with stroke (odds ratio [OR] = 1.45), dementia (OR = 2.45), and stroke plus dementia (OR = 2.64) compared with controls. After further adjustment for the lower motor functional capacity, the elevated odds in individuals with stroke were attenuated (OR = 1.16); however, the odds remained significantly elevated in individuals with dementia (OR = 1.67) and stroke plus dementia (OR = 1.82). CONCLUSION: Findings indicate that the odds for falls in stroke survivors are elevated in the presence of comorbid dementia. Further, lower motor functional capacity accounted for increased likelihood of a fall in individuals with stroke, but it was not sufficient to account for the increased likelihood of a fall in individuals with dementia or stroke plus dementia. Thus, interventions focusing on secondary prevention of dementia and improving motor functional capacity may reduce fall risk in individuals with stroke.

Is the motor skills checklist appropriate for assessing children in Japan?

PURPOSE: Motor skill screening tools are essential for the early detection of developmental coordination disorder (DCD). The present study aimed to examine any cultural and rater effects on these tools. This then enabled us to judge the validity of the original cut-off values for identifying diagnosable children. METHODS: A community sample survey was performed in Japan; 3852 children aged 6-9 years were recruited. Both parents and teachers evaluated the motor skills of their children using the Movement Assessment Battery for Children - Second Edition Checklist. The psychometric properties were evaluated and the scoring characteristics examined based on the type of rater and country of origin, as compared to data originally sampled in the UK. RESULTS: High reliability and validity of the Japanese samples were confirmed. The Japanese adults evaluated their children's motor skills more rigorously than the Europeans. Additionally, there was a large disagreement between parent and teacher rating scores; the degree of agreement varied depending on the severity of motor deficits in the child. CONCLUSION: The first findings from a Japanese sample suggest that the assessment of motor skills in children is significantly affected by culture and rater. These cultural characteristics and rater biases strongly suggest that new cut-off values, reflecting country and rater type, be introduced for identifying children at risk of DCD.

Structural validity of the Bruininks-Oseretsky test of motor proficiency - Second edition brief form (BOT-2-BF).

BACKGROUND: Practitioners often assess the motor skills of children presented with suspected developmental delays. It is essential that the tests used to assess children have strong measurement properties including validity. AIM: The structural validity of the Bruininks-Oseretsky Test of Motor Proficiency - second edition Brief Form (BOT-2-BF) was investigated. METHOD: 123 healthy children (67 males & 56 females; M = 10 years, 2 months; SD = 1 year, 4 months) completed the BOT-2-BF. The Rasch Measurement Model (RMM) was used to assess the 14-item BOT-2-BF's dimensionality, hierarchical ordering, differential item functioning (DIF), and item and person separation reliability. RESULTS: Nine BOT-2-BF misfit RMM requirements. A second RMM analysis of a five-item BOT-2-BF version was completed. The five-item version did meet the RMM requirements of item fit, dimensionality, hierarchical ordering, lack of DIF, and adequate item and person separation reliability. IMPLICATIONS: The 14-item version of the BOT-2-BF is not recommended for use as a screening scale to assess children's motor skill performance. However, a revised five-item version of the BOT-2-BF did appear to meet RMM expectations. Further psychometric assessment of the revised five-item version of the BOT-2-BF is recommended.

A new motor screening assessment for children at risk for motor disorders: construct validity.

OBJECTIVE: To develop a motor screening assessment and provide preliminary evidence of its psychometric properties. METHODS: A sample of 365 elementary school students was assessed, with structural equation modeling applied to obtain evidence of the adequacy of the factor structure of the motor screening assessment. As well, differential item functioning was used to evaluate whether various identifiable subgroups of children (i.e., sex and grade) perform particular tasks differently. RESULTS: Overall, girls obtained higher scores than boys while, for both sexes, the assessment scores increased with age. Furthermore, differential item function analysis revealed that the precision of the test was highest for those with moderate to low motor performance, suggesting that this tool would be appropriate for identifying individuals with movement difficulties. CONCLUSION: Although further tests of its psychometric properties are required, the motor screening assessment appears to be a reliable, valid, and quickly-administered tool for screening children's movements.

RESUMO Objetivo: Desenvolver uma avaliação de triagem motora (ATM) e fornecer evidências preliminares de suas propriedades psicométricas. Métodos: 365 alunos do ensino fundamental foram avaliados. Foi utilizado modelagem de equações estruturais para evidenciar a adequação da estrutura fatorial da ATM. A função diferencial do item foi utilizada para avaliar tarefas podem funcionar de forma diferente para subgrupos (ou seja, sexo e escolaridade). Resultados: Em geral, as meninas obtiveram pontuações mais altas do que os meninos e, em ambos os sexos, os escores da avaliação aumentaram com a idade. A análise da função diferencial do item revelou que a precisão do teste foi maior para aqueles com desempenho motor baixo a moderado, sugerindo que essa ferramenta seria apropriada para identificar aqueles com dificuldades motoras. Conclusão: Embora sejam necessários novos testes de suas propriedades psicométricas, a ATM parece ser uma ferramenta confiável, válida e rápida de administrar como rastreio motor para crianças.

Motor development of preterm infants assessed by the Alberta Infant Motor Scale: systematic review article / Desenvolvimento motor de prematuros avaliados pela Alberta Infant Motor Scale: artigo de revisão sistemática

Abstract Objective: Premature newborns are considered at risk for motor development deficits, leading to the need for monitoring in early life. The aim of this study was to systematically review the literature about gross motor development of preterm infants, assessed by the Alberta Infant Motor Scale (AIMS) to identify the main outcomes in development. Data source: Systematic review of studies published from 2006 to 2015, indexed in Pubmed, Scielo, Lilacs, and Medline databases in English and Portuguese. The search strategy included the keywords: Alberta Infant Motor Scale, prematurity, preterm, motor development, postural control, and follow-up. Data summary: A total of 101 articles were identified and 23 were selected, according to the inclusion criteria. The ages of the children assessed in the studies varied, including the first 6 months up to 15 or 18 months of corrected age. The percentage variation in motor delay was identified in the motor outcome descriptions of ten studies, ranging from 4% to 53%, depending on the age when the infant was assessed. The studies show significant differences in the motor development of preterm and full-term infants, with a description of lower gross scores in the AIMS results of preterm infants. Conclusions: It is essential that the follow-up services of at-risk infants have assessment strategies and monitoring of gross motor development of preterm infants; AIMS is an assessment tool indicated to identify atypical motor development in this population.

Resumo Objetivo: Recém-nascidos prematuros são considerados de risco para déficits no desenvolvimento motor, o que ocasiona a necessidade de acompanhamento nos primeiros anos de vida. O objetivo do presente estudo é revisar de forma sistemática as publicações que abordam o desenvolvimento motor amplo de crianças nascidas prematuras, avaliadas por meio da Alberta Infant Motor Scale (AIMS), de modo a apontar os principais desfechos motores. Fontes dos dados: Revisão sistemática das publicações de 2006 a 2015, indexadas nas bases de dados Pubmed, Scielo, Lilacs e Medline, nos idiomas inglês e português. A estratégia de busca incluiu palavras-chaves: prematuro, pré-termo, prematuridade, desenvolvimento motor, controle postural, seguimento, Alberta Infant Motor Scale, prematurity, pre-term, motor development, postural control e follow-up. Síntese dos dados: Foram identificados 101 artigos e selecionados 23, conforme critérios de inclusão. As idades das crianças avaliadas nos estudos incluíram os primeiros seis meses até os 15 ou 18 meses de idade corrigida. Variado percentual de atraso motor foi identificado na descrição dos desfechos motores de 10 estudos, de 4 a 53%, dependeu da idade em que o bebê foi avaliado. Os estudos apontam diferenças significativas no desenvolvimento motor de prematuros e crianças nascidas a termo, com descrição de escores brutos mais baixos nos resultados da AIMS de crianças prematuras. Conclusões: É fundamental que os serviços de seguimento de bebês de risco apresentem estratégias de avaliação e acompanhamento do desenvolvimento motor amplo de prematuros, a AIMS é uma ferramenta de avaliação indicada para identificar comportamentos motores atípicos nessa população.

Value of pre-cue information for motor tasks performed by children with developmental coordination disorder (DCD)

People commonly use pre-cue information to advance and reduce the information processing time required for a motor task (e.g., motor planning). However, children with developmental coordination disorder (DCD) exhibit difficulties performing pre-cued goal-directed tasks. The purpose of the present study was to investigate the use of valid, neutral, and invalid pre-cue information for a goal-directed task. The participants were 11 children with DCD (mean age = 7.94 yrs.) and 11 typically developed (TD) age- and gender-matched children. The children with DCD exhibited delayed motor planning (e.g., reaction time) under the invalid condition compared to that of the TD children. The children with DCD used atypical strategies for motor execution and depended more on online corrections (e.g., increased deceleration time and movement units) to reach the target. These results suggest that children with DCD have difficulties handling unpredictable situations and that the use of atypical motor execution strategies did not affect movement time

Validity of the Ages and Stages Questionnaire to detect risk of Developmental Coordination Disorder in preschoolers.

BACKGROUND: A reliable and valid screening tool for detecting children at risk for Developmental Coordination Disorder (DCD) is needed. The purpose of this study was to evaluate the ability of the Ages and Stages Questionnaire-Third Edition (ASQ-3) motor scales to detect children at risk for DCD in a community-based sample of children aged 3.5-5.5 years. METHODS: One hundred and sixty parent-child pairs were recruited from community-based organizations. Children were eligible if they spoke English and had no known physical impairments. Eligible parents were asked to fill out the ASQ-3, following which their child's fine motor and gross motor proficiency was assessed using the Movement Assessment Battery for Children-Second Edition (MABC-2). DCD risk was defined as those children scoring at or below the 16th percentile on the MABC-2. Sensitivity and specificity of the fine and gross motor areas of the ASQ-3 were examined and referenced against the DCD risk classification. RESULTS: The ASQ-3 total motor score correlated moderately with overall standard score on the MABC-2 (r = 0.41; p < 0.001). Regardless of the ASQ-3 cut-off used, sensitivities of the ASQ-3 fine motor or gross motor scale to detect DCD risk were low at 21-47%, whereas specificities were high at 89-96%. CONCLUSION: Early identification of motor skill delays is important in order to intervene and hopefully prevent the associated negative health consequences. However, because of the low sensitivity of the ASQ-3 motor scales, these results suggest that the ASQ-3 is not an appropriate screening tool to identify children at risk for DCD in the preschool population.
