Cumulative Prenatal Risk Factors and Developmental Coordination Disorder in Young Children.

To examine the effect of cumulative prenatal risk factors (RFs) on the presence of Developmental Coordination Disorder (DCD) in young children. Participants (N = 589, 338 boys, Mage = 4.5 ± 0.5years) were from a larger cohort study, the Coordination and Activity Tracking in Children (CATCH). Motor coordination was assessed using the Movement Assessment Battery for Children- 2nd Edition. Children were classified as at risk for DCD (DCDr) based on European Academy of Childhood Disability guidelines. RFs were obtained through a parent-completed survey. A multiple logistic regression was conducted to examine the effect of the RFs on DCD. Results showed that the odds of a child having DCDr are significantly higher with a greater total number of prenatal RFs, after adjustment for mother's age at child's birth, child's sex, child's age, marital status and total annual household income (OR = 1.48, p < 0.01). These findings warrant further investigation into the cumulative impact of multiple prenatal RFs and whether specific combinations of RFs might be more strongly linked to DCD than others. These results provide additional insight into possible causes and prevention of DCD.

Evaluation of the Developmental Coordination Questionnaire (DCDQ) as a Screening Instrument for Co-occurring Motor Problems in Children with Autism Spectrum Disorder.

Although motor problems are highly prevalent in children with autism spectrum disorder (ASD), they remain underdiagnosed. Questionnaire-based screening for motor problems could optimize current clinical practice. This study aimed to examine the psychometric properties of the developmental coordination disorder questionnaire (DCDQ) to screen for co-occurring motor problems in individuals with ASD (n = 115; aged 5-15years). Results indicated an excellent internal consistency; concurrent and discriminant validity with the Movement Assessment Battery for Children, second edition. Sensitivity was excellent, but specificity was lower. The positive and negative predictive values indicate that the DCDQ can be used to detect motor problems in children with ASD and can exclude the presence of developmental coordination disorder.

Intrinsic Cortico-Subcortical Functional Connectivity in Developmental Dyslexia and Developmental Coordination Disorder.

Developmental dyslexia (DD) and developmental coordination disorder (DCD) are distinct diagnostic disorders. However, they also frequently co-occur and may share a common etiology. It was proposed conceptually a neural network framework that explains differences and commonalities between DD and DCD through impairments of distinct or intertwined cortico-subcortical connectivity pathways. The present study addressed this issue by exploring intrinsic cortico-striatal and cortico-cerebellar functional connectivity in a large (n = 136) resting-state fMRI cohort study of 8–12-year-old children with typical development and with DD and/or DCD. We delineated a set of cortico-subcortical functional circuits believed to be associated with the brain’s main functions (visual, somatomotor, dorsal attention, ventral attention, limbic, frontoparietal control, and default-mode). Next, we assessed, using general linear and multiple kernel models, whether and which circuits distinguished between the groups. Findings revealed that somatomotor cortico-cerebellar and frontoparietal cortico-striatal circuits are affected in the presence of DCD, including abnormalities in cortico-cerebellar connections targeting motor-related regions and cortico-striatal connections mapping onto posterior parietal cortex. Thus, DCD but not DD may be considered as an impairment of cortico-subcortical functional circuits.

Symptoms of anxiety and depression in schoolchildren with and without developmental coordination disorder.

We examined whether reported higher frequencies of anxiety and depression symptoms are related to the presence of developmental coordination disorder in school-age Brazilian children. A total of 272 children were assigned to six groups according to age and motor performance. The Movement Assessment Battery for Children-Second Edition evaluated the motor performance. The Spence Children's Anxiety Scale and the Child Depression Inventory assessed anxiety and depression symptoms, respectively. Brazilian children are at high risk for anxiety, regardless of motor performance and age. However, children with developmental coordination disorder report significantly more depressive symptomatology in 10-12 years compared to typically developing children.

Fundamental motor skills of Czech children at the end of the preschool period

Background: Achievement of a sufficient fundamental motor skills (FMS) level by the end of the preschool period is an important premise for the later participation of children in many sports activities. However, only a few studies have focused on the assessment of motor proficiency before entrance to elementary school in the population of preschool children in the Czech Republic. Objective: The aim of this study was to assess the FMS of Czech boys and girls at the end of the preschool period. Methods: The Movement Assessment Battery for Children-second version (MABC-2) was used to assess the motor performance of the children in different domains, i.e., manual dexterity, aiming and catching, and balance. The research sample consisted of 121 children (age 6.5 ± 0.3 years, 61 boys and 60 girls). Results: According to the total test score performance on MABC-2, we found 2.5% of children with severe motor difficulties indicating the possible presence of Developmental Coordination Disorder and 10.7% of children with a risk of motor difficulties. In total, 64% of boys and 81.6% of girls had an MABC-2 score in the 50th percentile or lower. With respect to gender differences, boys outperformed girls in aiming and catching skills (p < .001; d = 1.10). Moreover, the girls' score in the 25th percentile indicated a low level of aiming and catching skills. Despite significantly better results for boys in one manual dexterity test item, and for girls in one manual dexterity and balance test item, there were no significant gender differences in overall manual dexterity and balance subtests. Conclusion: With the preschool years being a key developmental stage for the acquisition and development of FMS, the findings of low level of FMS in most of children and gender differences in aiming and catching skills highlight the need for improvements in motor competency. An effort should be made, especially for preschool girls, to stimulate the improvement of aiming and catching skills.

Impact of tactile function on upper limb motor function in children with Developmental Coordination Disorder

This study investigated the presence of, and relationship between tactile dysfunction and upper limb motor function in children with Developmental Coordination Disorder (DCD) compared to typical developing (TD) children. Participants were 36 children aged 6–12 years. Presence of DCD (n=20) or TD (n=16) was confirmed using the Movement Assessment Battery for Children, second edition. All children participated in a comprehensive assessment of tactile registration (Semmes Weinstein Monofilaments); tactile spatial perception (Single Point Localisation (SPL) and two-point discrimination (2PD)); haptic perception (Stereognosis); speed of simple everyday manual tasks (Jebsen–Taylor Test of Hand Function (JTTHF)); and handwriting speed and accuracy (Evaluation Tool of Children's Handwriting (ETCH)). Compared to TD children, children with DCD demonstrated poorer localisation of touch in the non-dominant hand (p=0.04), slower speed of alphabet writing (p<0.05) and less legible handwriting (p<0.01), but no difference in speed of simple everyday manual tasks (JTTHF: p>0.05). Regression analysis showed that spatial tactile perception (SPL) predicted handwriting legibility (ETCH: r=0.11) and speed of functional tasks (JTTHF: r=0.33). These results suggest that tactile function, specifically single point localisation, should be a primary tactile assessment employed to determine reasons for upper limb motor difficulties experienced by children with DCD.

Developmental coordination disorder and migraine in childhood

Purpose Migraine without aura (MoA) could be considered the most frequent form of primary headache in children, associated with many known comorbidities, but only the recent literature has begun to consider the importance of motor impairment linked to the attacks. The developmental coordination disorder (DCD) is a very common problem among children, with a prevalence ranging up to 19%. The aim of this study was to evaluate the presence of motor coordination impairment in a population of children affected by MoA, and its role as putative risk factor for motor skills impairment. Methods This observational study was performed in the Clinic of Child and Adolescent Neuropsychiatry of the Second University of Naples. MoA was diagnosed according to the International Classification of Headache Disorders (IHS-2) criteria. The study population consisted of 27 patients affected by MoA (16 females, 11 males) (mean age: 8.7 ± 2.15 years) and 59 typically developing children (34 females, 25 males) (mean age: 8.0 ± 2.1 years). The whole population underwent a clinical evaluation in order to assess the Total IQ level, the visual motor integration skills and the presence of DCD. Results Our results showed that MoA children had more impairments in motor coordination (p<0.001) and visual motor integration (p<0.001) than control group. Conclusion To our knowledge this is the first study to assess the association of poor motor coordination and MoA in children using. Objective measurements These findings suggest a new perspective in the management of migraine disease in children, pinpointing that the relationship between DCD and migraine could represent a not yet understood or identified comorbidity, even if further reports are necessary, and that migraine probably could be considered not only a painful syndrome in future.

Motor coordination impairment and migraine in children: a new comorbidity?

Migraine without aura (MoA) could be considered the most frequent form of primary headache in children, associated with many known comorbidities, but only the recent literature has begun to consider the importance of motor impairment linked to the attacks. The developmental coordination disorder (DCD) is a very common problem among children, with a prevalence ranging up to 19 %. The aim of this study was to evaluate the presence of motor coordination impairment in a population of children affected by MoA, and its role as putative risk factor for motor skills impairment.

MoA was diagnosed according to the International Classification of Headache Disorders (IHS-2) criteria. The study population consisted of 27 patients affected by MoA (16 females, 11 males) (mean age: 8.7 ± 2.15 years) and 59 typically developing children (34 females, 25 males) (mean age: 8.0 ± 2.1 years). The whole population underwent a clinical evaluation in order to assess the total IQ level, the visual motor integration skills, and the presence of DCD. Our results showed that MoA children had more impairments in motor coordination (p < 0.001) and visual motor integration (p < 0.001) than control group. To our knowledge, this is the first study to assess the association of poor motor coordination and MoA in children using objective measurements. These findings suggest a new perspective in the management of migraine disease in children, pinpointing that the relationship between DCD and migraine could represent a not yet understood or identified comorbidity, even if further reports are necessary, and that migraine probably could be considered not only a painful syndrome in future.

Developmental Coordination Disorder in School-Aged Children Born Very Preterm and/or at Very Low Birth Weight: A Systematic Review

: To systematically review and synthesize the literature to document the association between infants born very preterm and/or very low birth weight (VLBW) and the presence of developmental coordination disorder (DCD) at school age. : Seven databases were systematically searched. Studies were included if they examined very preterm (<32 weeks) and/or VLBW (<1500 g) infants to school age (age, 5-18 years), had a full-term and/or normal birth weight comparison group, and used a formal measure of motor impairment. Studies that included only infants who were small for gestational age or diagnosed with cerebral palsy were excluded. Two independent reviewers completed abstract and full-text screening, data extraction, and quality assessment of included studies. : Sixteen articles were included, with 7 studies incorporated into 2 meta-analyses using cutoff scores of either <5th or 5-15th percentile on the Movement Assessment Battery for Children. Both analyses showed a significant increase in the likelihood of DCD for children born very preterm and/or 1500 g or less, with odds ratios of 6.29 (95% confidence interval, 4.37-9.05, p < .00001) and 8.66 (95% confidence interval, 3.40-22.07, p < .00001) for <5th or 5-15th percentile scores, respectively. : Consistent across studies, DCD is more prevalent in the VLBW/very preterm population than full-term/normal birth weight control children and the general school-age population, with significantly greater odds of developing the disorder. Clinical practice should focus on early identification of and intervention for children with DCD, while research should focus on determining the mechanisms underlying DCD in the preterm population.

Effect of trampoline-based intervention program in static balance of children with developmental coordination disorder

Published studies have shown that the presence of developmental coordination disorder (DCD) (APA,1994), involves about 5–15% of the population. This work focused on the study of the effect of an...

A staged approach for identifying children with developmental coordination disorder from the population

The purpose of this study was to describe the motor, attention and intellectual characteristics of a population-based sample of children first screened for motor impairment and to discuss the recruitment and identification methods employed. A two stage cross-sectional, school-based survey was conducted to screen for children with motor coordination difficulties and to identify children with an existing diagnosis of attention deficit hyperactivity disorder/attention deficit disorder (ADHD/ADD). The identified children, and a random sample of typically developing children, were assessed to confirm or rule out the presence of developmental coordination disorder (DCD).Six thousand four hundred and seventy five children were invited to participate; 2943 children, with parental consent, completed the initial screening process. Two hundred eighty four children with possible motor impairment were identified. The parents of 113 children consented to a full assessment. Sixty eight children of the 113 children met diagnostic criteria for DCD, and 26 also had ADHD. Twenty eight of the 55 children who screened in with a diagnosis of ADHD were subsequently found to have DCD. The total number of children with confirmed characteristics of DCD was reduced after application of DCD diagnostic criteria. This study differs from others with regard to the additional screening for children with ADHD/ADD. The second stage assessment notably increased the number of children identified with both ADHD and DCD.

Movement Assessment Battery for Children (Movement ABC)

The Movement ABC (Henderson and Sugden 1992) is the most commonly reported norm-ranked assessment used to determine the presence of Developmental Co-ordination Disorder (DCD) in school-aged children. The assessment provides quantitative and qualitative data about a child’s performance of age-appropriate tasks within 3 subsections: Manual Dexterity, Ball Skills, and Static and Dynamic Balance. Performance is compared with established USA norms for children aged 4 to 12 years. The Movement ABC is a minimal task set designed to screen for motor impairment rather than provide a profile of a child’s motor performance. It takes approximately 30 minutes to administer and requires no special training.

Identifying Developmental Coordination Disorder

Summary In the absence of a gold standard to identify the presence of developmental coordination disorder in children, it is useful to examine the consistency of different tests used in physical and occupational therapy. This study examined three measures of motor skills to determine whether they consistently identified the same children. In total, 379 children participated in this study. The final matched samples consisted of 202 children ranging in age from 8 to 17 years: 101 met criteria for DCD and 101 children did not show any evidence of DCD. The results indicated that the overall agreement between the Bruininks Oseretsky Test of Motor Proficiency (BOT), the Movement Assessment Battery for Children (M-ABC) and the Developmental Coordination Disorder Questionnaire (DCDQ) was less than 80%. The difference in structure and style of administration between the BOT and the M-ABC appears to contribute to their tendency to identify different children. This studyemphasizes the need for therapists to use clinical reasoning to examine multiple sources of information about a child's abilities.
