Coordination Disorder

Background: Developmental coordination disorder (DCD) has a negative impact on everyday activities and academic achievement in children, mainly owing to similar underlying motor and cognitive constructs. Academic achievement of boys and girls seems to be different, with boys being more prone to academic backlogs, especially in language-related areas.Aim: This study investigated if boys with DCD displayed more academic problems than girls with DCD.Setting: Ten-year-old children (N = 221, ±0.41) from different economic backgrounds were randomly selected for assessment as part of the NW-CHILD (North-West Child Health, Integrated with Learning and Development) longitudinal study in the North West Province of South Africa.Methods: The Movement Assessment Battery for Children, Second Edition, was used to determine DCD status in the group. The results of the Annual National Assessment and the mid-year June exam, which included six learning areas, were used to analyse academic differences between typically developing boys and girls and those who were identified with DCD (seven boys, seven girls). Independent t-testing and Mann–Whitney non-parametric tests were used to determine differences between boys and girls.Results: Boys with DCD had inferior literacy and numeracy skills, significantly poorer manual dexterity and balancing skills and also displayed statistically and large practically significant weaker mid-year grade point averages than girls. Children with DCD also portrayed poorer academic achievement than typically developing children.Conclusion: Significant differences in balancing skills and in languages between boys and girls with DCD might have contributed to the practically significant poorer maths performance of boys.

Brazilian Children

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.

Perceptual Abilities

Visual perception plays an important and integrating role in the development of cognitive abilities and perceptual-motor skills. Visual perception comprises different independent constructs that may function in an integrative manner. This study aimed to determine whether (and the extent to which) various visual-perceptual constructs influence the academic achievement of 12-year-old school children. In a cross-sectional analysis, we extracted only 2016 data from 581 learners (mean age = 12.92 years, SD = 0.42) who were participants in the North-West Child Health, Integrated with Learning and Development longitudinal study (2010–2016). We used the Test of Visual Perceptual Skills, Third Edition, the North-West Provincial Assessment and mid-year school examination reports to determine visual perceptual abilities and academic achievement of this participant group. We calculated correlations between visual perceptual constructs and academic performance using Spearman rank order correlations and separately analyzed the influence of gender and socioeconomic status with independent T tests. Different visual perceptual constructs did have significant influences on specific areas of academic learning and on academic achievement generally ( r = .26 to r = .41). Spatial relationships showed slightly greater correlations with academic achievement ( r = .15 to r = .33) than did other basic visual perceptual constructs, possibly because spatial relationships are not completely developed at age 12. Complex and basic visual perceptual skills had medium significant retrospective correlations with grade point average ( r = .40 and r = .41) and first additional language ( r = .30 and r = .33). We concluded that basic and complex visual perceptual constructs remain important for academic achievement in this age-group, while gender and socioeconomic status influence both visual perceptual abilities and academic achievement.

Condition Interaction

This study examined and compared the control of posture during bilateral stance in ten boys with Developmental Coordination Disorder (DCD) of 6-8 years old and ten matched typically developing boys in four sensory conditions (with or without vision, on a firm or complaint surface). In all conditions mean postural sway velocity was larger for the boys with DCD, in spite of a normal score on the balance items of the Movement Assessment Battery for Children. A Group X Condition interaction revealed a larger dependency on vision in the boys with DCD when standing on a firm surface. These results suggest that in this specific subgroup of boys with DCD with predominantly problems in fine motor and ball skills postural control problems may still be prevalent and may possibly be associated with difficulties to re-weight sensory information in response to environmental demands.

Abstract Background and Purpose. Physical therapists' teaching skills often are disregarded in research studies. We examined whether the use of different teaching principles during neuromotor task training was associated with treatment effects. Subjects. Nineteen children (mean age=7 years 5 months, range=5–10 years) who had developmental coordination disorder and who performed below the 15th percentile on the age-related Movement Assessment Battery for Children (M-ABC) and 11 physical therapists participated in the study. Methods. One intervention session for each child was videotaped. The frequency of the use of principles included in the motor teaching principles taxonomy (Niemeijer et al, 2003) was correlated with changes in motor performance on the M-ABC and the second edition of the Test of Gross Motor Development. Results. Providing clues on how to perform a task, asking children about a task, and explaining why a movement should be executed in a certain way were related to better movement performance. Discussion and Conclusion. Teaching principles may be associated with success in therapeutic situations.

В статье рассмотрены приёмы восстановления высокоурожайного сорта клевера лугового Псковский местный двуукосный селекции Псковского НИИСХ с целью возвращения его в сельскохозяйственное производство Северо-Западного региона РФ. Сорт Псковский местный двуукосный отличается высокой урожайностью, продуктивным долголетием и устойчивостью к неблагоприятным факторам среды. Имеет повышенный спрос у производственников Псковской области. Однако отсутствие семеноводства, проблемы с выдачей сортовых и посевных документов сдерживают его распространение. Большой интерес представляет использование данного сорта в селекционной работе. В 2018–2020 годах в питомнике ОП Псковского НИИСХ были изучены семь образцов этой культуры (П-101–П-107), полученных из хозяйств области. Посеянные семена собраны с неапробированных посевов предположительно сорта Псковский местный двуукосный, который возделывался в хозяйствах многие годы. Для сравнительного анализа оригинал сорта получили из коллекции ВИР (К-31744). В результате определения типа созревания образцов по количеству междоузлий на стебле и построения вариационных кривых образцы П-103, П-106, П-107 отнесли к позднеспелому типу клевера лугового, что указало на их несоответствие оригиналу. Наиболее близкими по этому показателю к оригиналу оказались образцы П-101, П-102, П-104, П-105. По морфологическим признакам наибольшее сходство с оригиналом имели образцы П-101, П-102, П-103. Методом SDS-электрофореза белковых спектров выявили три позиции, по которым исследованные образцы неапробированных посевов (П-101, П-102, П-103) отличались от К-31744. Для восстановления сорта Псковский местный двуукосный в качестве исходного материала перспективно использование образцов П-101 и П-102 как наиболее схожих с оригиналом по срокам созревания и морфологии. Метод SDS-электрофореза позволяет контролировать селекционные образцы на идентичность сортам клевера лугового. This article reports on the experiment aimed at improving the performance of red clover “Pskovskiy mestnyy dvuukosnyy” to be cultivated in the North-West region of Russia. The variety was bred at the Pskov Agricultural Research Institute and has high productivity, productive longevity and resistance to environmental stresses. This variety is well-known among the farmers in the Pskov region. However poor seed production together with paper issues have negative impact on its wide cultivation. “Pskovskiy mestnyy dvuukosnyy” is a valuable material for plant breeding. In 2018–2020 the Pskov Agricultural Research Institute collected seven red clover specimens (P-101–P-107) from the regional farms. The collected seeds potentially belonged to the “Pskovskiy mestnyy dvuukosnyy” variety. The original variety was obtained from the Federal Research Center N. I. Vavilov All-Russian Institute of Plant Genetic Resources (VIR) as a control (K-31744). As a result, P-103, P-106, and P-107 were shown to be long-seasoned and therefore differed from the control. P-101, P-102, P-104, and P-105 were more similar to the control in their maturation rate. However, P-101, P-102, P-103 morphologically were closer to the original variety. SDS-PAGE showed that P-101, P-102, and P-103 differed from the control (K-31744). P-101 and P-102 were used as parent material to improve “Pskovskiy mestnyy dvuukosnyy” since they were more similar to the one.

Background: Early identification of learners in low socio-economic environments with possible developmental coordination disorder (DCD) is important. Although various screening tools are available, it is unclear whether teachers can use the movement assessment battery for children - second edition checklist (MABC-2 checklist) to identify learners with possible DCD.Aim: To establish teachers’ ability to identify Grade 1 learners in low socio-economic environments with possible DCD.Setting: The study was conducted in the Mangaung Metro, Motheo District of the Free State Province, South Africa. Grade 1 learners aged 6–8 years (n = 200) from a low socio-economic environment attending quintile one to three schools were randomly selected for assessment. Twenty-nine teachers participated in the study.Methods: Kinderkineticists identified learners with possible DCD (displaying motor skills far below the child’s age) by means of the MABC-2 performance test. The teachers used the MABC-2 checklist to identify possible DCD. The convergent validity of the MABC-2 performance test and checklist was compared.Results: The convergent validity between the MABC-2 performance test and the MABC-2 checklist indicated a kappa (k) coefficient of 0.17, indicating a slight agreement between the performance test and the checklist. Overall, the specificity was 58% (105/180), and the sensitivity was 85% (17/20).Conclusion: Teachers could effectively identify learners with possible DCD. However, they demonstrated a low ability to identify learners without possible DCD when using the MABC-2 checklist. It is therefore recommended that the performance test should be used in conjunction with the checklist to obtain the most reliable results.

AbstractWhile evidence suggests that children with the developmental coordination disorder (DCD) have worse health outcomes than their typically developing peers, it remains unclear whether children with low motor competence but without DCD are also characterized by worse health outcomes than those with average motor competence. The main purpose of this study was to compare health outcomes between children with low motor competence without DCD and those with average motor competence.The total of 127 children aged 12–14 years were recruited. Motor competence, physical activity, flexibility, and muscular strength/endurance were assessed with, respectively, the Körperkoordinationstest für Kinder, a validated self-administered questionnaire, sit-and-reach, and sit-up 60s tests. Skinfold thickness was measured to assess the children’s adiposity. Multivariate analysis of variance, Kruskal-Wallis, and Mann-Whitney tests were performed.Children with average motor competence had lower body fat percentage and higher levels of physical activity and muscular strength/endurance than the groups with low (Our findings suggest that children with low motor competence without DCD have worse health outcomes than their peers with average motor competence. We suggest that both the development of motor competence and improvement of health outcomes should be targeted during childhood and adolescence by health professionals.
