The United Kingdom and Ireland have a well-established research base in motor competence (MC) research, ranging from reporting and monitoring levels of MC, developing assessment tools for MC, providing innovative curriculum and intervention design to support learning and development, as well as providing advocacy for particular groups, such as those with motor impairments. This expert statement, on behalf of the International Motor Development Research Consortium, draws together what is currently known about levels of MC in the United Kingdom and Ireland as well as current approaches to intervention in both countries. Subsequently presented are recommendations for researchers and practitioners to advance the field of MC for the benefit of children and youth in the United Kingdom, Ireland, and worldwide.

Handwriting difficulties are frequently mentioned in descriptions of developmental coordination disorder (DCD). Recent studies have shown that children with DCD pause more and produce less text than typically developing (TD) peers. This temporal dysfluency indicates a lack of automaticity in handwriting production. One possible contributing factor is the accuracy and consistency of letter formation. The aim of this study was to gain a better understanding of handwriting dysfluency by examining the accuracy and consistency of letter production both within and across different writing tasks. A total of 28 children aged 8 to 15 years with DCD participated in the study with 28 TD age- and gender-matched control participants. They completed the alphabet writing and copy fast tasks from "The Detailed Assessment of Speed of Handwriting" on a digitizing writing tablet. The accuracy and consistency of letter production were examined. The DCD group had a higher percentage of errors within their letterforms than did the TD peers. Letter production was also less consistent between tasks. Children with DCD appear to have difficulties with the "allograph" (motor program) aspect of handwriting and may require explicit teaching of letter formation.

Movement, which draws on motor skills and executive functions for managing them, plays an important role in literacy learning (e.g., movement of mouth during oral reading and movement of hand and fingers during writing); but relatively little research has focused on movement skills in students with specific learning disabilities as the current study did. Parents completed normed "Movement Assessment Battery for Children Checklist, 2nd edition" (ABC-2), ratings and their children in grades 4 to 9 (M = 11 years, 11 months; 94 boys, 61 girls) completed diagnostic assessment used to assign them to diagnostic groups: control typical language learning (N = 42), dysgraphia (impaired handwriting) (N = 29), dyslexia (impaired word decoding/reading and spelling) (N = 65), or oral and written language learning disability (OWL LD) (impaired syntax in oral and written language) (N = 19). The research aims were to (a) correlate the "Movement ABC-2" parent ratings for Scale A Static/Predictable Environment (15 items) and Scale B Dynamic/ Unpredictable Environment (15 items) with reading and writing achievement in total sample varying within and across different skills; and (b) compare each specific learning disability group with the control group on "Movement ABC-2" parent ratings for Scale A, Scale B, and Scale C Movement-Related (Non-Motor Executive Functions, or Self-Efficacy, or Affect) (13 items). At least one "Movement ABC-2" parent rating was correlated with each assessed literacy achievement skill. Each of three specific learning disability groups differed from the control group on two Scale A (static/predictable environment) items (fastens buttons and forms letters with pencil or pen) and on three Scale C items (distractibility, overactive, and underestimates own ability); but only OWL LD differed from control on Scale B (dynamic/unpredictable environment) items. Applications of findings to assessment and instruction for students ascertained for and diagnosed with persisting specific learning disabilities in literacy learning, and future research directions are discussed.

The ability to finely control our movement is key to achieving many of the educational milestones and life-skills we develop throughout our lives. Despite the centrality of coordination to early development, there is a vast gap in our understanding of the underlying biology. Like most complex traits, both genetics and environment influence motor coordination, however, the specific genes, early environmental risk factors and molecular pathways are unknown. Previous studies have shown that about 5% of school-age children experience unexplained difficulties with motor coordination. These children are said to have Developmental Coordination Disorder (DCD). For children with DCD, these motor coordination difficulties significantly impact their everyday life and learning. DCD is associated with poorer academic achievement, reduced quality of life, it can constrain career opportunities and increase the risk of mental health issues in adulthood. Despite the high prevalence of coordination difficulties, many children remain undiagnosed by healthcare professionals. Compounding under-diagnosis in the clinic, research into the etiology of DCD is severely underrepresented in the literature. Here we present the first genome-wide association study to examine the genetic basis of early motor coordination in the context of motor difficulties. Using data from the Avon Longitudinal Study of Parents and Children we generate a derived measure of motor coordination from four components of the Movement Assessment Battery for Children, providing an overall measure of coordination across the full range of ability. We perform the first genome-wide association analysis focused on motor coordination (N = 4542). No single nucleotide polymorphisms (SNPs) met the threshold for genomewide significance, however, 59 SNPs showed suggestive associations. Three regions contained multiple suggestively associated SNPs, within five preliminary candidate genes: IQSEC1, LRCC1, SYNJ2B2, ADAM20, and ADAM21. Association to the gene IQSEC1 suggests a potential link to axon guidance and dendritic projection processes as a potential underlying mechanism of motor coordination difficulties. This represents an interesting potential mechanism, and whilst further validation is essential, it generates a direct window into the biology of motor coordination difficulties. This research has identified potential biological drivers of DCD, a first step towards understanding this common, yet neglected neurodevelopmental disorder. [ABSTRACT FROM AUTHOR]

Students must be able to produce legible and fluent text when completing classwork and for exam purposes. Some students, however, present with handwriting difficulties in secondary school. When these are significant, intervention may be necessary or alternatives to handwriting may be offered (e.g. use of a word processor). Little is known about current practice of supporting secondary students with handwriting difficulties in England and how recommendations are made to transition to typing. Semi‐structured interviews were conducted with 13 practitioners with a responsibility for supporting students with handwriting difficulties. Two themes were identified. The first theme, 'doing the right thing', illustrated the tension between practitioners' commitment to supporting students with handwriting difficulties and their uncertainty around what is the 'right' approach. The second theme, 'influencing practice', described the contextual factors (student and family, school environment and national context) that impact on practitioners' practice and their decision to transition from handwriting to typing. Findings highlight the complexities of supporting this group of students and an urgent need for guidance at a national level to assist best practice. Implications for practice are discussed. Further research examining the effectiveness of handwriting interventions with secondary students and the optimum time to start typing is warranted. [ABSTRACT FROM AUTHOR]

Spelling is a prerequisite to expressing vocabulary in writing. Research has shown that children with dyslexia are hesitant spellers when composing. This study aimed to determine whether the hesitant spelling of children with dyslexia, evidenced by frequent pausing, affects vocabulary choices when writing. A total of 31 children with dyslexia, mean age 9 years, were compared to typically developing groups of children: the first matched by age, the second by spelling ability. Oral vocabulary was measured and children completed a written and verbal compositional task. Lexical diversity comparisons were made across written and verbal compositions to highlight the constraint of having to select and spell words. A digital writing tablet recorded the writing. Children with dyslexia and the spelling-ability group made a high proportion of spelling errors and within-word pauses, and had a lower lexical diversity within their written compositions compared to their verbal compositions. The age-matched peers demonstrated the opposite pattern. Spelling ability and pausing predicted 53% of the variance in written lexical diversity of children with dyslexia, demonstrating the link between spelling and vocabulary when writing. Oral language skills had no effect. Lexical diversity correlated with written and verbal text quality for all groups. Practical implications are discussed and related to writing models.

Current models of writing do not sufficiently address the complex relationship between the 2 transcription skills: spelling and handwriting. For children with dyslexia and beginning writers, it is conceivable that spelling ability will influence rate of handwriting production. Our aim in this study was to examine execution speed and temporal characteristics of handwriting when completing sentence-copying tasks that are free from composing demands and to determine the predictive value of spelling, pausing, and motor skill on handwriting production. Thirty-one children with dyslexia (M[subscript age] = 9 years 4 months) were compared with age-matched and spelling-ability matched children (M[subscript age] = 6 years 6 months). A digital writing tablet and Eye and Pen software were used to analyze handwriting. Children with dyslexia were able to execute handwriting at the same speed as the age-matched peers. However, they wrote less overall and paused more frequently while writing, especially within words. Combined spelling ability and within-word pausing accounted for over 76% of the variance in handwriting production of children with dyslexia, demonstrating that productivity relies on spelling capabilities. Motor skill did not significantly predict any additional variance in handwriting production. Reading ability predicted performance of the age-matched group, and pausing predicted performance for the spelling-ability group. The findings from the digital writing tablet highlight the interactive relationship between the transcription skills and how, if spelling is not fully automatized, it can constrain the rate of handwriting production. Practical implications are also addressed, emphasizing the need for more consideration to be given to what common handwriting tasks are assessing as a whole.

It is commonly assumed that children with dyslexia are slower at handwriting than other children. However, evidence of slow handwriting in children with dyslexia is very mixed. Thirty-one children with dyslexia, aged 9 years, were compared to both age-matched children and younger spelling-ability matched children. Participants completed an alphabet-writing task and a composition task on the surface of a digital writing tablet. Children with dyslexia wrote the same amount of letters per minute in the alphabet task but wrote fewer words per minute when composing their texts than children of the same age. Crucially, no differences were found between children with dyslexia and their same age peers for speed of handwriting execution, measured by the tablet, when writing the alphabet or composing their texts. However, children with dyslexia were found to pause within their compositions as often as the spelling ability matched group. Thus handwriting execution is not impaired in children with dyslexia. The slow writing that is typical of children with dyslexia is due to pausing more often when composing and is related to spelling ability. This may reflect processing problems in response to high cognitive load through having to contend with spelling and composing concurrently.

When picking up an object, adults show a longer deceleration phase when the onward action has a greater precision requirement. Tailoring action in this way is thought to need forward modelling in order to predict the consequences of movement. Some evidence suggests that young children also tailor reaching in this way; however, how this skill develops in children with Developmental Coordination Disorder (DCD) is unknown. The current study compared the kinematics of reaching to an object when the onward intention was: to place the object on a target (either with high or low precision requirements), to throw the object or to lift the object vertically. Movements of both adults (N = 18) and children (N = 24) with DCD and their age-matched controls were recorded. The typically developing adults discriminated across all action types, the adults with DCD and the typically developing children only across the actions to place and throw and the children with DCD only between the actions to lift and throw. The results demonstrate developmental progression towards fine tuning the planning of reaching in relation to onward intentions. Both adults and children with DCD are able to plan movement using inverse models but this skill is not yet fully developed in early adulthood. (Contains 2 tables and 3 figures.)

A description of Developmental Coordination Disorder (DCD) is included in the "Diagnostic Manual of the American Psychiatric Association" fourth edition ("DSM-IV-TR"). The major feature of this condition is impairment in motor skill, which has a negative impact on the performance of everyday life tasks. The present review outlines major issues concerning the assessment of motor performance in DCD. First, the psychometric principles of reliability and validity are considered, together with a discussion of test norms. This is followed by a review of 5 major purposes of assessment: screening and identification, measurement of motor performance, making a diagnosis, understanding the nature and mechanisms of the condition, and planning for intervention. In each case, the relevant assessment tools are identified and their application discussed. The article concludes with recommendations for future work, which include the need to refine the DCD diagnostic criteria in order to offer a more principled approach to the selection of assessment techniques. (Contains 2 tables.)

Individuals with developmental coordination disorder (DCD) experience motor skill and executive function (EF) difficulties that challenge their daily activities. This systematic review aims to provide an in-depth analysis of the relationships between motor skills and EFs in studies among individuals with DCD. We conducted a systematic search of eight electronic databases for articles (published 1994–2021) reporting on quantitative studies that estimated relationships between motor skills and EFs when assessing children, adolescents and adults with DCD. Motor skills and EFs were assessed via reliable and validated assessment tools. Two reviewers independently screened the articles. We evaluated the quality of the selected articles according to EPHPP guidelines and the methodological quality of the assessments from these studies using the COSMIN checklist and reported results following the PRISMA-P checklist. This systematic review was registered in PROSPERO (CRD42019124578). A total of 30,808 articles were screened. Eleven articles met the inclusion criteria and were reviewed. Findings from nine studies demonstrated weak to strong correlations between aspects of motor skills and EFs. Limited evidence supports the relationships between motor skills and EFs among individuals with DCD. Occupational therapists should consider the possibility of this relationship and give more consideration to these components when planning intervention for individuals with DCD. [ABSTRACT FROM AUTHOR]
