RESUMEN

Developmental Coordination Disorder (DCD), also known as dyspraxia, affects 5-15% of school-aged children (Hamilton and Sutton, Am Fam Physician 66:1435, 2002) and significantly impacts a child's ability to learn motor skills and perform everyday activities efficiently and effectively (Zwicker et al., Eur J Paediatr Neurol 16:573-81, 2012). These motor deficits can have a negative impact on academic performance, vocational choices and leisure pursuits (Zwicker et al., Eur J Paediatr Neurol 16:573-81, 2012) and profoundly impact quality of life (Izadi-Najafabadi et al., Res Dev Disabil 84:75-84, 2019). DCD persists into adulthood (Kirby et al., J Adult Dev 18:107-13, 2011), impacting motor as well as emotional and behavioural status (Tal Saban and Kirby, Curr Dev Disord Rep 5:9-17, 2018). Despite the continued increase in research in the field of DCD, awareness of DCD remains poor (O'Kelly NL., From invisibility to invincibility: Guidelines for supporting families through the diagnosis and journey with developmental coordination disorder, 2012) even though it has higher prevalence rates when compared to, for example, autism spectrum disorder (Yan et al., J Autism Dev Disord :1-7, 2024), which in part may be due to a lack of accessible research findings. A fundamental feature of the research process is disseminating research findings. This should involve community members in design and delivery to ensure the accessibility of research findings.In 2022 the DCD-UK committee established a DCD Research Advisory Group (DCD-RAG) which met over the course of 12 months to: (1) identify issues of inaccessible research findings; (2) determine the need for a repository for research summaries; (3) co-create guidelines for authors and (4) agree a process for reviewing research summaries to be housed on the Movement Matters website. The new co-produced research repository, author guidelines and process were launched at the DCD-UK conference in Manchester 2023 and subsequently shared on social media and through the DCD research email list. The creation of the DCD-RAG and the process that we undertook together to create a non-academic repository for DCD research summaries are described. It is hoped that this repository will enable the wider public, community members and professionals to be able to readily benefit from accessible research, increasing a deeper and broader understanding of the evidence in the field.


Developmental Coordination Disorder (DCD) is also known as dyspraxia. DCD can affect a person's coordination, how they move and how they perform daily activities. It can impact quality of life and social and emotional wellbeing.Awareness of DCD is poor, so the DCD-UK committee started a Research Advisory Group, called DCD-RAG which includes adults with DCD and parents of children with DCD, to help them make information from DCD researchers more accessible.The group helped to identify the problems with gaining access to DCD research and they helped to write guidelines for researchers. They helped develop a website called Movement Matters for DCD researchers to file accessible summaries of their work. The group looked at how they could review summaries to ensure good practice.It is hoped the new website will help make DCD research from both the UK and internationally easier for the public and professionals to find, read and understand.Public involvement in research can be tokenistic. It is important that researchers allocate time to share findings with the people whose lives are the focus of the research.This article outlines how co-production with the public can improve the accessibility of research findings. Doing this in a way which is meaningful and accessible should be the minimum that researchers aim for.

RESUMEN

Previous studies have shown that children with Developmental Coordination Disorder (DCD)/Dyspraxia have poorer maths performance compared to their neurotypical (NT) counterparts. However, no studies have explored the cognitive and emotional factors affecting the maths performance of adults with DCD. This study, therefore, investigated the role of working memory (WM), maths anxiety (MAS), and maths self-efficacy on the maths performance of adults with DCD. We found that adults with DCD had lower WM and maths performance and were more maths anxious than their NT peers. However, there were no significant differences in maths self-efficacy. When looking at the predictors of maths performance, we found a positive relationship between WM resources and the DCD maths performance, possibly indicating that they relied more on WM resources to perform simple mental arithmetic tasks than NTs. On the other hand, MAS had an inverse relationship with the NT maths performance but not with the DCD performance. The reasons and implications of these findings will be discussed.

RESUMEN

Developmental Coordination Disorder (DCD) is a movement disorder in which atypical sensory processing may underly movement atypicality. However, whether altered sensory processing is domain-specific or global in nature, are unanswered questions. Here, we measured for the first time, different aspects of sensory processing and spatiotemporal integration in the same cohort of adult participants with DCD (N = 16), possible DCD (pDCD, N = 12) and neurotypical adults (NT, N = 28). Haptic perception was reduced in both DCD and the extended DCD + pDCD groups when compared to NT adults. Audio-visual integration, measured using the sound-induced double flash illusion, was reduced only in DCD participants, and not the DCD + pDCD extended group. While low-level sensory processing was altered in DCD, the more cognitive, higher-level ability to infer temporal dimensions from spatial information, and vice-versa, as assessed with Tau-Kappa effects, was intact in DCD (and extended DCD + pDCD) participants. Both audio-visual integration and haptic perception difficulties correlated with the degree of self-reported DCD symptoms and were most apparent when comparing DCD and NT groups directly, instead of the expanded DCD + pDCD group. The association of sensory difficulties with DCD symptoms suggests that perceptual differences play a role in motor difficulties in DCD via an underlying internal modelling mechanism.

RESUMEN

BACKGROUND: Navigation skills are essential for independent living as they allow us to explore our environment; find our way to new locations, refine pathways to familiar locations and retrace our route home. Alongside motor coordination difficulties, there is evidence that individuals with Developmental Coordination Disorder (DCD/Dyspraxia) experience spatial processing difficulties, which are known to negatively affect navigation abilities. However, although self-reports indicate that adults with DCD have difficulties with sense of direction and navigation, no known studies have measured navigation abilities and strategies in adults with DCD. Furthermore, given evidence that individuals with DCD report higher levels of anxiety, we will additionally investigate associations between anxiety and navigation in this group. AIMS: This study compares navigation abilities, navigation strategies and spatial anxiety in adults with and without DCD. METHODS: Participants include 226 Adults aged 18-55 years, across two groups 1) DCD (N = 138, 111 F:25 M; 2:Other) 2); Typically Developing (N = 88, 77 F: 11 M). In this cross-sectional study, participants completed a series of tasks on the online Qualtrics platform. This included the Adult Developmental Coordination Disorder Checklist, the State-Trait Anxiety Inventory, the Wayfinding Anxiety Measure, the Wayfinding Questionnaire, the Wayfinding Strategy Questionnaire, and a navigation task. RESULTS: Our analysis shows that 1) compared to those with typical development, individuals with DCD have similar navigation performance but lower navigation and orientation scores, and distance estimation scores. 2) Movement co-ordination difficulties were only a significant predictor of landmark recognition and egocentric path route knowledge, and played no role for other aspects of navigation performance. 3) For wayfinding strategy use the DCD group used orientation strategies significantly less often than those with typical development, however there was no group difference in the use of route strategies. 4) The DCD group had significantly higher spatial anxiety scores across navigation, manipulation and imagery spatial sub-domains, even after controlling for general anxiety. 5) Spatial navigation anxiety was a significant predictor of navigational skill for all three wayfinding measures (navigation & orientation, distance estimation and spatial anxiety). CONCLUSIONS: The findings establish benchmarks of navigational skills in DCD and highlight spatial anxiety and route strategies as factors that may inhibit navigation success and could help specify suitable intervention targets.

RESUMEN

Two paradigms were employed to disentangle information processing from executive motor inhibition in adults with Developmental Coordination Disorder (DCD). Choice Reaction and Stop Signal Tasks were compared between 13 adults fulfilling DSM-5 DCD criteria and 42 typically developing adults. Additional analyses included 16 probable DCD (pDCD) participants, who had motor difficulties but did not fulfil DSM-5 criteria. Analyses employed frequentist and Bayesian modeling. While DCD+pDCD showed slower reaction times and difficulty initiating Go responses, no impairments in Stop actions were found. These findings indicated no executive deficit in DCD, suggesting that previous results may be explained by inefficient information processing.

RESUMEN

Learning to drive is a significant event for the transition to adulthood and delay or avoidance may have social, practical, and psychological implications. For those with Developmental Coordination Disorder (DCD/Dyspraxia), driving presents a considerable challenge, and the literature shows that there are differences in driving ability between individuals with and without DCD. The aim of the current research is to further our understanding of the mechanisms underlying the driving experiences of individuals with DCD. Nineteen participants with DCD (10 drivers and 9 non-drivers) and 36 controls (17 drivers and 19 non-drivers) aged 18-57 years took part in this study. Participants completed standardized tests, questionnaires and a driving simulation task designed to measure speed, road positioning, and rate of change of steering in three conditions with increasing perceptual complexity. Results indicate that behaviors for all participants changed as the perceptual demands of the task increased. However, drivers with DCD were more affected than all other groups, driving more slowly, and driving further to the right. These findings illustrate how the impact of both internal and external constraints negatively affect the success of the driving task for individuals with DCD compared to their TD peers.

RESUMEN

BACKGROUND: Humans are highly social creatures who use others' movements to evaluate their social competencies. Smooth movement specifically signals an attractive, trustworthy or competent person. Those with Developmental Coordination Disorder (DCD), have peer relationship difficulties and lower sociometric preference scores. However, the relationship of perception of poor movement coordination to stereotyping has not been directly demonstrated. AIM: We aimed to describe typically developing individuals' social stereotyping of individuals with and without DCD from minimal visual cues. METHOD: 3D motion capture tracked the movement of four 'targets' (two adult males with DCD and two male controls) in a variety of everyday scenarios. Kinematic footage of the target's movements was presented as a point-light-display to 319 typically developing adults who used The Rating Scale of Social Competence to report perceptions of the target's social competencies. RESULTS: Targets with DCD were rated as having significantly lower social competence (M = 3.37, SD = 0.93) than controls (M = 3.46, SD = 0.89) t(269) = -5.656; p < 0.001, Cohen's d = 0.34. DISCUSSION: Humans incorporate minimal information on movement fluency to evaluate others' social competencies, including individuals with DCD. Such stereotyping may be automatic and may be an ill-understood mechanism sustaining persistent rejection by peers for individuals with DCD and higher rates of loneliness, isolation and mental disorders. In addition, our study expands research on competence-based stereotyping to a new applied domain, confirming the minimal cues needed to initiate stereotyping of the competencies of others.
