RESUMO

Children with Developmental Coordination Disorder (DCD) demonstrate inefficient motor planning ability with a tendency to opt for non-optimal planning strategies. Motor imagery can provide an insight to this planning inefficiency, as it may be a strategy for improving motor planning and thereby motor performance for those with DCD. In this study, we investigated the prevalence of end-state-comfort (ESC) and the minimal rotation strategy using a grip selection task in children with DCD with and without motor imagery instructions. Boys with (n = 14) and without DCD (n = 18) aged 7-12 years completed one, two and three colour sequences of a grip selection (octagon) task. Two conditions were examined; a Motor Planning (MP) condition requiring only the performance of the task and a Motor Imagery and Planning (MIP) condition, which included an instruction to imagine performing the movement before execution. For the MP condition, children with DCD ended fewer trials in ESC for the one (p = 0.001) and two colour (p = 0.002) sequences and used a minimal rotation strategy more often than those without DCD. For the MIP condition, the DCD group significantly increased their use of the ESC strategy for the one colour sequences (p = 0.014) while those without DCD improved for the two colour (p = 0.008) sequences. ESC level of the DCD group on the MIP condition was similar to those without DCD at baseline for all colour sequences. Motor imagery shows potential as a strategy for improving motor planning in children with DCD. Implications and limitations are discussed.

RESUMO

AIM: To examine cross-sectional differences in patterns of daily physical activity accumulation between preschool children at risk for developmental coordination disorder (DCD) compared to typically developing children. METHOD: In total, 514 children (292 males, 222 females; 4-5y) were recruited as part of the Coordination and Activity Tracking in CHildren (CATCH) study. Motor competence was assessed using the Movement Assessment Battery for Children, Second Edition; children scoring ≤5th centile comprised the probable DCD group (pDCD, n=87), between the 6th and 16th centile were considered to be at risk for DCD (rDCD, n=149), and >16th centile were considered typically developing (n=278). Seven-day physical activity was measured using hip-worn accelerometers. Average daily intensity of activity, frequency, and duration of moderate-to-vigorous physical activity (MVPA) bouts, and triaxial activity counts per minute were determined. RESULTS: No differences in daily activity in any intensity or axis of movement were found among the three groups. However, young children with pDCD accumulated their MVPA in slightly shorter bouts compared to typically developing children. INTERPRETATION: Young children at risk for DCD are not yet in an activity deficit. This may be because of the low motor skill demands of play in this age group. Early motor interventions may be able to promote continued physical activity participation in children with DCD. WHAT THIS PAPER ADDS: Preschool children at risk for developmental coordination disorder (DCD) are not less active than their peers. Overall intensity and frequency of daily activity bouts are similar among motor groups. Children with probable DCD accumulate their activity in shorter bouts.

RESUMO

Deficits in motor skills and depressive symptoms are common effects observed after stroke, so it is necessary to understand how these variables interact with each other. Therefore, the aim of this study was to investigate the relationship between these two variables in post-ischemic stroke patients. We evaluated 135 patients with a mean age of 60 years (± 15). The Fugl-Meyer assessment of motor function was used to assess motor skills in the upper limbs, lower limbs, balance, and sensitivity and the Beck Depression Inventory was applied to evaluate depressive symptoms. To assess the relationship between both components, Spearman's correlation was performed. Depressive symptoms were negatively correlated with all variables of motor skills. This study suggests that higher motor skills in post-stroke patients may be associated with fewer depressive symptoms. Thus, a better understanding of how post-stroke symptoms are interrelated may improve patient treatment and care, contributing to a better quality of life.

RESUMO

The aim of this study was to determine the effects of different attentional focus conditions (external focus (EF) vs. internal focus (IF) vs. no focus (NF)) on the performance of a pole-holding task and postural stability in children with developmental coordination disorder (DCD) and typically developing children (TDC), while addressing previous study limitations. A total of 186 participants were enrolled in the analysis comprising 91 children with DCD (28 in the EF, 32 in the IF, and 31 in the NF condition) and 95 TDC (31 in the EF, 33 in the IF, and 31 in the NF condition). Participants were required to hold a pole with their hands still and parallel to the floor while focusing on pole movement (EF), focusing on hands (IF), or without focus instructions (NF), while pole movements and postural sway were recorded. Results showed that pole movements were significantly smaller during the EF condition (p < 0.05) compared with IF and NF conditions for both the DCD and TDC groups. In addition, postural sway was significantly lower during the EF condition compared with IF and NF conditions (p < 0.05). This study verified that the EF condition can not only facilitate better performance in holding a pole horizontal and immobile, but also concurrently promote greater postural stability than both IF and NF conditions for children with DCD and TDC.

RESUMO

BACKGROUND: Children with developmental coordination disorder (DCD) have lower physical activity (PA) than children with typical development (TD). PA and fundamental movement skills (FMS) are positively associated so interventions that promote FMS of children with DCD are recommended. AIM: To examine the effects of a school-based FMS training program on motor functions, PA and other psychological outcomes. METHODS AND PROCEDURES: A total of 131 primary children were allocated to FMS training groups (DCD-FMS n = 35, TD-FMS n = 29), which received FMS training (eight weekly 40-min sessions), or to control groups (DCD-C n = 34, TD-C n = 33), which received conventional physical education lessons. Outcome measures, including accelerometer-assessed PA, motor functions, and self-perceived competence and enjoyment, were measured at baseline, 1-week (immediate effect), 3-months (short-term effect) and 12-months (longer-term effect) after the intervention. OUTCOMES AND RESULTS: FMS training resulted in improved FMS proficiency and increased PA and enjoyment of activity participation in children. In particular, the DCD-FMS group reported greater enjoyment over time. Some effects were also evident for both short- and longer-term. CONCLUSIONS AND IMPLICATIONS: The findings suggest that a school-based FMS training program has the potential to promote physical and psychological health in children with DCD in the long run.

RESUMO

Developmental coordination disorder (DCD) is a neurodevelopmental disorder affecting the motor system, but it may also present with signs of somatosensory dysfunction. This study examined whether haptic perception, which relies on somatosensory afferents, is impaired in children with DCD. Haptic sensitivity and acuity were systematically quantified in children with DCD and contrasted to the performance of typically developing (TD) children and young adults (each group N = 20). All participants performed a curvature detection task measuring haptic sensitivity and a curvature discrimination task measuring haptic acuity. In both tasks, participants moved the index finger of their dominant hand over a surface contour and verbally indicated whether they could detect its curvature or discriminate between two curved contours. Based on their verbal responses haptic detection and discrimination thresholds were obtained. The main findings are as follows: First, the DCD group had significantly elevated haptic discrimination thresholds (lower haptic acuity) compared to both TD children and adult controls. Second, we found no evidence that haptic sensitivity is impaired in DCD. Third, haptic acuity significantly correlated with clinical motor measures, indicating that higher levels of haptic acuity were associated with higher motor abilities. We conclude that DCD may be associated with impaired haptic perception, which likely contributes to the observable fine motor deficits.

RESUMO

AIM: These international clinical practice recommendations (CPR) for developmental coordination disorder (DCD), initiated by the European Academy of Childhood Disability (EACD), aim to address key questions on the definition, diagnosis, assessment, intervention, and psychosocial aspects of DCD relevant for clinical practice. METHOD: Key questions in five areas were considered through literature reviews and formal expert consensus. For recommendations based on evidence, literature searches on 'mechanisms', 'assessment', and 'intervention' were updated since the last recommendations in 2012. New searches were conducted for 'psychosocial issues' and 'adolescents/adults'. Evidence was rated according to the Oxford Centre for Evidence-Based Medicine (level of evidence [LOE] 1-4) and transferred into recommendations. For recommendations based on formal consensus, two meetings of an international, multidisciplinary expert panel were conducted with a further five Delphi rounds to develop good clinical practice (GCP) recommendations. RESULTS: Thirty-five recommendations were made. Eight were based on the evidence from literature reviews (three on 'assessment', five on 'intervention'). Twenty-two were updated from the 2012 recommendations. New recommendations relate to diagnosis and assessment (two GCPs) and psychosocial issues (three GCPs). Additionally, one new recommendation (LOE) reflects active video games as adjuncts to more traditional activity-oriented and participation-oriented interventions, and two new recommendations (one GCP, one LOE) were made for adolescents and adults with DCD. INTERPRETATION: The CPR-DCD is a comprehensive overview of DCD and current understanding based on research evidence and expert consensus. It reflects the state of the art for clinicians and scientists of varied disciplines. The international CPR-DCD may serve as a basis for national guidelines. WHAT THIS PAPER ADDS: Updated international clinical practice guidelines on developmental coordination disorder (DCD). Refined and extended recommendations on clinical assessment and intervention for DCD. A critical synopsis of current research on mechanisms of DCD. A critical synopsis of psychosocial issues in DCD, with implications for clinical practice. The first international recommendations to consider adolescents and adults with DCD.

RESUMO

OBJECTIVE: To compare, by collection time and patient characteristics, inpatient rehabilitation quality measure scores calculated using patient-reported data. DESIGN: Cohort study of rehabilitation inpatients with neurologic conditions who reported their experience of care and pain status at discharge and 1month after discharge. SETTING: Two inpatient rehabilitation facilities (IRFs). PARTICIPANTS: Patients with neurologic conditions (N=391). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: We calculated 18 quality measure scores using participants' responses to 55 experience of care and health status questions addressing communication, support and encouragement, care coordination, discharge information, goals, new medications, responsiveness of staff, cleanliness, quietness, pain management, care transitions, overall hospital rating, willingness to recommend, and pain. RESULTS: Of the 391 participants reporting at discharge, 277 (71%) also reported postdischarge after multiple attempts by e-mail, mail, and telephone. Discharge experience of care quality scores ranged from 25% (responsiveness of hospital staff) to 75% (willingness to recommend hospital); corresponding postdischarge scores were 32% to 87%, respectively. Five of the 16 experience of care quality scores increased significantly between discharge and postdischarge. The percentage of participants reporting high pain levels at discharge did not change across time periods. Patients with less education, older age, higher motor and cognitive function, and those who were not Hispanic or black had more favorable quality measure scores. CONCLUSION: Patients' experience of care responses tended to be more favorable after discharge compared to discharge, suggesting that survey timing is important. Responses were more favorable for patients with selected characteristics, suggesting the possible need for risk adjustment if patient-reported quality measure scores are compared across IRFs.

RESUMO

BACKGROUND: Autism spectrum disorder (ASD) is a heterogeneous group of neurodevelopmental disorders which core symptoms are impairments in socio-communication and repetitive symptoms and stereotypies. Although not cardinal symptoms per se, motor impairments are fundamental aspects of ASD. These impairments are associated with postural and motor control disabilities that we investigated using computational modeling and developmental robotics through human-machine interaction paradigms. METHOD: First, in a set of studies involving a human-robot posture imitation, we explored the impact of 3 different groups of partners (including a group of children with ASD) on robot learning by imitation. Second, using an ecological task, i.e. a real-time motor imitation with a tightrope walker (TW) avatar, we investigated interpersonal synchronization, motor coordination and motor control during the task in children with ASD (n=29), TD children (n=39) and children with developmental coordination disorder (n=17, DCD). RESULTS: From the human-robot experiments, we evidenced that motor signature at both groups' and individuals' levels had a key influence on imitation learning, posture recognition and identity recognition. From the more dynamic motor imitation paradigm with a TW avatar, we found that interpersonal synchronization, motor coordination and motor control were more impaired in children with ASD compared to both TD children and children with DCD. Taken together these results confirm the motor peculiarities of children with ASD despite imitation tasks were adequately performed. DISCUSSION: Studies from human-machine interaction support the idea of a behavioral signature in children with ASD. However, several issues need to be addressed. Is this behavioral signature motoric in essence? Is it possible to ascertain that these peculiarities occur during all motor tasks (e.g. posture, voluntary movement)? Could this motor signature be considered as specific to autism, notably in comparison to DCD that also display poor motor coordination skills? We suggest that more work comparing the two conditions should be implemented, including analysis of kinematics and movement smoothness with sufficient measurement quality to allow spectral analysis.

RESUMO

Empathy is defined as an emotional or cognitive response to another's emotional state. It is considered essential for navigating meaningful social interactions and is closely linked to prosocial behavior. Developmental coordination disorder (DCD) is characterized by an impairment of motor coordination that has a marked impact on both academic and day-to-day living activities. Children and adolescents with DCD have been shown to have less developed social support and friendships. The research linking empathy and DCD is scarce. The aims of this study are to gain an understanding of the relationship between DCD and empathy in young adults with DCD only, and with DCD coupled with other neurodevelopmental disorders, in comparison with typically developing adults. METHODS: The study included 212 young adults aged 18-40 years. The subjects in this study were from mainstream populations in the UK. The study groups included: (a) "DCD only" with 42 individuals; (b) "DCD + ASD" with 21 individuals; (c) "DCD + ADHD" with 45 individuals; (d) "DCD + ASD + ADHD" with 29 individuals; and (e) the control group of 75 individuals. RESULTS: ANOVA on the Empathy Questionnaire (EQ) showed a statistically significant difference between groups (F [4,257] = 35.63; p < 0.001; ηp2 = 0.409). No significant differences were found between the DCD-only and the control. MANOVA was performed to assess differences in the Socialising and Friendship Questionnaire (SAF-Q) scores. The results showed a statistically significant difference between groups (F [8,257] = 9.98; p < 0.001; η = 0.162). Pearson correlation coefficients were performed, revealing significant high correlations between the EQ and the two parts of the SAF-Q ("past" and "currently"). CONCLUSION: The results of this study indicate that social difficulties in the DCD-only group are not due to lack of empathy, but may be driven by an accumulation of external factors. In this study we also concluded that DCD does not appear to be the factor that reduces the ability to empathize, but rather the presence of ADHD and/or ASD.

RESUMO

Objectives. To determine the feasibility of recruiting families of children with suspected or diagnosed developmental coordination disorder (sdDCD) and explore their satisfaction with a web-based intervention Design. A feasibility randomized trial was conducted. Participants were the parents of 5-12-year-old children with sdDCD. The intervention group had access to online resources, group and private forums, and videoconferencing with a therapist. Main outcomes were recruitement and retention rates. Satisfaction was documented through a post-intervention survey and interview. Results. The recruitment rate was seven participants per month (n = 28 participants) and retention rate was 68%. Satisfaction was moderate. No differences in use and satisfaction were observed between groups. Participants formulated recommendations for improving the intervention, including targeting families earlier in the diagnosis process, and pre-scheduling meetings with therapists. Conclusions. This study demonstrated the feasibility of future trials, and highlighted avenues for improvement. Parent involvement during the development of the intervention is discussed at length. Abbreviations: DCD: Developmental Coordination Disorder; sdDCD: suspected or diagnosed Developmental Coordination Disorder; RCT: randomized-controled trial.

RESUMO

BACKGROUND AND AIMS: The Environmental Stress Hypothesis (ESH) has been used to examine how the relationship between poor motor coordination and psychological distress is affected by physical health and psychosocial factors. However, work applying the ESH is still limited, and no studies have used this framework with adults. The current investigation aims to examine the association between motor coordination and psychological distress among emerging adults, and examine potential mediators to this relationship based on the ESH. METHODS: 225 young adults aged 17-23 years completed a survey of motor coordination, physical activity, secondary stressors (i.e., general stress and global relationships), perceived social support, self-concept, and psychological distress. Structural equation modeling was conducted to examine mediating pathways and overall model fit. RESULTS: The final model of the ESH showed good model fit (x2 = 83.24, p < .01; RMSEA=0.056; NNFI = 0.927; CFI = 0.954; GFI = 0.947), and indicated that the relationship between poor motor coordination and psychological distress was mediated by secondary stressors, perceived social support, and self-concept. CONCLUSIONS: This study highlights the effect of poor motor coordination on psychological distress in young adults, and suggests that interventions should target psychosocial well-being, in addition to motor coordination, to prevent psychological distress.

RESUMO

Children with low movement proficiency have been identified as having poorer physiological and psychosocial outcomes; however, the varied measurement approaches used to assess these outcomes have varied resulting in conflicting evidence regarding the presence and magnitude of differences compared to Typically Developing (TD) children. Additionally, there has been limited research into the role of parental support for physical activity (PA) in this group. We compared children with varying levels of movement proficiency on physiological characteristics and self-perceptions regarding PA. In addition, these children's parents were compared on physiological characteristics and support of their children's PA. Children (N = 117) aged 6 to 12 years, along with their parent/guardian, participated in this study. Children were classified according to the Movement Assessment Battery for Children-2 test (Typically Developing (TD) = 60; At Risk = 19; Developmental Coordination Disorder (DCD) = 38). Children's PA, muscle strength, cardio-respiratory fitness (CRF), body composition, and self-perceptions regarding PA were assessed, with parents assessed on CRF, body composition, and PA support. Compared to TD children, children with DCD had lower PA (p = 0.036), predilection (p ≤0.001) and adequacy (p ≤0.001) regarding PA, higher body fat percentage (p = 0.019), and received less logistic support (i.e., transportation) from their parents (p = 0.012). TD children had increased muscle strength compared to the DCD (p ≤ 0.001) and At Risk (p ≤ 0.001) groups. Results indicated that, relative to TD children, children with DCD have multiple physiological deficits, receive less parental logistic support for PA involvement, and report lower scores on psychological constructs that are predictive of PA involvement.

RESUMO

BACKGROUND: Although Developmental Coordination Disorder (DCD) is primarily a motor disorder, it can also impact emotional and psychosocial functioning of children with this condition. Evidence suggests that children with DCD experience lower quality of life than their peers, but few studies have explicitly examined the health-related quality of life (HRQOL) of these children. AIMS: To: (1) describe HRQOL of children with DCD compared to typically-developing children; (2) compare HRQOL from the perspectives of children with DCD and their parents; and (3) explore predictors of HRQOL for children with DCD. METHODS: Data from the KidScreen-52 and Strength and Difficulties Questionnaire were collected from 50 children with DCD [Mean(SD) age: 9.8 (1.2) years] and their parents and compared to normative data. RESULTS: Children with DCD and their parents report significantly lower HRQOL compared to published norms. Caregivers have a significantly lower perception of their child's HRQOL than their child's self-report in many domains. Parents of children with DCD report that their children experience significantly more emotional and behavioral disturbances compared to norms. Poor motor function and attentional difficulties predict HRQOL. CONCLUSION AND IMPLICATIONS: DCD appears to contribute to lower perceived HRQOL. Findings inform therapeutic targets for children with DCD, beyond motor skill intervention.

RESUMO

A large proportion of school-aged children exhibit poor drawing and handwriting. This prevalence limits the availability of therapy. We developed an automated method for training improved manual compliance control and relatedly, prospective control of a stylus. The approach included a difficult training task, while providing parametrically modifiable support that enables the children to perform successfully while developing good compliance control. The task was to use a stylus to push a bead along a 3D wire path. Support was provided by making the wire magnetically attractive to the stylus. Support was progressively reduced as 3D tracing performance improved. We report studies that (1) compared performance of Typically Developing (TD) children and children with Developmental Coordination Disorder (DCD), (2) tested training with active versus passive movement, (3) tested progressively reduced versus constant or no support during training, (4) tested children of different ages, (5) tested the transfer of training to a drawing task, (6) tested the specificity of training in respect to the size, shape and dimensionality of figures, and (7) investigated the relevance of the training task to the Beery VMI, an inventory used to diagnose DCD. The findings were as follows. (1) Pre-training performance of TD and DCD children was the same and good with high support but distinct and poor with low support. Support yielded good self-efficacy that motivated training. Post training performance with no support was improved and the same for TD and DCD children. (2) Actively controlled movements were required for improved performance. (3) Progressively reduced support was required for good performance during and after training. (4) Age differences in performance during pre-training were eliminated post-training. (5) Improvements transferred to drawing. (6) There was no evidence of specificity of training in transfer. (7) Disparate Beery scores were reflected in pre-training but not post-training performance. We conclude that the method improves manual compliance control, and more generally, prospective control of movements used in drawing performance.

RESUMO

Developmental coordination disorder (DCD) and attention-deficit hyperactivity disorder (ADHD) are neuro-developmental disorders, starting in childhood, which can affect the planning of movements and the coordination. We investigated how and in which measure a system based on wearable inertial measurement units (IMUs) can provide an objective support to the diagnosis of motor impairments in school-aged children. The IMUs measured linear and rotational movements of 37 schoolchildren, 7-10yo, 17 patients and 20 control subjects, during the execution of motor exercises, performed under medical and psychiatric supervision, to assess different aspects of the motor coordination. The measured motor parameters showed a high degree of significance in discriminating the ADHD/DCD patients from the healthy subjects, pointing out which motor tasks are worth focusing on. So, medical doctors have a novel key lecture to state a diagnosis, gaining in objectivity with respect to the standard procedures which mainly involve subjective human judgment. Differently to other works, we propose a novel approach in terms of number of used IMUs and of performed motor tasks. Moreover, we demonstrate the meaningful parameters to be considered as more discriminant in supporting the medical diagnosis.

RESUMO

BACKGROUND: The Environmental Stress Hypothesis provides a conceptual framework detailing the complex relationship between poor motor skills and internalizing problems. AIMS: This integrative research aimed to synthesize studies that have evaluated complex pathways posited in the framework. METHOD: This study followed the four stages of an integrative research review: (i) problem formation and research aims, (ii) literature search and data collection, (iii) data evaluation and analysis, and (iv) results and discussion. OUTCOMES AND RESULTS: Twelve peer-reviewed, English language studies published within 2010-2018 were identified. These used mostly cross-sectional, correlational methods and provided varying levels of support for relationships posited in the framework in samples spanning early childhood to adulthood. Compared to intrapersonal factors (e.g., self-esteem/ perceived competence), interpersonal factors (e.g., social support, peer problems) were found to more strongly and consistently mediate the relationship between motor skills and internalizing problems. CONCLUSIONS AND IMPLICATIONS: There is growing empirical support for many of the Environmental Stress Hypothesis pathways. However, research to date is limited in the ability to establish causal relationships between variables, which is integral to the Environmental Stress Hypothesis. Intervention studies provide a useful type of experimental research that could establish causality between variables, while working to improve the physical and psychosocial functioning of people with poor motor skills.

RESUMO

The goal of this paper is to analyze a little-known set of documents referring to a "Dancing Epidemic" that took place in Itapagipe, a suburb of Salvador, capital of the province of Bahia, Brazil, in 1882. Through the studies of a group of physicians, especially Raimundo Nina Rodrigues (1862-1906), a psychiatrist and anthropologist from the Bahia School of Medicine, the medical knowledge built on this unique phenomenon in Brazilian history is examined. The case in particular involved a crowd that spread through the streets of Itapagipe, attracting the interest of the medical classes, who were intrigued by the symptoms of motor incoordination the patients manifested. Inspired by foreign literature, but developing their own theories, Rodrigues and colleagues created a unique body of knowledge about the infirmity.

RESUMO

BACKGROUND: Delayed language development without an obvious cause is considered an isolated developmental disorder and is called specific language impairment (SLI). SLI is probably the most prevalent developmental disorder in childhood with a generally cited prevalence of 7%. This study aimed to investigate whether SLI is always an isolated disorder or if children with SLI also have delayed motor development. METHODS: We used data of an earlier study with a prospective nested case-control design in which developmental data were collected from child health care files. Cases were children (4-11 years) with diagnosed SLI. They were matched by sex and date of birth with control children attending mainstream education. Data of both groups on seven gross and six fine motor milestones which had been registered in the Dutch Developmental Instrument between the ages of 15-36 months were retrieved from child health care files. McNemar tests were performed to test for differences in reaching motor milestones at the age norm between the case and control group. RESULTS: Data from 253 children in each group were available. A significant difference was found between both groups in the proportion failing to reach three of the seven investigated gross motor milestones at the age norm (p < 0.05). The proportion of children not reaching the motor milestone at the age norm was significantly higher for five of the six fine motor milestones in children with SLI compared with control children (p < 0.05). CONCLUSIONS: More children with SLI are late in reaching motor milestones than children without SLI. This means that it is debatable whether SLI can be regarded as a "specific" impairment, which is not associated with other developmental problems. A broader developmental assessment is therefore indicated when diagnosing SLI.
