RESUMEN
BACKGROUND: Purpose of this study was to determine what key aspects of function should be incorporated to make up a pre-intervention assessment profile of a child with Developmental Coordination Disorder (DCD); more specifically, what aspects of functioning are implicated in DCD and what is their relative impact? METHODS: A systematic review and meta-analysis were conducted, for which Pubmed, Web of Science, Scopus and Proquest were searched (last update: April 2023, PROSPERO: CRD42023461619). Case-control studies were included to determine point estimates for performances on field-based tests in different domains of functioning. Risk of bias was assessed, and level of evidence estimated. Random-effect meta-analyses were performed to calculate the pooled standardized mean differences for domains of functioning and subgrouping was done for clinically relevant subdomains. Heterogeneity was determined with I2. RESULTS: 121 papers were included for analyses. Data of 5 923 children with DCD were included (59.8% boys) and 23 619 Typically Developing (TD) children (45.8% boys). The mean (SD) age of the DCD group was 10.3y (1.2) and 9.3y (1.3) for the TD children. Moderate evidence was found for motor performance, executive functions, sensory processing and perceptions, cognitive functions and sports and leisure activities to be affected in children with DCD. CONCLUSION: Differences between the two groups varied per domain of functioning. This emphasizes the diversity present within children with DCD and provides a rationale for explaining the heterogeneity in this patient group. Yet, results highlight the potential involvement of all these domains and call for clinicians to be alert not only to examine motor skill difficulties but also other aspects of function. Results indicate the need to develop an individualized pre-intervention multi-dimensional assessment profile for each child with DCD. It also supports the important role that clinicians play in an interdisciplinary team to tackle the difficulties encountered by children with DCD.
RESUMEN
BACKGROUND: Generalized Joint hypermobility (GJH) is predominantly non-symptomatic. In fact, individuals with joint flexibility usually perform better than their non-hypermobile counterparts during physical activities. Notwithstanding, strength and balance are essential to maintain the control of the extra range of motion during activities and to prevent musculoskeletal complications. There are limited and conflicting pieces of evidence in literature regarding the association between strength and balance in children with GJH. OBJECTIVES: The purpose of this study was to examine differences in functional strength, dynamic balance, proprioception, and isometric strength in children with and without joint hypermobility and determine the association between strength outcomes and dynamic balance. METHOD: A cross-sectional study was conducted among children aged 6 to 11. Hypermobility was determined using the Beighton Score, with scores ≥6 representing hypermobility. Functional strength was assessed with the Functional Strength Measure (FSM), isometric strength was determined with a handheld dynamometer (HHD), the Y-Balance Test (YBT) was used to assess dynamic balance and the Wedges test to measure proprioception. RESULTS: This study included 588 participants (age: 7.97 ± 1.3 years; height: 128±10.1 cm; mass: 27.18 ± 7.98 kg). 402 children were classified as having normal mobility and 186 as being hypermobile. Hypermobile children had better functional strength in the lower extremities than children with normal range mobility but lower reach distance in the YBT. No differences in proprioception, functional strength of the upper extremity or isometric strength in the hands were found. However, isometric lower extremity force was less in hypermobile children than children with normal range mobility. Irrespective of their joint mobility, a fair significant correlation existed between total Y-balance distance and FSM items r = 0.16-0.37, p = 0.01. Correlations between total Y-balance distance and isometric strength of knee and ankle muscles ranged between r = 0.26-0.42, p = 0.001. CONCLUSION: Hypermobile joints seem to co-occur with lower extremity isometric strength, more functional strength in the lower extremities and less reaching distance in dynamic balance. The opposing direction of the results on functional and isometric strength tests highlights the importance of the type of outcome measures used to describe the association of strength and the range of motion.

The present study aimed to examine precision and variability in dart throwing performance and the relationships between these outcomes and bouncing, throwing and catching tasks in children with and without DCD. Children between the ages of 8 and 10 years (n = 165) were classified according to results obtained on the Movement Assessment Battery for Children (MABC-2) and divided into three groups: 65 children with severe DCD (s-DCD), 45 with moderate DCD (m-DCD) and 55 typically developing children (TD). All children performed the dart throwing test and the ball skill items of the Performance and Fitness Test (PERF-FIT). The accuracy and variability of dart throwing tasks were significantly different between TD and s-DCD (p < 0.01), and also between m-DCD and s-DCD (p < 0.01). Participants with s-DCD were also found to perform significantly worse on all PERF-FIT ball skill items than m-DCD (p < 0.001), and m-DCD were significantly poorer than TD (p < 0.001). The dart score and coefficient of variation of the long-distance task appear to be significant predictors for the ball skills and explain between 24 to 29% of their variance. In conclusion, poor results in aiming tasks using darts in children with DCD corroborate with the explanation of deficits in predictive control since the tasks require ballistic movements.
RESUMEN
BACKGROUND: Children with Developmental Coordination Disorder (DCD) are diagnosed based on poor motor skills that impact their daily activities. However, this may also lead to lower predilection and participation in physical activities and a higher risk to develop health problems. OBJECTIVE: To determine motor skill related levels in children with moderate and severe DCD and compare that to typically developing children (TD). The study also aimed to determine the level of activities of daily living (ADL) as reported by their parent and self-efficacy as reported by the children. Lastly, the relation of motor skill related fitness, ADL, and self-efficacy has been examined. METHODS: A cross-sectional study has compared TD children (n = 105) and children with DCD (n = 109; 45 moderate DCD and 64 severe DCD) from elementary schools in Tunisia between 7 and 10 years of age. The DCDDaily-Questionnaire and Children's Self-perceptions of Adequacy in and Predilection for Physical Activity Questionnaire have been used to determine ADL and adequacy towards physical activity, respectively. The PERF-FIT has been used to measure motor skill related fitness levels. RESULTS: Large group differences (p = 0.001) were found for ADL and all domains of self-efficacy between TD and DCD children. However, ADL and self-efficacy were not different between moderate and severe DCD. Motor skill related fitness was significantly lower (p = 0.01) for children with DCD than TD children, and between children with moderate and severe DCD. The relation between self-efficacy and DCDDaily-Q was different in the two DCD groups. Slow motor learning was associated with lower perceived enjoyment in physical education in the moderate DCD group, and with lower perceived adequacy in physical education in the severe DCD group. CONCLUSIONS: Children with DCD participate and enjoy physical activity less than their peers. This combination of lower participation, lower predilection to physical activity and lowered motor skill-related fitness is a concern for the present and future health status of children with DCD.

The present paper is designed to promote awareness of DCD outside the academic world. With a prevalence of 5-6% it is one of the most common disorders of child development. It is therefore surprising that so little is known about it among professionals in child healthcare and education. Parents have expressed frustration about this lack of awareness, including the general public. The general aim of this paper was to describe those critical aspects of DCD that will promote awareness.

Active video games (AVG) have been used as training tools and are known to ameliorate balance performance in children with Developmental Coordination Disorder (DCD). Our aim was to evaluate balance using clinical tests and by measuring body sway using a force plate with a mixed design of vision (eyes open/eyes closed), surface (rigid/soft), and support (stance/semitandem) before, and after, training and 4 months later (follow-up). Thirty-six DCD children and 40 typically developing children participated in the study, of which 50 children (26 DCD; 24 typically developing) were retested after 4 months. Balance improved on the clinical measures after the training, which was independent of type of AVG (Wii-Fit and Xbox Kinect) used, and this effect was still present after 4 months. The AVG training did not influence general sway behavior, but only sway in the eyes-open condition, corresponding with task demands of the training and indicating a training-specific effect. Overall, DCD children and typically developing children responded comparably to the AVG training, thereby maintaining the gap in performance between the two groups. The changes in postural sway are interpreted as a sign of more confidence and less freezing of the joints, enabling greater flexibility of movements and balance strategies as supported by the improved performance on balance tests in the DCD children. This is the first study that showed long-term effects of AVG training on balance performance. However, these follow-up results should be interpreted with caution given that 35% of the children were lost in follow-up.

BACKGROUND: People with Parkinson's disease (PwP) often report problems with their handwriting before they receive a formal diagnosis. Many PwP suffer from deteriorating handwriting throughout their illness, which has detrimental effects on many aspects of their quality of life. AIMS: To assess a 6-week online training programme aimed at improving handwriting of PwP. METHODS: Handwriting samples from a community-based cohort of PwP (n = 48) were analysed using systematic detection of writing problems (SOS-PD) by two independent raters, before and after a 6-week remotely monitored physiotherapy-led training programme. Inter-rater variability on multiple measures of handwriting quality was analysed. The handwriting data was analysed using pre-/post-design in the same individuals. Multiple aspects of the handwriting samples were assessed, including writing fluency, transitions between letters, regularity in letter size, word spacing, and straightness of lines. RESULTS: Analysis of inter-rater reliability showed high agreement for total handwriting scores and letter size, as well as speed and legibility scores, whereas there were mixed levels of inter-rater reliability for other handwriting measures. Overall handwriting quality (p = 0.001) and legibility (p = 0.009) significantly improved, while letter size (p = 0.012), fluency (p = 0.001), regularity of letter size (p = 0.009), and straightness of lines (p = 0.036) were also enhanced. CONCLUSIONS: The results of this study show that this 6-week intensive remotely-monitored physiotherapy-led handwriting programme improved handwriting in PwP. This is the first study of its kind to use this tool remotely, and it demonstrated that the SOS-PD is reliable for measuring handwriting in PwP.

PURPOSE: This study aimed to determine the relationship between kinaesthesia, motor performance, fitness, and joint mobility in children. METHODS: A descriptive cross-sectional study was conducted involving children from two primary schools in the South-Eastern part of Nigeria. The Beighton criteria were used to measure joint mobility. Motor performance, fitness, and kinaesthesia were measured in all the children. Spearman's rank correlation was used to evaluate the relationship between the outcomes. RESULTS: A total of 91 children (51.6% girls) participated in the study. The mean age of the children was 8.20 ± 1.98 years. Using a Beighton score of ≥ 6, Generalized Joint Hypermobility (GJH) was identified in a total of 35 (38.46%) children and was more prevalent in females (60.0%). Joint mobility had significant correlations with most fitness and motor performance items, but not kinaesthesia. Agility & power, and motor performance seem to be reduced if mobility is larger. Kinaesthesia was correlated with most fitness and motor performance items, indicating that better fitness and better motor performance cooccur with better kinaesthesia or vice versa. CONCLUSION: Joint mobility may have a significant influence on fitness and motor performance in children. Hence, it may be useful for future studies to investigate how fitness and motor performance modulate the onset and progression of musculoskeletal symptoms in GJH.

This study aims to investigate sex-related differences in raw item scores on the Movement Assessment Battery for Children, 2nd Edition (MABC-2) in a large data set collected in different regions across the world, seeking to unravel whether there is an interaction effect between sex and the origin of the sample (European versus African). In this retrospective study, a secondary analysis was performed on anonymized data of 7654 children with a mean age of 8.6 (range 3 to 16; SD: 3.4), 50.0% of whom were boys. Since country-specific norms were not available for all samples, the raw scores per age band (AB) were used for analysis. Our results clearly show that in all age bands sex-related differences are present. In AB1 and AB2, girls score better on most manual dexterity and balance items, but not aiming and catching items, whereas in AB3 the differences seem to diminish. Especially in the European sample, girls outperform boys in manual dexterity and balance items, whereas in the African sample these differences are less marked. In conclusion, separate norms for boys and girls are needed in addition to separate norms for geographical regions.
RESUMEN
BACKGROUND: Children with Developmental Coordination Disorder (DCD) face difficulties in motor learning. Action observation and imitation are strategies frequently used to teach motor skills. AIMS: (1) To study action observation and imitation abilities in children with DCD compared with typically developing peers with a new protocol. (2) To gain insights in the relation between action observation, imitation, motor performance and activities of daily living (ADL). METHOD: Twenty-one children with DCD (mean age 7 years 9 months, range 6-10 years) and 20 age-matched controls (mean age 7 years 8 months, range 6-10 years) were included. A newly developed protocol was used for testing action observation and imitation proficiency. Motor performance were evaluated with the Movement Assessment Battery for Children-2. ADL were investigated with DCD Questionnaire'07. RESULTS: Children with DCD presented significantly lower action observation (p = .037) and imitation abilities (p < .001) than peers. Worse action observation and imitation abilities were related to lower motor performance and ADL skills and a younger age. Non-meaningful gestures imitation proficiency had predictive value for global motor performance (p = .009), manual dexterity (p = .02) and ADL (p = .004). CONCLUSIONS: The new protocol for action observation and imitation abilities can be helpful for detecting motor learning difficulties and for delineating new opportunities for motor teaching approaches in children with DCD.

BACKGROUND: The purpose of this study was to determine the prevalence of hypermobility in randomly selected healthy children, without previous trauma or disease process affecting the joints and whether other demographic variables (age, sex, BMI) had an impact on Beighton scores and range of motion (RoM) in children between 6 and 10 years of age. RESULTS: 286 children were included; 27.3% of them had a Beighton score ≥7/9 and 72% would be classified hypermobile if we had used a Beighton cut-off score ≥4/9. Prevalence declined with increasing age. Girls were more often hypermobile (34%) than boys (20%) and this was mainly caused by increased RoM in the knees. Positive scores of finger items of the Beighton were more common than on the other items, leading to a high prevalence of peripheral hypermobility. Localized hypermobility was only found in the fifth MCP joint. A total of 15% of the children with normal mobility reached 20 excess degrees RoM of the left and right fifth MCP. Pain was present in 12 of the 239 children but was not linked to the level of mobility. CONCLUSION: Hypermobility is the rule in this pain-free population of children with GJH.
RESUMEN
BACKGROUND: Besides motor coordination problems, attentional impairments are reported in children with developmental coordination disorder (DCD), but the connection or trainability is still unclear. AIM: To test changes on attentional abilities after playing active video games (AVG) in children with DCD and their peers (TD), to evaluate near transfer and the relationship between omissions in attentional and motor tests. METHODS: Seventy children (35 DCD; 35 TD), 7-12 years old, were assessed on three types of attention: distractibility (DIS); divided-attention (DA); sustained-attention (SA) and on the Wii Fit test pre- and post-training. RESULTS: A significant decrease of errors in attentional tasks was found after training, independent of group (TD/DCD) and console (Wii Fit/Xbox) with medium-strong effect sizes (DIS η2p =.42; DA η2p =.51; SA η2p =.41). The groups responded similarly to the training but the DCD children scored poorer on the DA. A positive transfer-effect to the non-trained Wii Fit test was found in accuracy (missed gates), while speed proved console-specific. A medium/strong relation was found between omissions in attentional tasks and the missed gates (Wii Fit test). CONCLUSION: More accurate responses on attentional tasks were found after AVG-training in both groups. A clear relationship between attentional abilities and motor performance was found.
RESUMEN
BACKGROUND: Task-oriented approaches are recommended for children with developmental coordination disorder (DCD) to address deficits in motor performance and reduce activity limitations. Although this approach is used in several settings, the efficacy of these approaches in children with in dual-diagnosis of specific learning disabilities (SLD) and DCD is less widely known. This study aims to determine the effect of a group-based intervention based on neuromotor task training (NTT) principles on the motor performance of children aged 6-10 years with SLD/DCD. METHODS: A pre-post-test controlled study design was conducted in children with a primary diagnosis of specific learning disabilities (SLD). DCD status was confirmed based on clinical assessment. Children scoring ≤16th percentile on the Motor Assessment Battery for Children 2nd Edition (MABC-2), who also presented with a functional motor problem, according to the MABC checklist were considered as having DCD. Children were allocated to the NTT intervention group based on teachers' perceived notion of need and received two 45-60 min training sessions per week for nine weeks. Children allocated to the usual care (UC) group, received their planned occupational therapy and physical education. The MABC-2 was used to assess changes in motor performance. OUTCOME AND RESULTS: Our numbers confirm that it is crucial to identify the presence of motor coordination difficulties in children who have been diagnosed with SLD. A task-oriented training program based on NTT principles, presented in small groups, has a positive effect on the motor performance in learners with neurodevelopmental disorders and this effect was larger than in the usual care group. CONCLUSION AND IMPLICATIONS: Although using a small group format in children with multiple neurodevelopmental disorders may be challenging for the therapists, it may be a way of delivering services to children in schools for special education. WHAT THIS PAPER ADDS: Children with DCD plus LSD show improvement in their motor skills by performing group-based NTT in the school environment. Group-based NTT shows a significant improvement in the TSS score of the MABC-2 compared to usual care. Children with DCD plus SLD show equal effect sizes after NTT intervention as DCD without SLD.
RESUMEN
OBJECTIVE: To map the effect of motor-based interventions on motor skills in children with ADHD. METHOD: A systematic literature search was performed in Pubmed, Web of Science, and the SCOPUS database (last search: October 30th 2022). Methodological quality was assessed using the PEDro-scale and the quality of evidence was determined with the GRADE-method. Meta-analysis was performed when at least five studies were available. RESULTS: Thirteen studies (7 RCTs) satisfied the inclusion criteria, five of which were eligible for meta-analysis. Only one of the included studies reached the low risk of bias threshold. Comparing different motor-based interventions to any non-motor control intervention showed large motor skill improvements (SMD = 1.46; 95% CI = [1.00;1.93]; I² = 47.07%). The most effective type of motor-based intervention and the optimal treatment parameters could not be determined yet. CONCLUSION: Motor-based interventions in general seem to improve motor skills in children with ADHD. Additional RCTs are needed to increase current low GRADE confidence.

AIM: To compare the effects of two Active Video Game (AVG) protocols on transfer of learning in children with and without Developmental Coordination Disorder (DCD). METHODS: Fifty children, aged 6-10 years were randomly allocated to either group A or B. Children in group A participated in a set of Nintendo Wii ball games whereas group B played agility games (8 DCD and 17 typically developing children (TD) per group). Participants in each group practiced Wii games for 20 min twice a week for 10 weeks. All children also practiced ball and agility games in real-world settings, once per week. RESULTS: Both protocols yielded positive effects with the largest effect sizes shown on agility and balance items of the PERF-FIT and KTK tests. No interaction was found on learning real-world games and the virtual protocol, except for a Ping-Pong game. A significant interaction of time by protocol group indicated that the Ball group improved more on BOT-2-Upper-Limb Coordination than the Agility group. Importantly, children with DCD improved comparably with TD peers in virtual and real-world games. CONCLUSION: Independent of training protocol, both children with DCD and TD children performed better on trained and non-trained ball, balance and agility tasks after 10 weeks of training.

AIM: To compare the effect of the Nintendo Wii-Fit and Xbox Kinect on motor performance and to assess differential effects in children with Developmental Coordination Disorder (DCD) and typical development (TD). METHOD: In an assessor-blinded randomized comparator-controlled design, 68 participants (34 DCD and 34 TD) aged 7-10 years, were randomly assigned to train on one of two devices (34 Wii-Fit; 34 Xbox Kinect). RESULTS: Repeated measure ANOVA revealed a significant main effect of time on balance and agility variables (MABC-2, Wii Yoga stance, PERF-FIT side-hop, PERF-FIT ladder-stepping; all p ≤ 0.02), but not on running variables (BOT2-sprint, 10 × 5 m sprint and PERF-FIT ladder running; p > 0.05). No significant interactions were observed, indicating similar changes on both devices. Overall, 35% of the TD children and 76% of the children with DCD improved on one or more of the outcomes beyond the smallest detectable difference. However, at the individual level, larger differences in improvement were found in the Kinect group compared to the Wii between TD and DCD groups. CONCLUSION: Both Wii-Fit and Kinect devices can be used to train with similar results on motor performance. An important percentage (76%) of children with DCD improved on at least one motor task after training.

Background: Injury risk is high in Physical Education Teacher Education (PETE) students. Insights into specific injury locations per sex, setting, sports, and curriculum year are needed to develop preventive measures. Purpose: To compare injury distributions by body locations in PETE students and how these distributions differ by sex, type, onset, curriculum year, settings, or sports. Methods: In a historical cohort study over 14 years, data from 2899 students (male 76.2%, n = 1947) enlisted in the first three years of a PETE curriculum were analysed. Injuries reported at the institution's medical facility were categorised per sex, body location, onset, type, setting, sports, and curriculum year. Results: Forty-three percent (n = 1247) of all students (female 54.9%, n = 523, male 37.2%, and n = 429) reported a total of 2129 injuries (freshmen 56.4%; 2nd year 28.2%; 3rd year 15.5%). The most prevalent sudden onset injury locations (63.4% of all injuries) were the ankle (32.5%) and knee (16.6). The most prevalent gradual onset injuries were the lower leg (27.8%) and knee (25.2%). Joint/ligament injuries (45.8%) and muscle/tendon injuries (23.4%) were the most prevalent injury types. Proportions for injury locations and injury types differed significantly between curriculum years. Injury prevalence per setting and sport differed significantly between the sexes. Injury locations differed significantly between sports and between the sexes per sport. Conclusion: A differential approach per injury location, onset, type, sex, setting, sports, and curriculum year is needed to develop adequate preventive measures in PETE studies. The engagement of precurricular, intracurricular, and extracurricular stakeholders is needed in the development of these measures.
RESUMEN
Our objective was to compare changes in game performance and intensity of heart rate (HR) between two types of active video game (AVG) in children with and without Developmental Coordination Disorder (DCD). Additionally, we assessed the level of improvement per game as well as the perceived exertion and enjoyment during training. Seventy-six children, 36 with DCD and 40 without (TD) were randomly assigned to a 5-week program of Wii-Fit or Xbox-Kinect training 2× a week. The steepness of the performance curves was not different between consoles, nor between groups. Playing Kinect games resulted in higher HR in both groups. Wii and Kinect seem to be comparable AVG consoles that can be used for children with and without DCD, with the Kinect reaching a higher intensity of training.
RESUMEN
Given the knowledge gap in literature on the impact of undernutrition on muscular power and agility in school-aged children, the aim of this study was to compare physical fitness in such underweight- and normal weight children. In this cross-sectional study, 853 children were included (459 boys; mean age: 9.2 (1.8) years). The children were grouped according to their BMI-for-age-and-sex: normal weight (- 1 ≤ z-score < 2) and underweight (z-score < - 1). Within the underweight group, three thinness subgroups were composed: grade 1 (- 2 ≤ z-score < - 1), grade 2 (- 3 ≤ z-score < - 2) and grade 3 (z-score < - 3). Their agility, muscular endurance and power were assessed with the Performance and Fitness test battery (PERF-FIT). Regardless the country they lived in, the underweight children showed better agility (p = 0.012) and muscular endurance (p = 0.004) than those with normal weight. They presented with lower muscular power than the normal weight group, shown by significantly shorter overhead throwing distances (p = 0.017) and less standing long jump peak power (p < 0.001). The standing long jump peak power decreased further with increasing thinness grade (p = 0.027).Conclusion: Underweight children are more agile, but have lower muscular power compared to their normal weight peers. Its relationship with motor competence and physical activity, necessitates attention for tackling muscular strength deficiencies in these children, enabling them to meet the basic requirements for a healthy lifestyle later in life.
