The present study aimed to clarify the development of motor unit (MU) firing properties and the association between those neural properties and force steadiness (FS)/neurological tests in 6- to 12-year-old children. Fifty-eight school-aged children performed maximal voluntary knee extension contraction, a submaximal FS test at 10% of maximal voluntary knee extension contraction, knee extension reaction time to light stimulus test, and single-leg standing test, and data from 38 children who passed the criteria were subject to analysis. During the FS test, high-density surface electromyography was recorded from the vastus lateralis muscle to identify individual MU firing activity. FS was improved with an increase in age (r = −.540, P <.001). The MU firing rate (MUFR) was significantly decreased with an increase in age (r = −.343, P =.035). MUFR variability was not associated with age. Although there was no significant correlation between FS and MUFR, FS was significantly correlated with MUFR variability even after adjustment for the effect of age (r =.551, P =.002). Neither the reaction time nor the single-leg standing test was correlated with any MU firing properties. These findings suggest that MUFR variability makes an important contribution to precise force control in children but does not naturally develop with age. [ABSTRACT FROM AUTHOR]

The current study examined the acquisition, retention, and transfer effects of a motor program. Children with autism spectrum disorder participated in a 9-week program that targeted 13 fundamental motor skills based upon the Test of Gross Motor Development-3. Assessments were conducted before and after the program, as well as at 2-month follow-up. Significant improvements were found on not only the trained fundamental motor skills (acquisition) but also the untrained tasks on balance (transfer). The follow-up tests revealed continuous improvement on the trained locomotor skills (retention), as well as the untrained skills on balance (retention + transfer). These findings highlight the importance of continuous support and long-term participation on motor practices. [ABSTRACT FROM AUTHOR]

Visual supports have been advocated as one strategy to teach children with autism in physical education. However, empirical studies documented inconsistencies in their effectiveness, with some demonstrating positive effects while others reported limited support for their use. Without a clear synthesis of information, physical educators may have difficulties in identifying and meaningfully utilizing visual supports. A systematic literature review on visual supports was conducted with synthesized current literature for physical educators to make informed decisions regarding their use for children with autism in physical education. A total of 27 articles were reviewed, which included empirical- and narrative-based manuscripts. Results suggest that picture task cards, visual activity schedules, and video prompting can be potential strategies that physical educators can use to teach motor skills to children on the spectrum. However, video modeling may need to be further investigated to fully understand how to use it in the context of physical education. [ABSTRACT FROM AUTHOR]

Aims: To examine physical functions, activity, and participation level, and associated factors with participation in children with juvenile idiopathic arthritis (JIA) across the International Classification of Functioning Disability and Health-Children and Youth. Methods: 49 children (Girl/Boy:28/21) aged between 7 and 18 years (Mean: 13.4 ± 3.3) were included. To evaluate body structure/functioning; pain, fatigue, disease activity, and motor functions were assessed. Childhood Health Assessment Questionnaire and Juvenile Arthritis Biopsychosocial and Clinical Questionnaire were used to determine activity level. Child and Adolescent Scale of Participation was used to assess participation. Results: Mild level of pain (2.0 ± 2.3), disease activity (2.0 ± 2.3), and fatigue (4.1 ± 4.0) were recorded. Decrease in motor functions was determined in 75% of children, while 61% of whom had activity-related disability. There was mild to moderate participation restrictions, and participation was significantly associated with age (r = –0.29), pain severity (r = –0.31), disease activity (r = –0.39), motor functions (r = 0.33), and activity level (r = –0.43), (p ˂ 0.05). Conclusions: Majority of children with JIA have deteriorations in physical functions, activity, and participation. Age, pain, disease activity, motor functions and activity level were associated with participation level. Children with JIA should be regularly evaluated multi-directional and they should be referred to rehabilitation programs to increase functionality and participation. [ABSTRACT FROM AUTHOR]

Aim: Our study investigates the feasibility and utility of implementing a dual joystick-operated ride-on-toy navigation training (RNT) program within a 3-week intensive camp based on principles of modified constraint-induced movement therapy and bimanual training, to improve upper extremity (UE) function in children with unilateral cerebral palsy (UCP). Methods: We employed a single-group pretest posttest, mixed methods study design. Eleven 4-to-10-year-old children with UCP received RNT as part of camp activities. Sessions required children to use both arms together for navigation and completing gross and fine motor UE challenges. We collected exit questionnaires from children, caregivers, and clinicians to assess the feasibility, acceptance, enjoyment, and perceived efficacy of RNT. Videos of training sessions were coded using Datavyu behavioral coding software to assess children's facial expressions and affective states, indicative of their level of engagement during intervention sessions. Results: We found high levels of child engagement during RNT sessions based on video data and stakeholder feedback. The RNT program was smoothly integrated into the camp. Stakeholders acknowledged the highly motivating nature of RNT. When combined with other camp activities, the program led to stakeholder-reported improvements in bimanual skills and spontaneous daily use of the affected UE. Conclusions: Our pilot study provides promising evidence for using joystick-operated ride-on toys as engaging therapy adjuncts. Our findings call for future studies to systematically assess the efficacy of these devices in improving UE function among children with UCP. [ABSTRACT FROM AUTHOR]

Purpose: An internal model deficit is considered to underlie developmental coordination disorder (DCD); thus, children with DCD have an altered sense of agency (SoA), which is associated with depressive symptoms. Furthermore, the perception of action-outcome regularity is present in early development, is involved in the generation of SoA, and has roles in adaptive motor learning and coordinated motor skills. However, perceptual sensitivity to action-outcome regularity has not been examined in children with DCD. Methods: We investigated perceptual sensitivity to action-outcome regularity in 6–15-year-old children with DCD and age- and sex-matched typically developing (TD) children. Both groups were assessed for coordinated motor skills with the Movement Assessment Battery for Children-2nd Edition, while the DCD group was assessed with the DCD Questionnaire, Social Communication Questionnaire, Attention-Deficit/Hyperactivity Disorder-Rating Scale, and Depression Self- Rating Scale for Children. Results: Perceptual sensitivity to action-outcome regularity was significantly reduced in children with DCD. However, there was a significant correlation between perceptual sensitivity to action-outcome regularity and age in DCD and TD children. Perceptual sensitivity to action-outcome regularity was significantly lower in younger children with DCD than in younger and older TD children, but there were no significant differences between older children with DCD and younger and older TD children. Conclusion: The current results suggest that children with DCD have significantly reduced perceptual sensitivity to action-outcome regularity at younger ages, which may alter SoA and inhibit internal model development, thereby reducing motor skill coordination.

Background: Individuals (i.e. children/young adults) with developmental disabilities (DDs) and intellectual disabilities (IDs) often display a variety of physical and motor impairments. It is well known that participation in motor activities can positively impact the development of children's cognitive and social skills. Recently, virtual and digital technologies (e.g. video conferencing applications, virtual reality and video gaming) have been increasingly used to promote better physical/motor outcomes. The efficacy of digital technologies in improving motor outcomes for those with DD/ID varies depending on the technology and population, and the comparative effects of various technologies are unknown. The aim of our study is to conduct a systematic review to comprehensively examine the quantitative and qualitative results of current studies reporting the efficacy of digitally based motor interventions on motor outcomes in individuals with DD/ID. Methods: Literature published from 1900 to 2024 was searched in four health sciences databases: PubMed, PsycINFO, Scopus and CINAHL. Articles that examined the effects of gross motor/physical activity training using technologies such as exergaming (i.e. exercise through video gaming such as the Wii and Xbox Kinect), virtual reality or telehealth video conferencing applications (i.e. Zoom, Webex or mobile health apps) on the standardised or game‐specific gross motor performance of individuals with DD/ID diagnoses that do not typically experience significant walking challenges using experimental or quasi‐experimental study designs were included. Thirty relevant articles were retrieved from a search of the databases PubMed (914), PsycINFO (1201), Scopus (1910) and CINAHL (948). Results: Our quantitative synthesis of this published literature suggests strong and consistent evidence of small‐to‐large improvements in motor skill performance following digital movement interventions. Conclusions: Our review supports the use of digital motor interventions to support motor skill performance in individuals with DD without ID. Digital technologies can provide a more engaging option for therapists to promote motor skill development in individuals with DD or for caregivers to use as an adjunct to skilled therapy.

Introduction: In spite of rapid advances in evidence-based treatments for attention deficit hyperactivity disorder (ADHD), community access to rigorous gold-standard diagnostic assessments has lagged far behind due to barriers such as the costs and limited availability of comprehensive diagnostic evaluations. Digital assessment of attention and behavior has the potential to lead to scalable approaches that could be used to screen large numbers of children and/or increase access to highquality, scalable diagnostic evaluations, especially if designed using user-centered participatory and ability-based frameworks. Current research on assessment has begun to take a user-centered approach by actively involving participants to ensure the development of assessments that meet the needs of users (e.g., clinicians, teachers, patients). Methods: The objective of this mapping review was to identify and categorize digital mental health assessments designed to aid in the initial diagnosis of ADHD as well as ongoing monitoring of symptoms following diagnosis. Results: Results suggested that the assessment tools currently described in the literature target both cognition and motor behaviors. These assessments were conducted using a variety of technological platforms, including telemedicine, wearables/sensors, the web, virtual reality, serious games, robots, and computer applications/software. Discussion: Although it is evident that there is growing interest in the design of digital assessment tools, research involving tools with the potential for widespread deployment is still in the early stages of development. As these and other tools are developed and evaluated, it is critical that researchers engage patients and key stakeholders early in the design process. [ABSTRACT FROM AUTHOR]

Introduction: This study explored the extent to which an interactive computer play system, Bootle Blast, supports motor learning in a clinical context and examined clinicians' perceptions of their therapeutic role in the system's use as an intervention tool. Methods: In this observational sequential explanatory mixed methods study, five children with cerebral palsy [mean age 9.4 years (SD, 0.5), Gross Motor Function Classification System Levels I-III] used Bootle Blast during a single videorecorded therapy session with their treating clinicians (physical therapists, occupational therapists, and therapy assistants). Children played one Bootle Blast mini game independently (without clinician involvement) before clinicians carried out therapy sessions with the game as per usual care. The type and extent of motor learning strategies (MLS) delivered by Bootle Blast and clinicians were rated from video recordings by a trained assessor using the 22-item Motor Learning Strategies Rating Instrument. Semi-structured interviews with clinicians were conducted to gain insights into MLS use and clinicians' perceived role during Bootle Blast use. Interviews were audio recorded, transcribed verbatim, and analyzed independently by two researchers using thematic analysis. Quantitative and qualitative data were merged and reported using narrative and joint display approaches. Results: Bootle Blast provided eight MLS, with clinicians adding or enhancing another eight. Four themes reflected clinicians' perspectives: (1) Bootle Blast disguises therapy as play, (2) clinicians give Bootle Blast the human touch; (3) home use of Bootle Blast is promising; and (4) Bootle Blast is not always the right fit but some shortcomings could be addressed. Agreement was found for nine MLS and disagreement for four MLS when quantitative and qualitative findings were merged. Discussion: Bootle Blast delivers several MLS as part of game play and clinicians can enhance and provide additional MLS to suit the child's needs/abilities. Further game refinements that were identified in this study may optimize its clinical use. [ABSTRACT FROM AUTHOR]

Cerebral palsy (CP) is a leading cause of long-term disability in children worldwide where severe cases may require complete dependence on caregivers for mobility, self-care, and social participation. The demand for caregiving may negatively impact the level of life satisfaction of the caregivers, especially the mothers. This study was thus carried out to evaluate the level of life satisfaction of mothers of children with CP, its association with perceived social support, and the motor function of their children. Method: The study involved 58 mothers of children with CP and their children. The level of life satisfaction, perceived social support, and socioeconomic status of the mothers were assessed using the satisfaction with life scale, the multidimensional scale of perceived social support, and the modified Kuppuswamy Socioeconomic Scale, respectively. The motor function of the children with CP was assessed using the Gross Motor Function Classification System (GMFCS). Result: About 38% of the mothers of children with cerebral palsy were fully satisfied with their lives. There was no significant association among the level of life satisfaction, perceived social support of mothers of children with CP, and the motor function of their children. Conclusion: Six out of ten mothers of children with cerebral palsy are somewhat dissatisfied with life. It was recommended that measures to relieve factors leading to dissatisfaction with life should be put in place by national health policymakers. [ABSTRACT FROM AUTHOR]

Young autistic children and their siblings often need support to play and engage with each other. The inclusion of older siblings in the provision of support may improve outcomes for autistic children and strengthen the sibling relationship. This study evaluated the inclusion of older siblings in the delivery of Early Start Denver Model (ESDM) support to autistic children aged between 3 and 4 years. It used a non-concurrent multiple baseline across participants design to evaluate the effects of sibling-mediated ESDM for four young autistic children and their older, non-autistic siblings. For most dyads, there were improvements in autistic child engagement and in sibling initiations during the sibling-mediated ESDM, which were generally maintained at follow-up. There was some improvement in sibling responses and minimal improvement in autistic child imitation and functional utterances. Sibling initiations and responses were generally positively correlated with autistic child engagement, functional utterances, and imitation. The parents of children in all four dyads found the sibling-mediated ESDM to be acceptable. These preliminary results suggest that sibling-mediated ESDM may be beneficial for improving the interaction between autistic children and their non-autistic siblings while benefits for teaching additional child skills might be more limited. Highlights: Young autistic children and their older siblings could benefit from structured support during play. We examined sibling-mediated ESDM for four young autistic children and their older, non-autistic siblings. The sibling-mediated support led to improvements in autistic child engagement and in sibling initiations. There were some improvements in sibling responses to the autistic child. There were minimal improvements in autistic child functional utterances and imitation of their sibling. [ABSTRACT FROM AUTHOR]

Background: Children with speech sound disorders (SSD) form a heterogeneous group, with respect to severity, etiology, proximal causes, speech error characteristics, and response to treatment. Infants develop speech and language in interaction with neurological maturation and general perceptual, motoric, and cognitive skills in a social-emotional context. Purpose: After a brief introduction into psycholinguistic models of speech production and levels of causation, in this review article, we present an in-depth overview of mechanisms and processes, and the dynamics thereof, which are crucial in typical speech development. These basic mechanisms and processes are: (a) neurophysiological motor refinement, that is, the maturational articulatory mechanisms that drive babbling and the more differentiated production of larger speech patterns; (b) sensorimotor integration, which forms the steering function from phonetics to phonology; and (c) motor hierarchy and articulatory phonology describing the gestural organization of syllables, which underlie fluent speech production. These dynamics have consequences for the diagnosis and further analysis of SSD in children. We argue that current diagnostic classification systems do not do justice to the multilevel, multifactorial, and interactive character of the underlying mechanisms and processes. This is illustrated by a recent Dutch study yielding distinct performance profiles among children with SSD, which allows for a dimensional interpretation of underlying processing deficits. Conclusions: Analyses of mainstream treatments with respect to the treatment goals and the speech mechanisms addressed show that treatment programs are quite transparent in their aims and approach and how they contribute to remediating specific deficits or mechanisms. Recent studies into clinical reasoning reveal that the clinical challenge for speech-language pathologists is how to select the most appropriate treatment at the most appropriate time for each individual child with SSD. We argue that a process-oriented approach has merits as compared to categorical diagnostics as a toolbox to aid in the interpretation of the speech profile in terms of underlying deficits and to connect these to a specific intervention approach and treatment target.

Purpose: This study aimed to analyze the shared genetic background of physical fitness tests in children. Methods: Physical fitness was assessed in 198 Portuguese twin pairs (6–18 yr old, 40% monozygotic) through 15 tests from the Eurofit and Fitnessgram test batteries. Genetic twin modeling was used to estimate the heritability of each test and the genetic correlations between them. Results: Girls performed better than boys in flexibility, whereas boys performed better than girls in cardiorespiratory endurance and muscular strength. No sex differences were found in the influence of genetic factors on the physical fitness tests or their mutual correlations. Genetic factors explained 52% (standing long jump) to 79% (sit and reach) of the individual variation in motor performance, whereas individual-specific environmental factors explained the remaining variation. Most of the tests showed modest to moderate genetic correlations. Out of all 105 genetic correlations, 65% ranged from 0.2 to 0.6 indicating that they shared from 4% to 36% of genetic variation. The correlations between individual-specific environmental factors were mostly negligible. Conclusions: Tests measuring the strength of different muscle groups showed only modest correlations, but moderate correlations were found between tests measuring explosive strength, running speed/agility, and cardiorespiratory endurance. Genetic factors explained a major portion of the variation in tests included in the Eurofit and Fitnessgram test batteries and explained the correlations between them. The modest to moderate genetic correlations indicated that there is little redundancy of tests in either Eurofit or Fitnessgram test batteries. [ABSTRACT FROM AUTHOR]

Purpose: The Wheelchair Skills Training Program (WSTP) is underutilized in pediatrics for training manual wheelchair skills because the voluminous manual lacks pediatric specificity and no materials adapted for pediatric manual wheelchair users (PMWUs) are available. A set of resources (storybook, posters, training workbook) based on the WSTP has previously been developed for training basic indoor wheelchair skills with five to 15-year-old PMWUs. Occupational therapists (OTs) and PMWUs expressed a need for additional resources addressing higher-level skills. Two new sets of resources teaching indoor and community wheelchair skills were developed. Objective: Describe OTs' and PMWUs' satisfaction and perceptions regarding usability, relevance and feasibility in pediatrics with the new resources. Methods: A descriptive qualitative study was conducted. A focus group and interviews were respectively conducted with a convenience sample of OTs and a criterion sample of PMWUs to document perceptions regarding satisfaction, usability, relevance and feasibility. A deductive approach to data analyses was used following the Framework Method. Results: Six OTs expressed satisfaction regarding both sets of resources feeling more confident using the WSTP (relevance) and perceiving potential time efficiencies when planning training interventions (feasibility). They provided suggestions to improve the usability of the second set. Six PMWUs participated in the interviews, two of which provided feedback on both sets. They were satisfied with the resources recommending them to novice and temporary PMWUs aged from three to 11 years. Conclusion: Participants' suggested the resources may contribute to reducing the gap between the evidence supporting the WSTP and its utilization in pediatrics. IMPLICATIONS FOR REHABILITATION: Two sets of knowledge transfer resources based on the Wheelchair Skills Training Program (WSTP) are pediatric-friendly materials that could be used in rehabilitation settings to train wheelchair skills among novice and temporary manual wheelchair users. Both sets of knowledge transfer resources may help bridge the gap between the evidence supporting the WSTP and its utilization in pediatrics by responding to clinicians' needs for playful, easy-to-use and condensed materials to use in their interventions. The perspectives of occupational therapists and pediatric manual wheelchair users are important to improve the wheelchair skills training resources so that they align with both knowledge users' needs and preferences.

Children with Cerebral palsy (CP) present movement and posture disorders. The Gross Motor Function Classification System (GMFCS), Manual Ability Classification System (MACS), Communication Function Classification System (CFCS), Eating and Drinking Ability Classification System (EDACS), and Visual Function Classification System (VFCS) enhance the understanding of their performance. We verified inter-rater reliability and associations between the classification levels. Physical therapists classified 100 Brazilian children with CP (3–17 years) according to GMFCS, MACS, CFCS, EDACS, and VFCS. To evaluate inter-rater reliability (Intraclass Correlation Coefficient-ICC) two independent examiners concurrently assessed a subset of 60 participants. According to Spearman's correlation coefficients, there were associations between GMFCS/MACS (r = 0.81), GMFCS/CFCS (r = 0.70), MACS/CFCS (r = 0.73), GMFCS/VFCS (r = 0.61), MACS/VFCS (r = 0.61), CFCS/EDACS (r = 0.58), CFCS/VFCS (r = 0.50), and EDACS/VFCS (r = 0.45) (p <.05). The inter-rater reliability ranged from excellent (ICC = 0.93-0.99) to good (ICC = 0.89), p <.05. The classification systems are reliable, and the levels associated with each other in Brazilian children, especially the GMFCS, MACS, and CFCS. [ABSTRACT FROM AUTHOR]

Background: Developmental Coordination Disorder (DCD) affects school-age children and interferes with the practice of their daily activities. Task-oriented work and motor imagery have shown great efficacy in addressing this problem. Objective: This study presents a protocol that seeks to understand the effectiveness of a combined program of both modalities on the motor competence of children susceptible to the presence of DCD. Desing: Randomised controlled trial. Methods: The participants are children susceptible to the presence of DCD (from 6 to 12 years old) distributed into an intervention group that received a total of 20 protocol sessions and a control group that continued with their usual school routine.

COVID-19 pandemic has disrupted daily routines, causing isolation and quarantine. Technology has emerged as a crucial tool for sustaining essential activities, but children with autism spectrum disorders have faced distinct challenges due to their intricate interaction with it. We employed an online survey to analyse the impact of technology use in online learning, remote assistance and daily life of children with autism along COVID-19, and we have identified benefits and challenges with assistive technology exposed by the pandemic. Findings are divided in (1) seven themes where COVID-19 impacted this population the most and their relationship with technology (remote communication, learning, emotional management, entertainment management, executive functions, activities of daily living, and physical activity and motor skills), and (2) a mapping of technological categories that define the working areas specifically aimed to cover the special needs of children with autism whenever face-to-face interactions are not possible (attention, authoring tools, calculation, e-learning, emotions, entertainment, experience of self, language and communication, memory, planning and time management, social networking, and social skills). These results help provide a more well-rounded knowledge of how to improve technology to make it accessible to autistic children, to handle and avoid services interruption in similar scenarios.

This study aimed to verify the influence of 25 training sessions based on tactical principles and small-sided and conditioned games (SSCG) in developing cognitive and motor decision-making skills of U-12 soccer players. Participants were 25 U-12 elite male soccer players from a Brazilian first division national club. Perceptual-cognitive decision-making skills (quality and response time) were assessed with an objective video-based test (TacticUP®). Perceptual-motor decision-making skills (tactical efficiency) were assessed with the System of Tactical Assessment in Soccer (FUT-SAT). Both instruments were developed based on the same theoretical background (core tactical principles). The 25 training sessions were organised based on tactical principles and SSCG. The sessions were designed considering the individual needs to improve decision-making skills. Results showed improvements (p <.05) in: 1) perceptual-cognitive decision-making skills related to the decision-making time for both offensive and defensive actions and 2) perceptual-motor skills for defensive actions. We also found unexpected results for the quality of decision-making. It decreased for the defensive phase in post-test. We concluded that 25 training sessions based on core tactical principles and SSCG improved perceptual-cognitive related to decision time and perceptual-motor decision-making skills. Improvement of decision-making time apparently is related to improvement in tactical efficiency of U-12 soccer players. [ABSTRACT FROM AUTHOR]

Background: Foot morphology in children is a crucial factor influencing multiple aspects of their physical development. Between the ages of 5 and 10 years, the critical period of child development is when the movement and stability patterns are consolidated that can affect their long-term physical performance and quality of life. The aim of this study is to analyze how the type of foot influences different physical characteristics, laxity, strength, motor tests, and baropodometric variables in children aged 5 to 10 years. Methods: A cross-sectional study involving 196 children was conducted. Different physical characteristics, laxity, strength, motor tests, and baropodometric variables of the sample were analyzed for age and Foot Posture Index (FPI). Results: Differences in all variables were examined by age and FPI. Statistical analysis showed a moderate to high correlation (r > 0.6, p < 0.01) between FPI and the relaxed calcaneal stance position (RCSP) test. Some significant differences were also found in variables related to foot pronation and supination. These results provide valuable information for understanding differences in motor and functional development during childhood and pre-adolescence. Conclusions: The findings highlight the variability in physical and functional development between age and foot type groups, highlighting the importance of considering these differences in the assessment and management of foot-related conditions and biomechanics in childhood. Foot type significantly influences children's growth and development. [ABSTRACT FROM AUTHOR]

Purpose: We provide a case report of "Zoe," a 4-year-old deaf child from a deaf signing family, who presented with a possible case of Childhood Apraxia of Sign (CASign). Method: The description is based on reports from the child's speech-language pathologist, her Individualized Education Program report, and a clinician-created sign imitation task. Results: Zoe's sign articulation errors in American Sign Language differed from those reported for typically developing deaf children and were parallel to the types of errors observed for hearing children with childhood apraxia of speech. Specifically, Zoe produced inconsistent errors across signs, substituted more complex handshapes for simple handshapes, made errors on both unmarked (common) and marked (less common) forms, produced articulatory distortions (rather than substitutions), and exhibited "groping" behaviors (a sequence of attempts to move her hands into the correct position). In addition, Zoe sometimes self-corrected her errors by manipulating her own hands, for example, using her left hand to move the thumb of her right hand into the correct position. Conclusion: Zoe's pattern of sign errors is consistent with an underlying deficit in motor planning and/or programming and may constitute the first reported case of CASign. [ABSTRACT FROM AUTHOR]

Background and Aims: Children with autism spectrum disorder (ASD) present with impairments in social interaction and stereotypic behaviors. About a third may exhibit delays in verbal expression beyond preschool age, potentially categorizing them as nonverbal/minimally verbal (NV/MV), a condition that can persist into adulthood and affect their quality of life. The risk and prognostic factors associated with this reduced verbal outcome remain uncertain. This study aims to identify such factors within children diagnosed with ASD in Cyprus. Methods: In this case-control study, 56 children aged 3–12 years, with an ASD diagnosis, participated. Among them, cases were 22 children classified as ASD-NV/MV, and controls were 34 children classified as verbal (ASD-V), matched by age group and gender. Retrospective information on familial, perinatal, and developmental risk and prognostic factors were collected to calculate the familial risk score (FRS), perinatal risk score (PRS), and developmental risk score (DRS). Early development information was collected for the Early Development Score (EDS) and Early Gesture Score (EGS), to measure the children's skill level as toddlers across milestones. A low EDS and/or low EGS reflected general developmental delays and decreased frequency of early gestures and were considered in the DRS. A parent report questionnaire was utilized to determine the current overall linguistic level and status of participants, distinguishing cases from controls. Results: Age group and gender-matched cases and controls were similar in socioeconomic status and demographic characteristics (p >.05). Among the various familial (e.g., sibling with ASD), perinatal (e.g., prematurity), and developmental (e.g., ASD regression) factors examined individually, as well as collectively as scores in a conditional logistic regression (CLR) model, only a high DRS (p =.03), due to low EDS (p =.04) was significantly associated with linguistic status. When considering all risk scores in a multivariate CLR model, children with a high DRS were more likely to belong to the cases than to the control group (p =.02). In a subsequent model with low EDS and low EGS, only the low EDS was significantly associated with the case group. Results showed that children with ASD and a low EDS, reflecting general delays in early development, were 4.5 times more likely to belong to the cases group than those with a high EDS (p =.02). Conclusions: Early developmental delays in developmental milestones across various domains like gesture, motor, play, linguistic, cognition, and joint attention, in toddlerhood, were associated with later decreased verbal outcomes. Children in the sample with such early delays (low EDS), had a higher likelihood of persistent language delays (ASD-NV/MV) even at late school age. Future studies are needed to duplicate findings and explore possible contributing factors affecting linguistic outcome in ASD through prospective studies exploring within ASD differences. Implications: These findings emphasized the importance of monitoring early development closely for children at risk for ASD, pre-diagnosis, to provide additional early support for those more likely to be ASD-NV/MV. Parents and specialists like pediatricians, educators, speech-language pathologists, among others, can track the EDS score of children at risk for ASD and refer to the appropriate specialists for early stimulation, intervention, and parent consultation promptly.

Background: Caregivers are deeply concerned about children achieving independent walking, and evidence-based rehabilitation support is beneficial. However, current research is confined to a single study on spina bifida aperta, leaving a gap in understanding the timing of independent walking for lumbosacral lipomas. Objectives: This study aimed to examine the factors influencing independent walking in children with lumbosacral lipomas. Design: Retrospective cohort study. Methods: This retrospective cohort study included 124 children who underwent untethering surgery for lumbosacral lipomas. The age (in months) at which the children walked independently was used as the primary endpoint, and potential influencing factors, including the type of spinal lipoma, extent of lipoma removal, magnetic resonance imaging features, congenital anomaly complications, urinary/defecation management requirements, foot/toe symptoms, and orthotic device fabrications were analyzed. Results: Multiple logistic regression analysis showed that the most significant influencing factor for delayed independent walking was the presence of systemic combined anomalies (adjusted odds ratio = 15.5, P <.001), while non-systemic malformations, such as suburethral cleft, had limited effects. A subgroup analysis of 94 patients without systemic combined anomalies showed that the presence of a malformed conus medullaris was significantly associated with delayed independent walking (P =.014). The median age of independent walking in children with Morota's classification type 2 was 14 months, which is 1 month later compared to other types, although this difference was not significant (P =.055). Conclusion: Our findings suggest that complications arising from systemic combined anomalies and the presence of malformed conus medullaris are influencing factors in delays in independent walking in children with untethered lumbosacral lipomas.

Purpose: The aim of this study was to pilot the efficacy of rapid syllable transition (ReST) treatment when provided once per week for a 50-min treatment session for 12 weeks with five children with childhood apraxia of speech. Of central importance was the children's retention and generalization of gains from treatment as indicators of speech motor learning. Method: A multiple-baseline across-participant design was employed to investigate (a) treatment effect on the 20 treated pseudowords, (b) generalization to 40 untreated real words and 10 untreated polysyllabic word sentences, and (c) maintenance of any treatment and generalization goals to up to 4 months posttreatment. To investigate any difference between in-session performance and retention, a comparison was made between data collected during treatment and probe sessions. Results: Treatment data collected during therapy showed all children improving across their 12 treatment sessions. Three of the five children showed a treatment effect on treated pseudowords in the probe sessions, but only one child showed generalization to untreated real words, and no children showed generalization to sentences. Conclusions: ReST treatment delivered at a dose frequency of once per week was efficacious for only one of the five children. In-session treatment data were not a reliable indicator of children's learning. One session per week of ReST therapy is therefore not recommended.

Purpose: The aim of this study was to describe changes in speech intelligibility and interrater and intrarater reliability of naive listeners' ratings of words produced by young children diagnosed with childhood apraxia of speech (CAS) over a period of motor-based intervention (dynamic temporal and tactile cueing [DTTC]). Method: A total of 120 naive listeners (i.e., listeners without experience listening to children with speech and/or language impairments; age range: 18-45 years) orthographically transcribed single-word productions by five children (age range: 2;6-3;11 [years;months]) across three time points over an intervention period (baseline, post-treatment, maintenance). Changes in intelligibility and interrater and intrarater reliability were examined within and across time points. Results: Speech intelligibility significantly increased in children with CAS over the course of treatment, and these gains were also maintained at 6 weeks posttreatment. There was poor-to-fair consistency between listeners (interrater reliability) and excellent consistency within listeners (intrarater reliability) in ratings of speech intelligibility within and across time points. Conclusions: Motor-based intervention increases speech intelligibility following a period of DTTC treatment. Variability among naive listeners of speech intelligibility was also present, with intrarater reliability (within listeners) yielding greater consistency than interrater reliability (between listeners). The implications for including naive listeners as raters of speech intelligibility for research and clinical purposes are discussed. [ABSTRACT FROM AUTHOR]

Purpose: Speech motor skill is refined over the course of practice, which is commonly reflected by increased accuracy and consistency. This research examined the relationship between auditory-perceptual ratings of word accuracy and measures of speech motor timing and variability at pre- and posttreatment in children with childhood apraxia of speech (CAS). Furthermore, the degree to which individual patterns of baseline probe word accuracy, receptive language, and cognition predicted response to treatment was explored. Method: Probe data were collected from seven children with CAS (aged 2;5-5;0 [years;months]) who received 6 weeks of Dynamic Temporal and Tactile Cueing (DTTC) treatment. Using a multidimensional approach to measuring speech performance, auditory-perceptual (whole-word accuracy), acoustic (whole-word duration), and kinematic (jaw movement variability) analyses were conducted on probe words produced pre- and posttreatment. Standardized tests of receptive language and cognition were administered pretreatment. Results: There was a negative relationship between auditory-perceptual measures of word accuracy and movement variability. Higher word accuracy was associated with lower jaw movement variability following intervention. There was a strong relationship between word accuracy and word duration at baseline, which became less robust posttreatment. Furthermore, baseline word accuracy was the only child-specific factor to predict response to DTTC treatment. Conclusions: Following a period of motor-based intervention, children with CAS appeared to refine speech motor control in conjunction with improvements in word accuracy. Those who demonstrated the poorest performance at treatment onset displayed the greatest degree of gains. Taken together, these results reflect a system-wide change following motor-based intervention. [ABSTRACT FROM AUTHOR]

Early childhood educators (ECEs) are ideally positioned to support the development of children's fundamental movement skills (FMS). However, ECEs have little specialised training to support the development of FMS in young children. This study aimed to assess the impact of an e-Learning course on the FMS of preschool-aged children. 145 Preschool-aged children and 42 ECEs from 12 childcare centres participated in the study. ECEs in the experimental group were asked to complete the e-Learning course. A subsample of children (n = 48) was objectively assessed using the Test of Gross Motor Development 3rd Edition (TGMD-3). Additionally, parents of all participating children reported perceptions of their child's FMS to understand if they knew how well their child was progressing. Findings showed a significant increase in TGMD-3 assessed locomotor skills from baseline to follow-up in the intervention group compared to the control group and total FMS but not objective control skills. Parent-reported FMS increased in the intervention group for all locomotor, object control skills, and total FMS. However, the intervention effect for all three measurements was not significant. The results from this study highlight the potential utility of online professional development for ECEs as an approach to improving young children's FMS. [ABSTRACT FROM AUTHOR]

Introduction: The skill domains of fundamental movement skills (FMS), emphasizing gross motor movements, including locomotor skills (LMS) and object control skills (OCS), along with process- and product-oriented measures of FMS, may predict cardiorespiratory fitness (CRF) and muscular fitness (MF) differently. This study investigates the longitudinal relationship from early childhood FMS, focusing on process-oriented LMS and OCS and product-oriented FMS, to CRF and MF in late childhood. Methods: The study involved 441 Finnish children (49.9% female; mean age at baseline, 5.5 yr) over a 6-yr period. FMS was evaluated using the Test of Gross Motor Development, third version, for process-oriented LMS and OCS, and the Körperkoordinationstest Für Kinder (KTK) was used to evaluate the product-oriented FMS. CRF was assessed through the total number of laps completed in the 20-m shuttle run test, whereas MF was measured via repetitions of curl-ups and push-ups. Employing a two-level cross-classified regression analysis and Cholesky decomposition, this study aimed to determine the contributions of product-oriented KTK and process-oriented LMS and OCS. Adjustments for variations in age, measurement intervals, and maturation were achieved through residualization. In addition, gender and body mass index were incorporated as covariates in the analysis. Results: The analysis revealed that process-oriented LMS (CRF: ΔR² = 0.016; MF: ΔR² = 0.014) significantly predicted later health-related fitness, whereas OCS did not. However, KTK exhibited a better ability to predict both CRF (ΔR² = 0.092) and MF (ΔR² = 0.032), overshadowing process-oriented measures. Conclusions: In conclusion, the findings suggest that KTK, which potentially encompasses a broader spectrum of fitness elements along with FMS, more effectively predicts health-related fitness components than process-oriented FMS.

Summary: Background: The prevalence of childhood obesity in the U.S. has increased, likely due to decreased physical activity, increased sedentary behaviour and unhealthy diets. Little is known about the relationships between these factors and weight gain in those under the age of three. Objectives: This study aimed to understand the longitudinal associations of weight gain over 6‐month intervals with child and parent characteristics as children develop from 6 to 36 months. Methods: Mother and infant data were collected at 6‐month intervals from 6 to 36 months. Weight (kg) was the primary outcome variable, and potential explanatory variables included child and parent characteristics, physical activity, motor development, diet and sleep. Structural equation modelling was used to assess associations between explanatory variables and 6‐month weight gain. Results: Weight increased ~1 kg per 6‐month interval (p < 0.001) from 6 to 36 months. Childcare outside of the home at 12 months was associated with 0.272 kg (p = 0.002) greater weight gain at 18 months, while children's physical activity was associated with 0.228 kg (per 2 SD, p = 0.051) less weight gain during the same time period. Mother's TV and screen media use (0.102 kg per hour/day, p = 0.046) and child's intake of high‐energy beverages at 18 months (0.387 kg, p = 0.037) were both associated with greater weight gain at 24 months. Conclusion: Childcare, physical activity, screen media use and high‐energy beverage consumption might affect weight gain at different time points in early childhood. These insights can inform efforts to prevent excessive weight gain and childhood obesity effectively. [ABSTRACT FROM AUTHOR]

Anterior and posterior drooling are prevalent comorbidities in children with neurodevelopmental disabilities. Considering the heterogeneity of the patient population and the multifactorial aetiology of drooling, an interdisciplinary and individualised treatment approach is indispensable. However, no tool for stepwise decision-making in the treatment of paediatric drooling has been developed previously. Within the Radboudumc Amalia Children's Hospital, care for children with anterior and/or posterior drooling secondary to neurodevelopmental disabilities is coordinated by a saliva control team with healthcare professionals from six disciplines. In alignment with international literature, published guidelines, and evidence gained from two decades of experience and research by our team, this paper proposes an algorithm reflecting the assessment and treatment approach applied in our clinic. First, directions are provided to decide on the necessity of saliva control treatment, taking type of drooling, the child's age, and the severity and impact of drooling into account. Second, the algorithm offers guidance on the choice between available treatment options, highlighting the importance of accounting for child characteristics and child and caregiver preferences in clinical (shared) decision-making. Conclusions: With this algorithm, we aim to emphasise the importance of repeated stepwise decision-making in the assessment and treatment of drooling in children during their childhood, encouraging healthcare professionals to apply a holistic approach. What is Known: • Children with anterior or posterior drooling secondary to neurodevelopmental disabilities comprise a heterogeneous group, necessitating an individualised treatment approach. • No stepwise decision-making tool is available for the treatment of paediatric drooling. What is New: • Deciding on the necessity of saliva control treatment should be a conscious process, based on type of drooling, age, and drooling severity and impact. • Type of drooling, age, cognition, oral motor skills, self-awareness, posture, diagnosis, and child/caregiver preferences need to be considered to decide on the optimal treatment.

Assess the potential benefits of using PedBotLab, a clinic based robotic ankle platform with integrated video game software, to improve ankle active and passive range of motion, strength, selective motor control, gait efficiency, and balance. Ten participants with static neurological injuries and independent ambulation participated in a 10-week pilot study (Pro00013680) to assess feasibility and efficacy of PedBotLab as a therapeutic device twice weekly. Isometric ankle strength, passive and active ankle range of motion, plantarflexor spasticity, selective motor control of the lower extremity, balance, and gait speed were measured pre- and post-trial. Statistically significant improvements were seen in flexibility, active range of motion, and strength in multiple planes of ankle motion. Ankle dorsiflexion with knee flexion and knee extension demonstrated statistically significant results in all outcome measures. No significant changes were observed in gait speed outcomes. The use of PedbotLab can lead to improvements in ankle strength, flexibility, and active range of motion for children with static neurological injuries. Future studies aim to evaluate the effect on gait quality and work toward developing a home-based device. [ABSTRACT FROM AUTHOR]

Evaluate changes in two-wheel cycling skills and biking participation goals for children with neurodevelopmental disorders (ND) receiving a home visit and email following iCan Bike camp. Participants: 11 children with ND, 9–16 years, and one of their parents. A cycling skills checklist, two-wheel riding Goal Attainment Scaling (GAS), and biking participation GAS were completed before camp (T1), at support visit after camp (T2), and three months following camp (T3). Parents completed biking practice logs. Participants received a support visit to provide instruction, coaching, and address questions, and an email to check progress. Significant changes were made in two-wheel riding GAS T1 to T2 (p = 0.01), biking participation GAS T2 to T3 (p = 0.02), and cycling skills T1 to T2 (p = 0.01) and T2 to T3 (p = 0.02). Practice frequency was related to cycling skills (0.72, p = 0.01) and biking participation (0.86, p < 0.001); cycling skills were related to biking participation (0.81, p = 0.003). Children improved cycling skills and biking participation following camp, support visit, and email check-in. Children who practiced more had greater cycling skills and biking participation. Encouraging weekly bicycling and providing support may promote cycling skills and participation following camp. [ABSTRACT FROM AUTHOR]

To review the literature on the effects of vestibular training on motor function and balance in children and youth with cerebral palsy. Eight databases (MEDLINE-PubMed, PEDro, Cochrane Library, OTSeeker, Web of Science, Scopus Database, CINAHL and SPORTDiscus.) were searched up to May 15th, 2023. Studies comparing vestibular training with other types of interventions. The DerSimonian and Laird method was employed using random effects models to calculate the pooled estimate of the effect size with confidence intervals of 95%. The risk of bias was assessed with the Cochrane Collaboration's tool and the Grading of Recommendations Assessment, Development and Evaluation approach was used to judge the certainty of the evidence for all outcomes. Eight studies were included comprising 226 participants with cerebral palsy. The meta-analyses demonstrated significant standardized mean differences in favor of vestibular training program compared to other technique(s) for Gross Motor Function Measure (−0.471; 95% confidence intervals: −0.919 to −0.023) and balance (−0.546; 95% confidence intervals: −0.916 to −0.176). Vestibular training has potential benefits in the short-term as a therapeutic approach for improving gross motor function and the balance in children and youth with cerebral palsy, but further research is needed.

To synthesize evidence about physical fitness levels in children with developmental coordination disorder (DCD) compared with typically developing (TD) children. We searched four databases (PubMed, Scopus, Web of Science, and PsycINFO) for cross-sectional, case-control, and cohort studies comparing physical fitness between children with and without DCD. We assessed the methodological quality of the studies with the Newcastle-Ottawa Scale (NOS). We calculated Cohen's d effect sizes to provide clinical evidence of group differences in aerobic capacity, anaerobic capacity, muscle strength, body composition and flexibility. We included 32 studies for qualitative synthesis after applying eligibility criteria. All selected studies ranged from moderate to high research quality. Effect sizes in favor of typically developing children over children with DCD were large for aerobic capacity (d = 1.15), anaerobic capacity (d = 0.90), and muscle strength (d = 0.79), and small for body composition (d = 0.43) and flexibility (d = 0.21) outcomes. Children with DCD presented significantly lower physical fitness than their typically developing peers, particularly in aerobic and anaerobic capacity and in muscle strength. [ABSTRACT FROM AUTHOR]

Recent research has reported effects of socioeconomic status on neurobehavioral development as early as infancy, including positive associations between income and brain structure, functional connectivity, and behavior later in childhood (Ramphal, Whalen, et al., 2020; Triplett et al., 2022). This study extends this literature by investigating the relation of maternal prenatal social disadvantage (PSD) to neonatal amygdala and hippocampus functional connectivity and whether socioeconomic-related alterations in functional connectivity subsequently predict behavior at age 12 months in a large, socioeconomically diverse sample (N = 261 mother–infant dyads). PSD was assessed across gestation; neonatal magnetic resonance imaging was completed within the first weeks of life; and infant internalizing and externalizing symptoms were evaluated using the Infant–Toddler Social and Emotional Assessment at age 12 months. The results showed that PSD was significantly related to neonatal right amygdala and left hippocampus functional connectivity with prefrontal and motor-related regions. Social disadvantage-related right amygdala and left hippocampus functional connectivity with these regions was subsequently related to infant externalizing and internalizing symptoms at age 12 months. Building off an emerging literature exploring prenatal impacts on neonatal functional connectivity, this study further emphasizes the important role of the maternal environment during gestation on infant brain function and its relationship with externalizing and internalizing behavior in the first years of life. The results suggest that the prenatal socioeconomic environment may be a promising target for interventions aimed at improving infant neurobehavioral outcomes. Public Significance Statement: This study suggests that mothers' prenatal social disadvantage (PSD) impacts the brain function of their infants in the weeks shortly after birth. Additionally, the study reports a link between infant brain function shortly after birth and infant behavior 1 year later. The study results suggest that mother's PSD may be a promising target for interventions that improve infant health. [ABSTRACT FROM AUTHOR]

Purpose: Explore occupational therapists' (OTs) and speech language pathologists' (SLPs) process of selecting and applying motor learning strategies (MLS) in their interventions for children with acquired brain injury (ABI), and identify similarities and differences between OTs and SLPs in MLS selection and application. Methods: This qualitative descriptive study involved individual semi-structured interviews with OTs and SLPs from the ABI program at Holland Bloorview Kids Rehabilitation Hospital (Toronto, Canada). Interviews were analyzed using thematic analysis. A modified constant comparison method permitted comparison within and between professions. Results: Four OTs and three SLPs were interviewed. Four themes were developed: aligning MLS application with the child's cognitive ability, using MLS to promote success within a single session, adjusting MLS across treatment sessions, and promoting generalization and transfer of motor skills beyond the therapy session. MLS application was predominately based on child-specific factors with task-specific considerations. OTs and SLPs used similar clinical reasoning processes for selecting and applying MLS. Conclusions: This study provides a greater understanding of OTs' and SLPs' clinical reasoning process when applying MLS in pediatric ABI interventions. The similarities in MLS selection and application between disciplines suggest that an interprofessional approach to MLS is suitable for pediatric ABI rehabilitation. IMPLICATIONS FOR REHABILITATION: Pediatric occupational therapists and speech language pathologists use a similar process for selecting and applying motor learning strategies (MLS) in their interventions Clinicians continually reflect upon and adapt their use of MLS based on each child's performance, progress, and goals Adopting an interprofessional approach to MLS selection and application, including the use of a common MLS language, has the potential to optimize motor outcomes in pediatric acquired brain injury rehabilitation [ABSTRACT FROM AUTHOR]

Aim: Studies have demonstrated that family centeredness, or family involvement in decision-making and care provision, is crucial for achieving the best results in pediatric rehabilitation and is also directly associated to parental/caregiver satisfaction with rehabilitation services. This study aimed to explore the potential determinants of parents'/caregivers' satisfaction with rehabilitation services based on the various elements of family centeredness. Material and Method: Authors included the parents/caregivers of 120 children with physical disabilities aged 5-18 years (mean 10.14 years, SD 4.17). The Measure Process of Care-20 (MPOC-20) was used to assess parents'/caregivers' perceptions of the family centeredness in provision of rehabilitation services and therefore parental/caregiver satisfaction with rehabilitation service delivery to children. Results: Service-related and child-related factors accounted for 78% and 67% of the variances in the parents'/caregivers' satisfaction with being provided opportunities for them to make decisions about rehabilitation services (MPOC-20-Enabling and Partnership subscale), respectively. Parental/caregiver satisfaction with service delivery in the context of sharing information about child's progress was correlated with service-related, child-related, and parent/caregiver-related factors (adjusted R2=0.75, 0.71, and 0.68, respectively). Satisfaction with service delivery regarding coordinated and comprehensive care was significantly influenced by the service provider and the parent/caregiver-related variables (R2=0.63 and R2=0.59, respectively). Finally, in the event of satisfaction with services in terms of respectful and supportive care, each factor accounted for a small and approximately equal amount of variance in the mean score of relevant MPOC-20 subdomain (range of adjusted R2=0.10-0.18). Conclusion: Factors or determinants identified in the current study as having the potential to increase parents'/caregivers' satisfaction with rehabilitation services should be considered when providing rehabilitation services.

Importance: Understanding the significance of motor skills in promoting physical fitness (PF) can offer valuable insights for devising comprehensive intervention and clinical rehabilitation programs for children with global developmental delay (GDD). However, it remains unclear whether fundamental motor skills (FMS) can improve the PF of children with GDD. Objective: To investigate the correlation between FMS and PF in children with GDD. Methods: A total of 180 children with GDD and 180 typically developing (TD) children aged 3–5 years were selected. All participants completed the Gesell Developmental Schedule, FMS, and PF tests at Beijing Children's Hospital between September 2022 and August 2023. Partial correlation and regression analyses were performed to examine the relationship between FMS and PF. Results: Children with GDD had significantly lower FMS and PF scores compared to TD children (P < 0.05). No significant differences were found between males and females with GDD in FMS and PF score (P > 0.05). A more severe developmental delay was associated with lower FMS and PF scores. The correlation coefficients between individual FMS items and individual PF items, as well as the total PF score, ranged from 0.20 to 0.56. Regression analysis indicated that manual dexterity (β = 0.241, P = 0.029) and body balance (β = 0.399, P = 0.001) significantly predicted the total PF score. Interpretation: In children with GDD, both FMS and PF are underdeveloped. Focusing on motor skills development is vital for promoting their PF. [ABSTRACT FROM AUTHOR]

Background: The development of motor competence (MC) during childhood is crucial for future physical activity and health outcomes, and it is affected by both biological and psychosocial factors. Most MC research has focused on children's age, with fewer studies examining separate associations between MC and biological maturation. Methods: This cross-sectional study used network analysis to assess the nonlinear associations between biological maturation (the child's percentage of predicted mature stature to indicate somatic maturation), chronological age, sex, BMI, and MC (Test of Gross Motor Development, third edition) in 218 children (100 boys, 118 girls) aged 7–9 years. Results: Biological maturation was not significantly associated with MC in boys and weakly associated with MC in girls for the dribble, under-hand throw, and gallop. Age was positively associated with MC in girls and boys. Centrality measures indicated that the gallop and slide in girls and the dribble, catch, and run in boys were the most important network variables. Positive associations were observed between maturation and BMI for girls (r = 0.579) and, to a lesser degree, for boys (r = 0.267). Conclusions: The findings suggest that age, rather than biological maturation, is positively associated with MC in 7- to 9-year-olds. Centrality measures showed that some skills may influence other skills. [ABSTRACT FROM AUTHOR]

Background/Objectives: During the COVID-19 pandemic, children in Japan were restricted from sports and outdoor activities. Regular physical activity is essential for healthy growth and development in children, with recommendations advocating for activities such as strength training. However, the long-term effects of the restrictions have not been fully investigated. This study aimed to evaluate the effectiveness of an "exercise class", specifically a dance program, designed to improve motor function in elementary school children affected by the coronavirus disease 2019 (COVID-19) pandemic, which may have compromised their motor function. Methods: The dance program was developed by a sports science teacher, a professional dancer, and a physical therapist, and it was evaluated in a community-based participatory study. Trained dance instructors conducted one-hour dance sessions in a medical center, held once a week for two months from June to August 2023. A physical therapist and dance instructors led the elementary school children. Outcome measures included grip strength, lower extremity muscle strength, back muscle strength, dynamic balance function during movement, physical activity time, and body fat percentages. Descriptive statistics were used for analysis. Results: Twenty-four children aged 6–9 years participated in the exercise class over a two-month period. Improvement was observed in grip strength, lower extremity muscle strength, and dynamic balance function during movement. However, physical activity time, body fat percentages, and back muscle strength did not change. Conclusions: The results indicated a significant improvement in motor skills. Dance is an inexpensive program that elementary school children can enjoy while improving their motor skills. [ABSTRACT FROM AUTHOR]

(1) Background: Pulmonary hypertension (PH) increases pulmonary vascular resistance and right ventricular (RV) afterload. Assessment of RV systolic function in PH using RV fractional area change (RV FAC) as a marker directly correlates with mortality and the need for extracorporeal membrane oxygenation (ECMO). However, few studies have assessed neurodevelopmental outcomes. We hypothesize that cardiac RV systolic dysfunction with lower RV FAC is associated with worse neurodevelopmental impairment (NI). (2) Methods: Retrospective study of 42 subjects with PH to evaluate neurodevelopmental outcomes in the first two years of life based on (i) subjective assessment of RV systolic function and (ii) RV FAC, a specific echocardiographic marker for RV function. (3) Results: Subjects from the initial study cohort (n = 135) with PH who had long-term follow-up were divided into RV dysfunction (study, n = 20) and non-RV dysfunction (control, n = 22) groups. RV FAC in the study vs. control group (0.18 vs. 0.25) was lower (p = 0.00017). There was no statistically significant difference in NI either with RV dysfunction or lower RV FAC. Although not significant, RV dysfunction was associated with longer mean duration of mechanical ventilation, time on ECMO, and length of stay. In the initial cohort (135), mortality was 16.3% and the percentage of NI was 62%. (4) Conclusions: Neonatal pulmonary hypertension is associated with a high degree of neurodevelopment impairment. Early RV systolic dysfunction, as identified by RV FAC, was not an optimal predictive biomarker for infants with PH and neurodevelopmental impairment. [ABSTRACT FROM AUTHOR]

Background: The gross motor function measurement is considered as the gold standard for the motor assessment of children with cerebral palsy. The aim was to carry out the cross-cultural adaptation and investigate psychometric properties. Methods: A total of 150 children with cerebral palsy aged 2–16 (mean 8.82 ± 3.78 years; 54.7% male) included. The Gross Motor Function Measurement was adapted into Turkish. Two physiotherapies independently administered the gross motor function measurement. Internal consistency and intra/inter-rater reliability were assessed using Cronbach's alpha, intraclass-correlation-coefficient. Standard-error-of-measurement, minimal-detectible-change calculated. The Bland–Altman method was applied to estimate the measurement bias in reliability analysis. Construct validity assessed with Spearman's correlation coefficient between the gross motor function measurement and the gross motor function classification system, pediatric-evaluation-of-disability-inventory—mobility; confirmatory-factor-analysis was carried. Results: Internal-consistency (α: 0.997–1.00); reliability indices were excellent for total scale (intraclass-correlation-coefficient for intra-rater reliability 0.994–0.999, inter-rater reliability 0.997–0.999) and for each sub-dimension and total score. Standard-error-of-measurement was ranging 1.044–1.677, minimal-detectible-change was 2.435–5.520. Construct validity was supported by strong to excellent negative significant correlations (p < 0.05).

Background: Childhood obesity is a significant public health crisis that is exposing children to associated morbidities and premature mortality. However, parents can positively influence physical activity trajectories and improve health outcomes by nurturing fundamental movement skills (FMS) in children. This is the first study to explore the determinants of family FMS practice via a systematic synthesis of qualitative evidence. Methods: Keyword searches were completed in SPORTDiscus, PubMed, Scopus, Web of Science, and Embase. Studies that offered perspectives relating to influences on the FMS of 2–6-year-old children in the family context via qualitative approaches, including visual methodologies that provided an important voice to children, were included. A thematic analysis was used to establish key themes. Results: The emergent themes included parent knowledge and beliefs, self-efficacy of parents to teach, and the home environment. Parents often undervalued FMS and lacked the self-efficacy to teach due to poor understanding, conflicting priorities, and multifaceted societal influences. Children preferred autonomous play and socialisation but were negatively influenced by technology and restrictive household rules. Conclusions: Greater knowledge exchange between stakeholders is necessary to empower parents and enhance FMS application at home. More community initiatives could facilitate greater access to outdoor spaces, facilities, and equipment, which may improve family engagement with FMS. [ABSTRACT FROM AUTHOR]

Objective: Children face the risk of dehydration in varying amounts during the day due to reasons such as physical activity, sweating, eating salty foods and drinking carbonated beverages. It is assumed that dehydration can lead to impaired motor skills and cognitive performance since it affects brain function. However, inconsistencies in study results, test times and problems caused by heat stress make new research mandatory. In our research, we examined the effects of exercise-induced mild dehydration on motor skills and cognitive performance in active/sedentary boys who do/do not do regular physical activities in their daily lives. Methods: The study included 112 boys who do regular physical activity (n:57; 12.40 ± 0.49age) and sedentary (n:55; 12.49 ± 0.50age). The children were given a 12-h hydration program. Mild dehydration was created by giving exercises after hydration measurements. In case of hydration and mild dehydration, Bruininks-Oseretsky Motor Proficiency and d2 attention test were applied to the children. For comparison, Repeated Measures ANOVA and Bonferroni post-hoc test was performed at the second level. Results: According to the hydration and mild dehydration comparison results, there was no difference in total score of Fine Motor Skill Sensitivity, Fine Motor Skill Integration, Hand Dexterity and Bidirectional Coordination, Balance, Running Speed and Agility, Hand-Arm Coordination, Strength, and BOT-2 in children. There was a decrease in both groups in terms of Focused Attention, Processing Speed, Accuracy, Concentration Performance and Attention Span. Conclusion: As a result, mild dehydration is associated with daily physical activity in children (physical education classes, etc.) or it can easily occur due to food/beverage preferences. It may affect children's performance of school curriculum and extracurricular activities. It shows that maintaining optimal hydration is important. [ABSTRACT FROM AUTHOR]

Summary Effects of sleep on procedural (implicit) memory consolidation in children remain controversial. The aim of this systematic review was to synthesise the evidence on the influence of sleep on motor skills acquisition in children. Four electronic databases were searched: PubMed, Cochrane Central Register of Controlled Trials (CENTRAL), Excerpta Medica Database (Embase), and Biblioteca Virtual em Saúde (BVS). Original studies, published until October 17, 2023, on motor skill acquisition in children aged ≤12 years, in which the intervention group slept after motor skill training, while the control group remained awake, were considered for inclusion. Risk of bias was evaluated using the Cochrane's Risk of Bias 2 tool. The review protocol was pre‐registered at the International Prospective Register of Systematic Reviews (PROSPERO protocol number: CRD42022363868) and all reported items followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guidelines. Of the 7241 articles initially retrieved, nine met the primary criteria and were included in this review. Of these, six studies reported that daytime or night‐time sleep intervention improved motor skill acquisition, as compared to wakefulness. All studies presented a high risk of bias. In conclusion, the evidence summarised suggests that sleep may enhance motor skills acquisition and could be important for motor development in childhood. However, due to the high risk of bias in the included studies, future randomised controlled trials with high methodological quality are necessary to better clarify this topic. [ABSTRACT FROM AUTHOR]

Background: Given the significance of motor competence (MC) for healthy development and as a cornerstone for lifelong physical activity (PA), it is crucial to understand the manifold factors that are associated with MC. Thus, the aim of the present study was to investigate correlates of children's MC and their fundamental movement skills (FMS) within their daily life from a comprehensive biopsychosocial-ecological perspective. Methods: This is a cross-sectional sub-study of the 'Physical Literacy for Communities (PL4C)' WAVES cohort study conducted in the West Vancouver School District, Canada. Motor competence was assessed using the PLAYfun tool including overall MC score and five FMS category scores, namely, running, locomotor skills, upper and lower body control and balance skills. By means of structural equation modeling (SEM), direct associationswith MC and with the specific FMS categories addressing physical activity behavior, self-perceived physical literacy, parenting, and school ground design were investigated. Results: A total of 355 children with a mean age of 7.5 years and 111.1 min of MVPA per day participated. The group comprised 51% boys and 47% girls from 14 elementary schools. Most children were at an emerging MC-level (71%), while those at a competent MC-level exhibited significantly more daily minutes of MVPA (123 versus 109, p = 0.001). Additionally, they played outdoors more frequently and engaged in more instructor-led PA. The results revealed that logistical support from parents had not only a direct positive association with overall MC, both for girls and boys, but also with most of the FMS categories. However, the correlates of MC varied between genders and showed different patterns across the five FMS categories. While time spent in sports or coach-/instructor-led physical activities had a significant SEM generated direct effect only for boys' MC and for locomotor, upper body object control and balance, the aesthetic design of the school grounds was only associated with girls' MC and those same three FMS categories. Multivariate SEM could explain 26% of variance for girls' MC and 30% for boys'. Conclusions: This exploratory baseline assessment revealed parental logistical support as an important correlate of MC, irrespective of gender. There were distinct gender patterns across biopsychosocial-ecological correlates influencing MC and FMS. Despite the heterogeneity of the results, our findings indicate a potential role of school ground design in supporting the development of children's MC, especially for girls. Key Points: • The influence of biopsychosocial-ecological correlates on motor competence (MC) varied based on gender and the specific fundamental movement skill (FMS) categories. • While parental logistical support demonstrated a positive direct association with both genders' MC and most of the FMS categories, coach-led physical activities appeared to enhance only boys'. • The positive direct association of outdoor play on boys' MC and of school ground aesthetics on girls' MC might suggest the role of the physical environment in MC development.
