Short- and Long-Term Changes in Balance After Active Video Game Training in Children With and Without Developmental Coordination Disorder: A Randomized Controlled Trial.

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.

Association between Contextual Factors and Affordances in the Home Environment of Infants Exposed to Poverty.

Home environments of infants exposed to poverty exhibit fewer affordances for child development. This study aimed to investigate the association between contextual factors and affordances in the home environments of infants facing poverty. Term infants (n = 128) were divided into two groups: (1) exposed group (EG), comprising term infants exposed to poverty, and (2) comparison group (CG), consisting of term infants classified with medium and high socio-economic status. The main dependent variables were physical space, variety of stimulation, gross and fine motor toys, and the total score; measured using the Brazilian version of the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) questionnaire, named Affordances no Ambiente Domiciliar para o Desenvolvimento Motor-Escala Bebê. Statistical analysis employed independent sample t-tests or Mann-Whitney tests, chi-square tests, and stepwise multiple linear regression models to evaluate predictors of less adequate home environments. The EG presented significantly fewer affordances in gross motor toys (Cohen's r = 0.353; p < 0.01); fine motor toys (Cohen's r = 0.327; p < 0.01); and total score (Cohen's r = 0.377; p < 0.01). Binary logistic regression analysis showed a significant association (r2 = 0.828, p < 0.01) between the less than adequate home environment category and maternal age (p = 0.043, OR: 0.829 (0.692-0.994)), revealing that maternal age was associated with better quantity and quality of affordances for child development.

Late preterm and very preterm infants differ in the acquisition time and quantity of reaches with grasping at reaching onset: an exploratory study.

Introduction: The onset of manual reaching allows the expansion of the infant's interaction with the environment. When born preterm, infants become vulnerable to problems in the development of reaching. However, it is still unknown whether there are differences in reaching according to the degree of prematurity. Objective: This study aimed to explore the differences in reaching acquisition and behavior between late preterm and very preterm infants, as well as whether age and clinical variables influence the results. Method: This is an exploratory, comparative, observational study. In total, 24 infants were included soon after reaching onset; 12 infants were born late preterm (35.55 ± 0.67 gestational weeks) and 12 very preterm (30.60 ± 0.05 gestational weeks). Infants were placed in a baby seat, and a toy was placed at a reachable distance for 2 min. Reaching behavior was the primary variable; birth weight and length of hospital stay were secondary variables. Results: The age of reaching onset was higher in the very preterm group. The proportion of reaches with grasping was higher in the late preterm group. These differences were affected by the lower birth weight and longer length of hospital stay in the very preterm group. The proportions of proximal and distal adjustments did not differ between groups. Conclusion: Very preterm infants presented disadvantages in the acquisition time and the number of reaches with grasping, but not in the proportions of proximal and distal adjustments of reaching, relative to late preterm infants. Group differences were influenced by clinical variables.

Task-Related Differences in End-Point Kinematics in School-Age Children with Typical Development.

Understanding whether and how children with typical development adapt their reaches for different functional tasks could inform a more targeted design of rehabilitation interventions to improve upper extremity function in children with motor disabilities. This prospective study compares timing and coordination of a reach-to-drink, reach-to-eat, and a bilateral reaching task in typically developing school-aged children. Average speed, straightness, and smoothness of hand movements were measured in a convenience sample of 71 children, mean age 8.77 ± 0.48 years. Linear mixed models for repeated measures compared the variables by task, phases of the reach, task x phase interactions, and dominant versus non-dominant hands. There were significant main effects for task and phase, significant task x phase interactions (p < 0.05), and a significant difference between the dominant and non-dominant hand for straightness. Hand movements were fastest and smoothest for the reach-to-eat task, and least straight for the bilateral reaching task. Hand movements were also straighter in the object transport phases than the prehension and withdrawal phases. These results indicate that children with typical development change their timing and coordination of reach based on the task they are performing. These results can inform the design of rehabilitation interventions targeting arm and hand function.

Health-related quality of life in children with developmental coordination disorder: a systematic review.

The aims of this study were (1) to synthesize evidence of the general health-related quality of life in children with DCD compared to their typically developing peers, and (2) to verify which domains of HRQOL are more compromised in children with DCD. A systematic search was carried out to identify cross-sectional studies that evaluated self-perception and/or the parent's perception of the HRQOL in children with and without DCD as an outcome. The methodological quality of the studies was assessed, and the effect size calculated. Initial searches in the databases identified 1092 articles. Of these, six were included. Most of the articles (5/6) included noted that children with DCD show a significantly lower HRQOL than their typically developing peers. Regarding the most compromised HRQOL domains, the results are heterogeneous. Most studies (3/6) had moderate methodological quality, and two studies were classified as high methodological quality. Effect sizes ranged from low to high.

Type of active video-games training does not impact the effect on balance and agility in children with and without developmental coordination disorder: A randomized comparator-controlled trial.

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.

Sticky Mittens Training to Improve Reaching Skills and Manual Exploration of Full-Term and At-Risk Infants: A Systematic Review.

AIM: To systematically review evidence of the effectiveness of sticky mittens training to improve reaching skills and manual exploration of full-term and at-risk infants and optimal training dosage. METHODS: The Cochrane Collaboration and Preferred Reporting Items for Systematic Reviews and Meta-Analyses guided this systematic review. The electronic search was performed from September 2017 to August 2021 on PubMed, Scopus, Science Direct, and Cochrane databases. Eligibility criteria followed PICO terms: clinical trials investigating the effects of sticky mittens training on reaching skills and manual exploration of full-term and at-risk infants. PEDro scale and GRADE assessed methodological quality and quality of evidence, respectively. RESULTS: Eight studies (313 children) were included. Five studies found statistically significant differences between experimental and control groups (62.6%). One study presented high methodological quality. Evidence synthesis showed very low and low evidence of the beneficial effects of sticky mittens training in full-term and at-risk infants, respectively. CONCLUSIONS: Findings suggest that sticky mittens training facilitates reaching skills and manual exploration. However, results should interpretation with caution because studies targeted full-term infants. Future research should focus on infants at risk or with motor impairments since sticky mittens training seems to show positive effects and is easy to apply.

Active Video Games Performance and Heart Rate on the Wii or Kinect in Children with and without Developmental Coordination Disorder.

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.

Psychometric properties of the Infant Motor Profile (IMP): A scoping review protocol.

INTRODUCTION: The IMP is a novel video-based instrument to assess motor behavior of infants. It evaluates gross and fine motor behavior in five domains: variation, adaptability, symmetry, fluency, and performance. The latter assesses motor milestones, the other four domains assess qualitative aspects of movements. Literature suggests that it is a promising tool for pediatric health care, as its assists early detection of neurodevelopmental disorders and facilitates the design and monitoring of early intervention. This, this scoping review (ScR) aims to evaluate the psychometric properties of the Infant Motor Profile (IMP). MATERIAL AND METHODS: A systematic search will be conducted to identify relevant studies up to October 15, 2022. All papers published in English that evaluated or used the IMP in children under two years of age will be included. The search will be performed in Pubmed, Lilacs, PEDro, Scielo, CINAHL, Embase, Web of Science, Ovid PsycINFO, Cochrane Database of Systematic Reviews, as well as in gray literature sources following the University of Toronto library guidelines. Standardized data extraction forms (Excel Tables) will be used to collect information. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for the Scoping Reviews (PRISMA-ScR) Checklist and JBI guidelines will be taken into consideration for results analysis and reporting. DISCUSSION: This Scoping Review will summarize available knowledge on the psychometric properties of the IMP. By proving that IMP is a reliable tool, a valid predictor of neurodevelopmental outcomes and a responsive instrument to measure change induced by early intervention, this will facilitate the implementation of the IMP in pediatric health care. It will assist the detection of infants at high risk of neurodevelopmental disorders, and it will facilitate the design of the tailor-made early intervention. SCOPING REVIEW PROTOCOL REGISTRATION: This scoping review protocol has been registered at Open Science Framework (OSF) (https://doi.org/10.17605/OSF.IO/4HYKZ).

Parental Practices and Environmental Differences among Infants Living in Upper-Middle and High-Income Countries: A Cross-Sectional Study.

Parental practices and environmental factors can impact a child's development and, consequently, functionality. The objective is to assess the parental practices and environmental differences in healthy and at-risk infants at 3-6 months of age living in upper-middle (Brazil) and high-income (Italy) countries. A total group of 115 infants was identified and classified into four groups: healthy Italian infants (H_IT); Italian infants exposed to biological risk factors (R_IT); healthy Brazilian infants (H_BR); and Brazilian infants exposed to environmental risk factors (L_BR). The dependent variables were parental practices and environmental factors, which were assessed through a semi-structured interview and the "variety of stimulation dimension" from the Affordances in the Home Environment for Motor Development-Infant Scale (AHEMD-IS) questionnaire. Descriptive analyses, a multivariate analysis of variance (MANOVA), and correlation tests were applied. Regarding the environment and parental practices, the mother's age, maternal and paternal education, civil status, and variety of stimulation showed significant differences among the infants living in Brazil or in Italy. There were strong dissimilarities in parental practices and environmental factors among infants living in low/upper-middle and high-income countries. Since the home environment is the main stimulus for infant growth and development, our results are meaningful for providing knowledge about these two different cultures.

Manual exploratory behaviors in six-month-old infants at environmental and biological risk.

BACKGROUND: Exploratory behaviors are essential and may improve different skill development. Different risk factors may negatively impact neuromotor development, such as biological risk and environmental risk. OBJECTIVE: Assess and discriminate exploratory behaviors of infants at environmental or biological risk and infants at non-risk. METHODS: Sixty-four six-month-old infants were divided into three independent groups: Group 1 (G1), 28 healthy full-term infants; Group 2 (G2), 21 full-term infants of low socioeconomic status (SES); Group 3 (G3), 15 very preterm infants. Nine exploratory behaviors were assessed: fingering, mouthing, waving, tapping, banging, transferring, rotating, alternating, and squeezing. RESULTS: For the malleable object, fingering (p = 0.005) and transferring (p = 0.046) behaviors were different between G2 and G3 whereas waving behavior (p = 0.041) differed between G1 and G3 and transferring (p = 0.003) between G1 and G2. For the rigid object, waving was different between G1 and G3 (p = 0.018) whereas transferring behavior differed between G2 and G3 (p = 0.019). Total number of behaviors was significantly different between G1 and G2 for malleable (p = 0.019) and rigid objects (p = 0.009). Intragroup analysis revealed differences between malleable and rigid objects for transferring (p = 0.013), squeezing (p < 0.0001), fingering (p < 0.0001), and banging (p = 0.013) behaviors in infants from G1. Fingering and squeezing (p < 0.0001) were different between malleable and rigid objects in G2 (p = 0.009 and p < 0.0001) and G3 (p = 0.004 and p < 0.0001). CONCLUSION: Risk factors and object properties influence exploratory behaviors, mainly in low SES infants. Fingering and banging behaviors are favored by rigid objects, while squeezing is favored by malleable objects.

Reaching skills in six-month-old infants at environmental and biological risk.

OBJECTIVES: To assess kinematic parameters and proximal and distal reaching adjustments of infants at biological or environmental risk and compare with reaching performance of six-month-old full-term infants without known risk factors. METHODS: This blinded cross-sectional study included 62 infants at six months of age divided into three independent groups: Group with no known risk factor (NRF), 28 full-terms with no risk factors; Low SES group (LSES):19 full-terms classified as low socioeconomic status and no biological risk; Very preterm group (VPT), 15 very preterm infants at six months corrected age and no environmental risk. Infants were placed in a reclined baby chair at 45°, and a malleable and unfamiliar object was presented to the infant at 5-second intervals to elicit reaching movements. RESULTS: Infants from LSES presented reaching duration (p = 0.032, Cohen's f = 0.349) and movement unit (p = 0.033, Cohen's f = 0.351) significantly higher than VPT group. Horizontal hand orientation was moderately associated with infants at environmental risk (p = 0.031; Cramer's V = 0.30). CONCLUSION: Infants of low socioeconomic status perform less functional reaching movements than very preterm infants at six months corrected age. Socioeconomic status may impact more on reaching skills than biological risk. Given the importance of reaching for infant development, low-cost public health strategies are needed to identify possible delays.

Does late preterm birth impact trunk control and early reaching behavior?

The aims of the study were to 1) verify the level of trunk control longitudinally and reaching behavior while sitting in two positions in late preterm (LPT) and full-term (FT) infants, 2) determine whether the level of trunk control relates to reaching outcomes. Twenty LPT infants and 36 infants born FT were assessed via three in-lab visits: at 6, 7, and 8 months. At each visit, the Segmental Assessment of Trunk Control (SATCo) and reaching assessment were performed, where the infants were positioned sitting in the ring and at 90° of flexion of hips, knees, and ankles. Accurate manual support to the trunk was provided in each visit. LPT infants presented a lower level of trunk control over time. LPT infants presented a higher percentage of unimanual reaches and successful grasping at 7 months' visit, and a higher number of reaches at 8 months' visit compared to FT infants. The sitting positions did not influence reaching performance. The level of trunk control relates to functional reaching strategies only in FT infants. This study might provide insights for clinicians for understanding the level of trunk control, the importance of reaching behaviors for exploration, and considering these behaviors as strategies for intervention.

Lower Limb Sensorimotor Training (LoSenseT) for Children and Adolescents with Cerebral Palsy: A Brief Report of a Feasibility Randomized Protocol.

Motor disorders in cerebral palsy (CP) are often accompanied by disturbances of sensation and impaired somatosensory functions have been reported in individuals with CP. To test the feasibility of a sensorimotor training protocol for lower limbs in children and adolescents with unilateral and bilateral CP, and to analyze the preliminary effects of this training on sensory and motor variables. This is a single-blind, prospective phase I feasibility randomized protocol. A total of twenty participants with uni or bilateral cerebral palsy, GMFCS level I-III, ages 5 to 20 years will be recruited. The LoSenseT protocol is composed of tactile and proprioceptive activities in a child-friendly format. An original qualitative feedback questionnaire was developed to assess the protocol feasibility. Additionally, proprioception, tactile discrimination, postural stability, and gait parameters will be assessed. The LoSenseT protocol can support the implementation of interventions targeting lower limbs somatosensory impairments in individuals with CP.

Wii training versus non-Wii task-specific training on motor learning in children with developmental coordination disorder: A randomized controlled trial.

BACKGROUND: Wii-based interventions have shown significant benefits in motor learning for children with developmental coordination disorder (DCD); however, studies comparing the effects of Wii interventions versus matched non-Wii interventions, such as task-specific training (TST), are scarce. OBJECTIVE: We compared motor learning in children with DCD who participated in 12 sessions of Wii-based training and those participating in 12 closely matched non-Wii TST sessions as well as when the highest improvements in performance occurred. METHODS: In total, 32 children with DCD (16 per group) were randomly allocated to receive the Wii intervention or TST during 12 sessions. Motor learning was assessed in 3 consecutive phases during the intervention and was determined by the mean of the games scores obtained in the: (1) first 4 sessions, (2) intermediate 4 sessions, and (3) last 4 sessions. Six different tasks (table tennis, frisbee, archery, bowling, tightrope walking/balance beam, and marble balance/balance disc) were performed in every session. Each session lasted 42min (time on task). RESULTS: Wii training and TST elicited improvements in motor learning, as assessed by increased scores with the frisbee and marble balance/balance disc tasks. However, Wii training elicited better performance in the archery and bowling tasks, whereas only TST elicited improvements in the balance beam and table tennis tasks. CONCLUSION: Wii training is not always superior to non-Wii training, and improvements are based on the type of task trained. Thus, each type of intervention benefits a certain skill.

Symptoms of anxiety and depression in schoolchildren with and without developmental coordination disorder.

We examined whether reported higher frequencies of anxiety and depression symptoms are related to the presence of developmental coordination disorder in school-age Brazilian children. A total of 272 children were assigned to six groups according to age and motor performance. The Movement Assessment Battery for Children-Second Edition evaluated the motor performance. The Spence Children's Anxiety Scale and the Child Depression Inventory assessed anxiety and depression symptoms, respectively. Brazilian children are at high risk for anxiety, regardless of motor performance and age. However, children with developmental coordination disorder report significantly more depressive symptomatology in 10-12 years compared to typically developing children.

Symptoms of anxiety and depression in children with developmental coordination disorder: a systematic review / Sintomas de ansiedade e depressão em crianças com transtorno do desenvolvimentoda coordenação: uma revisão sistemática

Abstract Objective To find evidence of the symptoms of anxiety/depression in children with developmental coordination disorder as compared to their typically developing peers at both the group and individual level, and to identify how many different tools are used to measure anxiety and/or depression. Methods Electronic searches in eight databases (PubMed/MEDLINE, Scopus, Web of Science, ERIC, PsycINFO, Embase, SciELO and LILACS), using the following keywords: 'Developmental Coordination Disorder,' 'Behavioral Problems,' 'Child,' 'Anxiety,' 'Depression,' 'Mental Health,' and 'Mental Disorders.' The methodological quality was assessed by Newcastle-Ottawa Scale adapted for cross-sectional studies and the NOS for cohort studies. The studies were classified as low, moderate, or high quality. To provide clinical evidence, the effect size of the symptoms of anxiety and depression was calculated for each study. Results The initial database searches identified 581 studies, and after the eligibility criteria were applied, six studies were included in the review. All studies were classified as being of moderate to high quality, and the effect sizes for both anxiety and depression outcomes were medium. The evidence indicated that all of the assessed studies presented more symptoms of anxiety and depression in children with developmental coordination disorder than in their typically developing peers. On the individual level, this review found children with clinical symptoms of anxiety in 17-34% (developmental coordination disorder) and 0-23% (typically developing), and of depression in 9-15% (developmental coordination disorder) and 2-5% (typically developing) of the children. Conclusions Children with developmental coordination disorder are at higher risk of developing symptoms of anxiety and depression than their typically developing peers.

Is Wii-based motor training better than task-specific matched training for children with developmental coordination disorder? A randomized controlled trial.

Purpose: To evaluate in children with developmental coordination disorder (DCD) the effects of Wii-training compared with task-specific matched training (TST).Material and methods: A randomized controlled trial (RCT) was conducted with 32 children having DCD, aged 7-10 years. Children were randomly assigned to the Wii or task-specific training. Both interventions consisted of 16, 60-min sessions over an 8-week period. The primary outcome measure of movement skill was the Movement Assessment Battery for Children-2 (MABC-2), administered by blinded assessors. Measures included total standard scores (TSS), manual dexterity, aiming/catching, and balance component scores.Results: From pre- to post-test, both groups improved significantly on TSS and balance after intervention. The Wii intervention group also improved on manual dexterity. Neither group improved significantly on aiming/catching.Conclusions: Both the Wii and task-specific training improved overall motor performance and balance. On other MABC-2 component scores, treatment effects differed between groups: Task-specific training had more pronounced effects on balance skills, while Wii training had slightly stronger treatment effects than task-specific training on manual dexterity. It was concluded that task-specific training affords stronger benefits for general motor skill than Wii-based training. Whether Wii training can promote clinically significant benefits for upper-limb function remains to be seen.Trial Registration: This study is registered in a clinical trials registry platform (Protocol: RBR-89YDGJ). Available on the Brazilian Clinical Trials Registry Implications for rehabilitationWii-training and task-specific matched training programs afforded gains in motor performance in children with developmental coordination disorder, similarly;The selected Wii tasks were able to improve the motor performance in children with developmental coordination disorder, but should not be used as an exclusive strategy for these children;Our findings suggest caution in recommending Wii-based training as a viable alternative to more task-specific matched training for children with developmental coordination disorder.

Is Segmental Trunk Control Related to Gross Motor Performance in Healthy Preterm and Full-Term Infants?

The authors' aim was to verify the correlation between segmental trunk control and gross motor performance in healthy preterm (PT) and full-term (FT) infants aged 6 and 7 months and to verify if there are differences between groups. All infants were assessed at 6 and 7 months by means of Segmental Assessment of Trunk Control (SATCo) to identify the exact level of segmental trunk control and Alberta Infant Motor Scale (AIMS) to measure gross motor performance. A significant correlation between segmental trunk control and gross motor performance was found in healthy PT infants at 7 months and FT infants at 6 months. PT infants showed a delay on segmental trunk control at 6 and 7 months and in supported standing posture at 6 months compared with FT infants. Segmental trunk control and gross motor performance showed an important relationship in healthy PT and FT infants, mainly in sitting posture.
