RESUMO

The benefits of allowing learners to control when to receive knowledge of results (KR) compared to a yoked group has been recently challenged and postulated to be mild at best. A potential explanation for such dissident findings is that individuals differentially utilize the autonomy provided by the self-controlled condition, which, in its turn, affects the outcomes. Therefore, the present study investigated the effects of self-controlled KR on motor learning focusing on the frequency of KR requests when performing an anticipatory timing task. Self-controlled groups were created based on participants' KR frequency of request (High, Medium, and Low referring to fifth, third, and first quintile) and, then, Yoked groups were created self-control condition pairing the KR request of the Self-controlled groups. We also measured self-efficacy and processing time as means to verify potential correlates. The results supported the expected interaction. While no difference between self-controlled and yoked groups were found for low frequencies of KR, a moderate amount of KR request was related to better results for the self-controlled group. Nonetheless, the opposite trend was observed for high frequencies of KR; the yoked group was superior to the self-controlled group. The results of this study allow us to conclude that the choices made, and not just the possibility of choosing, seem to define the benefits of KR self-control in motor learning.

RESUMO

BACKGROUND: Sensory information obtained from the visual, somatosensory, and vestibular systems is responsible for regulating postural control, and if damage occurs in one or more of these sensory systems, postural control may be altered. OBJECTIVE: To evaluate and compare the postural sway velocity between children with normal hearing and with sensorineural hearing loss (SNHL), matched by sex and age group, and to compare the postural sway velocity between children with normal hearing and with SNHL, with and without vestibular dysfunction. METHODS: Cross-sectional study that evaluated 130 children (65 with normal hearing and 65 with SNHL), of both sexes and aged between 7 and 11 years, from public schools of the city of Caruaru, Pernambuco state, Brazil. The postural sway velocity of the center of pressure (COP) was assessed by a force platform, in two directions, anteroposterior (AP) and mediolateral (ML)), in three positions, namely bipedal support with feet together and parallel (parallel feet (PF)), bipedal support with one foot in front of the other (tandem foot (TF)), and single-leg support (one foot (OF)), evaluated with the eyes open and closed. RESULTS: Children with SNHL demonstrated greater postural sway velocity compared to children with normal hearing in all the positions evaluated, with significant differences in the AP direction, with the eyes open (PF: p = 0.001; TF: p = 0.000; OF: p = 0.003) and closed (PF: p = 0.050; TF: p = 0.005). The same occurred in the ML direction, with the eyes open (PF: p = 0.001; TF: p = 0.000; OF: p = 0.001) and closed (PF: p = 0.002; TF: p = 0.000). The same occurred in relation to vestibular function, where the children with SNHL with an associated vestibular dysfunction demonstrated greater postural sway velocity compared to children with normal hearing in all the positions evaluated, demonstrating significant differences in the AP direction, with the eyes open (TF: p = 0.001; OF: p = 0.029) and eyes closed (PF: p = 0.036; TF: p = 0.033). The same occurred in the ML direction, with the eyes open (TF: p = 0.000) and with the eyes closed (PF: p = 0.008; TF: p = 0.009). CONCLUSIONS: Children with SNHL demonstrated greater instability of postural control than children with normal hearing in all the directions assessed. Children with SNHL and an associated vestibular dysfunction demonstrated the greatest instability of postural control in this study.

The research was applied, approached from the quantitative approach and quasi-design experimental. 107 students from the 6th grade of primary school participated in two groups; The Corporeity Program was applied only to the experimental group through 15 sessions in the postural perception and mobile perception and regulation dimensions. The MOBAK Battery 5-6 was applied, measuring two basic motor skills: control of objects and control of the body. The results establish that both groups (control and experimental) in the pretest do not reflect significant differences in the achievement of basic motor skills (0.170 ≥ 0.05). Likewise, it was evidenced that both groups (control and experimental) in the post-test do reflect significant differences (0.000 < 0.05), finding that the average range of the control group is 27.51 and of the experimental group notoriously higher with 73.98, giving a value for the Mann-Whitney U test of 184,500; concluding that the application of the Corporeity Program did have a significant effect on the acquisition of basic motor skills in primary school students.

RESUMO

The development of motor competence is thought to be a crucial precursor to raising the trajectory of PA throughout a person's life. The objectives of this study are to determine motor competence and the daily time of moderate and vigorous physical activity of students in 5th and 6th grade elementary in Chile, and to establish whether there are differences in motor competence according to sex and compliance with physical activity recommendations. 368 schoolchildren (M = 11.10 years; 54.3% girls) participated. To assess motor competence, the MOBAK 5-6 test was used. Physical activity was measured using ActiGraph wGT3X-BT® accelerometers. Boys (M = 3.65, SD = 2.14) showed better performance than girls (M = 2.39, SD = 1.80) in Object Control (p ≤ 0.001, PS = 0.67). For Self-Movement, the girls (M = 2.72, SD = 2.14) performed better than the boys (M = 2.40, SD = 1.86); however, there were no significant differences between the two sexes (p = 0.257). Boys (M = 48.4, SD = 22.8) presented more daily minutes of moderate and vigorous physical activity than girls (M = 35.9, SD = 16.9), with statistically significant differences (p ≤ 0.001, PS = 0.67). About MC according to compliance with the physical activity recommendations, only in Object Control there is a statistically significant difference (p ≤ 0.001; PS = 0.29) between the students who comply with the recommendations (M = 4.28, SD = 2.12) and those who do not achieve the recommended minutes (M = 2.67, SD = 1.29). By contrast, an analysis of Self-Movement found no significant difference (complies: M = 2.73, SD = 1.97; does not comply: M = 2.54, SD = 2.04; p = 0.408) between the two groups. It is necessary to generate instances that develop motor competence in all its dimensions to promote higher levels of moderate to vigorous physical activity.

RESUMO

This study aimed to review the prevalence of developmental coordination disorder (DCD) in individuals born preterm and systematically explore this prevalence according to gestational age and different assessment cut-offs and compare it to full-term peers. The eligibility criteria were observational and experimental studies reporting the prevalence of DCD in preterm individuals. A systematic search was performed in databases from inception until March 2022. Two independent reviewers performed the selection. Study quality assessment was performed using the checklists from Joanna Briggs Institute (JBI). Data analysis was performed on Excel and Review Manager Software 5.4. Among the 1774 studies identified, 32 matched the eligibility criteria. The pooled estimate rate of the DCD rate in preterm was 21% (95% confidence interval [CI] 17.8-24.3). The estimate rates were higher as gestational age decreased, and preterm children are two times more likely to have DCD than their full-term peers risk ratio (RR) 2.2 (95% CI 1.77-2.79). The limitation was high heterogeneity between studies; the assessment tools, cut-off points and age at assessment were diverse. This study provided evidence that preterm children are at higher risk for DCD than full-term children, and the risks increased as gestational age decreased.

RESUMO

BACKGROUND: Children with Down syndrome (DS) demonstrate poorer performance in locomotor and ball skills than children with typical development. During motor assessment, keeping children's attention and motivation is challenging, especially for children with DS, which may affect the test outcomes. This study aimed first to examine the impact of examiner and App-animation demonstrations during the assessment on the performance of fundamental motor skills, focus of attention and intrinsic motivation for children with DS and neurotypical development (NTD). The secondary aim was to examine the differences in those outcomes between children with DS and neurotypical development. METHODS: A sample of 24 children (10 with DS and 14 with NTD) aged between 3 and 10 years were subjected to two motor performance assessment protocols: a traditional protocol using the Gross Motor Development Test-3 (TGMD-3) and a protocol using animations from an application as support for TGMD-3 (AppP). The focus of attention was obtained from video recordings during protocol instruction (number of eye shifts, eye shift time, instruction focus time, number of instructions required and total instruction time). Intrinsic motivation was assessed by the Intrinsic Motivation Inventory (IMI) at the end of each protocol. RESULTS: The results showed no significant differences between the protocols for locomotor skills, ball skills and gross motor index. However, children with NTD outperformed those with DS in these skills. When analysing the focus of attention, children with DS showed greater ocular deviations and longer instruction time requested in the traditional protocol compared with AppP, even when compared with NDT children. When comparing protocols in both groups, AppP demonstrated fewer ocular deviations and shorter ocular deviation times. Regarding intrinsic motivation, children with DS in the traditional protocol had lower motivation scores than those with NTD. Regarding the purchase of protocols, in both groups, the AppP presented higher scores for interest/pleasure, perceived competence and general motivation, with lower pressure/tension. CONCLUSION: The animated application (AppP) proved effective as a visual support during the TGMD-3 assessment, particularly benefiting children with DS by enhancing motivation and attention.

RESUMO

OBJECTIVE: To synthesize evidence about physical fitness levels in children with developmental coordination disorder (DCD) compared with typically developing (TD) children. METHODS: 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. RESULTS: 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. CONCLUSION: Children with DCD presented significantly lower physical fitness than their typically developing peers, particularly in aerobic and anaerobic capacity and in muscle strength.

RESUMO

BACKGROUND: Developmental coordination disorder (DCD) is a neurodevelopmental disorder characterized by deficits in performing motor tasks. Research suggests social skills are also altered. OBJECTIVE: To investigate (1) whether the presence of DCD affects social responsiveness, (2) whether the co-occurrence of autism spectrum disorder (ASD) affects social responsiveness in children with DCD, and (3) whether there is an association between motor performance and social responsiveness in children with DCD. METHODS: Based on parental reports, children aged 5 to 15.5 years were assigned to one of three groups: DCD only (noASD, n = 67), DCD and suspected ASD (sASD, n = 13), and DCD and confirmed ASD (cASD, n = 22). Parental answers to the Social Responsiveness Scale (SRS-2) and the DCD-Questionnaire (DCD-Q) were compared to norm values using one sample t-tests, and between groups using ANOVA and MANOVA. Pearson correlation coefficients explored the relationship between the SRS-2 and DCD-Q in the total group and per group. RESULTS: Compared to norm values, difficulties in all areas of social responsiveness were reported in children with DCD, regardless of group (p<0.001). Compared to the noASD group, more unfavorable SRS-2 total T-scores and poorer DCD-Q scores were observed in sASD and cASD groups. Only in the total group, motor performance showed significant weak to moderate associations with the SRS-2 total T-score and all subscales except for 'social motivation' (r=-0.306 to -0.405; p ≤ 0.02). CONCLUSION: Social responsiveness difficulties are more common in children with DCD and are more severe in the ASD groups. Motor performance and social responsiveness are weak to moderately associated. CLINICAL TRIAL REGISTRATION NUMBER: NCT05092893 (https://clinicaltrials.gov/study/NCT05092893).

RESUMO

Abstract Background The application of botulinum toxin (BoNT) in the treatment of blepharospasm and hemifacial spasm (HS) is a well-established practice. However, neurology residency programs often rely on real patients for training, which has limitations in terms of patient availability and skill acquisition. Objective Assess the efficacy of a new facial phantom model for acquiring motor skills in BoNT application. Methods An anthropomorphic facial phantom model was developed in collaboration with a medical training simulator start-up. A group of seven neurologists and one ophthalmologist with expertise in BoNT application evaluated the model using an adapted learning object review instrument (LORI). The instrument assessed aspects such as: content quality, alignment of learning objectives, feedback and adaptation, motivation, presentation design, and accessibility. Results The facial phantom model received high scores in the LORI evaluation, with the highest ratings given to alignment with learning objectives and motivation. The model also scored well in terms of accessibility, content quality, and presentation design. However, feedback and adaptation received a lower score due to the static nature of the model. Conclusion The facial phantom model shows promise as a valuable tool for teaching and developing competence in BoNT application for HS and blepharospasm. The model reduces the reliance on real patients for training, providing a broader and safer learning experience for neurology residents. It also provides a realistic learning experience and offers portability, cost-effectiveness, and ease of manufacturing for use in various medical training scenarios. It is an effective and accessible tool for teaching BoNT application.

Resumo Antecedentes A aplicação de toxina botulínica (TxB) no tratamento do blefaroespasmo e do espasmo hemifacial (EH) é uma prática bem estabelecida. No entanto, os programas de residência em neurologia frequentemente dependem de pacientes reais para treinamento, o que apresenta limitações em termos de disponibilidade de pacientes e aquisição de habilidades. Objetivo Avaliar a eficácia de um novo modelo de manequim facial para aquisição de habilidades motoras na aplicação de TxB. Métodos Foi desenvolvido um modelo antropomórfico de manequim facial em coloboração com uma empresa de simuladores de treinamento médico. Um grupo constituído por sete neurologistas e um oftalmologista com experiência em aplicação de TxB avaliou o modelo utilizando um instrumento adaptado de revisão de objeto de aprendizagem (LORI). O instrumento analisou aspectos como: qualidade do conteúdo, alinhamento dos objetivos de aprendizagem, feedback e adaptação, motivação, concepção da apresentação e acessibilidade. Resultados O modelo de manequim facial obteve pontuações altas na avaliação do LORI com os maiores escores em alinhamento com os objetivos de aprendizagem e motivação. O modelo também obteve boas pontuações em termos de acessibilidade, qualidade do conteúdo e concepção da apresentação. No entanto, o item feedback e adaptação recebeu uma pontuação média mais baixa, devido à natureza estática. Conclusão O modelo manequim facial mostra-se promissor como uma EH e blefaroespasmo. O modelo reduz a dependência de pacientes reais para treinamento portátil, de baixo custo e de fácil fabricação para uso em diversos cenários de treinamento, proporcionando uma experiência de aprendizagem mais ampla e segura para residentes de neurologia. Além disso, fornece uma experiência de aprendizagem realista e oferece portabilidade, economia e facilidade de fabricação para uso em vários cenários de treinamento médico. É uma ferramenta eficaz e acessível para o ensino da aplicação de TxB.

RESUMO

ABSTRACT Motor development during childhood is fundamental for acquiring advanced perceptual and cognitive skills, playing a pivotal role in personal development and skill acquisition later in life. This study aims to investigate differences in the motor skills of children between the ages of 3 to 5, based on their geographic location (urban or rural) and gender. A cohort of 94 Portuguese children between the ages of 3 and 5 years old (comprising 48 boys and 46 girls) were selected for a study. Data collection was conducted within 8 different schools, and motor skills were assessed utilizing the MOBAK-KG test. It was observed that children from urban areas outperformed those from rural areas in motor skills related to body and object control. On the contrary, girls' motor skills did not show significant differences according to their geographical location. Although the geographical environment influences children's motor development, other factors, such as socio-economic and cultural factors, may have a greater impact on girls. These findings emphasise the significance of focusing on the motor development of girls and examining how cultural and gender expectations can impact their motor skills.

RESUMO O desenvolvimento motor durante a infância é fundamental para a aquisição de competências perceptivas e cognitivas avançadas, desempenhando um papel fulcral no desenvolvimento pessoal e na aquisição de competências mais tarde na vida. Este estudo tem como objetivo investigar as diferenças nas capacidades motoras de crianças entre os 3 e os 5 anos de idade, com base na sua localização geográfica (urbana ou rural) e género. Foi selecionada para o estudo uma coorte de 94 crianças portuguesas com idades compreendidas entre os 3 e os 5 anos (48 meninos e 46 meninas). A recolha de dados foi efectuada em 8 escolas diferentes e as capacidades motoras foram avaliadas utilizando o teste MOBAK-KG. Verificou-se que as crianças das zonas urbanas superavam as das zonas rurais nas capacidades motoras relacionadas com o controlo do corpo e dos objectos. Pelo contrário, as capacidades motoras das raparigas não apresentaram diferenças significativas em função da sua localização geográfica. Embora o ambiente geográfico influencie o desenvolvimento motor das crianças, outros factores, tais como os factores socioeconómicos e culturais, podem ter um maior impacto nas raparigas. Estes resultados sublinham a importância de nos concentrarmos no desenvolvimento motor das raparigas e de examinarmos a forma como as expectativas culturais e de género podem ter impacto nas suas capacidades motoras.

ABSTRACT This systematic review aims to identify and summarize studies that analyzed the effects of interventions that used sports teaching models (STM) in physical education classes on cognitive and motor skills outcomes. Six bases were defined as data sources: (a) SportDiscus; (b) Scielo; (c) Web of Science; (d) Scopus; (e) ERIC and (f) PsycInfo. The initial search was carried out with the following terms: "Pedagogical Model" OR, "Education Model", OR, "Teaching Games" AND, "Sports" AND, "Physical Education". The 24 articles analyzed met the following criteria: (a) intervention studies with quantitative or mixed analysis; (b) performed during physical education classes; and, (c) aim to verify the effects of STM on cognitive or motor skills outcomes. The analysis of bias/quality of the studies was performed based on the PEDro scale. Interventions were found with the Sport Education Model (SEM - 41.7%), Teaching Games for Understanding (TGfU - 33.3%), Tactical Games (TG - 4.2%) and Hybrid Models (HM - 20.8%). The results indicate positive effects of the three models (SEM, TGfU/TG and HM) on game performance and decision-making. SEM still had a positive effect on game involvement, knowledge and skill execution, with STM with more outcomes with positive results. Future investigations should consider intervening factors such as sex, skill level, teaching groups, teacher experience, time and unit content.

RESUMO

Abstract This study aimed to examine the relative age effect on muscle power in a large sample of Brazilian children and adolescents. The sample consisted of 87,766 girls and boys aged 7-16 years, data collected in repeated cross-sectional surveillance carried out since 1999. The participants were grouped into four age subgroups within each chronological age based on birthdates. Upper and lower limbs muscle power were assessed using the 2-Kg medicine ball throw and horizontal jump tests, respectively. The normative distribution of physical fitness components was used for classification. The results showed a significant association between relative age and normative classification of muscle power. Among boys, there was a sequential increase in the frequency of individuals classified as "very good/excellent" as the relative age increased. A similar trend was observed among girls. The findings provided evidence of a relative age effect on muscle power in Brazilian children and adolescents. These findings have implications for the organization of structured physical activities and sports, as early-born individuals may have an advantage in performance. Further research is needed to explore the underlying mechanisms and potential interventions to mitigate the relative age effect and promote equal opportunities for all youth in physical activities and sports.

Resumo Este estudo teve como objetivo examinar o efeito da idade relativa na potência muscular em crianças e adolescentes brasileiros. A amostra foi composta por 87.766 meninas e meninos com idades entre 7 e 16 anos. Os participantes foram agrupados em quatro subgrupos etários dentro de cada idade cronológica tendo como base as datas de nascimento e da coleta dos dados. A potência muscular dos membros superiores e inferiores foi avaliada por meio dos testes de arremesso de medicine ball de 2 kg, e salto horizontal, respectivamente. A distribuição normativa (fraco; razoável; bom; muito bom; excelente) dos dois testes de potência foi utilizada para a classificação. Os resultados mostraram associação significativa entre os subgrupos etários e a classificação normativa da potência muscular. Entre os meninos, houve aumento na frequência de indivíduos classificados como "muito bom/excelente" à medida que a idade relativa aumentava. Uma tendência semelhante foi observada entre as meninas. Os achados forneceram evidências do efeito de idade relativa na potência muscular de crianças e adolescentes brasileiros. Esses resultados têm implicações práticas na organização de atividades físicas estruturadas e esportes em diferentes contextos, pois indivíduos nascidos mais cedo podem ter vantagem no desempenho em tarefas que exijam potência muscular. Mais pesquisas são necessárias para explorar os mecanismos subjacentes e intervenções que possam mitigar o efeito de idade relativa e promover oportunidades iguais para todas as crianças e adolescentes nas atividades físicas e esportes.

RESUMO

Purpose: The purpose of this study is to assess whether the Dunning-Kruger effect occurs in surgical residents when performing laparoscopic cholecystectomy in a porcine model. Methods: Prospective blinded study, which counted with forty PGY-1 general surgery residents who agreed to participate in the study were blindly recruited to perform a laparoscopic cholecystectomy in a porcine model. At the end of the procedure, the participants assigned a score of 0-10 for their own performance and the video of the operation was independently assessed by 2 experienced laparoscopic surgeons using a validated tool. Results: Participants were divided into groups of 10 individuals according to objective performance and compared. The group with the worst objective result was inferior to the group with the best objective result (3.77 ± 0.44 vs. 8.1 ± 0.44, p < 0.001), but they were similar in self-perception of performance (5.11 ± 1.69 vs. 6.1 ± 1.79, p = 0.999). Conclusions: In the studied sample, it was possible to demonstrate the presence of the Dunning-Kruger effect.

RESUMO

Introduction: Motor compromise characterizes cerebral palsy (CP), and is often associated with intellectual disability (ID). Standardized classification systems have been developed to describe the functions of people with CP. The aim was to functionally characterize children and adolescents aged 0 to 18 years with CP in Argentina and to investigate the association between motor compromise (GMFCS), ID and functional classifications. Methods: Cross-sectional study. Data were collected through family interviews and medical records review. Individuals with CP were included. Data were collected from 19 institutions in different cities of Argentina. Fisher's test and odds ratio [IC95%] were used for data analysis, with significance <0.05. Results: 182 children and adolescents with CP participated. According to GMFCS classification, level V prevailed with 36.3%. Those with more severe motor compromise (GMFCS IV-V) were 72 [25.4;206.0] times and 13 [5.9;28.2] times more likely to present a severe level of MACS and CFCS, respectively. But they were 34 [7.9;146.0] times more likely to have a mild to moderate level of EDACS. Those with DI were 10 [5.1;20.5] times more likely to have severe GMFCS, 6 [3.4;13.2] times more likely to have severe MACS and 4 [2.0;7.8] times more likely to have severe CFCS. On the contrary, they are 4 [1.9;9.5] times more likely to present a mild-moderate EDACS level. Conclusion: the level of GMFCS and the presence of DI influence general functionality and increase severity in engagement, manual and communication skills.

Introducción: El compromiso motor caracteriza la parálisis cerebral (PC), y suele asociarse a la discapacidad intelectual (DI). Se han desarrollado sistemas de clasificación estandarizados para describir las funciones de personas con PC. Objetivo: caracterizar funcionalmente a niños, niñas y adolescentes de 0 a 18 años con PC de Argentina e indagar la asociación entre el compromiso motor (GMFCS), la DI y las clasificaciones funcionales. Métodos: Estudio transversal. Se recolectaron datos a través de entrevistas a las familias y revisión de historias clínicas. Se incluyeron personas con PC. Los datos se recolectaron de 19 instituciones de distintas ciudades de Argentina. Resultados: participaron 182 niños, niñas y adolescentes con PC. Según clasificación GMFCS prevaleció el nivel V con 36,3%. Quienes presentan compromiso motor más severo (GMFCS IV-V), tienen 72 [25,4;206,0] veces y 13 [5,9;28,2] veces más chances de presentar un nivel severo de MACS y CFCS respectivamente. Pero, presentaron 34 [7,9;146,0] veces más chances de un nivel leve a moderado de EDACS. Quienes presentaron DI tuvieron 10 [5,1;20,5] veces más chances de presentar un nivel severo GMFCS, 6 [3,4;13,2] veces más chances un nivel severo MACS y 4 [2,0;7,8] veces más chances de un nivel severo CFCS. Por el contrario, tienen 4 [1,9;9,5] veces más chances de presentar un nivel leve-moderado EDACS. Conclusión: el nivel de GMFCS y la presencia de DI influyen en la funcionalidad general y aumentan la severidad en el compromiso, habilidades manuales y de comunicación.

RESUMO

Fundamento: la coordinación motriz ha sido y será uno de los componentes más importantes en el área de educación física, pues permite sincronizar y coordinar los movimientos de los músculos y de las extremidades del cuerpo, a fin de posibilitar la realización de diversas actividades. Objetivo: determinar el nivel de coordinación motora diferenciada por edades y sexos en escolares. Métodos: investigación realizada en la Institución Educativa Mariano Ospina Rodríguez, que incluyó escolares de seis a once años de edad, a los que se aplicó el test 3JS, el cual consta de una batería de siete pruebas para determinar el nivel de coordinación motora en los niños. Resultados: existieron diferencias muy significativas al comparar la coordinación motora de los niños con respecto a todos los rangos de edades estudiados (6-7 años vs 8-9 años; 6-7 años vs 10-11 años; 8-9 años vs 10-11 años) (p<0,01). Las niñas obtuvieron diferencias muy significativas al comparar los grupos de 6-7 años con respecto al de 8-9 años y 10-11 años (p<0,01); sin embargo, al comparar niños y niñas por rangos de edades, solamente el grupo de 10-11 años presentó diferencias significativas en la coordinación motora (p<0,01). Conclusiones: los resultados permiten inferir que es importante evaluar y desarrollar actividades acordes a la etapa de maduración del niño y determinar trabajos más específicos para las niñas, puesto que en este trabajo y en muchos estudios realizados se identificó una diferencia significativa en cuanto a su desarrollo motor.

Foundation: motor coordination has been and will be one of the most important components in the physical education area, since it allows synchronizing and coordinating the muscles movements and extremities of the body, in order to enable the performance of various activities. Objective: to determine the motor coordination level differentiated by age and sex in schoolchildren. Methods: research carried out at the Mariano Ospina Rodríguez Educational Institution, which included schoolchildren from six to eleven years of age, to whom the 3JS test was applied, which consists of seven tests battery to determine the motor coordination level in children. Results: there were very significant differences when comparing the children motor coordination regarding all the age ranges studied (6-7 years vs 8-9 years; 6-7 years vs 10-11 years; 8-9 years vs 10 -11 years) (p<0.01). The girls obtained very significant differences when comparing the groups of 6-7 years with respect to that of 8-9 years and 10-11 years (p<0.01); however, when comparing boys and girls by age range, only the 10-11 year old group presented significant differences in motor coordination (p<0.01). Conclusions: the results allow us to infer that it is important to evaluate and develop activities according to the child maturation stage to determine more specific jobs for girls, since in this work and in many studies carried out, a significant difference was identified in terms of their motor development.

RESUMO

This study aimed to explore motor trajectories of Brazilian pre-term and full-term infants from 3 to 12 months old whose parents participated in an educational program and had received guidance on gross motor development. Forty-eight Brazilian infants aged 3 months old were divided into Group 1 (full-term infants and their parents who received only verbal guidance, n = 14), Group 2 (full-term infants with parents who received an educative folder in addition to the same verbal guidance, n = 23), and Group 3 (preterm infants with parents who received the same verbal guidance and educative folder, n = 11). The folder had similar information to the verbal guidance; nonetheless, it helped to teach parents and allowed later consultation at home. We applied Alberta Infant Motor Scale, Affordances in Home Environment for Motor Development-Infant Scale, and a questionnaire about infants' information at 3-, 6-, 9-, and 12-months old. In longitudinal comparison, all groups showed a significant difference for AIMS variables on total score and subscales; all subitems of AHEMD-IS; and time spent in prone, supine, sitting, and standing positions. In general, no differences were found between groups. Motor trajectory, home opportunities, and parental positioning practices were similar between full-term and preterm infants with different guidance approaches.

RESUMO

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.
