The evaluation of animal locomotor activity is a behavioral tool widely used to measure the mechanisms underlying a particular disease, disorder, or injury, as well as the effects of exposure to a xenobiotic. The elevated beam test is one of the most used tests in rodents to assess balance and motor coordination. Despite being inexpensive and utilizing a simple apparatus, the high beam test requires a long period of animal training and habituation. The development and characterization of an alternative test, namely the gait test, has the potential to circumvent the time and effort required for animal training, deeming it an effective, inexpensive, and fast method for the analysis of behaviors that are comparably assessed by the high beam test. Therefore, the present study focused on determining the effectiveness and feasibility of the gait test for assessing rodent locomotion and balance as a replacement for the elevated beam test. For this purpose, male rats were divided into three groups: one control group exposed to a saline solution (NaCl 0.9%) and two experimental groups exposed to a single dose of either 0.2 or 1.0 mg/kg of ivermectin intraperitoneally for induction of locomotor disturbance. The high beam and gait tests were performed 15 min and 24 h after drug administration. Results show that the experimental groups had difficulty performing the tasks of either test at both time points analyzed compared to the control groups. At the high beam, experimental animals had trouble maintaining balance and walking. At the gait test, experimental animals showed alterations in gait, which were quantitated by: (a) shortening of step length, (b) decrease of stride, (c) altered step symmetry, and (d) altered stride area. Such results are indicative of compensatory efforts and were comparable between both tests. Altogether, the data indicate that the gait test meets all requirements for assessing motor coordination in rodents. The gait test is therefore validated as a complement to the elevated beam test for the study and analysis of neurodegenerative impairment and other disorders involving neuromuscular disturbances.

In the last decades, the use of Item Response Theory (IRT) has been implemented due to the complexity of statistical calculations that allows for in-depth analysis of educational tests, questionnaires and lists of items applied in different areas such as psychometry, sports ranking and pedagogy. Based on this premise, this study aimed to verify the suitability of the KTK motor tasks analyzing the degree of difficulty and discrimination parameters of each motor task. A total of 385 children aged 5 to 14 years participated in the study. The instrument evaluated was the KTK (Körperkoordinationstest für Kinder), consisting of four motor tasks: balance beam, single-pedal jumps, side jumps and platform transposition. Analyzes were conducted from the raw data acquired in each motor task. In order to verify the factor structure of the theoretical matrix underlying the test, an exploratory factor analysis was performed, followed by a confirmatory factor analysis. The difficulty and discrimination parameters of each motor task were analyzed using the gradual response model, based on the Item Response Theory (IRT). The results corroborate the factor structure suggested in the original version of the KTK, presenting only one factor, called motor coordination. The AFC indicators were acceptable, indicating good quality of the model adjusted for the sample. It is concluded that the IRT analysis evidenced differences in the parameters of difficulty and discrimination between the KTK motor tasks, demonstrating the importance of considering a weighting in the creation of normative tables of motor assessments.

School physical education lacks the structuring of its contents. In this sense, its objective was analyzed the effect of structured practice in the teaching of games for the development of coordination with the ball. The sample consisted of 326 students, randomly divided into control groups (CG) and experimental groups (EG) in the various years of basic education. To measure coordination with the ball, TECOBOL (ball coordination test) was used in the pre- and postintervention moments. There were 20 intervention classes in the experimental groups with systematized content and structures, observation in the control groups. To analyze how differences between groups and moments were used, the t-test for independent samples was used, and between the moments of each group, the t-test for paired samples was used. The Effect Size was balanced by Cohen's dm. No significant differences were found between the groups at both times. The size of the effect of structured practice is more effective in experimental groups, especially in the years of elementary school, at age 15. There was a tendency to increase the correlation between coordination with the ball and age with continued practice. Structured practice has more effective gains than practice without prior planning.

Bustamante, E.E, Santiago-Rodríguez, M., Ramer, J.D., Balbim, G.M., Metha, T. & Frazier, S.L. (2019). PENSAR EN MOVIMIENTO: Revista de Ciencias del Ejercicio y la Salud, 17(1), 1-25.Attention-Deficit/Hyperactivity Disorder (ADHD) is characterized by neurodevelopmental delays. Physical activity (PA) may influence many of the same neurocognitive systems affected by ADHD. Therefore, PA may be a potential tool in treatment and management plans. This review synthesizes findings from studies investigating PA, fitness, and motor coordination. Studies of PA in youth on the spectrum for ADHD were considered in this paper. Main results include: a) cross-sectional studies: children with ADHD evidence PA levels higher than children that seem to be healthy. Childhood coincides with opportunities to free play; however, this advantage dissipates by adolescence, as PA programs become increasingly structured and less inclusive. In adulthood, individuals with ADHD are more likely to be obese and less likely to meet healthy lifestyle guidelines; b) longitudinal studies: PA at earlier stages predicts symptom severity in subsequent stages; and c) further studies: moderate PA activity of limited duration offers neurocognitive benefits. Multi-week intervention studies have tested diverse formats with results that differ based upon the chosen outcome and comparison group utilized. PA interventions that challenge cognition and fundamental movement skills in childhood provide benefits to children with ADHD. They also encourage children and adolescents to participate in structured programs, meet PA guidelines, and include short-term AF as part of daily routines.

Objetivo: verificar a relação e a capacidade preditiva do índice de massa corporal, desempenho aeróbio e motor nos diferentes níveis de desempenho da atenção seletiva, flexibilidade cognitiva e velocidade de processamento em crianças. Métodos: trata-se de um estudo transversal realizado em 271 crianças de 6 a 10 anos de idade. Aptidão cardiorrespiratória foi determinada pelo Intermittent Recovery Test – level 1. A coordenação motora foi mensurada pelo teste Körperkoordination für Kinder (KTK), composto por quatro tarefas: trave de equilíbrio, saltos monopedais, transferência sobre plataformas e saltos laterais. Força foi mensurada pelos saltos a 90º e contramovimento. A atenção e flexibilidade cognitiva foram avaliadas pelo teste de atenção por cancelamento (TAC) (atenção seletiva), teste de trilhas A (atenção sustentada) e B (flexibilidade cognitiva), ambos compostos por tarefa de busca visual. Resultado: as crianças de 6 a 8 anos atingiram maiores valores absolutos nos testes TAC total, Tilhas A soma e Trilhas B (sequencia, conexões e soma) Trilhas B-A em comparação as crianças de de 9 a 11 anos (p63,50) e (0,75, >63,50) escore, respectivamente. Conclusão: crianças com maior desempenho aeróbio e motor apresentaram melhores resultados atenção seletiva, atenção sustentada, flexibilidade cognitiva e velocidade de processamento cognitivo em crianças de 6 a 11 anos e estes componentes executivos parecem ser influenciados diretamente pelo IMC e QM, contudo o IMC assemelhou-se de forma negativa.

Objective: This study aimed to determine the ability of different measures of adiposity to discriminate between low/high motor coordination and to evaluate the relationship between different measures of adiposity and motor coordination. Methods: This study included 596 elementary school children aged 9 to 12 years (218 females – 47.1%). Weight, height, and waist circumference were objectively measured by standardized protocols. Body fat percentage was estimated by bioelectric impedance. Body mass index and waist‐to‐height ratio were computed. Motor coordination was assessed by the Körperkoordination Test für Kinder. Cardiorespiratory fitness was predicted by a maximal multistage 20 m shuttle‐run test of the Fitnessgram Test Battery. A questionnaire was used to assess the maternal educational level. Results: The receiver operating characteristic performance of body fat percentage in females and waist circumference in males presented a slightly better discriminatory accuracy than body mass index, waist circumference and waist‐to‐height ratio in predicting low motor coordination. After adjustments, logistic regression analyses showed that body mass index (β = 2.155; 95% CI: 1.164‐3.992; p = 0.015 for girls; β = 3.255; 95% CI: 1.740‐6.088; p

This article postulates that Somatic Education integrates similar issues related to perception in both cognitive science and philosophy. It also indicates that somatic approaches can expand their area of action, overcoming their original role in health maintenance and technical improvement, to reside in the field of research and creation in dance. In order to strength the relationship between dance and somatic education, this article seeks to address some principles of Béziers and Piret’s Motor Coordination study and points out their possible unfolding in research and creation in dance through perception.

Objective: to compare the motor coordination, cognitive, and functional development of preterm and term children at the age of 4 years. Methods: this was a cross‐sectional study of 124 four‐year‐old children, distributed in two different groups, according to gestational age and birth weight, paired by gender, age, and socioeconomic level. All children were evaluated by the Movement Assessment Battery for Children – second edition (MABC‐2), the Pediatric Evaluation of Disability Inventory (PEDI), and the Columbia Mental Maturity Scale (CMMS). Results: preterm children had worse performance in all tests, and 29.1% of the preterm and 6.5% of term groups had scores on the MABC‐2 indicative of motor coordination disorder (p = 0.002). In the CMMS (p = 0.034), the median of the standardized score for the preterm group was 99.0 (± 13.75) and 103.0 (± 12.25) for the term group; on the PEDI, preterm children showed more limited skill repertoire (p = 0.001) and required more assistance from the caregiver (p = 0.010) than term children. Conclusion: this study reinforced the evidence that preterm children from different socioeconomic backgrounds are more likely to have motor, cognitive, and functional development impairment, detectable before school age, than their term peers.

Os propósitos do estudo foram: 1) apresentar valores de referência percentílica às quatro provas da bateria de testes KTK; 2) comparar o desempenho coordenativo entre crianças vouzelenses e de outros estudos do país e exterior; e 3) apresentar pseudo-curvas de velocidade para cada prova. Foram avaliadas 811 crianças com idades entre os seis e os 10 anos. O desempenho coordenativo foi estimado por meio da bateria KTK. Cartas percentílicas e pseudo-curvas de velocidade foram construídas com base no método LMS, implementado no "software" LMSchartmarker Pro versão 2.54. Os valores de referência percentílicas expressam forte variabilidade interindividual do desempenho coordenativo. Em geral, os valores médios vouzelenses são inferiores aos belgas e alemães. O comportamento do percentil 50 das quatro provas do KTK é similar entre Vouzela, Peru e Açores. As pseudo-curvas de velocidade sugerem especificidade em cada prova e sexo, bem como diminuição dos ganhos coordenativos ao longo da idade.The purposes of this study were 1) to construct reference values to KTK test battery; 2) to compare Vouzela children’s motor coordination with those from other Portuguese sites and international references; 3) to present pseudo-velocity curves for each KTK test. The sample comprises 811 children aged six to 11 years. Motor coordination was assessed with the four tests of the KTK Battery. Centile charts were constructed using the LMS method implemented in LMSchartmarker Pro software. Pervasive interindividual differences were noted in all coordination tests. Mean values of Vouzela children’s motor coordination were lower than German and Belgian samples. 50th percentile was similar among Vouzela, Peruvian and Azorean samples. Pseudo-velocity curves suggested a marked specificity to each test and sex, as well as decreasing of the coordinative gains per year.

O propósito deste estudo foi estimar a contribuição dos fatores genéticos e ambientais na variabilidade do desempenho interindividual na coordenação motora. A amostra foi constituída por 64 pares de gêmeos portugueses, com idades entre cinco e 14 anos. Avaliou-se o desempenho da coordenação através das quatro provas da bateria KTK: equilíbrio à retaguarda (ER); saltos monopedais (SM); transposição lateral (TL); saltos laterais (SL). Calculou-se o coeficiente de correlação intraclasse (t), sendo estimada a contribuição dos fatores genéticos (a²), ambientais comuns (c²) e únicos (e²). Os resultados mostram valores de t mais elevados entre gêmeos monozigóticos, sugerindo presença de fatores genéticos. Entretanto, estimativas de a² foram baixas, variando entre 15% (TL) e 41% (SM), enquanto para c² situaram-se entre 46% (SL) e 58% (TL), e para e² entre 11% (SM) e 28% (TL). Conclui-se que fatores ambientais são responsáveis pela maior parcela de influência na variabilidade do desempenho na coordenação motora.El objetivo del presente estudio fue estimar la contribución de los factores genéticos y ambientales en la vEl objetivo del presente estudio fue estimar la contribución de los factores genéticos y ambientales en la variabilidad del desempeño interindividual en la coordinación motora.

Sample comprised 64 twin pairs, aged 5 to 14 years old, from Portugal. Motor coordination was evaluated by KTK battery: backward balance (ER); hopping on one leg (SM); shifting platforms (TL); jumping sideways (SL). Intraclass correlation coefficient (t) was calculated. Contributions of genetic (a²), shared (c²) and unique environmental (e²) factors were estimated. Our results showed t values higher in monozygotic twins, suggesting the presence of genetic factors. Nevertheless, a² estimates were low, ranging from 15% (TL) to 41% (SM), while to common environment (c²) ranged from 46% (SL) to 58% (TL), and unique effects ranged from 11% (SM) to 28% (TL). These results suggest that environmental factors are responsible for the greatest part of influence on variability of interindividual performance in motor coordination tests.

Nowadays, there is growing evidence in literature that Health benefits from regular physical activity (PA). The variance in PA among children is caused by a number of factors including their motor abilities and coordination. The aim of the study was to analyse the relation between usual PA and gross motor abilities and motor coordination in children aged 6 to 7 years. The sample comprised 21 children, aged in average 6,38±0,50 years. Physical activity was accessed by accelerometry, gross motor abilities by using the Test of Gross Motor Development (TGMD-2) and motor coordination by using the Körperkoordination Test für Kinder (KTK). Subjects met the international recommendations for daily PA; in motor coordination 47,6% of children met normal coordination, nobody reach good or very good coordination, the majority (52,4%) revelled disturbances or insufficiencies of coordination; in locomotion TGMD-2 76,2% of the children met percentile 50 or superior (P50), in object control TGMD-2 28,6% of the children reach P50 or superior, in total TGMD-2 38,1% of the children met P50 or superior. PA was positively correlated with TGMD-2 object control. Low performance attributed to the children in TGMD-2 and KTK tests could be an indicative of insufficient in the development of coordination and gross motor abilities; therefore we believe that this kind of intervention should be targeted at school children mainly in Physical Education classes.

Este estudo é percorrido por três principais objetivos: 1) caracterizar o desenvolvimento modal e as diferenças inter-individuais da coordenação motora; 2) verificar a existência de um efeito associado ao gênero; 3) testar a relevância de preditores do desenvolvimento da Coordenação motora (CoM) tais como o IMC e os níveis de Atividade Física. A amostra é constituída de 285 crianças (143 meninos e 142 meninas). A coordenação motora foi determinada a partir da bateria de testes KTK (Equilíbrio em deslocamento para trás, Saltos laterais, Saltos monopedais e Transposição lateral). O questionário de Godin e Shephard (1985) foi utilizado para avaliar a Atividade Física. As estatísticas descritivas básicas foram calculadas no SPSS 15. A mudança intra-individual e as diferenças inter-sujeitos foram efetuadas no programa estatístico HLM, versão 6. É visível um incremento dos valores médios, em ambos os sexos, para as todas as provas do KTK, bem como do IMC e o dos níveis de Atividade Física. Os melhores resultados foram observados nas crianças que estavam no 1º quartil do IMC e no 3º da Atividade Física. Os resultados reafirmam a necessidade de uma estrutura didático-metodologica das aulas de Educação Física para que as crianças alcancem níveis adequados de coordenação para sua idadeThis study aims at: 1) describing models for developmental changes and interindividual differences in gross motor coordination (CoM); 2) verify the presence of gender effects; 3) and test the importance of BMI and physical activity level in motor coordination (CoM) development. Sample size comprises 285 children (143 boys and 142 girls). Motor coordination was evaluated with the test battery "Körperkoordinationstest für Kinder" (KTK) consisting of four tests: backward balance (ER), jumping sideways (SL), hopping on one leg (SM), and shifting platforms (TL). Godin and Shephard's questionnaire was used to evaluate children's physical activity level. Basic statistics were computed in SPSS. Intraindividual changes and interindividual differences were estimated within the framework of multilevel modeling using the HLM software, version 6. Mean significant changes were noticed on both genders in CoM, BMI and physical activity. Best CoM values were found for children in the 1st quartile of BMI and 3rd quartile of physical activity. These results call for a closer attention to novel approaches of didactical issues in the preparation of physical education classes, so that all children may achieve adequate levels of success according to their age

The two main goals of this review were to understand how the relationships between physical activity, physical fitness, somatic fitness, and coordination are established along the motor development of children and adolescents, and how they would influence their future lives. The web based bibliographic database B-On was searched for peer-reviewed publications during the last decade (2000 to 2009). Search criteria included all articles on relationships between any two of the above named factors. Although different methodological designs and variables were found as markers for the same factor, overall results suggested the existence of a clear positive relationship among physical activity, physical fitness, somatic fitness, and coordination from childhood to adolescence, with a special relevance for the relationship between physical activity and coordination. It was also noted a renewed interest on physical activity and motor coordination developmental characteristics and relationships as well as on their lifelong health effects.

Motor and cognitive performance in neurologically healthy adults and older people was examined in a randomsample of 300 individuals from Belo Horizonte, Brazil. Formal schooling ranged from 1 to 25 years, and age variedfrom 18 to 90 years-old. Participants were evaluated through the Paced Auditory Serial Addition Test (PASAT),Nine Hole Peg Test (9-HPT) and Timed Walking of 25 feet (TW-25). Regression analyses showed that ageinfluences motor performance (14% of explained variance for the upper limbs and 11% for the lower limbs), whilecognitive speed was better explained by education (10,6% of explained variance). Receiver-Operating Characteristic(ROC) curves analyses pointed out to a decline in cognitive performance in individuals with lower level of schooling(less than 10 years) and worse motor performance in older individuals (more than 60 years-old). Education and ageare important variables to be taken into consideration in motor and cognitive assessments.

The present study is part of a process of reflection on the relation, relevance and intervention of the body in the musical performance. Considering that the entire performative process demands a unified participation of the instrument, mind and body, it is necessary to deepen the reflection about the perceptions, knowledge and convictions of the faculty, student and professional in the field of music. Given the complementarity between body and performative dimension, it is fundamental to consider the quality that this relationship assumes in the learning processes. Given the objectives of the study, we opted for a methodological conception that allows the articulation of qualitative and quantitative approaches, fundamental to understand, describe and interpret the different representations / perceptions of the participants. In this way, the questionnaire survey (Questionnaire I and II) was directed to the faculty and students of the area of music of the Federal University of Rio de Janeiro and researchers of the Brazilian Association of Musical Performance. The obtained results show that the differentiated coordination and the body movements assume an essential condition for the musician and his performance. [ABSTRACT FROM AUTHOR]

One of the objectives of physical education classes is to enable students to involve diverse perceptual-motor experience necessary for the development of functional and adaptive behaviors. In this sense, this paper aims to identify students in the elementary school with difficulties coordinative in a particular school of Ilhéus (BA) and check your connection with the participation in Physical Education classes. The results showed that students with indicative of atypical coordinative development were less participatory in Physical Education classes. The discussion was focused on the implications for teacher practice, providing some directions for the organization and development of innovative practices in Physical Education.

The main clinical signs observed in the poisoning by Ipomoea asarifolia are intention tremors and incoordination. The aim of this study was to determine if I. asarifolia is tremorgenic for mice and its effect on equilibrium, coordination and muscle strength. Three groups Swiss male mice received ration containing 0, 20% and 30% of dry I. asarifolia for 30 days. On day 0 and every fi ve days feed and water intake and the weight of the animals were measured. At the same time the animals were tested for equilibrium, coordination and muscle strength on the elevated bar, wire suspension and rota-rod. Changes in balance and motor coordination were observed in the elevated bar and the rotarod, suggesting that the plant affects the central nervous system. However, muscle tremors were not observed.

The aim of this study was to evaluate the effect of hand and foot preferences, sex and age on motor co-ordination (MC) in children. We evaluated the hand preference (HP) through the Card-reaching task (Carlier et al., 2006, adapted from Bishop et al., 1996) and the Dutch Handedness Questionnaire (Van Strien, 2002). Foot preference (FP) was evaluated inviting the subjects to kicking a ball (Hart & Gabbard, 1996). We applied the Movement Assessment Battery for Children MC test (Henderson & Sugden, 1992) to 319 children (7.96 ± 2.38 y). The results show that right handers have better performance on manual dexterity (MD) and ball skills (BS) with their preferred hand (PH). Left-handers perform better with their non-preferred hand (NPH) in MD and have a better static balance (SB) with your non-preferred foot (NPF). Girls had better MD with NPH and better SB with NPF. We observed a better MD performance with PH and NPH, BS with NPH and SB with the PF and NPF in the younger children. PHxAge and MpxAgexSex interactions were also verified. It can be concluded that the laterality, sex and age have significant effects on children MC. [ABSTRACT FROM AUTHOR]
