Percepção viso-motora de escolares com Transtorno do Déficit de Atenção com Hiperatividade

PURPOSE: The aim of this study was to characterize and to compare the visual-motor perception of students with Attention Deficit with Hyperactivity Disorder (ADHD) with students with good academic performance. METHODS: Forty students from 2nd to 5th grades of an elementary public school, male gender (100%), aged between 7 and 10 years and 8 months old participated, divided into: GI (20 students with ADHD) and GII (20 students with good academic performance), paired according to age, schooling and gender with GI. The students were submitted to Developmental Test of Visual Perception (DTVP-2). RESULTS: The students of GI presented low performance in spatial position and visual closure (reduced motor) and inferior age equivalent in reduced motor perception, when compared to GII. CONCLUSION: The difficulties in visual-motor perception presented by students of GI cannot be attributed to a primary deficit, but to a secondary phenomenon of inattention that interferes directly in their visual-motor performance.

Desempenho de escolares com dificuldades de aprendizagem em funçào motora fina e escrita

Aims: the aims of this study were to compare and to characterize the fine, sensory and perceptive function performance and handwritten quality between students with learning difficulties and students with good academic performance. GII, GIII and GIV: 96 students with learning difficulties, and groups GV, GVI, GVII, GVIII: 96 good academic performance. The students were submitted to evaluation of fine motor, sensorial and perception functions and handwriting evaluation under dictation. Results: the results show that the students with learning difficulties from 1st to 3rd grade had lower performance on tests of fine motor, sensory and perceptive function compared to the students with good academic performance in the same grade; the students from 4th grade, both groups, did not show changes on fine motor sensory and perceptive function; and only the students of GII showed disgraphya. Conclusions: the results presented in this study suggest that the qualitative aspects of fine motor, sensory and perceptive skills reflect the integrity and maturity of central nervous system and can probably play an important role in early diagnosis of development disorders and consequently prevent academic disorders such as handwriting performance.

Efeito da intervenção terapêutica ocupacional junto a crianças com déficts de percepção visual, coordenação motora e integração visuo-motora

To students with special educational needs participate actively at school are required effective and systematic investment, involving the school community as a whole. The occupational therapist is one of the professionals who can facilitate this student inclusion process. This study aimed to discuss the occupational therapy intervention effects with two disability children with deficits in visual perceptual skills, motor coordination and visual motor integration, that was included in regular education. The Beery-Buktenica Developmental Test of Visual Motor Integration was use to evaluate visual perceptual skills, motor coordination and visual-motor integration. Because the deficits presented in the functions investigates was identified the need of an occupational therapy intervention program designed to improve the performance in theses functions. After the program, the test was reapplied. The results pointed to an improvement of all functions considered deficient. These results highlight to the training importance to improve the performance in abilities evaluated.

Análise da relação entre a habilidade de integração visuo-motora e o desempenho escolar

Visual-motor integration is a skill that involves visual perception and eye-hand coordination. Deficit in perceptual ability and motor organization capacity may reflect in reading, writing and arithmetic learning difficulties. This study aimed to verify the relationship between visual-motor integration ability and academic performance, as well, whether visual perception ability was correlated with reading performance and whether motor coordination ability was correlated with writing performance. Participants were 77 students in the 2nd. year of elementary education at a public school. To data collect were applied the Developmental Test of Visual-Motor Integration and the Academic Performance Test. The results showed a significant correlation between visual-motor integration ability and academic skills of reading (r = 0.230, p = 0.044), writing (r = 0.244, p = 0.033) and arithmetic (r = 0.277, p = 0.015). In addition, was also identified significant correlation between visual perception and reading performance (r = 0.407, p = 0) and between the motor coordination and cursive writing (p = 0.039). The results of this study are consistent with the literature, concerning the verification of visual-motor integration, visual perception and motor coordination abilities influence on the students performance in school activities.

Respostas da frequência de braçada e do comprimento de braçada na e acima da intensidade correspondente à máxima fase estável de lactato sanguíneo em indivíduos com diferentes níveis de performance

The main objective of this study was to analyze the behavior of variables related to swim ability at and above maximal lactate steady state (MLSS), performed at continuous and intermittent conditions in individuals with different aerobic performance levels. Participated of this study male swimmers with ages between 20 to 25 years, specialists in events of 400 m, 800 m and 1500 m and open water swims, with at least 3 years of experience in the modality. The individuals performed a maximal 400-m swim test. After this test, they were divided into two groups, in accordance with the speed attained during 400-m swim test: G1 (higher performance) and G2 (lower performance). For the determination of continuous MLSS (MLSSc), 2 to 4 trials of 30-min were performed. For the determination of the intermittent MLSS (MLSSi) 2 to 4 trials of 30-min (12 repetitions of 2 min 30 s, with 30 s of rest) were performed, in constant speed, with the first trial performed at 102.5% MLSSc. Th technical indexes, stroke rate (FB) and stroke length (CB) were determined in all tests. The SR was calculated trough recordings using the time needed to perform five stroke cycles. The SL was calculated dividing the speed by the SR. There was no significant difference on the antropometric characteristics between groups. The speed at and above MLSSc were significantly higher at G1 (1,23±0,05 e 1,27±0,06, respectively) than G2 (1,10±0,06 e 1,13±0,06, respectively). There was significant change in SL and SR in G2. In the same way, there was significant change in SL and SR only in G2, above MLSSc. Similar to continuous condition, the speeds at and above MLSSi were significantly higher in G1 (1,27±0,05 e 1,30±0,05, respectively) do que no G2 (1,14±0,07 e 1,16±0,07, respectively). There was significant change in SL and SR only in G2. There was significant change in SR and SL in both groups above MLSSi. Thus,...(Complete abstract click electronic access below)

A coordenação motora de indivíduos com Transtorno do Desenvolvimento da Coordenação (TDC): o ritmo em foco

The aim of the present study was to examine tapping synchronization in children with and without Developmental Coordination Disorder (DCD). Participants were 27 children from which 13 diagnosed with motor difficulties composed the DCD group and 14 children with typical development (TD) the comparison group. The experimental task consisted of performing 25 continuous tapping on a surface of an electronic drum with the preferred hand. Participants were required to tap in synchrony with an auditory bip generated by customized software. Three interval values the tapping task were tested: 470 ms, 1000 ms, 1530 ms. The dependent variables were constant error (CE) and absolute error (AE) and standard deviation of absolute error (SD of AE). The ANOVA 2 x 3 x 3 (Group X Age x Interval) with repeated measures in the last factor for the CE indicated significant interaction among Group X Age X Interval. For the AE and SD of AE the ANOVAs yielded significant main effect of Interval and a significant interaction between Group X Interval. The results of the present study indicated that children with DCD were less accurate and more variable in the tapping synchronization than children with TD. Differences in performance between DCD and children with TD become larger as the interval of the auditory signal increases.

Avaliação dos parâmetros psicomotores de equilíbrio e coordenaçao motora apendicular em crianças obesas

Obesity is a growing problem all over the world, reaching all age groups and social categories. This is a concern ing fact, because the current life style, more and more sedentary, favors the develop of this disease. Children suffer with this ill more and more prematurely and many of its consequences will be carried during all their lives. With the intention of better understand the relationship between obesity and children's motor development, the present research investigated, through psychomotor evaluations of equilibrium and appendicular motor coordination, based on the Exame Neurológico Evolutivo (ENE), the existence of changes in the performance of this variables in obese children and children with normal weight, in their first year on fundamental education in a public state school. The static equilibrium presented itself lower than normal in obese, compared to the normal weight group. Statistically significant differences were not found in respect to dynamic equilibrium and appendicular motor coordination. With that, we can conclude that the static equilibrium suffered influence of obesity, because the centre of gravity might have been changed due to excessive weight

Perfil antropométrico, aptidão motora e aeróbia de jogadores de futebol profissionais e juniores de Trinidad e Tobago

There is little information on Caribbean soccer players. Thus, the aim this study was to descriptive and to compare the anthropometric, motor and aerobic fitness profile between Trinidad and Tobago team professional and junior soccer players. Twenty six soccer players were evaluated (14 professional and 12 junior): anthropometric (height, body mass, BMI, body fat percent), flexibility (sit and reach), velocity (30 m), explosive strength (horizontal and vertical jump), anaerobic power (maximum, mean and minimum power, index of fatigue) and maximum aerobic power. Student Test-t to independent sample was used in statistical analyzes, considering 5% of significance (p<0,05). Results of professional and junior players were, respectively: height (180,6 ± 8,1; 175,0 ± 6,9 cm), body mass (77,1 ± 7,5; 70,6 ± 8,7 kg); BMI (23,6 ± 1,5 / 23,0 ± 1,6 kgm 2 ); body fat (11,9 ± 1,7; 11,6 ± 1,2 %); sitting and reaching (24,9 ± 10,3; 24,9 ± 7,7 cm); velocity (30 m) (4,61 ± 0,14; 4,66 ± 0,15 s); horizontal jump (263,4 ± 14,9; 239,7 ± 12,1 cm); vertical jump (58,7 ± 4,3; 54,6 ± 6,6 cm); maximum power (7,9 ± 0,9; 6,6 ± 0,8 w∙kg-1 ); mean power (6,5 ± 0,7; 5,4 ± 0,9 w∙kg-1 ); minimum power (5,3 ± 0,7; 4,3 ± 1,1 w∙kg-1 ); index of fatigue (33,0 ± 7,9; 34,8 ± 12,8 %); aerobic power (55,0 ± 3,2; 57,2 ± 4,8 ml∙kg-1 ∙min-1 ). Professional players presented higher horizontal jump and maximum, mean and minimum anaerobic power in comparing to the junior players. The highest values of power tests for the lower limbs may be relationship to the longer time of practice in the modality of professional players, which can also indicate a higher level of specialization, which gives priority to the training of power (force and velocity).

Efeitos do conhecimento de resultados autocontrolado na aprendizagem motora

O objetivo do presente estudo foi analisar três diferentes estratégias de fornecer conhecimento de resultados (CR): autocontrolado, yoked pareado por tentativa e yoked pareado pela frequência média total de CR, na prática aleatória. A amostra foi constituída por 45 voluntários universitários, distribuídos em três grupos (n= 15 sujeitos). A tarefa consistiu em pressionar as teclas 2, 4, 8 e 6 do teclado numérico de um computador, em três diferentes tempos alvo (700, 900 e 1100 ms), praticados aleatoriamente. O experimento constou de fase de aquisição e testes de retenção e transferência atrasados. A análise dos dados foi realizada por meio da ANOVA e não foi constatada diferença significativa entre os grupos. Os resultados demonstraram que não houve efeito das frequências autocontroladas para a aprendizagem motora quando se utiliza a prática aleatória. Além disso, uma nova possibilidade de parear o grupo autocontrolado foi apresentada.

Aprendizagem de uma habilidade motora seriada em diferentes estágios de desenvolvimento

Este estudo investigou a aprendizagem de uma tarefa motora seriada em diferentes estágios de desenvolvimento. Quinze crianças, 14 adultos e 13 idosos praticaram a tarefa de rastrear uma sequência de seis estímulos luminosos durante 10 blocos de tentativas ou até descobrir a sequência, constituindo a fase de estabilização e mais dois blocos de tentativas, referentes as fases de adaptação I e II. O desempenho foi mensurado por meio das respostas funcionais e não-funcionais e das sequências funcionais. Os resultados indicaram que os adultos foram superiores aos demais participantes, e idosos apresentaram melhor desempenho que crianças apenas no início da prática, sugerindo que o estágio de desenvolvimento interage com o processo de aprendizagem motora.
