EVALUATION OF MANUAL PREHENSION DEVELOPMENT IN CHILDREN BETWEEN FOUR AND TWELVE MONTHS

The objective of this study was to evaluate the development of manual prehension in infants from 4 to 12 months of age who spend most of their time in institutions (private and municipalnurseries), analyzing whether there is a delay in prehension development or not, and what are the possible factors that may be interfering in the development. Evaluation of manual prehension development was not found in the literature, as far as the items analyzed in this study are concerned. Thus, the evaluation was based on the literature considering prehension development and the age of the children. Sixty-eight boys and girls from 4 to 12 months of age were evaluated and divided into three groups: A, B, and C. The results showed that the children from institutions presented a delay in manual prehension development in most of the analyzed items. Taking into account the environment and the routine of these children, it was possible to notice that there was lack of space, toys and tactile and sensory-perceptive stimuli that could help in the acquisition of new prehension and object handling patterns. Physiotherapists, therefore, have an important role in the prevention of this problem. Their job concerns the transmission of their knowledge related to children development, particularly manual prehension, analyzing and observing the needs of each child so that they can interfere, when necessary, and minimize or avoid deficits in children’s manual abilities.Este trabalho teve como objetivo avaliar o desenvolvimento da preensão manual em crianças de 4 a 12 meses de idade institucionalizadas, em berçarios privados e em berçarios municipais, para verificar se existe um atraso no desenvolvimento da preensão e quais os possíveis fatores que podem interferir nesse desenvolvimento. Não foi encontrada na literatura uma avaliação do desenvolvimento da preensão manual em relação aos itens a serem avaliados neste trabalho; desse modo, optou-se por basear tal avaliação na revisão literária relacionando o desenvolvimento da preensão e a faixa etária da criança. Foram avaliadas 68 crianças de 4 a 12 meses de idade, de ambos os sexos, divididas em três grupos. Os resultados mostraram que as crianças institucionalizadas apresentaram um atraso no desenvolvimento da preensão manual na maioria dos itens avaliados. Observando o ambiente e a rotina dessas crianças, pôde-se perceber uma privação de espaço fisico, de brinquedos e de estímulos táteis e senso-perceptivos, o que pode estar interferindo na aquisição de novos padrões de preensão e de manuseio dos objetos. Apontase para a importância do fisioterapeuta, entre outros profissionais da área da saúde, em relação ao desenvolvimento infantil e, em especial, à preensão manual

Measurement of the radiative decay of polarized muons in the MEG experiment

We studied the radiative muon decay $\mu^+ \to e^+\nu\bar{\nu}\gamma$ by using for the first time an almost fully polarized muon source. We identified a large sample (~13000) of these decays in a total sample of 1.8x10^14 positive muon decays collected in the MEG experiment in the years 2009--2010 and measured the branching ratio B($\mu^+ \to e^+\nu\bar{\nu}\gamma$) = (6.03+-0.14(stat.)+-0.53(sys.))x10^-8 for E_e > 45 MeV and E_{\gamma} > 40 MeV, consistent with the Standard Model prediction. The precise measurement of this decay mode provides a basic tool for the timing calibration, a normalization channel, and a strong quality check of the complete MEG experiment in the search for $\mu^+ \to e^+\gamma$ process.Comment: 8 pages, 7 figures. Added an introduction to NLO calculation which was recently calculated. Published versio

Search for the lepton flavour violating decay μ+→ e +γ with the full dataset of the MEG experiment: MEG Collaboration

The final results of the search for the lepton flavour violating decay μ+→ e +γ based on the full dataset collected by the MEG experiment at the Paul Scherrer Institut in the period 2009–2013 and totalling 7.5 × 10 14 stopped muons on target are presented. No significant excess of events is observed in the dataset with respect to the expected background and a new upper limit on the branching ratio of this decay of B(μ+→ e +γ) < 4.2 × 10 - 13 (90 % confidence level) is established, which represents the most stringent limit on the existence of this decay to date
