Estudio sobre la amplitud del movimiento articular de la rodilla en el proceso de marcha de niños con parálisis cerebral espástica

Introduction: To analyze the contribution of knee range of motion in walking of hemiplegic and diplegic children, considering their asymmetries. Material and method: Twelve children, 6 hemiplegics and 6 diplegics, from 7 to 12 years of age (9.5 ± 1.93) participated. Spasticity was assessed with the Ashworth's Modified Scale and the passive knee range of motion using an electrogoniometer. The task was to walk on an 8 m long walkway, using their preferred speed. Six attempts were made, three of which were on the right and three on the left sagittal planes. Results: The Mann-Whitney's U test found differences in the type of cerebral palsy for knee extension/hyperextension, for the relative angle of the knee at the load acceptance phase and for the knee range of motion during stride. The Wilcoxon's test revealed differences in hemibody for hemiplegics in the relative angle of the knee in acceptance of the load. Conclusions: Children with spastic cerebral palsy use compensation strategies between the lower limbs during walking. These strategies differed according to the type of cerebral palsy. The knee joint has an important function in those strategies, especially in the load acceptance and propulsion phases. © 2010 Elsevier España, S.L. y SERMEF. Todos los derechos reservados.

Measurement of the semileptonic charge asymmetry in B0 meson mixing with the D0 detector

We present a measurement of the semileptonic mixing asymmetry for B0 mesons, asld, using two independent decay channels: B0→μ +D -X, with D -→K +π -π -; and B0→μ +D *-X, with D * -→D ̄0π -, D ̄0→ K +π - (and charge conjugate processes). We use a data sample corresponding to 10.4fb -1 of pp̄ collisions at √s=1.96TeV, collected with the D0 experiment at the Fermilab Tevatron collider. We extract the charge asymmetries in these two channels as a function of the visible proper decay length of the B0 meson, correct for detector-related asymmetries using data-driven methods, and account for dilution from charge-symmetric processes using Monte Carlo simulation. The final measurement combines four signal visible proper decay length regions for each channel, yielding asld=[0.68±0.45(stat)±0.14(syst)]%. This is the single most precise measurement of this parameter, with uncertainties smaller than the current world average of B factory measurements. © 2012 American Physical Society.

Forward-backward asymmetry of Drell-Yan lepton pairs in pp collisions at s=7TeV

A measurement of the forward-backward asymmetry (AFB) of Drell-Yan lepton pairs in pp collisions at s=7TeV is presented. The data sample, collected with the CMS detector, corresponds to an integrated luminosity of 5fb-1. The asymmetry is measured as a function of dilepton mass and rapidity in the dielectron and dimuon channels. Combined results from the two channels are presented, and are compared with the standard model predictions. The AFB measurement in the dimuon channel and the combination of the two channels are the first such results obtained at a hadron collider. The measured asymmetries are consistent with the standard model predictions. © 2012 CERN.

Propulsive force asymmetry during tethered-swimming

This study aimed to determine whether: i) tethered-swimming can be used to identify the asymmetry during front crawl swimming style; ii) swimmers that perform unilateral breathing present greater asymmetry in comparison to others that use bilateral breathing; iii) swimmers of best performance present smaller asymmetry than their counterparts; iv) repeated front crawl swimming movements influence body asymmetry. 18 swimmers were assessed for propulsive force parameters (peak force, mean force, impulse and rate of force development) during a maximal front crawl tethered-swimming test lasting 2 min. A factorial analysis showed that propulsive forces decreased at the beginning, intermediate and end of the test (p<0.05), but the asymmetries were not changed at different instants of the test. When breathing preference (uni- or bilateral) was analyzed, asymmetry remained unchanged in all force parameters (p>0.05). When performance was considered (below or above mean group time), a larger asymmetry was found in the sub-group of lower performance in comparison to those of best performance (p<0.05). Therefore, the asymmetries of the propulsive forces can be detected using tethered-swimming. The propulsive forces decreased during the test but asymmetries did not change under testing conditions. Although breathing preference did not influence asymmetry, swimmers with best performance were less asymmetric than their counterparts. © Georg Thieme Verlag KG Stuttgart New York.
