Correlação entre equilíbrio, assimetria de passos e descarga de peso em indivíduos hemiparéticos

Introduction: Hemiparesis is the most common sequels after Stroke. One of the side effects of the motor skills evident in hemiparesis is the tendency to remain in asymmetric posture, with lower distribution of weight on the side hemiparetic, which ends up leading to a deficit in balance. This set of changes can cause an asymmetrical type of gait, marked by difference between the lengths of the steps these individuals. Objective: The purpose of this study was to analyze the balance, the discharge of weight in the lower limbs and asymmetry of steps in hemiparetic individuals and sees if there is correlation between those variables. Method: A group of 12 hemiparetic individuals (55,33 ± 8,92 years), both sex, who suffered from strokes participated. All subjects performed the assessment of bilateral discharge of weight, the length of the steps and balance (Berg Balance Scale). The results for the difference in the discharge of weight of the lower limbs, asymmetry of the step and the performance on the test of balance were analyzed using the Sperman Correlation Coefficient with a significance level of 5% (p ≤ 0.05). Results: We found a significant correlation between balance and asymmetry of the steps (R = -0.72 and p = 0007), however, found no significant correlation between discharge of weight on each leg and the symmetry of the steps (R =- 0.07 and p = 0, 81) and between discharge of weight and balance (R =- 0.08 and p = 0.79) in these hemiparetic individuals. Conclusion: Can be conclude that hemiparetic individuals of these study show deficits in balance, difference in weight between the discharge of the lower limbs and asymmetry of step and correlation between the asymmetry of the step and balance.

Dinâmica de rotação de exoplanetas tipo terrestre com perturbação de terceiro corpo

In this work we study some topics of Celestial Mechanics, namely the problem of rigid body rotation and “spin-orbit” resonances. Emphasis is placed on the problem formulation and applications to some exoplanets with physical parameters (e.g. mass and radius) compatible with a terrestrial type constitution (e.g. rock) belonging to multiple planetary systems. The approach is both analytical and numerical. The analytical part consists of: i) the deduction of the equation of motion for the rotation problem of a spherical body with no symmetry, disturbed by a central body; ii) modeling the same problem by including a third-body in the planet-star system; iii) formulation of the concept of “spin-orbit” resonance in which the orbital period of the planet is an integer multiple of the rotation’s period. Topics of dynamical systems (e.g. equilibrium points, chaos, surface sections, etc.) will be included at this stage. In the numerical part simulations are performed with numerical models developed in the previous analytical section. As a first step we consider the orbit of the planet not perturbed by a third-body in the star-planet system. In this case the eccentricity and orbital semi-major axis of the planet are constants. Here the technique of surface sections, widely used in dynamical systems are applied. Next, we consider the action of a third body, developing a more realistic model for planetary rotation. The results in both cases are compared. Since the technique of disturbed surface sections is no longer applicable, we quantitatively evaluate the evolution of the characteristic angles of rotation (e.g. physical libration) by studying the evolution of individual orbits in the dynamically important regions of phase space, the latter obtained in the undisturbed case

Teorias de Spin-1: decomposição em helicidades, redução dimensional e imersão de calibre

We have studied the physical content of the following models: Maxwell, Proca, Self-Dual and Maxwell-Chern-Simons. One method we have used is the decomposition in the so called helicity variables, which can be done in the Lagrangian formalism. It leads to the correct counting of degrees of freedom without choosing a gauge condition. The method separates the propagating modes from the non-propagating ones. The Hamiltonian of the MCS and the AD is calculated. The second method used here is the analysis of the sign of the imaginary part of the residues of the two-point amplitude of the theory, showing that the models analyzed are free of ghosts. We also carry the dimensional reduction of the Maxwell-Chern-Simons and Self-Dual models from D = 2+1 to D = 1 + 1 dimensions. Next, we show that the dimensional reduction of those equivalent models also leads to equivalent models in D=1+1. Even more interesting is the fact, demonstrated here, that those reduced models can also be connected via gauge embedding. So the gauge embedding of the Self-Dual model into the Maxwell-Chern-Simons theory is preserved by the dimensional reduction
