Robust Control of the Classic Dynamic Ball and Beam System

Abstract: This article presents the design of robust control system for the Ball and Beam system, as well as the comparison of their performances with classic control techniques. Two controllers were designed based on Algebraic Riccati Equations for the synthesis of H2 and H∞ controllers and a third one based on Linear Matrix Inequalities techniques for the design of H∞ controllers. The results show that H∞ controllers offer better performance.

Acción de los fisioterapeutas en situaciones de desacondicionamiento en unidades de cuidado intensivo

Abstract: Physical deconditioning is a physiological and metabolic loss of conditions that affects various systems due to the permanence of a person at rest. It affects their performance and functional possibilities and it is commonly found in intensive care units (ICU). In this context, this situation could be intervened with programs of physiotherapy action. Objective: to review the in recent literature the guidance elements for interventions made by Physiotherapists in situations of deconditioning in intensive care units. Method: A document review research was made, with a descriptive range, by consulting databases between June 2014 and February 2015. Results: In the research, 32 articles that met the inclusion criteria were found and 53% of them were experimental studies. Intervention approaches focused on strategies aimed at training aerobic capacity, muscular strength and endurance, 25% of these articles showed that patients who were involved of Physical Therapy in intensive care units had a significant improvement in lung function, muscle performance and particularly in the effective training of the explosive force. Conclusions: The research showed that early interventions made by professionals in Physiotherapy can reverse the complications caused by prolonged immobility and these should be implemented during the first 24 hours after the admission of the patient.

Poder en la política de salud colombiana: la sociedad civil y la reforma a la salud de 2013

Abstract: Este estudio busca identificar las relaciones de poder entre sociedad civil y Estado en el debate presentado en Colombia durante la reforma a la salud realizada en 2013. Se discuten los hallazgos en funcion de los conceptos y argumentos acerca del poder postulados por el filosofo Michel Foucault. Los resultados senalan que la configuracion del Sistema General de Seguridad Social en Salud conllevo anos despues la determinacion de multiples actores dentro del sistema, con disparidad de poderes de accion frente al desarrollo de la politica publica de salud. Los grados de participacion y de poder se asocian a la naturaleza social del estamento al que pertenece cada grupo y a los intereses economicos o politicos que representan. Se recomiendan acciones centradas hacia la construccion social de una politica de salud enfocada en la garantia de esta desde una perspectiva de derecho que module los alcances mercantiles y economicos asociados a la politica que regulan y determinan (entre otras) el sistema de salud en Colombia.

Postural Control Assessment in Multiple Sclerosis by Diffusion Analysis on Kinect Skeleton Data

Abstract: Multiple Sclerosis (MS) is a central nervous system disease widely known for being a non-reversible degeneration process that affects young adults as well as elder people. Such disease affects the equilibrium function of the postural control system required to perform vital tasks such as walking or hold upright position. To palliate the long-term effects associated to MS, physicians perform therapeutic interventions on patients in order to preserve their motor capabilities as best as possible. In order to evaluate the effectiveness of therapeutic interventions, representative measurements or scores are used to assess the actual state of each patient. This work presents an exploratory approach to provide quantitative mediolateral and anteroposterior balance descriptors in MS through Diffusion Analysis on balance data acquired with a low-cost computational system using a Kinect device. The obtained results were compared against a subset of exercises of the Berg Balance Scale.
