Resumen
La estabilometría comprende una serie de exámenes, mediante los cuales se conoce la ubicación o proyección del centro de gravedad de un paciente en posición de bipedestación. Es una técnica ampliamente usada por muchos profesionales en el área de la salud, ya que sirve para diagnosticar patologías del sistema osteo-muscular y para establecer rutinas de rehabilitación acordes con cada paciente. En este proyecto, se presenta el diseño de una plataforma con cuatro sensores y una estructura metálica en acero SAE 1010, diseñada para soportar grandes esfuerzos y deformaciones. La adquisición y el acondicionamiento de las señales, comienza con una etapa de amplificación y filtrado. Posteriormente, utilizando una tarjeta de adquisición de datos, estas señales se llevan a una interfaz gráfica en LabView, donde se les hace un acondicionamiento digital y se realizan cálculos importantes, como el test de Romberg. Se obtuvieron resultados satisfactorios tanto en el diseño, la modelación y la construcción del dispositivo, así como en las pruebas de estabilometría realizadas.
Abstract— Stabilometry is a field that comprises a series of studies, from which the specialist can study the location and trajectory of the center of gravity of a patient in standing position. It is a widely used technique among health industry professionals. It is also used to diagnose musculoskeletal system diseases and to establish personalized training and rehabilitation sessions for each patient. This project, presents the design of a stabilometric platform with four sensors and a metal structure in SAE 1010 steel, designed to withstand large deformations and efforts. The acquisition and conditioning of the signals begins with an amplification and filtering stage. Then, using a data acquisition device, the data is uploaded to a graphic interface in LabView in order to calculate important variables and factors, such as the Romberg’s coeffi cient. Satisfactory results were obtained both in the design, modeling and construction of the device, as well as in the performed stabilometry tests.
