Resumen
El comportamiento del centro de presión (CoP) es un factor el cual posee importantes características a la hora de establecer patrones de movimiento, diagnóstico y tratamiento relacionados a la postura y a la estabilidad tanto estática como dinámica. El objetivo del estudio es describir el comportamiento del centro de presión en sujetos sanos con un estudio posturográfico analizado mediante el modelo ARFIMA de series de tiempo. Se evaluaron 33 sujetos los cuales fueron sometidos a pruebas antropométricas y a una prueba de 90 segundos con ojos abiertos, donde debían mantener la postura más cómoda que ellos determinaran sobre el oscilografo postural. Para esto se les detalló el proceso a través de un consentimiento informado y se estimó mediante criterios de inclusión y exclusión si era posible su participación. Los resultados demostraron una mayor variabilidad por parte de las adaptaciones de los participantes en el eje antero posterior, esto en relación a la orientación de sus estructuras corporales y a que los estímulos o perturbaciones están mayormente orientadas en dicho eje. Con respecto al análisis bajo el modelo ARFIMA se concluye que el proceso dinámico de los cambios en el comportamiento al centro de presión, posee características que lo hacen analizable bajo condiciones como gran dependencia de los datos a información previa, esto sería relevante para futuras investigaciones cuyos objetivos sean determinar patrones en pacientes patológicos en fin de la creación de métodos de diagnóstico y tratamiento en base a los márgenes en que se mueve el comportamiento del centro de presión.
The behavior of the center of pressure (CoP) is a factor which has important features in establishing patterns of movement, diagnosis and treatment related to posture and both static and dynamic stability. The aim of the study is to describe the behavior of the center of pressure in healthy subjects with a posturographic study analyzed by the ARFIMA time series model. 33 subjects who underwent anthropometric tests and a test of 90 seconds with open eyes, which were the most comfortable position to maintain them determine on postural oscillograph were evaluated. To this they are explained the process through informed consent and was estimated by inclusion and exclusion criteria if possible their participation. The results showed greater variability by adaptations of the participants in the anteroposterior axis, this in relation to the orientation of their body structures as stimulus or disturbances are mostly focused on that axis. With respect to the analysis under the ARIMA model concludes that the dynamic process of changes in the behavior center of pressure, has features that make it analyzable under conditions such as heavy reliance on data to previous information, this would be relevant for future research whose objectives are to determine pathological patterns in patients in order to create methods of diagnosis and treatment based on margins in the behavior of the center of pressure moves.
