Resumen
El Control Postural Bípedo (CPB) se define como la mantención adecuada de la
orientación del cuerpo en el espacio a pesar de la intervención de la fuerza de
gravedad y las demás fuerzas externas que actúan de forma dinámica sobre él.
La información sensorial que sustenta al CPB proviene de tres sistemas
sensoriales diferentes, el Sistema Visual, el Sistema Somatosensorial y el
Sistema Vestibulococlear; los cuales reciben la información proveniente del
entorno.
El objetivo del presente seminario fue analizar el CPB en 30 estudiantes
universitarias sanas bajo diferentes condiciones de estimulación sensorial,
medido a través de posturografía. Para el desarrollo del seminario, se evaluó
seis condiciones de estimulación sensorial, las cuales permitieron generar
situaciones de facilitación, inhibición y conflicto sensorial.
Los resultados muestran que ante la condición de facilitación no existen
diferencias estadísticamente significativas en el CPB respecto de la condición
basal; situación contraria a lo encontrado en la condición de inhibición sensorial,
en donde si existen diferencias estidísticamente significativas en el CPB. En
tanto, las condiciones de conflicto sensorial muestran que los sujetos son
capaces de mantener un adecuado CPB aún con la inhibición de uno o más
sistemas sensoriales, lo cual demuestra la alta capacidad de los sistemas
sensoriales para suplir a otros y la capacidad de integración que posee el
Sistema Nervioso Central (SNC).
Esto plantea el desafío de crear métodos de intervención y rehabilitación en
pacientes que presenten déficit sensorial, en base a la aplicación de diferentes
tipos de estimulación sensorial.
The Biped Postural Control (BPC) is defined as the proper maintenance of body orientation in space , despite the intervention of the forces of gravity and other externa! forces acting on it dynamically. Sensory information that sustains the BPC comes from three different sensory system, the Visual System, the Somatosensory System and the Vestibulocochlear System, wich recieve information from the enviroment. The objective of this seminary was to analyze the BPC in 30 healthy university students under different conditions of sensory stimulation, as measured by postugraphy. For the development of the seminary, was evaluated six conditions of sensory stimulation, wich allowed to create situations of facilitation, inhibition and sensory conflict. The results show that sensory facilitation do not have statiscally significant differences in the BPC regard the basal condition, a situation that differs befare sensory inhibition, where exist statiscally significant differences in the BPC. Meanwhile, the sensory conflict situations show that subjects are able to maintain an adequate BCP even with the inhibition of one or more sensory systems, wich demonstrate the high capabilities of the sensory systems for supplying each other and the integration capabilities possessed by the Central Nervous System (CNS). This raises the challenge to develop methods of intervention and rehabilitation in patients with sensory deficit, based on the application of different types of sensory stimulation.
