As funções do controle postural durante a postura ereta

Abstract

The postural control is the control of the body segments based in information of the visual, vestibular and somatossensorial. There are evidences that the level of importance of the sensorial information is tunable and redundant. The anatomical separation of the sensorial systems and the significant degradation of the sensorial information, when we close the eyes or when we stand on moving, unstable or soft support suggest that the nervous system has the ability to discretely change the principal source of sensorial information. The set of sensorial information creates a picture of references. The frame of reference controls the parameters of the postural control in relation to the gravitational field. The
postural control is based on the monitoring the internal representation of posture, the body image, which is a geometric and kinetic representation of the human body, how the forces and gravity are applied to the body. The functions of the postural control are support, stability and balance. The aim of this paper was to discuss the relation between biomechanical and motor control aspects and sensorial systems for the control of standing posture.
