Análise do equilíbrio estático em pessoas com deficiência visual e pessoas hígidas com olhos vendados

Abstract

Postural control is directly dependent on sensory information of the visual, vestibular and somatosensory systems. Changes in sensory, motor and cognitive variables provide a deficit in the ability to maintain the balance. The aim of this study was to compare postural stability between visually impaired and healthy subjects, by means of stabilograph analysis. With this objective, a force platform was used to analyze the COP (center of pressure) displacement of five sightless individuals and five blindfolded individuals. The test was performed with the volunteers in Frankfurt position during one minute, on the force platform. Based on the theoretical reference consulted and on the results obtained, it is concluded that despite the balance deficit generated by the low vision of the individuals of the group of people with visual impairment, they can have greater postural stability in a static equilibrium test, in a situation of Blindfolded when compared to healthy individuals. This is due to the fact that there is neural compensation in order to maintain the proper functioning of the body.
