Avaliação do equilíbrio estático em indivíduos com estrabismo

Abstract

The postural balance in individuals with visual impairment, such as strabismus, has been the subject of several studies, since vision plays an important role in maintenance of posture and equilibrium, being the main source of input information for maintaining static equilibrium. Objective: To evaluate static balance in subjects with strabismus. Methodology: Descriptive and qualitative cross-sectional study comprised 14 volunteers, divided into two groups - Group study, 07 cross-eyed individuals, and control group, 07 sighted individuals - and evaluated the static balance by stabilometry platform, first with eyes open, and then closed, the still standing position for 52 seconds each time. Results: It was found that the average speed of oscillation in mm/s (p=0,0327) and the displacement latero-lateral (L/L) in mm/s (p=0,0014) the eyes open condition showed statistically significant differences between groups, as well as the displacement antero-posterior (A/P) in mm/s (p=0,0244) with eyes closed. Conclusion: There are significant changes in the maintenance of static balance in strabismic individuals in the L/L offset and average speed of oscillation, when with open eyes, however there is a positive correlation with respect to the displacement A/P in the eyes closed condition when compared with subjects with normal vision.
