Abstract
Objective: To examine the effect of proprioceptive information during postural control in strabismic children.Methods: Postural stability was recorded with a platform (Techno Concept®) in 12 strabismic children aged from 4.9 to 10 years and data were compared to that of 12 control age-matched children. Two postural positions were performed: Romberg and Tandem. Two postural conditions: without and with foam pad. We analyzed the surface area, the length, the mean speed of the center of pressure (CoP) and the effect of proprioceptive information.Results: Strabismic children are more instable than control age-matched children. The surface, the length and the mean speed of CoP are significantly higher in strabismic children than in control age-matched children. Both groups are more instable in Tandem position than in Romberg position. Finally, strabismic children use more proprioceptive information than control age-matched children.Conclusion: For both Romberg and Tandem position, strabismic children are more instable than control age-matched children. Strabismic children use proprioceptive information more than control age-matched children to control their posture.Significance: Proprioceptive inputs are important for control posture particularly for strabismic population.

Summary
The postural system allows the effective spatial coordination of body segments with each other during daily activities. 2% of children under 7 years old suffer from strabismus (Williams et al, 2008). In many cases, it is responsible for abnormal alignment of the eyes and abnormal binocular vision. Given the well-known importance of visual information for postural control in younger children (Shumway-Cook and Woollacott, 1985), we further explored how deficits of vision as is the case for strabismus could interfere with postural control. For this reason we studied strabismic children.
