Postural control in strabismic children: importance of proprioceptive information

Front Physiol. 2014 Apr 23:5:156. doi: 10.3389/fphys.2014.00156. eCollection 2014.

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.
