Abstract Background The present study investigates balance control mechanisms their variations with the absence of visual input and their development in children from 7 to 11 years old in order to provide insights on the development of balance control in the pediatric population. Methods Posturographic data were recorded during 60 s trials administered on a sample population of 148 primary school children while stepping and then quietly standing on a force plate in two different vision conditions eyes closed and eyes open. The extraction of posturographic parameters on the quiet standing phase of the experiment was preceded by the implementation of an algorithm to identify the settling time after stepping on the force plate.
