Repeatability of frequency of corrective foot pressure during balance control in children aged between 2 and 7.

摘要: The frequency of corrective signal (the centre (COC) signal), which is the decomposition COP (centre pressure) and estimated COM mass) time series, one indicators reflecting quality postural control during stance. Young children, in period intensive development, gradually improve a daily life. purpose this paper was to describe series foot pressure repeatability young children aged between 2 7 body stability natural stance position. 272 healthy were divided into 6 age groups. Two AccuSway force platforms used (one subject on platform, second foot, other). trajectories basis for calculation indices frontal sagittal planes left leg right separately. COC signals collected by method based Kuczynski viscoelastic model. In order assess repeatability, concordance correlation coefficient (CCC) 1st 2nd trials, 3rd trials. maturation system goes rather slowly two youngest groups showed poor years From 4th 7th year life inter-session rapidly increases three consecutive Poor difference found lower limbs. It concluded that reliable indicator 4 7, but not younger ones.
