Abstract__ Background By quantifying the information entropy of postural sway data the complexity of the postural movement of different populations can be assessed giving insight into pathologic motor control functioning. Methods In this study developmental delay of motor control function in infants was assessed by analysis of sitting postural sway data acquired from force plate center of pressure measurements. Two types of entropy measures were used .
