[The prone position as an indicator of deviated motor development during the first year of life]. / La posición prona como indicador de un desarrollo motor desviado en el primer año de la vida.

The adequate control and alignment of a baby in the prone position during the first year of life is a basic necessary milestone for a normal, neuromotor development. In this study the prone position was registered in 246 babies with a previous pediatric evaluation, three options could be made: normal retarded or altered. The Milani Comparetti neuromotor evaluation was also realized for each baby at the same time with the same classification options. Both results were compared. A sensitivity and specificity = 1.0 were found for the prone position registered. This test is fast and simple, so it is recommended at a first attention level in high risk population for neuromotor disability.
