The project presented here aims to evaluate the discrimination capacity of the Observation of Sensory-Motor Behavior (OSMB) grid of the preterm infant, as well as its predictive capacity for the child's later psychomotor development.

To do this, OSMB grids will be completed during dystimulant care and during stabilizing care in 65 preterm infants. In addition, an OSMB grid will also be completed during a sensorimotor assessment at 37 weeks gestational age and at 1 month corrected for prematurity in 100 preterm infants. The OCSM scores will then be compared to the Bayley III scale scores at 6 months of age corrected for prematurity.
