inclusion difficulties

Prematurity is a major risk factor for poor neurodevelopmental outcomes. The clinical and neuroradiological evaluations proposed during the neonatal period to assess the developmental prognosis of children born prematurely are not sensitive and nor specific. The analysis of spontaneous motor activity by Prechtl's method has a better predictive value but is currently unfeasible in clinical routine. The study's principal objective is to describe the standardized values of complexity, variability, and fluidity of general movements.
