Predictive value of definitely abnormal general movements in the general population.

Aim: Definitely abnormal general movements in populations of high-risk infants predict serious neurodevelopmental impairment. This study aimed to assess predictive values of definitely abnormal general movements at 3 months for serious neurodevelopmental impairment in a representative sample of the general population.

Method: A prospective cohort study of 455 3-month-old infants was performed (241 females, 214 males; mean birthweight 3452g, SD 604g; mean gestational age 39.

Prevalence of abnormal general movements in three-month-old infants.

Background: The quality of general movements (GMs) is a sensitive tool to measure neurodevelopmental condition in early infancy. No information is available on prevalence rates of abnormal GMs in the general population.

Objective: To assess the prevalence of abnormal GMs in the general population of three-month-old infants and to evaluate the association of abnormal GM quality with medical and social risk factors.
