Early Motor Repertoire in Infants With Biliary Atresia: A Nationwide Prospective Cohort Study

The aim of the study was to assess the neurological status in infants with biliary atresia (BA) at time of diagnosis, using Prechtl's validated General Movement Assessment. Infants diagnosed with BA were prospectively included in a nationwide cohort study. From birth to approximately 46 weeks of postmenstrual age (PMA), general movements (GMs) are defined as "writhing movements." At 46 to 49 weeks PMA, "'fidgety movements" emerge. The infant's early motor repertoire was recorded on video before Kasai portoenterostomy. We scored GM optimality scores (min-max 5-42) or motor optimality scores (MOS, min-max 5-28) as appropriate. We defined GM optimality scores
