Abstract: Objective To study the clinical application of the general movement assessment technology in motor developmental retardation. Methods A total of 93 infants included in Rehabilitation Department of Children's Hospital of Changzhou from January 1st of 2016 to June 31st of 2017 were assessed by general movement assessment technology and were followed to the age of 6 months. The motor development outcomes of the infants at the age of 6 months were determined according to PDMS-2. The predictive validity of the general movement for the motor developmental outcome was calculated. Results Totally 93 infants' motor developmental outcomes were assessed at 6 months using PDMS-2. Eight infants were assessed with motor developmental retardation, and the other 85 infants' results were normal. The predictive value of abnormal writhing general movements(CS+PR) for motor developmental retardation was as following: sensitivity validity 100%, specificity validity 58.7%, positive predictive value 20.8%, and negative predictive value 100%. The predictive value of cramped-synchronized general movements for motor developmental retardation was as following: sensitivity validity 60.0%, specificity validity 93.5%, positive predictive value 50.0%, and negative predictive value 95.6%.The predictive value of absence of fidgety movements for motor developmental retardation was as following: sensitivity validity 100%, specificity validity 84.3%, positive predictive value 38.9%, and negative predictive value 100%. Conclusion The general movement assessment technology can be used as an effective tool for screening motor developmental retardation infants.
