GMs评估技术对6月龄婴儿运动发育迟缓的预测研究

目的 研究GMs评估技术在运动发育迟缓方面的临床应用,为临床有效诊治提供参考依据。方法 2016年1月1日—2017年6月31日期间,本院康复科对93例婴儿进行全身运动(GMs)评估,并且随访到6月龄,应用Peabody运动发育量表-2(PDMS-2)评定6月龄婴儿的运动发育能力,以6月龄运动发育是否迟缓作为标准来计算GMs评估对运动发育结局的预测效度。结果 93例随访到了6月龄的婴儿中运动发育迟缓儿8例,其余85例6月龄时的评估结果均正常。扭动阶段异常GMs(CS+PR)对运动发育迟缓的预测效度为:敏感度100%、特异度58.7%;阳性预测值20.8%、阴性预测值100%。扭动阶段异常GMs(CS)对运动发育迟缓的预测效度为:敏感度60%、特异度93.5%;阳性预测值50%、阴性预测值95.6%。不安阶段异常GMs(F-)对运动发育迟缓的预测效度为:敏感度100%、特异度84.3%;阳性预测值38.9%、阴性预测值100%。结论 GMs评估技术可以作为一种高效的工具用于筛查运动发育迟缓的患儿。

Research on the predictive validity of general movement assessment technologyin motor developmental retardation of 6 months infants

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.
