The predictive validity of infant neuromotor evaluation by the Movement Assessment of Infants (MAI) was investigated in low-birthweight infants. Motor performance at four and eight months was examined in relation to neurodevelopmental outcome at 18 months of age. Correlations were equally strong between total MAI risk scores at four and eight months and performance on the Bayley Scales. Muscle tone observations were more discriminating at four months, and automatic reactions and volitional movement were most predictive at eight months. The MAI was highly sensitive to neurodevelopmental abnormality at four and eight months and more sensitive than the Bayley Motor Scale; both assessment tools had lower specificity at eight months. The high false-positive rate is attributed to transient neuromotor abnormalities and immaturity of motor function in low-birthweight infants with normal outcome.
我们对低体重婴儿进行了婴幼儿运动评估（MAI），以研究婴儿神经运动评估的预测效度。我们考察了4个月和8个月时的运动表现与18个月时神经发育结果之间的关系。4个月和8个月时的MAI总风险评分与贝利量表上的表现之间的相关性同样很强。4个月时肌肉张力观察的区分度更高，8个月时自动反应和随意运动的预测性最强。MAI在4个月和8个月时对神经发育异常高度敏感，且比贝利运动量表更敏感；两种评估工具在8个月时的特异性均较低。高假阳性率归因于结局正常的低体重婴儿存在短暂的神经运动异常和运动功能不成熟。
