Infants with very low birth weight (VLBW) are at increased risk for motor deficits, which may be reduced by early intervention programs. For detection of motor deficits and to monitor intervention, different assessment tools are available. It is important to choose tools that are sensitive to evaluate the efficacy of intervention on motor outcome.
The purpose of this study was to compare the Alberta Infant Motor Scale (AIMS) and the Psychomotor Developmental Index (PDI) of the Bayley Scales of Infant Development-Dutch Second Edition (BSID-II-NL) in their ability to evaluate effects of an early intervention, provided by pediatric physical therapists, on motor development in infants with VLBW at 12 months corrected age (CA).
This was a secondary study in which data collected from a randomized controlled trial (RCT) were used.
At 12 months CA, 116 of 176 infants with VLBW participating in an RCT on the effect of the Infant Behavioral Assessment and Intervention Program were assessed with both the AIMS and the PDI. Intervention effects on the AIMS and PDI were compared.
Corrected for baseline differences, significant intervention effects were found for AIMS and PDI scores. The highest effect size was for the AIMS subscale sit. A significant reduction of abnormal motor development in the intervention group was found only with the AIMS.
No Dutch norms are available for the AIMS.
The responsiveness of the AIMS to detect intervention effects was better than that of the PDI. Therefore, caution is recommended in monitoring infants with VLBW only with the PDI, and the use of both the AIMS and the Bayley Scales of Infant Development is advised when evaluating intervention effects on motor development at 12 months CA.
极低出生体重儿（VLBW）患运动障碍的风险增加，而早期干预计划可能会降低这种风险。为了检测运动障碍并监测干预效果，有不同的评估工具可供使用。选择能够敏感评估干预对运动结果疗效的工具非常重要。
本研究旨在比较 Alberta 婴儿运动量表（AIMS）和 Bayley 婴儿发育量表第二版（BSID-II-NL）的精神运动发育指数（PDI），以评估儿科物理治疗师提供的早期干预对 12 个月校正年龄（CA）时 VLBW 婴儿运动发育的影响。
这是一项二次研究，使用了随机对照试验（RCT）中收集的数据。
在 12 个月 CA 时，对参加婴儿行为评估和干预计划 RCT 的 176 名 VLBW 婴儿中的 116 名进行了 AIMS 和 PDI 评估。比较了干预对 AIMS 和 PDI 的影响。
校正基线差异后，AIMS 和 PDI 评分均显示出显著的干预效果。AIMS 坐位亚量表的效果量最大。仅在 AIMS 中发现干预组异常运动发育的显著减少。
AIMS 无荷兰正常值。
AIMS 对检测干预效果的反应性优于 PDI。因此，仅用 PDI 监测 VLBW 婴儿时需谨慎，并建议在评估 12 个月 CA 时运动发育的干预效果时同时使用 AIMS 和 Bayley 婴儿发育量表。
