目的本研究的目的是对3至12个月婴儿的上肢功能进行描述性和评价性评估，并研究其内部量表对于单侧脑瘫风险婴儿的有效性。方法制定了测试项目的概念和评分标准。基于对 3 至 12 个月校正年龄（平均 7.2 个月，SD 2.5）且具有不对称手部使用迹象的婴儿的 156 项评估，研究了内部量表有效性和可靠性方面。采用Rasch测量模型分析和非参数统计。结果新的婴儿手部评估(HAI)测试由12个单手项目和5个双手项目组成，每个项目均按3分制评分。它展示了一维结构并且非常适合 Rasch 模型的要求。出色的人员可靠性使人员能够分为六个重要的能力层。 HAI 产生了双侧手部使用的区间水平测量以及每只手的单手评分，从而可以量化可能的不对称性，以不对称指数的形式表示。 解释 HAI 可以被认为是测量双侧手部使用情况和量化有单侧脑瘫风险的婴儿手部侧向差异的有效评估工具。
AIM The aim of this study was to develop a descriptive and evaluative assessment of upper limb function for infants aged 3 to 12 months and to investigate its internal scale validity for use with infants at risk of unilateral cerebral palsy.METHOD The concepts of the test items and scoring criteria were developed. Internal scale validity and aspects of reliability were investigated on the basis of 156 assessments of infants at 3 to 12 months corrected age (mean 7.2mo, SD 2.5) with signs of asymmetric hand use. Rasch measurement model analysis and non-parametric statistics were used.RESULTS The new test, the Hand Assessment for Infants (HAI), consists of 12 unimanual and five bimanual items, each scored on a 3-point rating scale. It demonstrated a unidimensional construct and good fit to the Rasch model requirements. The excellent person reliability enabled person separation to six significant ability strata. The HAI produced an interval-level measure of bilateral hand use as well as unimanual scores of each hand, allowing a quantification of possible asymmetry expressed as an asymmetry index.INTERPRETATION The HAI can be considered a valid assessment tool for measuring bilateral hand use and quantifying side difference between hands among infants at risk of developing unilateral cerebral palsy.
