Abstract: Objective To analyze the characteristics of motor development in preterm infants by using the test of infant motor performance (TIMP),and to compare the results of term infants of the same gestational age,so as to provide a reference for the clinical application of TIMP. Methods A total of 617 infants who visited the premature infant clinic and child health care clinic of the Second Affiliated Hospital of Army Medical University were enrolled in this study from July 2018 to June 2019.The general data and TIMP test result were collected and were compared retrospectively according to the different corrected age groups [40~41⁺⁶weeks (62 cases),44~45⁺⁶ weeks (285 cases),48~49⁺⁶ weeks (155 cases),and 52~53⁺⁶ weeks (115 cases)]. Results With the increase of weekly age,the total TIMP score of premature infants increased from 49.46±7.91 in the corrected age of 40~41⁺⁶weeks to 78.09±12.09 in the corrected age of 52~53⁺⁶ weeks,showing a gradually increasing trend (F=67.853,P＜0.001).The scores of observation items and elicited items also showed a gradually increasing trend,and the difference was statistically significant(F=12.811,65.360,P＜0.001).The elicited scores and total scores of preterm infants at the corrected age of 48~49 ⁺⁶ weeks and 52~53⁺⁶ weeks were significantly higher than those of term infants in the same group(t=2.487,2.238,1.906,2.008,P＜0.05). Conclusion s The Chinese version of TIMP can reflect the change of motor capacity of preterm infants in different age groups,and is suitable for motor assessment.Since there is significant difference on motor development between preterm infants and term infants,it is necessary to consider this particularity and select appropriate assessment tools and methods when assessing preterm infants' motor performance and the formulation of early intervention programs.

摘要： 目的 应用婴儿运动表现测试(TIMP)分析早产儿运动发育特点,并与同胎龄足月儿进行比较,为TIMP的临床应用提供参考。方法 收集2018年7月-2019年6月在陆军军医大学第二附属医院早产儿门诊和儿童保健门诊就诊的617名婴儿的一般资料和TIMP测试结果,按照矫正年龄分为40~41⁺⁶周(62例)、44~45⁺⁶周(285例)、48~49⁺⁶周(155例)及52~53⁺⁶周(115例)4组,进行回顾性分析比较。结果 随着周龄增大,早产儿TIMP总分从矫正胎龄40~41⁺⁶组的49.46±7.91逐渐增加至矫正胎龄52~53⁺⁶组的78.09±12.09,呈逐渐增加的趋势(F=67.853,P＜0.001);观察项目和诱发项目得分亦呈逐渐增加趋势,差异具有统计学意义(F=12.811,65.360,P＜0.001)。矫正年龄48~49⁺⁶周、52~53⁺⁶周组早产儿诱发项目得分和总分较同组足月儿高,差异具有统计学意义(t=2.487,2.238,1.906,2.008,P＜0.05)。结论 中文版TIMP能够反映不同周龄组早产儿运动能力变化,适用于早产儿运动评估。早产儿运动发育与足月儿存在差异,所以在对早产儿运动能力评价和早期干预方案的制定上需要考虑到这种特殊性并选用合适的评估工具及方法。
