Objective: To investigate the differences between the Test of Infant Motor Performance (TIMP) data from the infants at 38-58 weeks of postconceptual age in three hospitals in Chongqing, China and the America norms, and to provide a reference for the introduction and application of TIMP in China.
Methods: TIMP was used to assess 642 infants with 38-58 weeks of postconceptual age who visited the departments of preterm infants or child healthcare in the Second Affiliated Hospital of Army Medical University, Shapingba Maternal and Child Health Hospital in Chongqing, and Chongqing Maternal and Child Health Hospital between January and December, 2016. The assessment scores were analyzed and compared with the America norms.
Results: The TIMP scores increased with the increasing postconceptual age, with 37±5 points in the 38-39+6 week group and 83±12 points in the 56-57+6 week group. All age groups had a significantly lower mean score than the America norms (P<0.001).
Conclusions: TIMP scores can reflect the motor performance in infants with various postconceptual ages. The TIMP scores from the infants with a postconceptual age of 38-58 weeks in three hospitals in Chongqing are significantly different from the America norms, suggesting that it is very necessary in China to establish the Chinese norms for assessing motor performance in infants using TIMP.
目的: 探讨基于重庆3所医院矫正胎龄38~58周婴儿的运动表现测试（TIMP）数据与美国常模数据的差异，为TIMP在国内的引进及应用提供参考。
方法: 使用TIMP对2016年1~12月在陆军军医大学第二附属医院、重庆市沙坪坝区妇幼保健院、重庆市妇幼保健院早产儿随访门诊或儿保门诊就诊的642例矫正胎龄38~58周婴儿进行评估测试，统计评估得分并与美国常模数据进行比较。
结果: 该组婴儿TIMP得分随婴儿矫正胎龄的增加而升高，从38~39+6周龄组的37±5分，增加至56~57+6周龄组的83±12分。但各周龄组平均得分均低于美国常模，差异有统计学意义（P < 0.001）。
结论: TIMP评估得分可反映不同矫正胎龄婴儿的运动能力。基于重庆3所医院门诊矫正胎龄38~58周婴儿的TIMP数据与美国常模相比差异较大，提示在国内使用TIMP评估小婴儿运动能力前建立中国TIMP常模非常必要。
