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.
