旨在
这项初步研究的目的是评估3D摄像在分析新生儿身体质心（COM）运动中的潜在用途，并确定早产儿和足月儿之间自发运动的差异。
方法
该组包括10名早产儿（出生时胎龄在26至37周之间;出生体重800至2960 g;检查时胎龄为34至39周）和10名足月婴儿（胎龄38至41周;出生体重2810至4360 g）。为了确定COM的运动范围，使用3D摄像（2台摄像机，25 Hz）。当记录他们的动作时，婴儿处于仰卧位，平静而清醒。使用APAS软件处理记录。对身体上的选定点进行标记，以获取计算COM轨迹基本参数的数据。
结果
早产儿COM在前后方向的活动范围均显著大于足月儿（分别为P < 0.05和P < 0.01）。早产儿COM的运动变异性在前后方向（P <0.05）和前后方向（P <0.01）上均显著增大。COM在前后方向的运动速度也有显著性差异（P < 0.05）。
结论
3D录像可用于早产儿运动行为的实验评估。COM运动的基本运动学特征（范围、变异性、速度）在早产儿中更大。
AIMS
The objectives of this pilot study were to assess the potential use of 3D videography for analyzing the motion of the body center of mass (COM) in newborns and to determine differences in spontaneous movements between preterm and full-term infants.
METHODS
The group comprised 10 preterm newborns (gestational age at birth between 26 and 37 weeks; birth weight 800 to 2960 g; gestational age at the time of examination 34 to 39 weeks) and 10 full-term infants (gestational week 38 to 41; birth weight 2810 to 4360 g). To determine the range of motion of the COM, 3D videography was used (2 cameras, 25 Hz). When recording their movements, the infants were in the supine position, calm and awake. The recordings were processed using the APAS software. Selected points on the body were marked to obtain data for calculating the basic parameters of COM trajectories.
RESULTS
The range of motion of the COM in both craniocaudal and anteroposterior directions was significantly greater in premature infants (P < 0.05 and P < 0.01, respectively) than in full-term babies. The variability of motion of the COM was significantly greater in the craniocaudal (P < 0.01) and anteroposterior (P < 0.05) directions in preterm babies. This was also valid for the velocity of motion of the COM in the craniocaudal direction (P < 0.05).
CONCLUSIONS
3D videography can be used for experimental assessment of motor behavior in preterm infants. Basic kinematic characteristics of the motion of the COM (range, variability, velocity) are greater in preterm infants.
