The study was designed to compare active motor items at term age of infants born very preterm, very low birth weight (VPT-VLBW) and without impairments with infants born full-term (FT) and healthy and to evaluate a method of assessment using video recordings and computer software.
Video recordings of head lag and head righting on pull to sit, head control in sitting, and hip flexion in prone were obtained at term age for 29 infants born VPT-VLBW and 22 infants born FT. Motor items were analyzed using digitizing computer software.
Infants born VPT-VLBW had less head lag on pull to sit than infants born FT, p = 0.005. No other differences were found for the remaining motor items. The method of assessment demonstrated high intrarater reliability (intraclass coefficient correlation (3,1) = 0.77-0.997).
Infants born VPT-VLBW who are at "low risk" performed at term age similarly to healthy infants born FT on four active motor items. The reliability of the measurement method supports the method's further development.
本研究旨在比较极早产、极低出生体重（VPT-VLBW）且无损伤的足月婴儿与足月出生（FT）且健康的婴儿在主动运动项目上的表现，并评估一种使用视频记录和计算机软件的评估方法。
对29名VPT-VLBW出生的婴儿和22名FT出生的婴儿在足月时进行了拉起坐起时的头后仰和头转正、坐位时的头部控制以及俯卧位时的髋关节屈曲的视频记录。使用数字化计算机软件对运动项目进行分析。
VPT-VLBW出生的婴儿在拉起坐起时的头后仰比FT出生的婴儿少，p = 0.005。其余运动项目未发现其他差异。评估方法显示出较高的评分者内信度（组内相关系数（3,1）= 0.77 - 0.997）。
“低风险”的VPT-VLBW出生的婴儿在足月时在四项主动运动项目上的表现与FT出生的健康婴儿相似。测量方法的可靠性支持该方法的进一步发展。
