This was a clinical trials study of self-regulation of rhythmic stimulation in preterm infants. Infants were enrolled in three regional hospitals and followed in four outlying hospitals. Forty-five premature infants, 22 males and 23 females, enrolled at 29-33 weeks conceptional age (CA) received in the isolette either a "breathing" teddy bear (set to breathe at one-half the infant's quiet sleep respiration rate) or a nonbreathing bear. Using time-lapse videorecording at a 60:1 ratio, subjects were recorded for 3 days at the beginning of the Intervention period and again for 3 days, 2 weeks later. After discharge from the hospital, the sleep of the subjects was monitored in the home for a 24-hour period on weeks 1, 2, 3, 4, and 5 after expected date of birth (postterm). Infants with a breathing bear spent more time in contact with the bear, and increased their contact over the two weeks. Postterm, the "breathing bear babies" showed more quiet sleep and a greater increase in quiet sleep over weeks. The results indicate that premature infants ("prematures") are capable of organizing their motility to express a preference for rhythmic stimulation, and that the experience facilitates neurobehavioral development.
这是一项关于早产儿节律性刺激自我调节的临床试验研究。婴儿在三家地区医院登记入组，并在四家偏远医院进行随访。45名早产儿，22名男性和23名女性，孕龄（CA）为29 - 33周，在保温箱中接受了一只“呼吸”泰迪熊（设置为以婴儿安静睡眠呼吸频率的一半进行呼吸）或一只不呼吸的熊。以60:1的比例进行延时录像，在干预期开始时对受试者记录3天，2周后再记录3天。出院后，在预期出生日期（足月后）的第1、2、3、4和5周，对受试者在家中的睡眠进行24小时监测。拥有呼吸熊的婴儿与熊接触的时间更多，并且在两周内接触时间增加。足月后，“呼吸熊宝宝”表现出更多的安静睡眠，并且在几周内安静睡眠增加幅度更大。结果表明，早产儿能够组织自身运动以表达对节律性刺激的偏好，并且这种体验促进神经行为发育。
