Physical therapist examination of pediatric clients or clients with neurological conditions often includes the observation of stereotypical movement patterns such as the asymmetrical tonic neck reflex and righting reactions. The purpose of this study was to investigate whether extremity and trunk responses to passive head turning could be documented in newborn infants.
Forty-two newborns with no known medical problems were videotaped within 5 days of birth while an investigator turned their heads left and right. Videotapes were stopped at 5-second intervals to record the direction of head turn with the rest of the body obscured. A second investigator recorded trunk and extremity position with the head obscured.
The direction of head turning affected upper- and lower-extremity position, with extension stronger on the face side. The direction of trunk convexity was also affected by head position, with the trunk convex to the side to which the face was turned.
Extremity responses and trunk responses to passive head turning can be documented corresponding to patterns reported for the asymmetrical tonic neck reflex and righting reflexes in neonates with no known medical problems more frequently than would occur by chance.
物理治疗师对儿科患者或患有神经疾病的患者进行检查时，通常会观察刻板运动模式，如非对称性紧张性颈反射和矫正反应。本研究的目的是调查在新生儿中是否可以记录到被动转头时四肢和躯干的反应。
42名无已知医学问题的新生儿在出生后5天内被录像，一名研究者将他们的头左右转动。录像以5秒的间隔停止，记录转头的方向，身体其他部分被遮挡。另一名研究者在头部被遮挡的情况下记录躯干和四肢的位置。
转头方向影响上肢和下肢的位置，面部一侧的伸展更强。躯干的凸侧方向也受头部位置的影响，躯干向面部转动的一侧凸出。
对于无已知医学问题的新生儿，被动转头时的四肢反应和躯干反应可以按照非对称性紧张性颈反射和矫正反射所报告的模式记录下来，其出现频率高于偶然发生的情况。
