PURPOSE
This preliminary study compared the speech motor control of the tongue and jaw between children with cerebral palsy (CP) and their typically developing (TD) peers.
METHOD
Tongue tip and jaw movements of 4 boys with spastic CP and 4 age- and sex-matched TD peers were recorded using an electromagnetic articulograph during 10 repetitions of "Dad told stories today." The duration, path distance, average speed, and speech movement stability of the movements were calculated for each repetition.
RESULTS
The children with CP had longer durations than their TD peers. Children with CP had longer path distances and faster average speed as compared with their TD peers for both articulators. The TD group but not the CP group had longer path distances and faster average speeds for the tongue than the jaw. The CP group had reduced speech movement stability for the tongue as compared with their TD peers, but both groups had similar speech movement stability for the jaw.
CONCLUSIONS
Children with CP had impaired speech motor control of the tongue and jaw as compared with their TD peers, and these speech motor control deficits were more pronounced in the tongue tip than the jaw.
目的
本初步研究比较了脑瘫（CP）患儿与其发育正常（TD）的同龄人在舌部和下颌的言语运动控制情况。
方法
使用电磁关节描记器记录4名痉挛型脑瘫男孩及其4名年龄和性别匹配的发育正常的同龄人在重复10次“爸爸今天讲故事”时的舌尖和下颌运动。计算每次重复运动的持续时间、路径距离、平均速度和言语运动稳定性。
结果
脑瘫患儿的持续时间比发育正常的同龄人更长。与发育正常的同龄人相比，脑瘫患儿的两个发音器官的路径距离更长，平均速度更快。发育正常组的舌部路径距离比下颌更长，平均速度更快，但脑瘫组并非如此。与发育正常的同龄人相比，脑瘫组的舌部言语运动稳定性降低，但两组下颌的言语运动稳定性相似。
结论
与发育正常的同龄人相比，脑瘫患儿的舌部和下颌言语运动控制受损，且这些言语运动控制缺陷在舌尖比在下颌更明显。
