Electromyograms were recorded with hooked-wire electrodes from sixteen lip, tongue and jaw muscles in six normal and seven cerebral palsied adult subjects during a variety of speech and non-speech tasks. The recorded patterns of muscle activity fail to support a number of theories concerning the pathophysiology of dysarthria in cerebral palsy. There was no indication of weakness in individual articulator muscles. There was no evidence of uncontrolled sustained background activity or of abnormal tonic stretch reflex responses in lip or tongue muscles. Primitive or pathological reflexes could not be elicited by orofacial stimulation. No imbalance between positive and negative oral responses was observed. The view that random involuntary movement disrupts essentially normal voluntary control in athetosis was not supported. Each cerebral palsied subject displayed an idiosyncratic pattern of abnormal muscle activity which was reproduced across repetitions of the same phrase, indicating a consistent defect in motor programming.
在六个正常成年人和七个成年脑瘫患者进行各种言语和非言语任务期间，用钩丝电极记录了十六块唇、舌和颌部肌肉的肌电图。记录的肌肉活动模式未能支持一些关于脑瘫构音障碍病理生理学的理论。没有迹象表明单个发音肌肉存在无力。没有证据表明唇或舌部肌肉存在不受控制的持续背景活动或异常的强直性牵张反射反应。口面部刺激无法引出原始或病理性反射。未观察到阳性和阴性口腔反应之间的不平衡。手足徐动症中随机的不自主运动扰乱基本正常的自主控制这一观点未得到支持。每个脑瘫患者都表现出一种独特的异常肌肉活动模式，在重复相同短语时会再现，这表明运动编程存在持续缺陷。
