The peak amplitude of EMG activity was measured from the orbicularis oris superior (OOS), orbicularis oris inferior (OOI), and masseter muscles of a cleft-palate child and compared to data obtained from a normal child. Both children evidenced similar levels of average peak EMG activity and variability of performance across the three muscles. These data were interpreted to suggest that limitations in the function of the OOS, OOI, and masseter muscles do not contribute to the articulatory anomalies exhibited by the cleft-palate child.
测量了一名腭裂儿童口轮匝肌上部(OOS)、口轮匝肌下部(OOI)和咬肌的肌电图活动峰值幅度,并与一名正常儿童的数据进行了比较。两个儿童在这三块肌肉上均表现出相似水平的平均肌电图活动峰值和表现变异性。这些数据被解释为表明口轮匝肌上部、口轮匝肌下部和咬肌的功能限制不会导致腭裂儿童出现发音异常。
