EMG Activity of Orbicularis Oris Superior, Orbicularis Oris Inferior, and Masseter Muscles of Articulatory Disordered Children

Perceptual and Motor Skills, 1984
The peak amplitude of EMG activity was measured from the orbicularis oris superior (OOS), orbicularis oris inferior (OOI) and masseter muscles for 8 normal and 8 articulator disordered children, and 8 normal adults repeating /p æ/ at a fast rate. The three groups of subjects evidenced similar levels of average peak EMG activity across the three muscles;
