Mechanomyography (MMG) involves recording and quantifying the low frequency lateral oscillations of active skeletal muscle fibers [1,2]. Although the exact origin(s) of the MMG signal is not completely understood, Gordon and Holbourn [3] suggested that MMG reflects the mechanical counterpart of mot...
[Muscle fiber conduction velocity and frequency parameters of surface EMG during fatigue of the human masseter muscle. 2. Frequency parameters]. During sustained isometric contraction of the jaw muscles, muscular fatigue causes a shift towards lower frequencies in the EMG frequency power spectrum. T....

Kimura, reported on the mechanical work done by the masticatory movement of the human lower jaw. But in daily life, besides the mastication the lower jaw performes various movements, for example talking, drinking, smoking and others. From the physiological viewpoint it is by no means meaningless...
Temporalis muscle was active during centric closing of the jaw with either contact of the teeth, or against resistance; during free lateral movements to the ipsilateral side, either against resistance or occlusal contact; during incisor gum chewing, molar gum chewing on ipsilateral or contralateral ...
