Electrophysiological studies of a patient with cephalic tetanus, manifested by trismus and unilateral facial palsy, revealed that the trismus resulted from strictly unilateral masseter spasm which stopped during sleep, a normal silent period in the involved masseter muscles, initially prolonged distal latency of the paretic orbicularis muscles, and abnormal continuous muscle activity in the par...

Therefore, this study aimed to investigate jaw opening（e.g. during dental treatment）on fatigue, pressure pain sensations, stiffness muscles. A total 35 healthy volunteers performed 30 minutes each two motor tasks, with a 1-w...
