Electromyographic activity in digastric muscles and opening force of mandible during static and dynamic conditions.
A method is presented for simultaneous recording of the integrated electrical activity in the anterior belly of the digastric muscle and the force developed at the chin during static and dynamic conditions of opening. A linear relationship was demonstrated between force and integrated electrical activity during isometric contraction.
