ABSTRACT
A principal block scheme of an apparatus complex is suggested and a method for examination of masticatory muscle function is described. The method is based on electrostimulation of masticatory nerve followed by registration and analysis of the masticatory muscle action evoked potentials. The block scheme of the apparatus complex includes a universal electrostimulator ESU-2. Examinations of 30 healthy volunteers and 30 patients with unilateral fractures of the mandible helped define the major parameters of stimulation electromyography. The patients were treated by splints applied on the teeth with fixation on both jaws. By day 28 of the investigation the M-response amplitude dropped more than twofold and its length by 1.5 times as against the mean parameters in health.
