The author studied the changes of muscle activity with Bioelectric processor Model EM2(Myo. tronics Corp., U.S.A.) before and after occlusal stabilization splint therapy. For this study, 15,, temporomandibular disorders patients and 15 students without any temporomandibular disor symptoms were selected, for experimental group and control group, respectively.
Experimental group were treated with occlusal stabilization splint and checked about electro. myographic activity before and after therapy. Electromyographic levels were measured in both.: groups at the following mandibular position, i.e., physiologic rest, tapping, light biting, hard, open without pain, open with pain, right excursion and ipsilateral biting, left excursion and ipsilateral biting, protrusion, protrusive biting, edge biting and physiologic rest after movement..
The obtained results were as follows
2. In general, the pre-treatment mean values of muscle activity in experimental group were than those of control group.
3. In experimental group, no statistically significant difference appeared between affected ate" unaffected side.
4. The mean value of muscle activity in physiologic rest position after each movement check wa lower than that before each movement check.
treatment values.
