Evaluation of mastjcatory muscle tone by analyzing vertical mandibujar movement with electric stimulationKazunori Takagi

Abstract

Under varjous conditions, I evaluated masticatory muscle tone by recording vertical dimension and velocity of mandjbular movement with electric stimulation. Ten stimulations were applied with the mandible in the rest position. The descending dimension and maximum velocity of descent were measured. Both parameters were lower in temporomandibular disorder (TMD) patients than in healthy subjects. Both of these values were higher after treatment for TMD than before treatment, and the values after treatment became similar to those in healthy subjects.
