Abstract

Masticatory muscle tone was investigated by analyzing vertical mandibular movement with electric stimulation. Healthy subjects and patients with type I TMD wereexamined. Under various conditions, masticatory muscle tone was evaluated by recording vertical dimension and velocity of mandibular movement.<BR>The results were as follows:<BR>1. Ten stimulations were applied with the mandible in the resting position. The descending dimension and maximum velocity of descent were measured.<BR>2. The mental anxiety of the subjects only slightly affected the mandibular movement with electric stimulation.<BR>3. Both parameters were lower in TMDpatients than in healthy subjects.<BR>4. Both of these values were lower before treatment for TMD than after treatment, and the values after treatment became similar to those in healthy subjects.
