| Outline of Final Research Achievements |
T2 value of masseter muscles were higher on painful side based on painless side with temporomandibular disorder. Also there was significant related to oppressive pain with T2 value, but no relation to pain on motion. The reason does not seem to depend on direct tissue damages, because the difference cannot detect on T2 weighted image that will be affected with proton density. It might be influenced by blood flow rates and/or free water ratios in the interstitial fluid. And there were significant differences of T2 value on masticator muscles of patients with trigeminal neuralgia independent on the trigger point, so the pain might effect on blood flow rate and condition of the interstitial fluid path through the autonomic nervous system.
