| Research Abstract |
The long term aim of our project is to elucidate mechanisms potentially underlying awake bruxism which is characterized by frequent tooth-clenching. In this term, we investigated comparison of the influence of visual feedback between spinal and trigeminal muscle activity, and the effect of repeated and standardized tooth clenching tasks on corticomotor excitability as assessed by motor evoked potentials in the masseter muscle. Our findings suggest that influence of visual feedback was different contributes significantly to the control of both between spinally-innervated and trigeminally-innervated muscles, and neuroplasticity in the corticomotor control of the masseter muscles evoked by repeated tooth-clenching tasks.
