Outline of Final Research Achievements

While motor disturbance in Parkinson’s disease can affect innate, programmed processes, such as masticatory mandibular movements, the pathophysiology of such abnormalities remains unclear. This study applies digital analysis by motion capture methods and high-speed video signal processing that tracks three dots placed around the mouse for recording masticatory movements in Parkinson’s disease patients and control. In Parkinson’s disease patients, the amplitude and velocity of mandibular movements was reduced, the interval of masticatory cycle was extended. This study indicates that masticatory movement analysis is able to define and quantify abnormalities as a sign of Parkinsonism.
