Outline of Final Research Achievements

3D motion analysis was performed on the finger-nose test.
The relative velocity between the second finger and the target was calculated for the finger nose test, and it was found that in patients with spinocerebellar degeneration, the velocity tended to increase slightly at the time immediately before the target. In normal subjects and the patients with Parkinson's disease, the speed tended to decrease immediately before the target.The relative acceleration between the second finger and the target in the finger nose test was calculated, and it was found that in patients with spinocerebellar degeneration, the acceleration tended to increase slightly even at a short distance to the target. In normal subjects and patients with Parkinson's disease, the acceleration tended to decrease near the target.
