| Research Abstract |
The purpose of this study is to produce a quantitative evaluation for the severity of Parkinson's disease. To this end, we propose a novel simultaneous evaluation method for finger motion properties, muscle forces and autonomic nervous activity during finger tapping movements. As a consequence of this study, we have successfully developed (i) an estimation method of finger motion and forces between two fingers using a magnetic sensor based on fingerpad stiffness characteristics, (ii) an evaluation index of autonomic nervous activity from arterial viscoelastic properties (called a log-linearized arterial viscoelastic index) during finger tapping movements, and (iii) a novel system for evaluating motor function and supporting rehabilitation training of finger tapping movements. The results suggest that the proposed method can evaluate motor function based on muscle forces and nerve activity, and is expected to be applied to other types of movements.
