| Research Abstract |
We developed a navigation system for treatment of neurological patients based on the evaluation of outputs from predictive and feedback (FB) controllers. By using this system, we evaluated a visually-guided tracking wrist movement in cerebellar patients and Parkinson`s disease (PD) patients. In particular, the cerebellar patients demonstrated deterioration of both controllers along with severity of their ataxia. Therefore, we found that the cerebellum contributes to both controllers. On the other hands, it was difficult to extract the characteristics for the PD patients based on the two controllers. However, we identified the third component of the wrist movement that belonged to even higher frequency range (=F3 domain, 4-8Hz). The wrist tracking movement of PD patients showed marked increase in the F3 domain. Consequently, we found that our method provides a quantitative tool to evaluate neurological disorders in terms of properties of motor controllers.
