Outline of Final Research Achievements

In the present study, we sesearched for new quantitative parameters that are useful to evaluate rehabilitation for stroke patients. We found five parameters: 1) precision of the predictive controller, 2) precision of the feedback controller, 3) co-contraction of agonists and antagonists, 4) synkinesis of proximal muscle activities, 5) power of "microsteps" (i.e. high frequency (3-8Hz) noise during voluntary movements). These parameters are quite useful to visualize functional state of stroke patients for a long period.
