Outline of Final Research Achievements

The subjects were three dysarthria patients. The type of dysarthria of subjects was flaccid dysarthria and mixed dysarthria (flaccid and ataxic, spastic and ataxic). The data were analyzed after measurement. The range of ascending and descending movement of the posterior tongue with visual biofeedback was larger than that without visual biofeedback. The coefficient of variation for these movements with visual biofeedback was smaller than that without visual biofeedback. Patients said that we were able to understand the movement of the posterior tongue with visual biofeedback.
