Abstract
We have experienced a therapy for one child who had severe mental retardation and showed a speech disability. He was eager to express his thought by means of non-verbal communication such as gesture and finger pointing. The purpose of the training was to encourage him to speak. We made use of some techniques of the methodology of global and dynamic structuring for speech therapy. They were “Tonae-uta” and “Shintairizumu-undo”. After one-year's therapy, the clarity of his speech had improved and he was able to express his thoughts and desires in his own words. The result of this training showed that the use of “Tonae-uta” might have been effective in his speech improvement.
