聴覚過敏がありコミュニケーションが困難な子ども1例への〈S-S法〉と脱感作の応用

Application of desensitization and the Intervention Program for Language Retardation based on Sign-Significate Relations to a child with hyperacusis and communication disorder

　聴覚過敏があり，環境音に対し耳を塞ぎ，泣くことが主な表出であった子ども1例に対し，楽器を鳴らす脱感作療法を適用し，その効果を検討した．

　言語未習得児であったため，国リハ式記号形式-指示内容関係〈S-S法〉を用いて言語発達遅滞訓練も実施し，記号形式や指示内容関係となりうる材料(身振り，音声，文字，実物，機能的操作)などのうち，機能的操作による事物の基礎概念の形成と，聴覚過敏症への脱感作療法および物媒介コミュニケーションの関係を分析した．その結果，聴覚過敏が軽減し，表情などの非言語的コミュニケーションが良好になった．聴覚過敏を伴う言語発達遅滞児における物媒介コミュニケーションによる〈S-S法〉と脱感作療法の応用の有用性が示唆された．

　This study reports the effect of a desensitization program using musical instruments on a child with hyperacusis, whose expression was limited to crying and covering his ears in response to environmental sounds.

　Because he was nonverbal and without language signs, the Intervention Program for Language Retardation based on Sign-Significate Relations (known as S-S Method) was also used.　Changes were observed in the formation of basic object concepts based on object manipulation, as well as in the effect of desensitization for hyperacusis and development of object-mediated communication.　As a result, his hypersensitivity to sounds was reduced and non-verbal communication, such as changes in facial expression, was improved.　Use of musical instruments for alleviating hyperacusis and object-mediated communication based on S-S Method were found to be effective.
