遠隔構音訓練により側音化構音に改善を認めた成人症例

An adult case whose lateral lisp improved by tele-rehabilitation

　成人の側音化構音を呈する機能性構音障害例に対して，初回面接から構音訓練，最終評価までの一連の言語聴覚療法をインターネットのWeb会議サービスを用いて遠隔訓練し，効果を上げた症例を経験した．症例は22歳の女性で，「実習に行くまでに発音を治したい」という主訴により訓練開始となる．評価，訓練ともにWeb会議サービスZoomを用いて行った．口腔顔面，舌に形態および神経学的異常は認めなかった．新版構音検査を実施し，[k，ɡ，ɾ]のイ段と拗音において側音化構音を認めた．初回評価開始から1か月後に最終評価を行い，当初認めた側音化構音は認めなくなったため遠隔訓練を終了とした．遠隔訓練は，画面越しという本来の構音訓練と異なる状況ではあるものの，対面での訓練と同様に機能性構音障害例の構音の改善に有用である可能性が示された．

　A series of speech therapy sessions was remotely provided using a free communication application on the internet to an adult case with a lateral lisp. The case was a 22-year-old woman, who wished to correct her pronunciation before going to clinical practicum. Both evaluation and training were conducted using the free communication app Zoom. Neither morphological nor neurological abnormalities were observed in her orofacial musculature including the tongue. A revised version of the Articulation Test was carried out, and a lateral lisp was found in the sounds [k, ɡ, ɾ]. One month after the initial evaluation, the second evaluation was performed. Since the initially recognized lateral lisp was no longer identified, the remote training was terminated. Although remote training does not allow direct observation and auditory judgement of the client's speech production, it was shown that it is useful for improving articulation to the same degree as face-to-face training.
