Disordered speech can present with rhythmic problems, impacting on an individual's ability to communicate. Effective treatment relies on the availability of sensitive methods to characterize the problem. Rhythm metrics based on segmental durations originally designed for cross-linguistic research ha

RATIONALE: Orolingual motor deficits, such as dysarthria and dysphagia, contribute to increased morbidity and mortality in the elderly. In preclinical studies, we and others have reported age-related decreases in tongue motility in both F344 and F344/BN rats. The fact that these deficits are associa

difficulty in articulating words due to disease of the central nervous system　(⇔dysphasia)

Dysarthriaはかつては構音器官のレベルで生じる不完全な構音articulationの障害と定義された。しかし、その後、発声発語器官全体の(あるいはいずれかの)レベルで生じるspeechの障害として拡大して理解されるようになり、現在では広く共通の理解に至っている。すなわち、dysarthriaを「構音の障害」としてとらえる解釈は古典的定義であり、「speechの障害」としてとらえる解釈は今日の正しい定義である。(かつてわれわれはDysarthriaを「構音障害」と呼んでいた、といえる新たなる時代を迎えよう:小島氏への異論西尾正輝　より抜粋)
