Wat Doet Een Bijtblok bij Spraakontwikkelingsdyspraxie?
This article describes a study on the effects of a bite-block on speech of children with developmental apraxia of speech (DAS) and normally developing children. The speech of children with DAS is characterised by articulatory abnormalities and is often unintelligible due to a large number of phonemic speech errors (substitutions and omissions). The bite-block is a method to study the compensation mechanisms of speech in order to answer the question whether there is a disturbance at the level of speech-motoric output. The results show effects of the bite-block for normally developing children as well as for children with DAS. The speech of children with DAS shows stronger effects of the bite-block than the speech of normally developing children. In conclusion, we can say that the speech-motoric output of children with DAS is disturbed.
