Abstract
This study investigated the contribution of lateral movement to articulatory (in)stability. Using an optical three-dimensional movement analysis system, articulographic data on jaw movements were collected on the reiterated productions of the words /spa:/ and /pa:s/ (consisting of the same sequence of speech sounds but with a different syllabic structure) of 18 adults, 16 5- to 6-year-olds typically developing children, and five children (ages, 4-7 years) with a variety of speech sound disorders (SSDs).
Results of earlier studies showed that in the midsagittal plane, articulatory movement trajectories become more stable with age and during linguistic and phonemic development. The current results on the stability of jaw movements in the coronal plane corroborate these findings. Furthermore, the results indicate deviances from the norm data for the children with SSDs; however, in the midsagittal plane, no deviances were found for jaw movements for children with SSDs and subtype childhood apraxia of speech compared with control participants in a previous study. These results suggest that assessing lateral movement stability is important for the profiling of SSDs and might provide direct starting points for therapy planning.
