Jaw movement patterns were examined longitudinally in a 3-year-old male with childhood apraxia of speech (CAS) and compared with a typically developing control group. The child with CAS was followed for 8 months, until he began accurately and consistently producing the bilabial phonemes /p/, /b/, and /m/. A movement tracking system was used to…

Three kindergarten children with residual articulation problems, as evidenced by the consistent misarticulation of "s," participated in a therapy program which employed simultaneous training of "s" in the initial, medial, and final positions of familiar words.

This paper reviews research designs and strategies found in 63 reports evaluating effectiveness of treatment of articulation or phonological disorders, published in the 1970s and 1980s. Characteristics analyzed include type of disorder, type of reliability, follow-up phase, subject selection and description, type of dependent variable, age levels,…
