PURPOSE: To compare orofacial praxis abilities in children with typical phonological development but with phonetic-phonological and phonological impairment. CASE REPORT: The patients comprised 29 children diagnosed with phonological disorders, 29 children with typical phonological development, and 24 children diagnosed with phonetic-phonological disorder. The following 2 praxis skill tests were applied: the Orofacial Praxis Test (Bearzotti, Tavano, and Fabbro, 2007) and the Bucofacial Articulatory Praxis test (Hage, 2000). Further, the Stomatognathic System Assessment and Child Phonological Evaluation (Yavas, Hernandorena, and Lamprecht, 1991) were used. The Chi-Square test was used for the statistical analysis. The results showed that the children in the phonetic-phonological disorder group had the worst performance on the orofacial praxis texts compared to the other 2 groups. CONCLUSION: Children with phonetic-phonological disorder have more difficulties in orofacial praxis than children with phonological disorder and typical phonological development.
