Childhood apraxia of speech and multiple phonological disorders in Cairo-Egyptian Arabic speaking children: language, speech, and oro-motor differences.
Childhood apraxia of speech is a neurological childhood speech-sound disorder in which the precision and consistency of movements underlying speech are impaired in the absence of neuromuscular deficits. Children with childhood apraxia of speech and those with multiple phonological disorder share some common phonological errors that can be misleading in diagnosis. This study posed a question about a possible significant difference in language, speech and non-speech oral performances between children with childhood apraxia of speech, multiple phonological disorder and normal children that can be used for a differential diagnostic purpose. 30 pre-school children between the ages of 4 and 6 years served as participants. Each of these children represented one of 3 possible subject-groups: Group 1: multiple phonological disorder; Group 2: suspected cases of childhood apraxia of speech; Group 3: control group with no communication disorder. Assessment procedures included: parent interviews; testing of non-speech oral motor skills and testing of speech skills. Data showed that children with suspected childhood apraxia of speech showed significantly lower language score only in their expressive abilities. Non-speech tasks did not identify significant differences between childhood apraxia of speech and multiple phonological disorder groups except for those which required two sequential motor performances. In speech tasks, both consonant and vowel accuracy were significantly lower and inconsistent in childhood apraxia of speech group than in the multiple phonological disorder group. Syllable number, shape and sequence accuracy differed significantly in the childhood apraxia of speech group than the other two groups. In addition, children with childhood apraxia of speech showed greater difficulty in processing prosodic features indicating a clear need to address these variables for differential diagnosis and treatment of children with childhood apraxia of speech.
