Childhood Apraxia of Speech developmental speech patterns – a wide retrospective study


Patterns of a phenomenon define the entity. If one understands the patterns of the maze, he can find his way there. Patterns of colors on a dress will hold its characters and soul. Understanding the expressive patterns of a developmental syndrome enables treating it with success. It is true for treating Childhood Apraxia of speech (CAS) as well. CAS as motor-speech disorder involves difficulties in sounds production for speech purposes. The difficulties can be demonstrated in patterns that would be specific to CAS. Those patterns can distinguish one phenomenon from another.


A retrospective research was conducted based on 277 entry level evaluations of children diagnosed with CAS or suspected CAS who visited a private clinic between the years 2006-2013. The analysis included speech variables along background and environmental variables. This article is dealing with speech patterns of children with motor speech disorder. Among the patterns examined are vowels ladder, single syllable ladder,  Blowing and SSP, Oral motor and SSP, Consonant group ladder and Consonants Exploratory factor analysis.


The findings demonstrated the relationship and order of vowels, consonants and single syllables among Hebrew speaking children diagnosed with motor speech disorder. The Consonants Exploratory factor analysis gave validity to the existence of unique consonant groups.  


Further discussion regarding every result and its implication is included. Understanding the unique patterns of consonants and vowels strength among children with CAS can help the clinicians in the clinical decision making process and goals targeting.
