Speech consistency in apraxia of speech I
What is it about?
This was our first study to address the controversy about whether speech consistency helps diagnose apraxia of speech after stroke. We compared aphasia with apraxia of speech to aphasia with phonemic paraphasia. 32 people participated. We formed the comparison groups based on quantitative measures rather than clinical impression. The speech task was to say the same word five times in a row. Our team measured error consistency for all the syllables.
Why is it important?
The diagnostic recommendations at the time said that people with apraxia of speech produce more consistent speech errors than people with aphasia + phonemic paraphasia. Our results did not support this. We concluded that more research was needed and that diagnostic recommendations may need to be revised.
