In AOS assessment, why differentiate from non-speech oral apraxia (NVOA) or verbal/motion apraxias?

• A. Because co-occurring non-speech oral apraxia can confound interpretation of speech motor planning
• B. Because AOS cannot co-occur with limb apraxia
• C. Because non-speech apraxia can help differentiate from pure speech planning deficits
• D. Because differentiation has no clinical value

Answer: (C)

Distinguishing AOS from non-speech oral apraxia and other verbal/motion apraxias helps you see whether the problem is specific to planning speech movements or part of a broader motor planning difficulty. If a person shows trouble with planning and sequencing for speech but can perform non-speech oral gestures relatively normally, this points to a speech-specific planning deficit—precisely what AOS involves. If non-speech oral movements are also impaired, it suggests a broader apraxic syndrome that affects multiple actions, which changes both diagnosis and treatment approach. This differentiation is clinically valuable because it guides therapy targets and prognosis more than simply noting some apraxic issue. It’s not accurate to claim AOS can’t co-occur with other apraxias, and saying differentiation has no clinical value wouldn’t fit the practical benefits of a targeted assessment.
