How does therapy intensity influence outcomes in AOS?

• A. Therapy timing is the only important factor
• B. Frequency of practice has no effect
• C. Higher intensity and earlier therapy generally improve outcomes
• D. Longer therapy without intensity is best

Answer: (C)

In this area, the key idea is that how much and how soon you practice matters for motor speech learning. AOS improves when therapy is delivered with higher intensity and started earlier because you get more repetitions of correct articulatory gestures in a shorter time frame. This abundant, targeted practice helps reshape the neural pathways responsible for speech and supports quicker gains in accuracy and fluency, with skills more likely to transfer to daily communication. Starting therapy early takes advantage of neural plasticity, reducing the chance that faulty patterns become entrenched. Extending therapy without increasing the amount of meaningful practice tends to yield slower progress, since the brain isn’t receiving enough correct repetitions to drive meaningful change. So, higher intensity and earlier therapy generally lead to better outcomes.
