Why might a clinician use rate/rhythm therapy in AOS?

• A. To improve timing, sequencing, and fluency by pacing speech with boards or metronomes.
• B. To strengthen tongue muscles through resistance exercises.
• C. To reduce vocabulary size to simplify articulation.
• D. To teach handwriting as a primary compensatory strategy.

Answer: (B)

Rate/rhythm therapy focuses on timing and sequencing in speech. In apraxia of speech, the planning and programming of how to move the articulators is disrupted, so producing smooth, accurate sequences of sounds can be challenging. Providing an external rhythm—like a metronome beat or a pacing board—slows speech and gives the motor planning system time to organize each step of the sequence. This pacing helps align the articulatory movements to a regular tempo, improving timing, transitions between sounds, and overall fluency.

This approach is not about strengthening tongue muscles, which would involve resistance training. It also isn’t about simplifying vocabulary or teaching unrelated skills like handwriting. The core idea is that a steady rhythm aids the planning and production of speech by stabilizing timing and sequencing.
