What do you need to know about the diadochokinetic rate?

How is the SLP used in diadochokinetic testing?

Your SLP will compare the results of your test to standard normalcy measurements, using the DDK rate system. For example, a typical 10-year-old produces 20 repetitions of the syllable “puh” in 3.7 seconds. Your SLP will use any deviations from the standard normalcy measurements to assess and diagnose your condition.
