Consider relationship between SRT and PTA

Consider word recognition below 50% as a red flag for retrocochlear pathology.

Compare SRT at each ear for significant asymmetry.

Use SPRINT chart to compare PB min at each ear for significant asymmetry

Screen for rollover by presenting word recognition at two different presentation levels, including UCL-5 as one of the levels.

A

Use the SPRINT chart to compare PB max scores obtained at each ear for significant asymmetry

Consider word recognition (PB max) below 80% with a PTA of 30 dB or better as a red flag for retrocochlear pathology.

Screen for rollover by presenting word recognition at two different presentation levels, including UCL-5 as one of the levels.

55
Q

Recall that there are several recorded word lists that audiologists use for word recognition testing. NU-6, W-22, and CID words lists are commonly used. We have been using the NU-6 word lists in class.

True or false: The SPRINT chart is based on NU-6 words lists and can not be used for other word lists.

A

True

56
Q

Recall that there are several recorded word lists that audiologists use for word recognition testing. NU-6, W-22, and CID words lists are commonly used. We have been using the NU-6 word lists in class.

True or false: A rollover index of .25 being suggestive of retrocochlear pathology applies to using NU-6 word lists and does not apply to other word lists.

A

true

57
Q

Imagine you are testing a patient following a medical procedure that could impact word recognition ability. The patient has moved from another location and you have the audiogram that was completed before the procedure. You are doing the follow-up testing so the scores obtained before and after the procedure can be compared to see if a significant drop has occurred. You note that the previous audiologist used recorded materials and that they administered 1/2 of a word list to each ear. Which one of the scores below would you be MOST concerned about as NOT being a reliable baseline measurement due to test-retest variability?

A

64%

58
Q

For the previous question, what could the previous audiologist have done to improve the reliability of the word recognition score?

A

Present a full word list of 50 words to each ear
