Q

What does the American-Speech-Language Hearing Association (ASHA) Preferred Practice Patterns for the Profession of Speech-Language Pathology state:

A

All patients/clients with voice disorders must be examined by a physician, preferably in a discipline appropriate to the presenting complaint. The physician’s examination may occur before or after the voice evaluation by the clinician (p.99).

90
What is the durational measure: MPT?
Maximum Phonation Time
91
Name an example of a durational measure.
s/z ratio
92
What is maximum phonation time?
- an indirect index of laryngeal airflow - it is the greatest length of time over which the /a/ vowel can be sustained at the patient's most comfortable pitch and loudness following a maximal inhalation
93
How many MPT trials are conducted? Which one is reported?
3 and the longest
94
Name another indirect index of laryngeal airflow except for MPT?
s/z ratio
95
How do you obtain an s/z ratio?
the clinician asks the patient to first sustain the /s/ as long as possible, and then to sustain the /z/ as long as possible, each at a normal pitch and loudness following a maximal inhalation
96
What does the clinician usually do during the s/z ratio assessment? How is it measured?
- clinician provides verbal encouragement | - the longest /s/ and longest /z/ from one of the three alternating /s, z/ trials is used to calculate the ratio

98
A high s/z ratio is......?
