SLP Voice, Resonance, and Motor Speech 4

Question 1

The s/z ratio is used clinically to assess:

Accepted Answer

Glottal pathology by comparing fricative durations requiring and not requiring voicing

Answer

The s/z ratio compares maximum /s/ and /z/ phonation times; a ratio greater than 1.4 suggests laryngeal pathology affecting voicing.

Question 2

Which resonance disorder is characterized by nasal air emission and reduced intraoral pressure during pressure-sensitive consonants?

Accepted Answer

Hypernasality with VPI

Answer

Velopharyngeal insufficiency (VPI) causes hypernasality plus audible or inaudible nasal air emission, reducing pressure for consonant production.

Question 3

A 55-year-old patient presents with a unilateral vocal fold paralysis in the paramedian position. Which surgical intervention restores glottic closure most efficiently?

Accepted Answer

Type I thyroplasty (medialization)

Answer

Type I thyroplasty medializes the paralyzed vocal fold by inserting an implant through a window in the thyroid cartilage, improving glottic closure.

Question 4

In Lee Silverman Voice Treatment (LSVT LOUD), the primary target behavior is:

Accepted Answer

Increased vocal loudness through recalibrated sensory awareness

Answer

LSVT LOUD targets increased vocal effort and loudness, leveraging recalibration of sensory feedback in hypokinetic dysarthria from Parkinson's disease.

Question 5

Bernoulli effect during vocal fold vibration refers to:

Accepted Answer

Decreased pressure between approximated vocal folds causing passive adduction during airflow

Answer

As air accelerates through the narrowed glottis, pressure drops (Bernoulli effect), drawing the vocal folds together and contributing to cyclical vibration.
