Voice Disorder Assessments Flashcards
Three areas to consider when assessing voice
Laryngeal integrity, Glottal closure, Vocal fold pliability
What is laryngeal intergrity
general appearance and health
What is glottal closure
adductor and abductor capacity, including
thick and thin vocal fold compression
What is vocal fold pliability
Free movement of mucosal edge
What does a direct laryngoscopy measure
laryngeal intergrity
what does an indirect laryngoscopy measure
integrity and closure
what does a continous light only flexible videoendoscopy measure
integrity, closure
What does a stroboscopic light only flexible videoendoscopy measure
integrity, closure, pliability
What are the 5 steps you would take for a clinical evaluation of a a voice
- Interviewing
- Observing
- Describing the voice
- Comparing observations to standards and normal
values - Integrating information to determine treatment
Important questions to ask during interview for clinical evaluation of a voice
Occupation/ hazards
Recreational/ Social voice use (i.e are they very social, are they a singer, do they play a team sport etc)
Respiration health/ other related illness
Smoker
Psychological issues
What to ask about clients description of the problem
- Onset/history
- Effect of the problem
- Duration
- Variability/consistency
- Perception of the cause
- Effect of the voice problem
ard protocols and measures
what is normal maximum phonation time for an adult (f & M)
Females: 15-25 seconds
Males: 25-35 seconds
What is purpose of measuring s:z ratio
Assessing ability to produced voiced versus voiceless sounds.
What causes a decrease in the z part of s:z ratio
Disturbances in glottic function are reflected by a decrease in the duration of z (as a consequence of inadequate vocal cord closure and subsequent air escape)
How to evaluate nasal resonance
get client to sustain /i:/ sound with and without obstruction of nasal airflow
What is a Auditory-perceptual voice profiles
System to assess clients vocal qualities, i.e GRBAS or CAPE-V
What does intensity (dB) measure
Volume, noise level
What is fundamental frequency
the frequency at which vocal folds vibrate,
What is shimmer
Assessment of amplitude variability, higher shimmer indicates possible voice disorder, can be used to evaluate voice quality and monitor changes over time
What is jitter
Measures variation of fundamental frequency, higher jitter indicates greater pitch variability associated with voice disorders.
Normal shimmer %
3-4%
Normal jitter %
1-2%
What is pitch measured in
Measured by fundamental frequency
What does dB measure
Loudness
