1. tool in screening people at risk for laryngeal pathology.
2. assessment of patients visiting the family doctor with complaints of hoarseness.
3. supplementing diagnostic evaluation of vocal problems.
4. monitoring voice changes over time. pg. 157
T/F: Physiological health has no effect on the aging voice?
False: physiological health is an extremely important variable in aging of the voice. pg. 157
Jitter and shimmer measures have ben used to document vocal function in patients with what type of communication disorders?
neurologicial, such as ALS and Parkinsons; mechanical, such as trach intubation damage; laryngeal cancer, funcational voice problems and stuttering pg. 158
In patients with _______, jitter and shimmer values indicate a degeneration in the speech muscles before the degeneration is actually heard as impaired speech .
ALS pg. 158
A progressive neurological disease in which all motor functions of the body deteriorate due to damage to the motor nerves that supply all the voluntary muscles of the body.
ALS
The underlying pathophysiology of _______ is the reduction in the neurotransmitter dopamine.
Parkinsons
Acoustically, patients with Parkinsons show (higher/lower) Fo and a (higher/lower) jitter; (lower/higher) intensity; (increased/decreased) phonational range; and (increased/decreased) dynamic range
A new tx for Parkinson's in which suitable fetal cells are transplanted in the appropriate sit in the patient's brain. The is an aim to replenish the missing dopamine.
Define: endotracheal intubation
Whenever a person has a general anesthetic, a breathing tube is inserted into their trachea through the larynx. pg. 159
Removal of the trach tube is called?
extubation
Severe damage from extubation can result in _____ ?
aphonia pg. 159
Greater shimmer and jitter levels were evident in the patient's voice after short-term intubation which ranges from ___ to ____ hours.
1.5 to 23.5 hours pg. 159

4.34 and 1.52
Voice problems not caused by disease, growths, trauma, or other neurological or organic problems?
Functional Voice Problems pg: 160
Researcher found the jitter values are _____ between those who stutter and those that do not? and shimmer values between each?
jitter: the same
shimmer: higher for children who just began to stutter than for the nonstuttering children
Objective measures for voice quality can be used for 2 reasons?
1. eval of problem can be more precise for more appropriate tx is used.
2. assess and quantify tx for patients and insurance companies
Objective measures are used to sort out which aspects of voice quality are involved in a voice problem. T/F
True
High-pitched voice can be associated with nodules, tumors on the vocal folds, and vocal fold paralysis. T/F
False, caused by low-pitched hoarse voice.

Optimum Pitch
Common treatment alleviate laryngospasms Adductor Spasmodic dysphonia?
Botox injections
Adductor spasmodic dysphonia
Neurological voice disorder causing spasms of the vocal folds to adduct, making it difficult to set them in vibration.
Voice quality of individuals with adductor spasmodic dysphonia is _______?
strained-strangled
Voice quality after Botox injections is ______ for the first week or two.
breathy and weak
The effects of the Botx injections are permanent. T/F
False, clients are reinjected every 3-6 months depending on how long the effects last.
Designed to increase the activity of the respiratory musculature to generate increase volumes and subglottal pressure for speech.
