final exam Flashcards
voice disorder
disorders of vocal disturbances where there is a problem initiating or controlling the voice
what is included with voice production
pitch - frequency of vibration
loudness - amplitude
quality - complexity
factors that influence voice
dysphonia, nonorganic, and organic factors
dysphonia
any condition of poor or unpleasant voice quality
nonorganic factors
aphonia - absence of audible phonation
emotional problems - stress or anxiety
organic factors
laryngitis, tumors, paralysis, vocal fold webbing, etc.
organic voice problems
pathology of disease affecting larynx or vocal tract
-most alter mass of vocal folds
-ex. edema, tumors, webbing, etc.
functional voice problems
due to faulty voice use or psychogenic factors
functional voice problems
due to faulty voice use or psychogenic factors
-vocal abuse or vocal hygiene
-sypmtoms range from whispered, breathness, hoarse, variation in pitch and loudness
vocal hyperfunction
includes any voice disorder characterized by excessive laryngeal tension or overly forceful closure of the vocal folds (vocal abuse or misuse)
vocal hypofunction
includes voice disorder characterized by incomplete closure of the vocal folds (neurologic disorders such as unilateral vocal fold paralysis, myasthenia gravis, and muscular dystrophy)
dysphagia
swallowing disorder characterized by the difficulty moving food from the mouth to the stomach
phases of a swallow
anticipatory stage : sensory information
oral stage : preparatory phase and transport phase
pharyngeal stage : protect the airway and directs the bolus towards the stomach
esophageal stage : as the bolus passes through the upper esophageal sphincter, the larynx lowers and moves backward to resume breathing
acute dysphagia
resulting from a stroke or some other incident
gradual deterioration dysphagia
resulting from a progressive disease
what should be considered when developing a dysphagia plan
positioning, cueing, bolus modification, and swallowing strategies
treatment goals for dysphagia
-prevention of aspiration, malnutrition, and dehydration
-re establishment of oral intake of food and liquid
postural techniques for dysphagia
chin down, chin elevated, head turn, head tilt, and lying down
maneuvers for dysphagia
supraglottic swallow, super-supraglottic swallow, effortful swallow, mendelson maneuver, and masako manuever
exercises for dysphagia
shaker exercises, tongue exercises, and transference of treatment effects
other considerations for dysphagia treatment
sensory stimuli, dietary changes, medical procedures, and neuromuscular electrical stimulation
what is the main difference of swallows for adults compared to pediatrics
adults had a normal swallow and children have yet to acquire normal eating skills
aspiration
when food or liquid enters a person’s airway and eventually the lungs
dysarthria
impaired ability to execute motor movement (weakness of oral muscles)
subsystems for dysarthria
respiration, phonation, resonance, and articulation
respiration treatment
establish consistent controlled exhalation to support speech
phonation treatment
efficient vocal fold closure during speech
resonance treatment
decrease hypernasality by generation of intraoral pressure
articulation treatment
improved speech sound production with constraints of impairment
aphasia
language disorder as a result to brain damage
-impaired comprehension and/or extension
two broad types of aphasia
fluent and non fluent
fluent aphasia
impaired comprehension (wernicke’s area), normal or fast rate of speech, unaware of their errors
-wernicke’s
-transcortical sensory
-conduction
-anomic
non fluent aphasia
comprehension varies, reduced vocabulary, agrammatic, impaired articulation/rate, usually aware of their errors
-broca’s
-transcortical memory
-global
FAST for a stroke
Face - smile and observe if one side of the face drops
Arms - raise both arms and see if one drops
Speech - have them count and notice if speech is slurred or strange
Time - call 911 if any of the above is a yes
speech characteristics with aphasia
aphasia - word finding difficulties
paraphasia (phonemic and semantic) - substitution
perseveration - inappropriate continuation of a response
subpropositional speech - grammar is fluent by over learned phrases are used on a higher scale
agrammatism - syntactic deficit of the omission of function words
