Type
of
Study |
Case
studies |
| Subjects |
53
men; 27 women; mean age 26; mean months most onset males-48
months, females-56 months; consecutive admissions |
| Diagnoses |
Severe
TBI |
Speech
Condition |
Dysarthria
ranging from none to severe |
| Purpose |
To
determine the incidence of velopharyngeal deficits following
TBI
To determine the relationship between velopharyngeal deficits
and dysarthria severity
To determine the relationship between velopharyngeal resistance
and perceived hypernasality |
| Methods |
Dysarthria
severity assessment-oral peripheral evaluation, conversation
speech sample, diadochokinetic rates, speech breathing
analysis, voice evaluation, intelligibility testing,
CAIDS, phonetic contrast test
Instrumentation-pneumotachograph and differential pressure
transducer |
| Results |
Half
of subjects had reduced velopharyngeal resistance
Subjects with mild or absent dysarthria did not have velopharyngeal
impairment
Subjects with severe dysarthria had very low velopharyngeal
resistance
48% had reduced velopharyngeal airway resistance
Some discrepancies between perceived hypernasality and
velopharyngeal airway resistance |
Treatment
Implications |
Velopharyngeal
airway resistance deficits common after TBI and correspond
to dysarthria severity
Relationship between velopharyngeal functioning and dysarthria
is complex and should be paid attention to |
