Research
study with controls |
| Subjects |
21
males, 7 females; ages 16-68; 1.8-26.7 months post-onset
Gender-matched, age-matched, primary language-matched
controls |
| Diagnoses |
TBI
Normal controls |
Speech
Condition |
Dysarthria
(9)
No dysarthria (19) |
| Purpose |
To
document the diadochokinetic rate in persons with TBI
To determine which diadochokinetic rate variables distinguish
the TBI subjects from their matched controls
To determine the test-retest reliability of the diadochokinetic
rate variables |
| Methods |
Diadochokinetic
rate was measured using the Speech Performance Measurement
System (SPMS) which is an acoustic, computer-driven data
acquisition and management system
The subject's acoustic signal was recorded twice, and
the best result was assessed for the number of syllables
per second
Diadochokinetic rate was measured for these 16 syllables
repeated as fast as possible for 5 seconds: pa, ba, fa,
va, th, tha, ta, da, ye, ya, ka, ga, sa, na, ch, ja
Twelve subjects were retested approximately a week later
to determine test-retest reliability |
| Results |
13/16
of the diadochokinetic rate variables for the TBI group
and 12/16 for the control group had at least substantial
test-retest reliability
There are differences in diadochokinetic rate for people
with and without dysarthria and with TBI
The diadochokinetic rate variables cha, ta, da, and ba
determined group membership in 82% of the cases |
Treatment
Implications |
Only
cha, ta, da, and ba need to be used diagnostically in
assessing people with TBI
Diadochokinetic rate is important in quantitatively assessing
motor speech deficits in TBI |
