PURPOSE: To determine reliability, diagnostic values, and minimal detectable
change scores, 90% confidence (MDC90) of pediatric clinical tests of vestibular
function. METHODS: Twenty children with severe to profound bilateral
sensorineural hearing loss and 23 children with typical development, aged 6 to 12
years, participated. The Head Thrust Test, Emory Clinical Vestibular Chair Test,
Bucket Test, Dynamic Visual Acuity, Modified Clinical Test of Sensory Interaction
on Balance, and Sensory Organization Test were completed twice for reliability.
Reference standard diagnostic tests were rotary chair and vestibular evoked
myogenic potential. Reliability, sensitivity, specificity, predictive values,
likelihood ratios, and MDC90 scores were calculated. RESULTS: Reliability ranged
from an intraclass correlation coefficient of 0.73 to 0.95. Sensitivity,
specificity, and predictive values, using cutoff scores for each test
representing the largest area under the curve, ranged from 63% to 100%. The MDC90
for Dynamic Visual Acuity and Modified Clinical Test of Sensory Interaction on
Balance were 8 optotypes and 16.75 seconds, respectively. CONCLUSIONS: Clinical
tests can be used accurately to identify children with vestibular hypofunction.
