Test-retest reliability in clinical electrocochleography. 1976

L M Bergholtz, and R E Hooper, and D C Mehta

The intratest test-retest reliability in clinical electrocochleography was studied by measuring the difference between amplitude of the test and retest and latency of the test and retest. Eighty-four comparisons were made in 40 patients with different types of hearing losses. The type of hearing loss and whether test and retest were performed in sequence or not did not affect the variability of the amplitude. The test and retest correlation between amplitudes was good. Small amplitudes mainly found near the action potential (AP) "threshold" showed less absolute variability than larger amplitudes found at higher intensities. The correlation between the intratest latencies was excellent. The latency showed less variability at higher intensities than near AP "threshold".
