| Summary: | Purpose
The present study investigated the intra-subject variability in auditory brainstem responses (ABRs) recorded using a vertical montage and compared the results with the ABRs recorded using an ipsilateral montage.
Methods
A total of 31 adults with normal hearing were involved in this study. The ABRs from vertical and ipsilateral montages were recorded at 80, 50, and 30 dBnHL using 0.1 ms click stimuli on the right ear with a stimulus rate of 19.1 Hz. Each participant was tested in two clinical sessions with a 7-day interval between sessions. The ABR results between the sessions and montages were compared and statistically evaluated.
Results
The ABR results were generally consistent between the two sessions in both the ipsilateral and vertical montages. The test–retest mean differences (test session 2 minus test session 1) between the ipsilateral ABR and vertical montage ABR results were also similar. Coefficient of variation values indicated that more variability was associated with smaller amplitude ABRs than higher amplitude ABRs.
Conclusion
The ABR recorded through the vertical montage had, in general, a similar reliability to the ABR recorded using the ipsilateral montage. |
