Reliability and predictive value of the electrically evoked auditory brainstem response

L R Aubert1, G P Clarke

Summary

The electrical auditory brainstem response (EABR) threshold at low pulse rates poorly predicts psychophysical thresholds at high pulse rates in cochlear implant patients. Caution and correction formulas are needed when using EABR for electrode mapping.

Area of Science:

  • Audiology
  • Neuroscience
  • Biomedical Engineering

Background:

  • Cochlear implants (CIs) are crucial for hearing restoration in adults.
  • Electrode mapping optimizes CI performance by determining appropriate stimulation levels.
  • Electrical auditory brainstem response (EABR) and psychophysical thresholds are used in mapping.

Purpose of the Study:

  • To assess the reliability and predictive value of low-pulse-rate EABR thresholds compared to high-pulse-rate psychophysical thresholds for adult CI electrode mapping.
  • To evaluate the correlation between EABR and psychophysical thresholds at similar and dissimilar pulse rates.

Main Methods:

  • Eight experienced adult cochlear implant users participated.
  • The study compared low-pulse-rate EABR thresholds with high-pulse-rate psychophysical thresholds.

  • Correlation coefficients were calculated to assess the relationship between different threshold measures.

    • Main Results:

    • High correlations (≥0.90) were found between EABR and psychophysical thresholds at like pulse rates.
    • Correlations were significantly poorer when comparing low-pulse-rate EABRs to high-pulse-rate psychophysical thresholds.
    • The best correlation (0.75) was observed between a 30-Hz EABR and a 500-Hz psychophysical threshold.

    Conclusions:

    • Low-pulse-rate EABR thresholds are poor predictors of high-pulse-rate psychophysical thresholds used in adult CI electrode mapping.
    • EABR should be used cautiously as a clinical tool for setting CI electrodes.
    • Application of appropriate correction formulas is recommended when utilizing EABR for electrode mapping.
